Getting rid of phytophthora in a polycarbonate greenhouse: 3 ways

Late blight in a polycarbonate greenhouse can destroy the entire crop Late blight is a fungal disease that is characterized by the appearance of black spots on fruits. The fight against an unpleasant disease must begin with the proper preparation and disinfection of the greenhouse. In addition, you need to periodically carry out the prevention of late blight.

Phytophthora is a real nightmare for vegetable growers. It is a fungus that infects plants. It is very difficult to get rid of it. For this, a full greenhouse disinfection should be carried out. You will need to replace the ground or remove the topsoil. But you can use and special tools that destroy the fungus.

Ways to get rid of phytophthora:

  • Chemical,
  • Physical (temperature),
  • Biological.

Greenhouse after the disease should be treated with chemical solutions. Suitable copper sulfate or potassium permanganate. They need to handle all the details and elements of the greenhouse. To do this, use the spray.

You can also use phytosporin. When working with him you need to follow the instructions of the instructions. They need to disinfect the surface of the greenhouse. This process should be carried out in a warm environment (10 degrees). If this figure is less, then disinfection will be ineffective.

Greenhouse after the disease should be treated with chemical solutions

Processing designs can be lime. Before work it must be repaid. When all the details are missed, the greenhouse needs to be ventilated. After 2 weeks, the procedure is advised to repeat.

Popularity has earned a way to fumigate a greenhouse with sulfur. This is not an easy job due to the hazard and toxicity of the substance. Sulfur should come in contact with alkali. After that, it should burn. But while sulfur should not be in contact with the metal.

Winter soil preparation:

  • The earth must be fertilized with humus and manure,
  • You should make a mixture of sand and sawdust in the ground,
  • Sometimes used fertilizers in the form of ash.

This primer also needs to be sanitized. For these purposes, a solution of potassium permanganate or copper sulfate is used. All work is quite laborious, but otherwise not to get rid of the pest.

How to process a greenhouse in the fall of late blight

Polycarbonate greenhouses can be disassembled for the winter. The design is strong enough to withstand bad weather. But at the end of October, a series of activities should be carried out to prepare the greenhouse for spring planting and to combat parasites.

Greenhouse processing includes:

  1. Remove all unnecessary items and tools. They should be disposed of or treated.
  2. Get rid of weeds. It is on them that the late blight lives.
  3. Required to remove the top layer of soil.
  4. The earth should be re-dredged and sanitized.
  5. The entire structure should be washed and processed.

The soil in the greenhouse must be periodically changed. To do this, remove 25 cm of soil. But sometimes it is difficult. That is why each season is required to remove the top layer of soil, which is 7-10 cm.

After that you should dig up the soil well. Removed soil, if it was infected with parasites, should be treated with bleach. 180 grams of the drug should be enough for 15 cm of soil. Use this land will be possible only after a year.

Greenhouse from late blight must be processed in the fall

Soil treatment with chemicals or boiling water can kill not only pathogens, but also all the nutrients that are present in the soil.

If the plants were infected with late blight, then after collecting them you can sow the greenhouse with mustard, beans or lupine. These cultures are sediratami. So the soil will recover and recover.

Processing the greenhouse in the fall is an excellent preventive measure against fungus. It will allow you to completely clean all structural elements from the presence of a pest. The greenhouse should be well washed, treated with vitriol and dried.

Spring disinfection should be done if perennial plants grow in the greenhouse. For this, substances for a specific culture are purchased. For soil using a solution of potassium permanganate. In the cold season should open a greenhouse. This will help to freeze late blight and prevent freezing of the structure.

Folk methods of late blight in the greenhouse: iodine, salt, ash

Popular methods of struggle have been tested since ancient times. With their periodic use, they are quite effective. Traditional methods have a significant advantage - they are absolutely safe for plants and soil.

Folk remedies to prevent late blight:

Phytophtorosis destruction by pharmaiodine is an effective method. Iodine is an excellent antiseptic. 20 drops of the drug diluted in 10 liters of water and sprayed the fruit.

Also, plants are treated with dairy products. Due to the lactic acid bacteria, the activity of the microorganism and the development of the disease are terminated. With water can dilute whey, kefir, low-fat milk. For greater efficiency, you can add iodine to them.

Soil for soil treatment can be used in its pure form

Saline solutions are used to process only green fruits.

Yeast perfectly inhibit the growth of late blight, so they are used in relation to water 100 g per 1 liter. Ash is used in its pure form for treating the soil before watering. You can also make a solution and spray the vegetables.

Also from late blight helps copper. A piece of wire must be threaded through the stem and wound around the culture. In some cases, garlic helps from the fungus. Prepare a solution with the addition of potassium permanganate and spray the plants.

How to get rid of late blight in the greenhouse: preventive methods

To control pests in a greenhouse is much easier than in open ground. In the greenhouse you can independently control the temperature and humidity. But why is it necessary to solve the problem, if you can prevent it. To do this, follow the simple guidelines.

Prevention of late blight:

  • Soil mulching
  • Timely weeding beds,
  • Cultures need to be tied up,
  • We need to get rid of excess sheets and stepsons.

Soil mulching and timely weeding of beds is an excellent prevention of late blight

For preventive measures should include the right neighborhood. And it's not just greenhouse planting. For example, when growing tomatoes near the greenhouse, it is necessary to exclude plantings in the garden of tomatoes and potatoes. At the end of the spring should be treated with phytosporin greenhouse. This chemical needs to treat the soil and the plants themselves.

It is necessary to carry out preventive measures in dry and calm weather.

Late blight appears in almost every greenhouse. It is necessary to carry out preventive measures in time. Subject to all the rules of the plant will not be able to hit any fungus.

Folk remedies for phytophtora (video)

Late blight is an insidious disease that even the polycarbonate coating cannot stop. Dome greenhouse or arched for fungus does not play a role. But there are a number of ways to help overcome the disease. In addition, in the fight against late blight, it is necessary to conduct regular greenhouse prevention.

Autumn efforts: how and what to process the greenhouse from the phytophthora

Many summer residents after harvesting in the fall close the greenhouse and for a while forget about it. Thereby leaving unmoved tops of the plants and soil on which the culture has grown on the overwintering and infected by the blight.

And then they wonder where the fungus came from in the new season, they panic and urgently look for what to treat the greenhouse from the phytophtoras. And the answer is simple: you just need to carry out autumn prevention before the onset of cold weather.

Late blight - the main enemy of the nightshade

Phytophthora or late blight is a fungal disease of plants. Its name comes from the Greek language and speaks for itself: φῠτόν– plant, φθαρτικός– destroying. It affects mainly Solanaceae, but can also develop on buckwheat or strawberries.

Tomatoes affected by blight

Manifested in the leaves of the plant in the form of a whitish plaque. Next, the ovaries are affected, the stem and the plant die. The fungus overwinters in the ground on infected tubers, roots or in the tops. Begins active development with the onset of spring. Warm, humid conditions are ideal for phytophtoras.

All plants in the greenhouse are affected at the same time therefore it is difficult for a person to recognize late blight at an early stage. With the development of the fungus, dark or black spots appear on the plant. On the fruits there is a softening of tissues and brown brown spots. Late blight is accompanied by bacterial rot. And if the plant did not destroy the fungus, then they will destroy the crop.

Preparing the greenhouse for overwintering

Modern polycarbonate greenhouses can not disassemble for the winter. Resistant to cold weather and precipitation material will allow the construction to stand more than one winter. At the end of October, after the end of the growing season and harvest, it’s time to start preparing the greenhouse for the next season. Before you begin processing, you must perform a series of preparatory activities.

In winter, the greenhouse must be completely clean of plant residues.

    Remove all additional materials. Stakes, twine, wire and other garter elements, tools, etc., are removed for further processing or disposal.

  • Remove soil from plant residues. It is in them that the phytophthora overwinter most often.
  • Remove the top layer of soil. It will be enough 7-10 cm. This will get rid not only of the fungus, but also of other pests.
  • To cultivate the land.

    Be sure to dig it, remove the pest larvae and sanitized.

  • Treat the greenhouse structures with warm soapy water inside and out.
  • Important! In preparing the greenhouse in any case, do not use hard metal brushes.

    To avoid damaging the greenhouse cover material, use only a soft cloth or sponge.

    Treatment and disinfection of soil in the greenhouse

    According to the rules of agronomy and planting technology, the soil needs to be changed in the greenhouse and greenhouse every 3-4 years. For this, a layer of 25-30 cm is removed and a new prepared soil is imported. But it is not always possible. To facilitate the task by removing only the top layer of 6-10 cm in which most often live pests and fungus.

