Victoria berries are rotting. We save the strawberry crop from gray rot

The topic of today's article is strawberry pests photo and their treatment. Strawberries are grown by many summer residents for the sake of sale, for their diet. It is believed that the culture is not demanding on the conditions of detention, rarely gets sick, and gives a rich harvest.

The berry is conditionally divided into two types:. Proper care, disease prevention, allows you to save the crop as much as possible.

In this article, we will look at what strawberry pests are, their treatment, preventive measures.

The most common reason strawberries wilt is not enough water. How often do you water the plants, monitor the soil moisture? If there is order with watering, there are suspicions that or has started in the garden.

Both of these pests do underground passages feed on the roots of the culture. As a result, strawberries can fall as if cut down, and not just wither. Medvedka is not so easy to catch, she adapts to folk methods.

The first preventive measure is preparations directly into the hole to the roots during the planting of young animals, caring for adult plantings. In autumn, you can make a trap for a bear. To do this, a hole is dug up to half a meter, filled with horse manure.

Medvedka from all over the garden will crawl there to spend the winter, it is warm in the pit. With the onset of cold weather, pests are destroyed, and the remaining manure is used as for the earth.

The reason for the withering of strawberries may be in phytosporosis, verticillosis or fusarium. These diseases are treated, bought at a gardening store.

In addition, strawberries can also wither from root rot. As soon as the plant loses its appearance, you must immediately determine the reason for this. Early diagnosis is 50% of the cure.

Why strawberries dry what to do

Strawberries dry up instead of fruiting? The reason for this may be the diseases listed above. Additionally, the culture is checked for fungal infections.

Strawberries dry from late blight, verticella wilt, gray rot, spotting and powdery mildew. Before starting preventive measures, diagnostics are carried out.

Found damaged bushes are dug up and burned. In the case of a large affected area, heavily affected bushes are burned, the rest of the plants are treated with fungicides.

This situation occurs due to the defeat of gray rot even at the stage of fruit set. The best treatment for these diseases is prevention.

In autumn and spring, strawberries are treated with special means, they adhere to the technology of plant care.

Rotting berries are another problem that can deprive you of your harvest. Its cause is root, brown or black rot. Diseases are caused by fungal spores. Favorable environment for the development of pests - high humidity.

Sometimes rot develops in conditions when bushes of culture grow too densely in a small area, there is nowhere for strawberries to grow. Ripening fruits cannot breathe, touch the damp ground and begin to rot.

As preventive measures, it is recommended to do soil mulching, pouring the earth between the bushes with small sawdust and timely removal of rotten fruits. Make sure that the green berries do not touch the ground. From this strawberries rot and rot.

Closer to autumn, strawberry leaves turn reddish. This effect is considered normal due to the loss of pigment, the beginning of wilting, the culture is preparing for wintering.

At the same time, septoriasis disease appears with red spots. It belongs to the fungal group of pests that can ruin the crop. Sometimes with reddish leaves, the plant reacts to the acidic soil of the site.

You can correct the situation with the help of dolomite flour. If it did not help, then the cause is not in the earth and the disease needs to be treated.

The cause of the yellowness of the leaves may be chlorosis of a non-infectious type. This suggests that the root system of the plant cannot provide it with normal growth, nutrients lacks.

The problem is solved by fertilizing with preparations containing iron and regulating the irrigation regime. Another cause of yellowing leaves is xanthosis.

The people of this pest are called jaundice or mosaic. Most often, the disease is introduced with aphids. Aphids can really be driven away by folk methods, xanthosis is not treated. Take the time to prevent this disease.

In spring and autumn, plants are treated with 3% Bordeaux liquid or 1.5% nitrofen solution. This is enough to grow a healthy culture.

With the advent of the harvest, there are more and more people who want to eat strawberries. Berries are eaten by birds if nothing is done about it. The simplest protection is pegs around the perimeter of the beds and a large mesh thrown over them.

Another way is to hang New Year's rain on twine. For this, meter-long sticks are driven around the beds, ropes are hooked, rain or tinsel is hung on them. When the wind fluctuates, the tinsel will rustle, scaring off pests.

