Gray rot of tomatoes in a greenhouse: treatment and photos, how to deal with tomato disease with drugs and Fungicide

Gray rot on tomatoes: briefly about tomatoes

Tomato is an annual or perennial herbaceous vegetable from the nightshade family. At the moment, there are more than a thousand varieties. Tomatoes are very often found in gardens and plots. Now it is very difficult to imagine a garden without tomato bushes. Often, gardeners and gardeners organize competitions. In these competitions, the quality of the fruit and its taste are compared. You can consider yourself a real gardener if you get a good harvest and high-quality fruits every year.

Resistant varieties

When choosing seedlings, it is worth giving preference to those that are most adapted to the weather conditions of the area where strawberries will grow. And in temperate climates, the following varieties are more suitable for growing:

Zenith;
Ruby pendant;
Tentra;
Friendship;
Kokinskaya early.

These varieties are characterized by increased resistance to fungal infection. But in the absence of preventive measures, one cannot hope for 100% immunity to gray rot.

To protect strawberries, they need to be cared for properly. And if you react in time to the appearance of the first signs of damage, you can save both the crop and the plants themselves.

A few facts about her.

The first fact about the vital activity of this fungal infection. This disease is caused by fungi - saprotrophs.

The second fact about the vital activity of this fungal infection.

This aerobic disease requires air to reproduce.

The third fact about the vital activity of this fungal infection.

The optimum humidity for her is hundreds of percent.

The fourth fact about the vital activity of this fungal infection.

And the air temperature can be from three to forty-two.

The fifth fact about the vital activity of this fungal infection.

Mycelium is formed from conidia, and under unfavorable conditions, sclerotia. The latter can grow over the next twenty-four to thirty-six months.

The sixth fact about the vital activity of this fungal infection. Spreads by air or moisture.

The seventh fact about the vital activity of this fungal infection ..

Fungi can remain on plant debris, roots or seeds.

The eighth fact about the vital activity of this fungal infection.

This fungus is capable of infecting various plants very quickly. And more than two hundred types of crops fall under its influence.

The ninth fact about the vital activity of this fungal infection. Gray rot, you can also call the kagatnaya word kagat comes from the word heap.This is due to the fact that gray rot infects the harvested fruits and a huge pile of nasty rot is obtained from the fruits laid in a slide.

Types, signs and danger of rot

This disease is fungal in nature, depending on the type of pathogen and symptoms, the disease is divided into two types: fruit and root.

Did you know? In Belgium, in Vepion, there is a strawberry museum, where visitors can buy various edible strawberry souvenirs, as well as taste strawberry beer.

Fruit rot:

late blight - the outer shell of the berries with seeds is compacted, the pulp becomes hard and bitter. After the fruits are covered with dark brown or ink-colored spots, the rest of the ground part of the bush gradually dries out;
white rot - the berries are covered with a whitish fleecy bloom, which gradually creeps onto the leaves and stems. After the mycelium has covered the ground part of the bush, it also affects the root system, covering it with putrid mucus;
gray rot - the fungus penetrates the berries and ripens in the pulp. When it is ready to breed, spores appear on the surface of the fruit in the form of a fluffy gray mold;

black rot, affecting the fruits, makes their pulp watery, discolors the berry. Ripening, the fungus covers the surface of the berry with mucus, gradually turning into black dry spots, with scattering spores.

Root type of the disease:

rhizoctonia - affects young root processes, manifesting itself as black spots. Gradually, the spots merge, covering the entire rosette of the bush, the stems and flower stalks break;
blackleg - disease of the root collar of the plant. It is manifested by blackening of the stem, starting from the point of growth, spreading throughout the bush.

The danger of all types of the disease is that the spores are quickly spread by the wind, affecting the entire strawberry planting. In addition, fungi are omnivorous - if there are beds with other cultivated berries, vegetables or root crops nearby, they also fall into the risk zone and can be destroyed by the disease. The tenacious spores tolerate winter well in the soil, continuing to "eat" the plantings in the next season.