    The soil must be disinfected: next year it will protect plants from bacteria and pests

    Then a deep digging of the soil (at least 20 cm) is carried out, and the soil removed from the beds, if it has been infected, is placed in a prepared pile in layers, pouring 180 g of lime into the prepared lime per 15 cm of soil. In the summer they loosen and mix. It will be possible to use this land again only in a year.

    Some gardeners are advised to handle greenhouse soil with boiling water or a fungicide. But do not forget that the soil contains a huge amount of micronutrients and organisms that are necessary for the full development of the planted culture. And these drugs simply devastate the earth.

    Mulch is useful not only in season, protecting plants from drying out and overheating, but also in autumn. After harvesting and preparing for the end of the season, it can be shallowly dug up. By spring, it will give a good organic layer.

    Grind the cleaned soil in the greenhouse

    In the fight against late blight, after harvesting tomatoes, eggplants or peppers, it will be good to sow the siderat plant (mustard, beans, lupine). This will help the soil to improve its health and be filled with organic matter

    Autumn processing greenhouses

    An excellent prophylactic against late blight will be carrying out the autumn treatment of the greenhouse. With its help you can get rid of unwanted organisms that have accumulated on the walls of the greenhouse during the past season.

    Film coating is processed as follows:

    • film is removed,
    • thoroughly washed with soapy water,
    • processed by blue vitriol,
    • dried,
    • stacks up until next season.

    The glass greenhouse or coated with polycarbonate is also washed with soap and dried. All metal and wooden frames are also subject to processing. Wood is trimmed and treated with quicklime, and the metal must be cleaned of rust and tinted.

    Both the internal and external surface of the greenhouse is subject to processing.

    Further processing is done in case of illness. To kill all pathogens and vectors of diseases, it is necessary to disinfect the premises. An excellent method in the fight against late blight is fumigating with sulfur. Use sulfur checker or cuttings sulfur.

    Tip! When disinfecting a greenhouse with sulfur, it is necessary to close all windows and doors tightly and seal the gaps. To achieve greater effect, the room is moistened with water from the inside.

    Sulfur consumption for fumigation is small. At 10 m3 of premises, 1 kg of sulfuric mixture is required. It is placed on a metal sheet and set on fire. To prevent fire, the sheet is placed in a water basin.

    Important! Observe safety precautions when fumigating a greenhouse. Wear a gas mask or respirator, protect your eyes with glasses, and your hands with gloves.

    Also processing is performed using sulfur bombs. They are much easier to use and have the same effect. They are also uniformly placed around the perimeter of the greenhouse and set on fire. The main disadvantage of sulfur fumigation is that if there is damage to the metal frame, corrosion will increase, therefore, treat all structures in advance or refrain from such a method of disinfection.

    Useful tips experienced gardeners

    In order to avoid “stepping on the same rake” during spring disembarkation and prevent phytophthora from re-propagation, use useful tips.

    Spraying greenhouses Bordeaux liquid

    1. If perennial plants grow in the greenhouse, the treatment should be carried out in the spring. Only products intended for these crops are used.
    2. An alternative to using sulfur bombs is spraying Bordeaux mixture.

  • To destroy the phytophtora remaining in the soil, it is necessary to treat it with a solution of manganese. Pre-digging to a depth of at least 20-25 cm.
  • At the end of autumn or in winter, you can open the doors and windows of a glass greenhouse and covered with polycarbonate.

    This can be done immediately 2 useful things:

    • to freeze all the surviving pests,
    • to exclude freezing of polycarbonate, achieving the absence of temperature difference.

    In winter, it is better to protect the greenhouse with a layer of snow.

    To improve the general condition of the greenhouse, prevent deformation of the polycarbonate and maintain its integrity, in conditions of increased snow load, it is necessary to strengthen the frame of the greenhouse.

    For this, additional arcs can be used, and T-shaped wooden supports can be installed indoors. They are installed on the entire height of the greenhouse, thus strengthening the frame. It is necessary 2-4 props, depending on the length of the greenhouse. With such props, your greenhouse will withstand any load, and you can sleep well all winter.

    When carrying out autumn processing of the greenhouse and preparing it for overwintering, you can avoid the recurrence of phytophthora and other dangerous diseases.

    The main thing is not to be lazy and carry out all the precautions, starting from digging up the soil, and ending with the processing of all additional tools.

    Remember: first you work for your greenhouse, and then it works for you. And this is repeated from year to year.

    Treatment of polycarbonate greenhouses in the spring from diseases and pests by phytosporin, sulfur checker, blue vitriol. Preparing a greenhouse in spring for planting seedlings, radishes, cucumbers

    Polycarbonate greenhouses in the spring need to be treated with special solutions. This will help protect the future crop from pests.

    Caring for a carbonate greenhouse should begin in the winter. Improper actions can cause serious problems for the integrity of the structure.

    • In winter, you need to clear the snow near the walls of the greenhouse, as well as from the roof structure.
    • If you do not want to see a broken greenhouse in spring, you will have to install supports from a vertical pole. One end of the pole should rest against the upper arc, and the second into the ground.
    • For the winter, the side vents and pistons are removed. At low temperatures, these parts may become unusable. If the vents are mounted in the roof of the frame, then it is necessary to make additional reinforcing elements to support the valves.
    • In the spring, you need to perform a series of actions, and what should be understood in more detail.

    How to clean a polycarbonate greenhouse in spring? Some tips:

    • Metal mesh, frame, fixtures and tools are treated with solutions from rust. If you do not have the factory tools on hand, use a mixture of lemon juice and vinegar, a little soda, diluted in water, carbonated sugary drinks, cut the potatoes in half. Rust with brass will help remove the mixture of 100 ml of vinegar, a pinch of salt and flour. The resulting gruel rub the metal, and then rinse with water. Rust with aluminum parts well cleaned with Alka-Seltzer.
    • If there is a heating system in your greenhouse, you will need to update the paint on the pipes.
    • A soap solution helps to get rid of dust and dirt.. After processing, you need to wash the entire frame with running water.
    • Polycarbonate plates are washed with soapy water. with the help of soft cotton napkins. Outside, you can wash the soap with water, and inside it is better to remove it with a damp cloth. Soap should not fall into the fertile soil.

    How to wash a greenhouse from polycarbonate?

    Important: It is forbidden to use window cleaner for washing carbonate plates. If you do not want to wash the greenhouse with soap, then it is better to wash the dust and dirt with water from a hose.

    Remember: Do not use scrapers, household chemicals with abrasive particles to clean a greenhouse.

    Disinfection and disinfection of the greenhouse in the spring

    Disinfection and disinfection of the greenhouse in the spring

    When the greenhouse is cleaned of dirt and dust, it is necessary to disinfect it. Copper sulfate with water will help from rot, scab, rust and late blight. If you basically do not use funds from stores, then you should pay attention to popular methods. Disinfection and disinfection of the greenhouse in the spring:

    • Broth needles. Half a bucket of rammed pine branches are poured with boiling water and infused. You can boil for 20 minutes and cool - it will be faster.
    • Nettle decoction. Half a bucket of dry nettle pour boiling water, let it brew, strain.
    • Pine extract from the pharmacy - 200 grams. Dilute this medium in a bucket of cold water.

    Wipe the polycarbonate sheets with any of these solutions. This will help get rid of various greenhouse diseases of fungal origin. If your greenhouse is infected with fungal diseases, and known methods do not help, then it is worth resorting to more powerful means.

    Polycarbonate greenhouse processing with phytosporin

    • Then dilute 1 tablespoon of the solution in 10 liters of water.
    • The resulting solution pour 2 square meters of soil.
    • Sprinkle over the wet earth with dry soil and cover with foil.
    • After a few days you can land.

    Interesting: Phytosporin treatment of polycarbonate greenhouse in spring is a proven pest control method. At the same time, beneficial microorganisms remain intact, which cannot be said when treating the soil with manganese or other similar means.

    Polycarbonate greenhouse processing with phytosporin

    Important: Wipe polycarbonate sheets from the inside with a sponge moistened with a solution of 2 tablespoons of any product with bleach to 5 liters of water.

    Many gardeners use phytosporin for processing polycarbonate. Make the same solution as for the soil, and wipe the walls and roof. Flush the solution is not necessary, the greenhouse will clean itself on its own using condensate.