The slug will not be able to crawl to the strawberries through such an obstacle. If they have already appeared, radical measures such as potassium salt, superphosphate are selected, they are scattered around the site.

The substance irritates the surface of the larvae. But, you need to do it several times a day, with a frequency of an hour. Film is considered effective. It creates the effect of a steam room and the worms die. For the same purpose, Meta or Thunderstorm funds are used.

Weevils infect raspberries, strawberries, strawberries. The pest hibernates between old leaves on the ground. A female is considered terrible, gnawing strawberry stalks, eating out buds and laying eggs there.

The beetle is quite dangerous, each female is able to eat up to 50 pieces of flowers. If the pest was found, you need to treat the bushes, karbofos, corsair or another drug from this group.

See instructions for dosage. Processing is done a week before the flowering of the plant. Prevention of the appearance of weevils is done in the spring before flowering or in the fall after the departure of the berries. The preparation Zolon or Aktellik is used, how to use them is written in detail in the instructions.

Voracious larvae are able to destroy the roots of an adult pine tree in a day, what can we say about strawberries and bushes. The pest is considered dangerous, the larvae are collected by hand, then destroyed.

A good way to prevent and combat larvae is the treatment of bushes with Nemabakt. Efficiency up to 90%, contains living organisms. Read the instructions carefully before using the product.

In the folk way, you can only do the prevention of the appearance of larvae. 0.3 wind onion peel, poured with a bucket of water and infused for 5 days. Then the infusion is diluted with another bucket of water and the beds are watered with it. Strawberries become unattractive to slugs.

The beetle reaches a size of 4 millimeters, has a yellow-brown color. It feeds on strawberry leaves and its flowers. If you do not pay attention to the appearance of a pest, then there will be nothing to save. Beetles destroy all the greenery in the garden in a matter of days.

Females lay hundreds of eggs, the larvae appear after a couple of weeks, begin to feed intensively. Get rid of the beetle mechanically possible only at the first stage of its appearance. In the future, special preparations are used.

Adult beetles can really be caught with a special trap with a light source. For this, a deep basin is taken, a light source is placed on its bottom, and the edges of the basin are coated with a sticky agent.

The beetles flock to the light, but they can no longer get out of the basin. Harvest pests at dawn and systematically destroy them.

- beneficial insects, provided that they do not live in a garden with strawberries. Here they can do trouble. Ants eat the strawberry crop and bring aphids with them.

Even from biology it is known that ants grow aphids for their food. As a result, together with such guests you get a double pest in the beds.

An effective remedy for ants is considered to be a slow-acting poison. Poisonous food is laid out in the garden, the ants take it to the nursery, feed it to their family, the uterus, and die with the whole colony. The method of destroying pests is not very ethical, but very effective.

Nematode - microscopic insects that damage the leaves of strawberry bushes, spoiling its stalks. The pest enters the garden mainly with plant seedlings, so be careful what seedlings you buy.

It is quite possible to get rid of a guest on early stages when the affected area is small. You can get rid of the nematode only with special preparations or a thermal solution. How to cook it is better to check in the store for summer residents. Each tool has its own technology of use.

Strawberries suffer from cobweb and strawberry . Both of these pests multiply rapidly, feed on plant sap, and lead to the destruction of entire strawberry plantations. After ticks, dry, twisted leaves remain.

Preventing guests is easier than getting rid of them. A measure of prevention is the spring and autumn treatment of plants with phosphamide, metaphos or karbofos. Another similar treatment is carried out before the strawberry flowering period.

If you are late with prevention, and there are already ticks, you can pour them with a hot solution of potassium permanganate. The temperature of the liquid must be at least 65 degrees Celsius. The ideal environment for ticks is dry soil. Adjust the watering regimen for plants.

In general, caring for strawberries does not create problems, and timely prevention of diseases and pests will allow you to get a rich harvest.

Gray rot on strawberries is a fungal infection of the berries and the whole plant. It is impossible to confuse this disease with others.