Because of what the disease can occur

Rope Rot Rope rot is an infection, now we will consider why it can appear. There are several reasons for this.

The first possible reason for the appearance of this fungal infection. This is a fungus, ideal conditions for it, it is high humidity and high temperature, under such conditions it will spread. That is, 1 factor is the wrong temperature regime.

The second possible reason for the appearance of this fungal infection. Excessive wetting of the plantings.

The third possible reason for the appearance of this fungal infection. Too much nitrate in the soil.

The fourth possible reason for the appearance of this fungal infection. What a pest, how for, can weaken the plants because of this, the fungus will spread more easily.

The fifth possible reason for the appearance of this fungal infection. Failure to comply with the norms for planting tomatoes, they may sit too close to each other.

The sixth possible reason for the appearance of this fungal infection. You may not have disinfected the greenhouse after the last harvest.

The seventh possible reason for the appearance of this fungal infection. Buying and growing already infected seeds.

The eighth possible reason for the appearance of this fungal infection. Not following the rules of crop rotation.

The ninth possible reason for the appearance of this fungal infection. As mentioned above, the fungus can remain in the soil and various plant residues that remain after harvest, if not enough disinfection and cleaning is carried out, then the fungus will simply appear on the following plants.

The tenth possible reason for the appearance of this fungal infection. Important.Not only tomatoes are susceptible to gray rot, but such plants as potatoes, beets, cucumbers and strawberries.

The eleventh possible cause of this fungal infection. Tomato infections can be transmitted from already infected plants or during planting.

The twelfth possible cause of this fungal infection.

The risk is especially raised if tomatoes are planted on the ground in which previously infected crops were sitting.

How does it spread?

Under favorable conditions, the botrytis fungus forms conidia on the mycelium. These are the spores of the fungus, with the help of which it spreads during one season. In fungi of the genus Botrytis, conidia are colorless or smoky and invisible against the background of a gray mycelium.

Conidia can pass through the air, with drops of irrigation water, with tools. Due to them, the rate of spread of the disease is very high.

In autumn, sclerotia are formed on a gray plaque - dark spots visible to the naked eye, in which the spores of the fungus are enclosed. They are the hibernating phase of mold. Sclerotia are able to withstand frost and lack of moisture. After overwintering in the soil, sclerotia in spring becomes the source of a new outbreak of the disease. They are able to germinate even after three years in the soil. Fungal sclerotia persist on plant debris and seeds.

Gray rot of tomatoes treatment, symptoms of infection

Consider the symptoms of this disease.

The first symptom of this fungal infection. The first and most important thing to pay attention to is a change in the color of the leaves and the appearance of gray spots on them.

The second symptom of this fungal infection.

For the first week, the controversy has not yet spread, and the spots are simply increasing in size.

The third symptom of this fungal infection.

Typical places for the appearance of such spots are places where the plant has been damaged. For example, where the leaves were cut off.

The fourth symptom of this fungal infection. After about seven days, the spots begin to brighten, and a process such as the death of blood vessels occurs inside the stem. Because of this, the leaves turn yellow and begin to dry out.

The fifth symptom of this fungal infection.

After about ten to fifteen days, a gray velvet layer appears on the infected leaves. This is the conidia of infection. After that, the leaves begin to decompose and die.

The sixth symptom of this fungal infection. Transfer the actions of fungi, all plants are infected, first from the shoots of infection it passes to flowers, and so on along the chain.

The seventh symptom of this fungal infection.

From any plant, the disease spreads to another, after a while the whole greenhouse will be infected, and all the bushes will die.

Gray rot on tomatoes: how to treat

There are several guidelines.

The first recommendation to combat this fungal infection.

It is necessary to take timely measures against rot so as not to ruin your entire crop.

The second recommendation is to combat this fungal infection. Many gardeners have vast experience in combating this disease, but scientists still assume that it is easier to carry out prevention than to then cure plants for diseases.

The third recommendation to combat this fungal infection.

Agricultural technology is important here, which must be observed.