    Processing of polycarbonate greenhouses in spring from phytophtoras

    Processing of polycarbonate greenhouses in spring from phytophtoras

    The causative agent of phytophthora is oomycetes. Scientists have long attributed these mycoorganisms to fungi, but recently they are distinguished in a separate group.

    Processing of polycarbonate greenhouses in spring from phytophthora:

    • Fitosporin-M, Radiance, Baikal EM - These are microbiological preparations that help to cope with the life cycle of a microorganism.
    • A solution of garlic and water. 40 grams of minced garlic pour a bucket of water and infuse for 24 hours. Plants are sprayed with this solutions, the inventory and walls of the greenhouse are washed.
    • Periodic pest control- steam room. This microorganism dies at temperatures above +30 degrees Celsius. Therefore, it is necessary to close the doors and windows in the greenhouse on a sunny day, and air well in the evening.

    Copper sulfate for greenhouse disinfection is used by many gardeners. This drug perfectly manifests itself from pathogens of powdery mildew, late blight, various rot, scab, curly and bacteriosis.

    Prepare a ten percent solution of copper sulfate, and wipe the walls and roof of the greenhouse with it. The greenhouse is treated with blue vitriol before planting. This will help protect vegetables and herbs from various microorganisms and bacteria.

    How to heat a polycarbonate greenhouse in spring?

    How to heat a polycarbonate greenhouse in spring?

    When choosing heating for the greenhouse, consider the features of the greenhouse, the goals when choosing a heater and personal preferences. How to heat a polycarbonate greenhouse in spring? There are several types of greenhouse heating:

    • Natural. Open all the windows and doors of the greenhouse on a sunny day. The sun's rays will warm the air and the earth inside the greenhouse. Such a heating system is simple. That this method worked, it is necessary to establish the greenhouse correctly. The sun's rays should fall directly into the room.
    • Artificial. The following technical methods are used for heating: a special device “wind power”, an electric heating cable, infrared heaters, heating with pipes, various furnaces.

    If the heating is not ready yet, and the street is getting colder, you can do emergency heating:

    • Wet the porous bricks with a combustible mixture and stack the barrel. Install this design near the greenhouse.
    • Mount the pipe from the top of the tank to the greenhouse ceiling.
    • Set fire to bricks.

    This design will quickly heat the room and will keep the required temperature until morning.

    Soil preparation in the greenhouse for cucumbers, radishes and for planting seedlings in spring

    Soil preparation in the greenhouse for cucumbers, radishes and for planting seedlings in spring

    Cucumbers and radishes grow well in warm soil. Even the seedlings will get acclimatized if the soil is prepared. In addition, the soil should be rich in mineral fertilizers and organic matter. Soil preparation in the greenhouse for cucumbers, radishes and for planting seedlings in spring consists of the following stages:

    • Remove the top layer of soil and add manure (30-40 cm).
    • Make deep holes at a distance of about 1 meter and pour in a bucket of hot water. Manure will generate heat.
    • In a few days the temperature of the air and soil will be established in the greenhouse.favorable for planting cucumbers, radishes and seedlings.
    • Before planting, pour a layer of fertile mixture: turf ground, humus, clean fine sand or sawdust (2: 2: 1).
    • Pour this mixture and smooth well..
    • Disinfect the soil with phytosporinas described above.

    • Peat, sawdust and mullein (3: 1: 0.5).
    • Ammonium nitrate, superphosphate, potassium chloride.
    • Phosphorus, potassium.
    • Bird droppings: Dissolve 1 matchbox litter in 10 liters of water. Allow the solution to infuse for 12-24 hours, and then pour the soil.

    If you do not have any of the necessary components, you can get already finished land. Many companies manufacture soil based on the upper fertile layer. It will be an excellent base that can be improved to grow a rich harvest in your greenhouse.

    How and what to process the greenhouse from phytophtora in the fall

    Processing the greenhouse from polycarbonate in the fall from phytophthora is a prerequisite for getting rid of this disease, as well as a means of prevention and a guarantee of a good harvest next year.

    What is phytophthora and how is it dangerous for plants and humans? How to treat the greenhouse from phytophtora in the fall and during the growing season of plants, traditional and modern means of combating the disease. Methods of processing plants and how to disinfect the ground in the greenhouse from the phytophthora? You will find answers to these and some other questions that interest summer people so much in this article.

    What is phytophthora?

    Phytophthora or late blight is a plant disease caused by the fungus Phytophthora infestans. This name translates as “destroying plants”, which rather accurately characterizes the consequences of its infection.

    The main signs of late blight infection are brown spots on the stems, leaves and fruits.

    Plants of the family Solanaceae are mainly affected: potatoes and tomatoes, but cases of infection of strawberries, strawberries, etc. are often known.

    The defeat of the fruit of the blight

    The first signs of infection can be seen at a site approximately in the middle of summer, or if it was hot and rainy, it is closer to autumn. It is then that the weather conditions are most favorable for the spread of the fungus:

    • Constant high air humidity of about 75%
    • Weather with warm moderate temperature 15-200C,
    • Significant fluctuations in day and night temperatures
    • Abundant dew.

    Important! One of the main reasons for the rapid spread of the disease in the open field is planting tomatoes next to potatoes, eggplants or Physalis, and for greenhouses thickening of the rows or overgrowing them with weeds, which reduces the possibility of ventilation.

    Methods for transmitting spores of phytophthora can be different, but most of the infection occurs through the soil, seeds and seedlings. Equally different ways to combat and prevent disease.

    Phytophthora development cycle

    Prevention of phytophthora

    Any disease is easier, and most importantly cheaper to prevent than to cure. This statement holds true for phytophtoras. There are several simple prevention methods that can reduce the risk of disease and increase yields:

    • The use of resistant varieties, the use of healthy planting material. The use of your own seeds collected on the site affected by blight, is strictly prohibited,
    • Fertilizing plants should be made with phosphate-potassium chlorine-free fertilizers:
      • potash,
      • wood ash,
      • potassium sulfate.
    • It is necessary to observe crop rotation - it is impossible to sow in one place close cultures for many years.
    • Use modern hybrids with a maturity of 85-90 days.

    How to get rid of phytophthora in the greenhouse with the help of natural remedies? Good indicators give biologically active and environmentally friendly drugs that increase the resistance (immunity) of plants to various diseases. For greenhouses, the following anti-phytophthora remedies are suitable: Kresacin, Novosil, Immunocytophyte, Biosil.

    How to clean the greenhouse from phytophthora without using chemical and biologically active substances? Not bad helps "steaming" greenhouses. On a sunny hot day before watering, you must close all doors and windows.

    When the temperature in the greenhouse reaches 30-35 ° C, we wait a few hours, then we air the structure well. At 30 ° C, the disease stops the spread, at 35 ° C, the spores begin to die.

    Before starting a session, it is necessary to get rid of all infected plants in the greenhouse or their affected parts.

    Good results are also shown by plant growth stimulants, which have a positive effect on their immunity. Disease resistance is significantly increased by watering the greenhouse with Oxy-humate, 10 ml per 1 l of water and Ekosil 1 ml per 3 l of water.

    How to process a greenhouse after phytophthora, if you do not want to use biologically active stimulants? You can use traditional and proven "Bordeaux" liquid. It does not penetrate the inside of the plant and therefore processing can be carried out almost every week.

    Biological treatment of the greenhouse from phytophtoras in the fall, if the site was critically infected, consists in planting white mustard in the affected area for one season. In combination with the treatment of soil with lime, this will help to completely overcome the disease.

    In the years of mass distribution or when planting plants on contaminated land, the use of immunostimulatory drugs is ineffective. Their use is recommended only in combination with fungicides.

    This not only provides greater efficiency in the fight against diseases, but also reduces the pesticidal load on plants and the soil. Disinfection of the greenhouse from phytophthora can be performed by several types of fungicides.

    Depending on the choice of their type is determined by the processing time.


    They are used for prophylaxis and during the period of fruit formation, when chemical preparations can no longer be used. These include Fitosporin M, Alirin B, Hamir, Baksis, Planriz. Can be used for disinfection and treatment of polycarbonate greenhouses in the fall from phytophthora, as a preventive measure when planting winter crops and seed material.


    The active substance is copper oxychloride. The principle of action - preventing the penetration of spore fungus into the plant tissue. Processing is done in advance, at the beginning of the vegetative period.

    Since copper oxychloride is not absorbed by the plant and is not spread through it, the entire growth after spraying will remain unprotected, so the treatment must be carried out as carefully as possible.

    Contact preparations include HOM, Abiga-Pik.