Its external manifestations fully correspond to the name - the berries are covered with a gray layer of "fluffy" mycelium, rot, spread gray clouds of spores around them, continuing to infect everything around.

AT different years, depending on weather conditions, gray mold can destroy from 50 to 90% of the berry crop. It is impossible to defeat such an enemy once and for all. The causative agents of the disease live in the soil, plant debris, do not die when frozen in winter and dried out in summer.

But this is not at all a reason to give up, because gray rot threatens many vegetables, berries, even rose bushes. Disease control methods are the same for all crops, they will help keep the garden healthy and fruitful.

Strawberry varieties resistant and susceptible to gray rot

There are no varieties of garden strawberries that are absolutely immune to gray rot. From year to year, under different weather conditions, the incidence of varieties fluctuates. You should choose early ripe varieties - quickly ripened berries do not have time to "stale" and get sick. But among them there are varieties with tender pulp, which is easily affected by the fungus.

Strawberry varieties resistant to gray rot:

Leningrad Late;
Aliso;
marvelous;
Ruby Pendant;
Redgontlite;
Early Dense;Talka;
Beam VIR;
Olympus;
Festival Chamomile;
Ducat;
Bravo;
Fireworks;
Bohemia.

Strawberry varieties highly susceptible to gray rot are varieties such as:

Hope;
Beauty of Zagorye;
generous;
Krasnoselskaya;
Cinderella;
Zenga Zengana;
Relay race

Causes of gray rot on strawberries

Sooner or later, every summer resident faces this garden infection. It is important to know that the following factors increase the risk of a problem:

how high humidity
over watering
frosts
as well as an abundance of weeds in the garden

Spores of a dangerous fungus are spread by moisture or carried by insects from a diseased plant to a healthy one.

External signs of gray rot

It is easy to identify plants affected by gray rot - individual dark spots first appear on the berries, which grow very quickly, covering the entire berry with a thick grayish coating (these are the spores of the fungus). Brownish spots with a gray coating also appear on the leaves.

Earlier than others, strawberries fall ill with gray rot, which are in direct contact with the ground and with affected plant debris. The disease develops very quickly, especially if it is rainy and cold weather. If, when caring for garden strawberries in the spring after flowering, the soil is mulched with hay, straw, sawdust, etc., then the possibility of infection of the berries will be significantly reduced.

The development of this disease is facilitated by plantings thickened and overgrown with weeds, where constant humidity contributes to the germination of spores of this fungus.

Prevention of strawberries against gray rot

Keep soil free of weeds
Sprinkle the soil with ash or lime
Shortly before flowering, it is useful to treat the planting with Bordeaux liquid or the Barrier preparation.
After harvesting, all leaves must be removed from the plantings, but this must be done in such a way that healthy leaves can grow on the bushes before the onset of frost.
It is advisable to alternate rows of strawberry bushes with rows of onions or garlic.
At least once every three years, change the place of cultivation of the crop.
Use pine litter or straw as mulch.
Timely and completely remove diseased berries.
Harvest ripe crops quickly and completely.

Varieties in which flower stalks are located above the leaves are less affected by rot.

Chemicals against gray rot on strawberries

In the fight against gray rot with chemical methods, it is very important to carefully cover the entire plant with a solution of the drug. The first treatment should be carried out at the beginning of flowering, and in case of an emergency, it is necessary to continue treatments every 5-7 days until the start of harvest, observing the waiting period for preparations. As a rule, 3 or 4 treatments will be needed when growing outdoors, 1 or 2 treatments may be sufficient in protected ground. The fight against gray rot in plantations of neutral day varieties becomes especially difficult - simultaneous flowering and harvesting does not allow the use of most drugs, so it is important to use drugs with short period waiting or using biological control methods. One more important part proper chemical protection is the right choice of drugs.

Alirin-B. Biological fungicide in tablets. Processing of strawberries with Alirin-B is carried out in 2 stages:

before the flowering phase - 1-2 times;
after flowering - 2-3 times (re-spraying a week later until the signs of infection disappear).