The fourth recommendation to combat this fungal infection. High humidity is unacceptable for tomatoes, but despite this, watering should be abundant enough, but rare.

Fifth recommendation to combat this fungal infection.

To prevent excessive waterlogging of tomatoes, you need to ventilate the greenhouse.

You can also mulch the soil with various organic things, such as hay or peat, this can be done if there is not enough time for loosening.

Eighth recommendation to combat this fungal infection. Correct formation is very important for tomatoes.

The ninth recommendation to combat this fungal infection.

Extra leaves must be removed. Treat the wounds that form when the shoots are cut.

The tenth recommendation for combating this fungal infection.

Treatment of wounds is necessary in order to prevent infection from entering the plants. Some wounds can heal in just a day, in sunny weather.

Eleventh recommendation to combat this fungal infection. It is important to ensure that there are no weeds or excess grass on the beds near the tomatoes, and everything that remains cut off must be urgently removed from the greenhouse.

The twelfth recommendation for combating this fungal infection. Watering plants is done at the root, it is better done in specially cut grooves.

Prevention measures

As you know, any disease is easier to prevent than to cure. To prevent the onset of the disease, you must adhere to several rules:

Choose the right place for planting strawberries

In this case, it is necessary:

give preference to areas subject to good ventilation and easy access to sunlight;
avoid places located near large trees and swampy areas;
timely clean the area from fallen leaves and weeds;
choose a place with nutritious and loose soil.

Get rid of weeds

Simultaneously with the removal of weeds, it is useful to feed the strawberry beds with various fertilizers.

This approach will allow you to get a strong and strong culture:

When berries are forming, mulch the ground with sawdust, coniferous twigs or straw to prevent the berries from coming into contact with the soil.
It is useful to sprinkle the ground with sifted ash, which prevents the spread of the disease.
Garlic can be planted near a strawberry plantation, since the phytoncides that make up it help to destroy pathogenic bacteria.

Correct implementation of all recommendations will help you get a rich and healthy strawberry harvest.

Tomato gray rot: biological treatment

To prevent the reappearance of the fungus, drugs are used: trichodermine and glyocladin. It is rather difficult and long to use these drugs, but the effect is very good.

Biological product - Trichodermin.

What is a biological drug - Trichodermin. It is a biologically active substance that contains soil fungi. It is useful against fungal diseases such as gray mold.

In what form can a biological drug be purchased - trichodermin. It can be sold in the form of a powder or an aqueous solution.

A recommendation for the use of a biological preparation - Trichodermin

Cannot be used if the ambient temperature is below thirteen to fourteen degrees Celsius. It is at this temperature that spores are active.

How to use a biological drug - Trichodermin. The tool is used in three main stages.

The first stage of using a biological drug is trichodermin. A solution of trichomedrine can be used to lubricate diseased areas on the plant.

The second stage of using a biological drug is trichodermin. Pranks left after cutting off excess shoots should also be processed.

The third stage of using a biological drug is trichodermin. It is necessary to spray from a spray bottle.

How to prepare a solution from a biological preparation - Trichodermin. It is not difficult to prepare a composition for treating plants from a spray bottle. You need to mix a hundred milliliters of suspension in a ten-liter bucket of water.

When is it recommended to carry out treatment with a biological preparation - trichodermin. The optimal time for processing is morning.

Biological product - Glyocladin.

A couple of facts about the biological drug - glykladin.

The first fact about biologic is glykladin. Since this drug is also biological, it is based on a fungus.

The second is about a biological preparation - glykladin.

The fungus enters gray mold colonies and destroys pathogens.

The third is about a biological drug - glykladin. This product is absolutely safe for the environment, both for people and animals.

How to prepare a solution from a biological preparation - glykladin.

To prepare a solution for processing, you need to mix five tens of grams of solution in a liter of water.

Prophylaxis

Since gray rot spreads almost at lightning speed, it is difficult and tiring to deal with it.

Initially, you must follow the planting rules, and then you need to take care of the strawberries.