    Contact and system

    Processing is performed immediately after the discovery of the first traces of late blight in the greenhouse. The systemic drugs that make up the mixtures are absorbed by the plant and spread along its periphery, while the contact ones, prevent the possibility of reinfection. Contact systemic drugs include: Ordan, Profit Gold, Kurzat R, Thanos.

    Stems affected by blight

    Frequency and time of processing

    How to process greenhouse from phytophthora during the growing season? The number of plants sprayed in the greenhouse with fumigators depends on the weather. In cloudy and rainy summer, stimulants are applied and sprayed up to 4-5 times at intervals of up to 10 days. However, it should be remembered that the last treatment should be no later than 20 days before the harvest.

    The first sprays are produced by contact preparations with the addition of immunostimulating substances, then by contact system at intervals of 8-12 days, but not more than 4 disinfectants per season.

    Processing greenhouses in the autumn

    Before treating the greenhouse from phytophthora in the fall, it is necessary to completely clean the structure of all plants and their residues. Effective processing of supporting structures and polycarbonate of the greenhouse and soil itself can help to get rid of the infection.

    How to deal with late blight in the greenhouse in the fall, if all the means used in the summer could not neutralize the disease? It requires an integrated approach.Spray bleach at a rate of 400 grams of lime per 10 liters of water (infused for 3-4 hours). All constructions and soil are treated.

    The resulting sediment is used for coating wooden parts and structures of the greenhouse.

    Effective autumn processing of greenhouses from phytophtoras - fumigating with sulfur. You can use special checkers purchased in the store, and you can place sulfur on small braziers with coals in different parts of the greenhouse. Enough 50-80 th on 1 m3 of space. Leave the room closed for 1-2 days, then air out.

    A very effective, but unsafe way is spraying with formalin. 250 gr. 40% solution per 10 liters of water. However, due to the fact that formaldehydes are released into the air, care should be taken in a gas mask.

    Phytophthora in the greenhouse, what to do in the fall, spring and summer, recommendations of the experienced gardener on the video:


    There are many popular methods than to process the greenhouse for the winter from the phytophthora. One of the most effective, but laborious, is the replacement and subsequent processing of the land in the greenhouse infected taytora. This method is used in conjunction with cleaning and disinfecting structures.

    How to disinfect the ground in the greenhouse from the phytophtoras for its further safe use? To do this, the soil is stored in piles, pouring every 20 cm layer of lime. The following year, it is mixed with manure to fertilize and restore the acid balance of the land. Alternating the land from the greenhouse and the collar a year later, it is possible not only to destroy the disease, but also to obtain excellent yields.

    Signs of phytophthora appearance in the greenhouse

    Phytophthora is a dangerous disease that affects many cultivated plants, most often solanaceous. Care for the greenhouse in the fall after late blight requires serious efforts to prevent serious complications for the future harvest. After harvesting, spores of phytophthora are stored in the upper parts of the soil, where they can successfully survive the winter season until the next season. The first signs of this fungal disease are the appearance of brown spots on the leaves of cultivated plants, as well as white bloom at high humidity indoors.

    If you do not fight the disease, then phytophthora can fully harvest tomato, potato and many other plants. Therefore, the processing of the greenhouse after phytophthora in the fall is very important to destroy all disputes that exist in an enclosed space, as well as on its structure and in the soil.

    What is dangerous this disease

    The fungus phytophthora eventually spreads to the entire crop. Leaves gradually turn brown, dry and curl. If the gardener is going to save the crop, he often removes green tomatoes from the bush and lays them on ripening. In fact, this does not help, because the tomatoes in the box are also infected with the fungus, like other fruits. If you do not process the space in the fall, then the next crop will also spread the mycelium of the fungus and the yield will drop significantly, up to complete destruction.

    How to process a greenhouse after phytophtoras in the autumn

    Preparation for the new season occurs immediately after harvest. You can handle special chemicals, as well as biological agents and temperature regimes. You can use both the proposed tools separately, and apply a complex effect. Soil treatment from phytophtoras in the fall in the greenhouse is necessary in the form of a whole series of measures both to combat and to prevent the disease.

    How to deal with blight in the greenhouse in the fall with chemicals

    First of all, it is necessary to properly prepare the enclosed space after harvesting. Only after preparation can you use chemicals to fight the fungus. For chemical processing should be used:

    • hydrated lime,
    • bleach
    • concentrated solution of blue vitriol,
    • sulfur checkers
    • chemical fungicide.

    Each of the presented preparations is recommended to be used correctly in order to process the greenhouse for the winter from phytophthora:

    1. Sulfur fumigation. Conducted special checkers "Climate", "Fas", as well as "Volcano". Described in detail in the instructions how to use these checkers.
    2. Copper sulphate is required to be diluted in the ratio of 100–150 grams per 10 l of water. Then with the composition, whiten all the places where pathogenic microflora is observed and there is a danger of infection.
    3. Slaked lime. Mix 4 kg of freshly lime with 0.5 kg of copper sulphate and 10 liters of water. To whiten the entire greenhouse, including brickwork and all places where pathogenic flora can form.
    4. Bleaching powder. A solution is made of 1 kg of dry matter per 10 liters of water. Insist for an hour and spray the entire room.

    In addition to all known solutions, various universal fungicides are successfully used. They are used strictly according to the instructions that are attached to the fungicide for sale. The most common method is tillage in the greenhouse in the fall with phytosporin.

    How to treat the greenhouse after phytophthora in autumn with biological preparations

    Biological fungicides can be used to treat small spaces. These drugs are based on the natural ability to suppress pathogens. But these drugs have their own condition - they only work at a temperature of 12-14 ° C above zero.

    The following drugs are most commonly used:

    The treatment consists in dissolving the preparation, according to the instructions, the whole room is sprayed with water and this solution. After 14 days, spraying is repeated.

    Temperature control method of late blight in the greenhouse

    Like many other species, the phytophtora fungus can live only in strictly defined temperature regimes. Therefore, to get rid of the pathogenic microflora, it is necessary to radically change the temperature regime in the greenhouse.

    After harvesting at the onset of frosts and cold weather, it is recommended to clear the greenhouse from spores by freezing. To do this, it is necessary to open the greenhouse space for several days at the lowest possible temperatures. If snow falls, it is recommended to remove it from the surface of the soil, since zoospores can survive under a layer of snow and become more active in the spring.

    As well as pathogenic microflora does not tolerate well and temperatures above 35 ° C. In the autumn of such a temperature for the greenhouse does not create, and therefore good to handle it with boiling water.

    How to get rid of phytophthora in the greenhouse in autumn: a set of measures

    In order to protect their harvest in the next year in full, experts recommend treating the greenhouse until the fall with a set of measures. First of all, after harvesting, prepare the soil. First you need to remove all the tops, old foliage, as well as broken structures, remnants of twine, which tied up the plants.

    After that, depending on the material from which the room is made, disinfection is carried out. Sulfur drafts, hydrated lime and other disinfection methods can be used.

    It does not hurt to treat the greenhouse with phytosporin in the fall, especially if the infection was large-scale.

    Caring for a greenhouse in the fall after late blight is excellent if you add store fungicides to the ground, but you should strictly follow the instructions and all the proportions so as not to harm the person. All spraying procedures should be carried out in a respiratory mask to prevent toxic chemicals from entering the respiratory tract.

    Preventive measures against phytophtoras in the greenhouse

    There are a few rules, following which it is possible to avoid infection with the latent crop in the greenhouse:

    • you should not plant cultivated plants too thick
    • It is recommended to mulch the soil,
    • bushes must be tied up without fail
    • clean stepchildren and extra leaves.

    With the observance of all the necessary preventive measures, as well as with the creation of the correct microclimate, the gardener will be able to avoid the appearance of pathology and crop damage.


    To process a greenhouse from phytophtoras in the fall is an important and necessary exercise, especially if there are signs of contamination in the greenhouse this season. Processing can be carried out with the help of chemicals, biological fungicides, as well as temperature regimes. The processing of the greenhouse from phytophthora in the fall is well shown in the video, so even a novice gardener can handle it.

    Polycarbonate greenhouse processing in autumn

    The greenhouse of polycarbonate has become an excellent assistant in the cultivation of vegetables, because thanks to it, it is possible to reap a crop, to do it very early, at a time when on the open ground the fruit ripening has just begun. When purchasing such a greenhouse, you need to remember that care must be taken not only for seedlings grown inside, but also for the structure itself.

    Stages of work

    If you want to get a quality crop in the next season, in the fall be sure to carry out the treatment both within the structure itself and in the soil.

    The whole complex of works can be divided into several stages:

    • cleaning and tillage
    • wall and frame treatment
    • frame reinforcement
    • soil protection and fertilization
    • disinfection: species.

    Cleaning and tillage

    Photo 1 Cleaning and soil treatment in the greenhouse

    First of all, remove all plant residues and weeds from the bed. Be sure to dig and shake the soil in order to get rid of the roots. If we are talking about such a weed as wheat grass, try to remove even small particles of the roots, otherwise this spring will actively grow in the spring.

    Be sure to collect all the larvae - only some of them will die when digging the soil, and in most cases it is only a bear.

    For example, the larvae of the cockchafer do not die at all under any circumstances in the ground - neither digging nor freezing is terrible for them.

    There are cases when even boiling water treatment did not damage the wireworm or Maybot larvae. Ideally, it is necessary to sift the upper layer of the soil and collect all the larvae with their hands, then burn them.

    Wall and frame treatment

    Photo 2 We clean and process the walls and frame of the greenhouse

    To begin, conduct an inspection of polycarbonate, especially of the joints - no matter how good the fit is, between the seams there can still be particles of grass or foliage, on which microorganisms will further develop. Get rid of all unnecessary help ordinary household vacuum cleaner.

    If you notice parasites or rot spots on the greenhouse walls, then you need to do the processing, for example, using the following means:

    • sulfur bombs - plug all the cracks and set fire to the boll; you can open a greenhouse after 2 days.
    • Bordeaux liquid - it sprayed the walls of the greenhouse.

    If time permits, thoroughly wash the entire structure from inside and outside. For this purpose, suitable concentrated solution of household soap - 2 liters of water 1 piece, grated on a fine grater. Let the solution stand for at least 30-60 minutes so that the soap is completely dissolved.

    A very good tool is the treatment of bleach, but after it remains stains on the walls.

    Preparing the greenhouse for wintering

    If there is enough space, the removed soil should be poured into a stack in layers, pouring each layer of bleach. For the calculation of the formula is used: for every 15 cm of soil 180 g of lime. Leave it in this form. In the summer this soil will need to be mixed and left until next spring. Only after such procedures can it be used again.

    We dig up the remaining soil, remove the larvae, insects, parts of the root system of plants. Leave it in a well-loosened form.

    After that it is necessary to fumigate the greenhouse with sulfur.Cover all the gaps so that there is no air exchange with the external environment in the greenhouse.

    It is better to buy a ready-made sulfur bomb, there all proportions are properly maintained. Place it approximately in the center, light it and tightly close the door to the greenhouse. In this form, all you need to leave 5 days.

    The processing of the polycarbonate greenhouse in the fall does not end with the phytophtora. After fumigation, it is necessary to air it properly. It is worth remembering that when entering into a chemical reaction with air, sulfur vapors turn into sulfuric acid.

    It settles on the walls of the greenhouse and damages metal parts. Therefore, it is necessary to pre-treat them with an anti-corrosion compound.

    Processing from phytophthora polycarbonate greenhouses

    Phytophthora is a scary word for agronomists, gardeners and gardeners. This is a very dangerous disease affecting the nightshade and some other cultivated plants, such as strawberries or cucumbers. As a rule, plants infected with late blight are not treatable, the only way out is to destroy them.

    Late blight: danger of fungal disease

    Phytophthora is a fungal disease affecting plants even in a polycarbonate greenhouse. Just like any fungus, a late blight spore consists of mycelium, conidia, and sporangia. The appearance of the mycelium resembles a white spider web. As a rule, it lives and develops in plant tissues. The reproduction of fungi is carried out with the help of spores formed in sporangia. After the spore has matured, the sporangia shell breaks, releasing the spores out. After that, they spread along with water, falling on plants, where the new life cycle of phytophthora begins. Spores of phytophtora are not afraid of even severe frosts. The active development of the dispute begins after the temperature rises to 10 degrees Celsius. The first sign of late blight is the appearance of brown spots on the stems and leaves of plants. At high humidity, the inner part of the leaves is covered with white bloom. Young tubers of potatoes and tomatoes, affected by late blight, become covered with dark indented spots, and the skin becomes fragile. It is through the skin that the plant becomes even more infected, at the same time spreading the disease to neighboring plants. If timely processing of tomatoes from phytophtora is not performed, the fruit tissues quickly rot and decompose, giving off a rather unpleasant smell.

    Often, gardeners in an attempt to at least partially save the crop, tearing off the green fruit and hiding them for ripening. But along with the infected fruits, the phytophtora fungi fall into the box and after a while hit all the other fruits.

    How to process greenhouse from phytophthora

    Preparation for the new planting season is made in the autumn, immediately after harvest. In the greenhouse, especially from polycarbonate, the likelihood that the spores of the phytophthora will persist in the upper soil layer, on plant residues or greenhouse construction elements, is very high. Therefore, when growing plants in greenhouse conditions, it is imperative to carry out processing from phytophthora. In this case, you will not think about how to save tomatoes from phytophtoras, but where to put the entire harvest.

    Thorough disinfection of the greenhouse will allow to destroy the phytophthora disputes, as well as prevent the occurrence of the disease in the future. It is conditionally possible to separate the processing means from the phytophtora on

    • biological,
    • chemical,
    • temperature.
    The structural elements of the greenhouse can be processed by chemical means. Chemical and temperature methods are suitable for disinfecting the soil. Biological agents allow preventive measures to be taken.

    Cleaning greenhouses from plant residues and additional materials

    Before disinfecting the soil from phytophthora chemicals, it is necessary to clean it from plant residues: tops, missing fruits, roots and weeds.

    You also need to clean the greenhouse from the old twine and trellis.

    Even if the plants did not hurt, due to the high concentration of plantings, they still left a large number of different pathogens. That is why the processing of polycarbonate greenhouses must necessarily be accompanied by the burning of all residues of plants and other materials. If you do not do this, then after winter all the microbes become more active and will begin to infect young plants.

    Greenhouse Disinfection and Treatment

    Processing greenhouses from phytophthora allows you to save plants and get a good harvest. The greenhouse can be made of glazed window frames, polycarbonate, or from conventional film. Before proceeding with gas disinfection, it is necessary to check the tightness of the greenhouse design and cover all the gaps. All disinfection works are carried out at a temperature not lower than 10 degrees Celsius. When disinfecting, the greenhouse is fumigated with sulfur or lump sulfur checkers. The average dosage is 50-80 g of sulfur per cubic meter; when infected with a spider mite, the dose increases to 150 g. In order to increase the toxicity of the fungicide, it is recommended to spray all the greenhouse surfaces with water beforehand. Processing of the greenhouse from polycarbonate in the spring from phytophtoras is carried out necessarily in a respirator or in a gas mask. The greenhouse needs to be fumigated with the gray burning on the trays, which are placed along the perimeter of the structure. After sulfur lights up, the greenhouse closes tightly for three days. After this period, the greenhouse must be thoroughly aired.

    Unfortunately, this method is not suitable for metal greenhouses, because sulfur pretty quickly eats away a protective layer of metal. Therefore, in such greenhouses resort to wet disinfection. The essence of this procedure lies in the abundant spraying of a solution of bleach on all surfaces of the greenhouse, including the soil. To prepare the solution, 400 g of lime should be diluted in a bucket of water and let it brew for 4 hours. You can also use a solution of copper sulfate (75 g of the substance diluted in a bucket of water).

    Before processing the greenhouse in the spring from the phytophthora, especially if its frame is made of wood, it is necessary to wipe the structural elements a solution of fresh lime with the addition of vitriol. This will protect the tree and add light to the greenhouse. Also, along with chemical treatment, you need to destroy all the moss and lichens that have grown over the summer on the frame of the greenhouse.

    After the disinfection is carried out, it is necessary to thoroughly wash all glass surfaces of the greenhouse. To do this, a weak solution of any kitchen cleaner that is applied to the surface with a sprayer is suitable. After that, it remains only to wipe the glass with a nylon brush and rinse it with clean water.

    Soil treatment in the greenhouse

    Upon completion of disinfection procedures, care must be taken of how to treat the land after the phytophthora. It is necessary to thoroughly dig up the top layer of soil and be sure to fertilize it with humus, peat, manure, based on the calculation of half a bucket per square meter.