Preventive measures, if not completely save from infection, will help to avoid rapid spread. The plant will avoid rot if:

they are planted in a well-lit and ventilated place;
were not injured during planting, the more mechanical damage, the more vulnerable the bush;
when planting, the rules of agricultural technology corresponding to this variety were observed, i.e. planting density, planting site, adjacent crops;
the soil is loosened and dug in a timely manner;
the plant is fed, but not overfed.When overfeeding, strawberry leaves begin to grow at an accelerated rate, shading the berries and retaining excess moisture in the ground;
weeds are regularly removed;
planting is thinned out, excess leaves and whiskers are removed;
diseased berries are immediately removed;
before flowering, treated with a 1% solution of Bordeaux liquid or a weak solution of potassium permanganate, it should be pinkish;
excellently repels gray rot mulching. It is permissible to mulch the soil with sawdust, pine needles or straw, that is, waste from grain processing. Hay, dried grass, is not suitable, as it retains moisture;
you can cover the ground with a black film and place the seedlings in the slots, but you need to follow the instructions exactly in order to prevent the accumulation of water;
harvest completely and cut off all leaves so that new shoots can grow before frost.

You can choose varieties with long and powerful peduncles that can support the berry by weight. But each variety has its own indisputable advantages, the disadvantage of which may be insufficiently long and strong stems.

Mulching

If, during the flowering period of strawberries, the bushes are overlaid with stalks of rye, then later ripening berries will appear above the surface of the earth.

Mulching and the use of film require additional costs. A more economical option is to place plastic tubes or wooden slats on supports along the beds, on which flower stalks are laid.

Alternatively, disposable forks are suitable, which are stuck into the ground with teeth upside down, and peduncles are fixed between them, if they are large, then a couple of teeth should be broken off.
A multi-tiered slide - a pyramid, with wooden frames looks beautiful. Strawberries are planted in each tier around the perimeter. With this planting, the berries hang from a hill onto a wooden wall without touching the ground, so the berries are clean. By planting the bushes in tiers, they take up less space and are easy to pick.

Gray rot of tomatoes: chemical treatment

Chemicals are fungicides and are used to protect against fungi. There are several guidelines.

First recommendation.

In order to get rid of the fungus on one or two plants, you can simply anoint the damaged areas with a special substance, if you have a large infection surface, spraying should be carried out.

Second recommendation. If the infection is small and covers a small number of plants, then such preparations are used as: 1) ditan m - 45., 2) Bordeaux mixture., 3) integral., 4) speed., And 5) profit.

Third recommendation. Experienced gardeners often use Hom and Oxychom for processing tomatoes.

Method with a drug called euparen

About a chemical called euparen. Euparen can be used to kill fungal pathogens. It is sold as a powder and is based on dichlorofuanide. This substance prevents fungi from multiplying by spores.

How can you use a drug called euparen?

There are several guidelines.

First recommendation. To apply the drug to tomatoes, it must be diluted in water to a 2% solution.

Second recommendation.

It is important to read and follow the dosage indicated in the instructions.

Third recommendation. In order to treat already damaged areas, you can prepare a special paste.

Method with glue kmts.

What you need to use KMTS glue. You will need kmts glue, thirty grams of any chemical preparation, and a ten-liter bucket of water.

How to cook.

First, you need to dissolve the glue in water, then add the fungicide there. In the process, a viscous mass should be obtained.

How to use.

It is necessary to process the infected plant tissues, while slightly going beyond the edges of the lesion.

Is a repeat procedure necessary.

The procedure is repeated after ten to fifteen days.

Processing strawberries from rot with folk remedies

Iodine is an effective protection against various types of rot.It is used to prepare a composition in a proportion of 10 drops per 10 liters of water. Spraying must be done at least 1 time per week, both as a prophylaxis and when signs of a disease appear.
Mustard solution is also used against rot. To process strawberries in spring, prepare with a composition prepared according to the recipe of 50 g of dry powder per 5 liters of water. It should be hot, but not boiling water. The infusion time is 48 hours. The composition is filtered and diluted in a 1: 1 ratio.