    If you do not know how to treat tomatoes from phytophthora, then for complex protection it will be suitable sand ash mix, which fall asleep beds. Also for the disinfection of the soil, you can use an aqueous solution of the fumigant "Carbation". It is recommended to use when digging the soil, when the temperature of the soil is 10 degrees Celsius.

    Winter airing greenhouses

    Winter is a serious test for plants, because low temperatures can be very harmful for future crops. Winter airing of the greenhouse plays a large role in the question of how to properly protect tomatoes from phytophtoras. Of course, if the greenhouse is heated in winter, then you can not worry about negative temperatures.

    But heat for plants is not everything.Plants should breathe, but, as a rule, in the fall the greenhouse is very tightly “plugged” to minimize the effects of low temperatures. As a result, the oxygen level becomes minimal. The only way out is the organization of ventilation, thanks to which oxygen will be supplied in sufficient quantity to the greenhouse.

    When wintering the greenhouse, it should be assumed that at least 20% of the greenhouse is ventilated.

    If this is ignored, then inside the greenhouse will stagnate moist air, which is an ideal environment for the development of late blight.

    How to cure phytophthora of tomatoes in the greenhouse

    The question of when and how to process tomatoes from phytophtoras depends on many factors: the size of the greenhouse, the type of vegetable crop, the season and so on. Remember the main thing - you should not often use products containing copper, because it can be deposited in the ripening crop. Instead, it’s better to resort to popular methods, among which:

    • Garlic infusion. This tool is extremely well established among experienced gardeners. To make it, you need to grind one and a half cups of peeled garlic, add half a teaspoon of potassium permanganate and pour two liters of water. After that, you need to cover with a lid and let it brew for 30 minutes, and then dilute with 10 liters of water. Consumption is based on the calculation of 0.5 liters of garlic solution for each bush.
    • Water with iodine. Iodine from phytophthora in the greenhouse has a disinfecting effect on plants. To prepare a solution, dilute 10 ml of ordinary 5% iodine in a bucket of water. Before use, remove all yellowed leaves and leaves with dark spots. Spray the bushes and fruits with this solution, and after 3 days the procedure is recommended to be repeated.
    • Serum or milk solution. Dilute 100 ml of milk in one liter of water, then spray the tomatoes with this solution. Also, milk can be replaced by kefir. Lactic acid bacteria contained in dairy products do not allow phytophthora to develop. To enhance the effect in the milk solution, you can add a few drops of iodine. Spraying with this solution protects against phytophthora, and also fertilizes the soil and plants. The interval between spraying should be 2 weeks. If the phytophthora appeared on tomatoes in the greenhouse and you do not know how to deal with it, then try sprinkling the plants with a solution of serum. It is diluted with water in a ratio of 1 to 1 and has the same effect as the milk solution. Plants are treated with this solution throughout the summer period.

  • Salt solution. It is necessary to take regular table salt and dilute one cup in proportion to a bucket of water. This solution protects plants from various diseases, and after drying forms a protective film on the fruit.
  • Phytophthora in the greenhouse: preventive actions

    Plants grown in greenhouse conditions have the advantage of protecting against phytophthora compared to plants grown in open ground. In the greenhouse creates its own microclimate, which can be adjusted regardless of whether it is cold or damp outside. In order for you not to wonder how to save tomatoes from phytophthora in the greenhouse, follow simple rules for the prevention of late blight:

    • mulch the soil
    • do not thicken the landing,
    • tie up bushes
    • Carefully pick off stepchildren and extra leaves.
    In addition, to protect tomatoes in greenhouse conditions, do not plant tomatoes and potatoes in the open field next to the greenhouse to prevent spylophytes from falling into the greenhouse. Phytosporin treatment of the greenhouse in spring is carried out at the end of June. Spray the tomatoes with this biological product, and also constantly treat them with the soil under the tomatoes.

    Complex of measures

    Preparation of the greenhouse in the fall should take place at an air temperature of + 10-15 o C, in dry weather.Competent construction prevention, quality soil care in the greenhouse in autumn is carried out in several stages:

    • cleaning,
    • spring-cleaning,
    • disinfection of surfaces
    • repair facilities
    • cultivation of land in the greenhouse in the fall: introduction of chemicals — fertilizers, preparations for pests and infections, top dressing, improvement of the soil structure, digging or replacing the fertile layer,
    • fortification,
    • insulation, lighting, heating (if necessary).

    The video shows step by step the process of how the autumn processing of polycarbonate greenhouses is carried out, preparations for washing the structure are recommended in the video.

    Cleaning and washing designs in the fall

    Treatment of the greenhouse in the fall of pests and diseases begins with cleaning the premises. You should take out inventory, trellis, remove tops, roots, dig up the soil, remove plant residues. Through a hose with a spray to wash the dirt from the surfaces. Wash the walls and ceiling with a warm, soapy solution with a cloth or sponge. Strongly alkaline household preparations, abrasive pastes are not recommended, they can damage the reflective characteristics of the covering material. To clean the slots, knots, mates with a household brush or a toothbrush with a bristle of medium hardness. Rinse the greenhouse with clean water, wipe with a dry cloth, open the doors, air vents, dry the room.

    In order to avoid the manifestation of corrosion, the fungi frame should be treated with a composition prepared from bleach. Disinfection solution is prepared according to the recipe: lime 2 kg per 10 liters of water + 100 g of copper sulfate. Apply the composition is better with a bast or a soft brush. You can buy a ready-made mixture of components in the store, called Bordeaux liquid.

    Film, glass coating is sufficient to wash with soapy water, rinse, dry. The film is recommended for the winter to remove, in order to extend its life. Processing a greenhouse made of polycarbonate in the fall requires additional disinfection measures: the coating should be wiped with manganese solution.

    After cleaning the joints are checked, if there are gaps, they should be sealed with a sealant. Damaged pieces of covering material are being replaced. Doors, vents must fit snugly to the frame - a prerequisite that will help avoid icing structures in the winter.

    Important: If there are deep scratches on the metal base, before processing the greenhouse in autumn, the defects should be cleaned with abrasive, degreased, covered with primer and paint.

    Galvanized, unpainted metal elements are recommended to be treated with a 9% solution of vinegar. It is better to wash the parts made of wood with signs of fungus with bleach; after drying, lubricate with copper sulfate solution. Protect the wooden frame in the fall will help whitewashing a thick solution of slaked lime.

    A wooden structure after cleaning and washing in the autumn is recommended to fumigate with sulfur blocks, 100 g per 1 m 3 volume. Processing is carried out in a sealed room, checkers are placed on metal racks, pallets, evenly distributed over the entire area, set on fire, the door closes. The procedure lasts 3 days, after which the greenhouse is ventilated. If the metal frame, the procedure of fumigation with sulfur checkers is prohibited, it will lead to blackening of the metal, as a result - corrosion.

    We offer a video that tells you how to properly fumigate a greenhouse in the autumn with a smoke sulfur bomb.

    Caring for a polycarbonate greenhouse in the autumn - than to wash

    Disinfection of polycarbonate greenhouses in the fall is done with copper sulfate solution. If during the season there were no pests, then 75 g of copper sulfate on a bucket of water is enough to moisten rags and wipe the frame, walls, and ceiling.

    The question is topical: how to wash a polycarbonate greenhouse in the fall, infected with spider mites and other pests. In cases of diseases and infections, surfaces are treated with a more saturated solution of copper sulphate, prescription: 200 g of vitriol per 10 liters of water.The surface is washed for 2 times.

    Copper sulfate - the best recommendation than to process a polycarbonate greenhouse in autumn

    How to prepare the soil in the greenhouse in the fall

    According to the reviews of experienced gardeners, it is recommended to take out the ground from the greenhouse, fold it into a place encircled at the site, with a layer of 200 mm, pour it with bleach, dig it out, and leave it freezing for the winter. If you plan to bring a new soil, then the old land can be evenly scattered around the garden.

    When there is no possibility to completely replace the soil in the greenhouse, it should be disinfected, fed, improved. The cultivation of land in the greenhouse in the fall begins with the cleaning of the beds from vegetable garbage. Then sprinkle dry bleach, consumption per 1 m 2 of about 100 g, after which the beds are dug up.

    In the event of a strong infection of the greenhouse with infections, if the plants were often sick, were destroyed by harmful insects, in the fall the ground should be etched with 2.5% formalin solution. The way unsafe, but effective, helps to destroy even the larvae, insect eggs. The substance is very harmful, so before treating the soil in the greenhouse in the fall with formalin, wear gloves and a respirator. Pour solution into pulvilizator, spray 1 l of formalin per 1 m 2 of beds.

    When the chemical treatment of the soil in the greenhouse is completed in the autumn, the room is closed, left for 5-10 days to maximize the impact of the drugs on pests and disease-causing infections. Next, air, fertilize the soil, feed, improve its structure:

    • pour a layer of ash
    • fertilizers are added, the type depends on agricultural crops,
    • carefully watered with a solution of potassium permanganate,
    • clean sand, peat, compost are scattered from above, you can fertilize with sawdust, manure,
    • The beds in the fall are dug up to the depth of a shovel, the soil is properly loosened, the remaining roots are selected.

    Further cultivation of land in a polycarbonate greenhouse in the fall depends on the diseases it suffered during the season.

    Attention: Adding compost, manure, peat to the soil can infect the greenhouse with phytophthora. To avoid ailment, it is recommended to use Stubble Biodestructor, it works well in conjunction with nitrate and sawdust.

    Processing of the greenhouse in the fall should take place at a temperature of + 10-15 ° C in a protective suit

    Biological products for tillage in the fall

    In addition to chemicals, which often have side effects, the introduction of biopreparations into the soil in the autumn gives extremely positive results and helps to significantly increase fertility:

    • fix nitrogen
    • bind heavy metals
    • help in the breakdown of pesticide residues,
    • activate natural growth hormones
    • multiply the effect of chemicals.

    What to fertilize the land in the greenhouse in autumn, per 100 m 2 area:

    • phytocide - 300 ml,
    • Bitoxibacillin - 100-150 ml
    • Lepidocid - 30 ml per bucket of water.

    Phytocide is a powerful biofungicide, has a wide spectrum of action. Used for seed treatment, plant disinfection of soil in greenhouses. The drug can be used in 2 ways:

    • First, the land is treated with a fungicide; a phytocide is used in the vegetable growing season.
    • In the fall, a phytocide is added according to the instructions indicated on the manufacturer’s pack, if plant diseases appear during the season, chemicals are added for processing. With this variant of chemical preparations much less is applied, which favorably affects the ecological safety of the crop.

    Bitoxibacillin, lepidocid - insecticides of biological nature. Bitoxibacillin is used to kill the beetles, lepidocid fights against the larvae and their caterpillars: moths, butterflies.

    Please note: Treatment of beds in the fall in a greenhouse with a biological substance with a nitrogen facet increases soil fertility. Bring it into the ground, to a depth of 50-100 mm, based on 1 m2 - 10 g of the drug.The treatment with azatofittom of the earth in the fall improves seed germination, seedlings take root better, stimulates the development and strengthening of the root system, and the agriculture becomes resistant to diseases.

    An effective novelty is considered to be the biological complex of BTU, a universal preparation that provides fungicidal protection. In the autumn, it is recommended to bring it into the soil to protect the future crop from bacterial diseases and fungi, to restore the beneficial microflora of the soil. Treatment of soil BTU in the fall to increase the survival rate of seedlings, increase seed germination. Its use reduces many times, and in some cases even eliminates the use of mineral-based fertilizers, BTU mobilizes potassium and fluoride in the soil.

    Treatment with biological products in the fall is safe for plants, effectively coping with greenhouse diseases, contributes to a bountiful harvest

    Ants and aphids - do not spill water

    In addition to the whitefly, spider mite greenhouse often affects aphids, ants, these pests always take root in tandem. The best way to get rid of them is to process the greenhouse with sulfur checkers in the fall. Since disinfection of a polycarbonate greenhouse in the fall on a metal frame with fumigation is not possible, spraying the soil and surfaces with Bordeaux liquid, which is a protective fungicide, bactericide and pesticide, will help.

    Good to know: Treating a polycarbonate greenhouse in the fall with copper sulfate is considered the safest, most effective way to control pests and infections in buildings of this type.

    With a strong infection will help additional processing of the greenhouse from polycarbonate in the autumn of the following substances:

    • Spraying of surfaces and soil with infusion of ash, tobacco - on a bucket of water 200 g, insist day.
    • Shed soil, and the surface can be washed with a solution obtained from finely chopped potato tops, you will need 2 kg per 10 liters of water.
    • No less useful way to process a polycarbonate structure with a decoction of tomato tops in a bucket of water, for maximum efficiency of the solution tops boil for 30 minutes, then filter.

    The video below describes in detail how to get rid of the whitefly in the greenhouse in the fall.

    How to disinfect a greenhouse made of polycarbonate in the fall from keel, halon-numbness, black leg

    To get rid of the keel in the greenhouse will help the treatment of the soil with a 40% solution of the carbathion. According to the instructions, 500 g of the substance is diluted in a bucket of water and, after digging, spill the soil thoroughly.

    If the plants were struck with a black leg, a gallon dumbness, then working out carbofos will help get rid of these ailments. The solution can be prepared according to the recipe: powder 90 g per 10 l of water. The soil is shed before digging, left for several days, then dug, so the substance penetrates into the deep layers of the soil.

    How to process greenhouse from phytophtoras in the fall

    Bringing phytophtora from the greenhouse is very difficult, the spores of the fungus are very tenacious. After removal and burning of plant residues, it is recommended to shed the soil with boiling water, close with dense polyethylene, and let stand. Then the earth is poured over blue vitriol, sprinkled with dry lime, dug over.

    Important: For severe contamination, the soil is treated with formalin to avoid the accumulation of harmful substances in plants, the procedure is carried out only in the fall.

    One of the best preparations for treating a greenhouse in the fall from phytophthora is phytosporin. The solution is diluted according to the instructions on the package and disinfect the surface of the greenhouse. Processing should be carried out at air temperature of + 10 ° C and above, low temperature reduces the effect of the drug to 0.

    We also offer to see a detailed video tutorial on how the polycarbonate greenhouse is being processed from phytophtoras in the fall; the whole process of dealing with this ailment is shown in detail in the plot.

    How to prepare a greenhouse in the fall for wintering - useful tips

    We gave detailed instructions on how and what to wash the polycarbonate greenhouse in the fall, but these measures are not enough to prepare for the winter. It is also important to strengthen the building, if necessary to warm, to hold the lighting.

    If in the greenhouse in the fall plants will be planted for the winter, you should warm the foundation with foam plastic plates, wooden shields, cover with foil, and make earth mound. Inside it is recommended to arrange a second layer of film, thin polycarbonate. The air gap between the layers retains heat well.

    In the photo is an example of the warming of the structure in autumn

    In regions with a harsh climate, you should consider heating the greenhouse in autumn: stove, electric, water. The easiest way to install ultraviolet heaters or fan heaters. For the full development of the plants do not forget to spend additional lighting, a set of lamps for lighting must completely duplicate the solar spectrum. To avoid damage to the greenhouse from large snow loads, vertical supports should be installed inside, every 1.5-2 m.

    Frame reinforcement

    Photo 3 Strengthening the frame

    An obligatory stage of preparing the greenhouse for the winter, as it will have significant snow loads.

    To do this, reinforce the inside of the structure with special props. The most optimal will be made in the shape of the letter "T". To place them in the greenhouse follows from the calculation of 1 backup per 2 sq. M.

    If the roof of the greenhouse is flat or we are talking about areas where precipitation in the form of snow usually abundant, you can increase the number of supports.

    In any case, if possible, remove the snow from the roof, so as not to expose the structure to excessive loads.

    Soil disinfection

    Ideally, the soil in the greenhouse changes every 5 years. If this is not possible for various reasons, at least once every 2-3 years remove the top (up to 10 cm) layer of soil and replace it with a new one. The advantage of such a replacement is not only that it is possible to get rid of a significant part of the parasites, but also in the qualitative renewal of the soil composition.

    Regardless of whether the parasites are visible in the soil, it is necessary to disinfect just before the cold in the fall.

    There are a number of universal processing methods that allow you to deal with several types of parasites - rot, scab, blight, etc., and special ones.

    Among the universal methods - treatment with a strong solution of potassium permanganate. To do this, dig the soil to a depth of 15-20 cm, break large lumps and carefully water them with a solution.

    Use a watering can, not a spray bottle. The solution coming in the form of a fine dispersion is not capable of destroying all bacteria and microorganisms.

    If the parasites are visible on the soil and their number exceeds all reasonable limits, the treatment of bleach will be an effective way. Remove the layer of contaminated land and cover it with lime at the rate of 1 kg per 1 sq.m. ground. In the summer you shovel the ground with a spatula or shovel, leave it again. Land will be suitable for planting only in the next season.

    Phytosporin treatment

    Photo 4 Fitosporin

    We carried out the treatment of the greenhouse with this preparation in a separate chapter due to the peculiarities of the use and method of pest control.

    Phytosporin cannot be used on the eve of winter — when the frost is significant, the bacteria die, which makes the drug useless in the fight against pathogenic organisms.

    Phytosporin is a universal drug that protects all cultures without exception from various pests.

    It is an active bacterium Bacillis subtilis, which is located in the soil and actively fights against all known pathogenic organisms.

    It is recommended to use it in spring and several times over the summer (1 month life cycle period) in order to avoid the development of pests. Additionally, photosporin is a type of organic fertilizer, which is also extremely useful for the soil.

    If you notice that the plant has already been attacked by pests and the fruits began to darken, phytosporin will be useless in this case. It is recommended to use chemical preparations.

    Processing methods

    Disinfection of polycarbonate greenhouses, which helps to destroy and further prevent late blight tomato, can be carried out in various ways. It is recommended to do the treatment annually in the autumn after harvesting, but the choice of the method and means for processing depends on the gardener's preferences and on the subject of the treatment (earth or structures).

    Processing facilities can be divided into:

    Structural elements of the greenhouse is easy to handle with the help of chemicals. Temperature and chemical methods will be suitable for disinfecting the soil, but one should not neglect biological methods, which should be attributed to preventive ones.

    Means for processing structures

    When processing structures, special attention must be paid to the junction points of various elements, because it is in the gaps that a large number of phytophtora spores remain. In the autumn it is allowed to use quite aggressive drugs in high concentration, because before planting the tomatoes they will evaporate. But most greenhouse processing facilities require security measures.

    1. Soap solution.

    The easiest and safest tool. It is impossible to defeat late blight tomato only by this means, but it is good to wash the greenhouse before processing with more effective means. The soap solution helps to remove dust and dirt, which will improve the interaction of the stronger drug with the surfaces, which means that the treatment efficiency will be higher. For polycarbonate, such a wet cleaning is almost the only option to preserve transparency.

    Fumigation of greenhouses with sulfur is considered one of the most effective ways. You can simply scatter sulfur on pallets with burning coals, but it is much more convenient to use special checkers for fumigation.

    When burning, a gas (sulfur dioxide) is formed, which penetrates even into the narrowest gaps. But do not forget that for man gas is just as harmful as for pathogens phytophthora. Therefore, when fumigating with sulfur, it is necessary to leave the room and close it tightly immediately after igniting the substance. It is not allowed to enter the greenhouse for 3 days. Also it is impossible to carry out processing near the house.

    ATTENTION! It is not recommended to use this method for greenhouses with a metal frame, since sulfur causes severe corrosion.

    3. Copper sulfate.

    Use a solution of 75–100 g per 10 l of water, which is thoroughly treated on all surfaces.

    Everything must be done in a timely manner, especially the processing of the greenhouse!

    4. Bleach.

    This is the best option for wooden frame greenhouses. To prepare a solution of 400 g of lime insist in 10 l of water for 3-4 hours. The liquid is used to treat the greenhouse surfaces, and the sediment is used to coat the wooden frame. After treatment, it is recommended to close the greenhouse for 2 days.

    5. Fungicidal drugs.

    On sale you can find a large selection of drugs belonging to the class of fungicides of systemic action. They are actively used to protect plants, but in high concentrations can be used for disinfection of greenhouses. The treatment can be carried out with the following preparations: Acrobat-MC, Fitosporin-M, Profit Gold.

    The use of biological methods

    To deal with the causative agents of diseases of tomato, you can with the help of beneficial microorganisms. Increasing their concentration in the soil contributes to its improvement. Microorganisms can be introduced by adding compost, manure or special preparations to the soil, for example, “Baikal EM” and “Shining”.

    The results of the works really pleased

    Such methods will help to improve the soil, restoring the natural balance of microorganisms, but when processing from phytophthora they should be used in combination with other means.

    Watering solutions of drugs

    Potassium permanganate solution is known as an excellent antiseptic. It is actively used not only in medicine and in everyday life, but also as a disinfectant in gardening. To destroy tomato pathogens, it is recommended to shed the earth with a pink solution of potassium permanganate after harvesting all plant residues.

    For irrigation, you can use solutions of effective microorganisms, for example, Fitosporin-M. However, the maximum effect can be achieved only in well-moistened soil.

    Temperature treatment

    Severe frost or heat is detrimental to many microorganisms. Winter frost is the best disinfectant. If it is possible to open the greenhouse better for the winter, and for polycarbonate structures, open the vents and doors. Freezing structures and soil contributes to the destruction of a significant number of spores. After freezing, it is better to cover the ground with snow.

    Sometimes watering with boiling water is used, followed by covering with a film for deeper steaming, but it is better to use this method for early spring treatment.

    Competent approach is a guarantee of success!

    When choosing a method for controlling late blight in a polycarbonate greenhouse, you should not dwell on one tool. The best option is a combination of chemical, temperature and biological methods, because prevention is much simpler than treatment, and an integrated approach has proven its effectiveness many times.

    After fumigation it is necessary to process the soil

    For disinfection used solutions of manganese or chemicals - fungicides. These include Bordeaux mixture, Fitosporin, Redomil, and so on.

    With a small amount of soil, it can be shed with boiling water or boiled with steam. However, large-area greenhouses are inconvenient to handle in this way.

    Also, some gardeners use soapy water to treat both external and internal surfaces of the greenhouse.

    After carrying out maintenance work against phytophthora, it is necessary to prepare greenhouses for wintering. If the greenhouse film, the film is removed, washed, dried and removed. Greenhouses of glass and polycarbonate for the winter remain standing. If there is heavy snowfall in your lane, then you should take care of additional supports. They can serve as a removable metal arc installed from the inside, and wooden T-shaped supports.

    They support the roof of the greenhouse, the load from the snow is distributed evenly. It is also recommended to open the greenhouse for the winter so that there is not a big difference between the temperature inside and outside - this may lead to damage to the glass and polycarbonate. Also, when the snow falls, it is necessary to fill them with soil in the greenhouse. So it will not be damaged by frosts, and in the spring, when the cover melts, the earth will receive additional natural nourishment.

    The gardener's care is not limited to planting, watering and harvesting. Agricultural work involves a large number of auxiliary actions - the creation of natural fertilizer, soil disinfection, treatment of pests.

    Whitefly treatment

    Despite the fact that it is a miniature moth, its colony in a short time can destroy the entire crop. The reason for the emergence of such a parasite is the violation of agrotechnical rules - artificial thickening of the crown, high humidity, constant temperature, rare airing, etc.

    In this situation, the use of sulfur checkers (see above) or the use of chemicals will also help.

    The use of folk methods — an infusion of herbs or garlic — is rational only if the number of parasites is minimal (they caught up in time).In all other situations, we recommend the use of chemicals.

    Among the most popular are the following:

    • Actellic - used at the time of detection of the pest. Diluted at the rate of 1 ampoule per liter of water, this is enough for processing 5 sq.m.
    • Verticillin F - used for prophylaxis and for the fight. It is recommended to use twice with an interval of a week.
    • Confidor - for prevention. It is applied once.
    • Mospilan - for prophylaxis. It is applied once.
    • Pegasus - for the prevention and control of pests. It is applied twice at weekly intervals.
    • Fufanon - for the prevention and control of pests. It is applied once.

    Spider mite treatment

    Another type of parasite that is destructive to plants. Very effective measures to combat this parasite will be:

    • digging the soil
    • greenhouse frame treatment with bleach solution,
    • sulfur checker.

    In general, these measures are quite enough, but it is possible to make a control treatment with acaricides.

    Soil protection and fertilization

    Photo 5 Soil Fertilizer

    While cleaning the greenhouse, we must not forget about the soil where new plants will be planted in the spring. It should be prepared for planting in advance and must be fertilized. When the soil inside the greenhouse is dug up and compost (sawdust, peat and manure) is brought in, it should also be protected from severe frost penetration by sprinkling a layer of hay on top.

    If there is snow outside, then it is recommended that they also cover the ground in the greenhouse. The perfect solution would be to cover the ground from freezing with a special material, in which case it will be possible to start landing as soon as the sun warms and the snow melts.

    If there is a need, the greenhouse can be processed in the spring just as well, using the Bordeaux mixture.

    Cover the ground several times during the winter (no more than 3 times) with snow. You can even combine 2 in 1 - clean the roof and close the beds. The soil moistened in such a way in the spring will be ready under landing even without preliminary preparation.