The norm of the drug is 2-3 tablets per 1 liter. water, for prevention - 1-1.5 tablets. They are pre-dissolved in a small container, and then the liquid solution is added to the total volume.
Fertilizer for pepper seedlings at home

It is recommended to carry out no more than two sprayings with a minimum interval of 7 days. The average rate of the drug is 10 g per 5 liters. The dose is dissolved in 1/3 of the required volume, after which the reservoir is completely filled.

Processing strawberries from rot with folk remedies

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

Unfortunately, despite the constant work of breeders, strawberry varieties that are resistant, for example, to diseases such as black rot or gray, have not yet been bred. This trouble is especially annoying when it is a rainy summer and quite cool. During such a period, there is a high risk of losing more than half of the crop. The gardener must know how to treat strawberries from gray rot in order to protect the plants and get an excellent harvest.

What does gray mold look like on strawberries?

Gray mold on strawberries

The first sign that you need to pay close attention to is the appearance of individual brownish spots on the berries. These marks grow catastrophically fast, while they are overgrown with a dense grayish coating. On such a surface, if you look closely, numerous small disputes are determined. They are the carriers of damage carried by the wind. The disease spreads to leaves, stems and rhizomes of plantings.

When the gardener should be especially careful

High humidity over a long period of time.
Heavy dew at night.
Lots of precipitation at one time.
Excessive watering.
Cool temperature conditions - up to +15 degrees.
The presence on neighboring beds of other plants infected with this "ailment".
Plantings are thickened and all in weeds.

Late blight rot of strawberries: not to be confused with gray rot

Late blight rot

There may be another type of rot on strawberries - late blight, caused by Phytophthora cactorum fungi. It affects all ground parts of a strawberry plant - leaves, berries, flowers, buds, growth points. Most of all gets from this disease to berries. Ripe fruits are covered with brownish spots of a leathery texture with a lilac tint. The berry loses all its magnificent taste qualities acquiring bitterness. The pulp is rough. In green fruits, the disease manifests itself in the form of light brown spots - a darker spot in the middle, and a kind of border is obtained along the edges. After some period, the fruits dry out and mummify. Plaque forms on all infected areas white color. There is necrosis of the growth point, the stem becomes brown, the stems die off at the base, the rosette of the bush is damaged.

Important! Diseased tissues contain fungal mycelium, at the same time zoosporangia are formed there - spores that are activated in summer and oospores - winter spores.

And the roots can be affected by root rot

root rot

It is also about a fungal disease. It manifests itself in the form of a sharp blackening of small areas of young light roots. After some time, the spots grow and become ring-shaped. Appeared dry constrictions make the roots brittle. Strawberries become oppressed, shoots either do not form at all, or appear very weak. Risk of crop loss up to 100%. Over time, dry rot on the roots kills the plant.

Important! Root rot, very often appears on the beds, where only strawberries grow from year to year. Also, you can not plant this crop at the place where potatoes are grown. This trouble can appear at any time during the vegetative period.

How to deal with rot on strawberries

Prevention

The fight against gray rot first of all begins with the creation of favorable conditions for the development of plants and competent care for them. So, this mushroom will not like it if:

the strawberry garden will be located in a well-ventilated and lit place;
the soil is processed properly and in a timely manner - digging, loosening, mulching (straw, needles), top dressing (do not overdo it with nitrogenous fertilizers that increase foliage growth);
according to the agricultural technology of a particular variety, planting density is maintained;
the fight against weeds, which play the role of infection reservoirs, is tirelessly carried out;
rotten and diseased berries are quickly removed from the garden.

Important! When planting plants and at the time of the formation of young rosettes, injuries should be minimized. The less damage, the less possible foci of rot.

Periods of application of chemicals

Off-season

To prevent rot from appearing on strawberries, it is necessary to start the fight in the fall. So, in the first decade of November, it is worth carrying out preventive spraying with a special chemical preparation. If at this time the procedure was not carried out, then it can be carried out in the spring - in early March.

vegetation

I time - with the growth of leaves.
II time - the end of budding.
III time - after harvest.

Important! Putrefactive mushrooms tolerate even very frosty and snowless winters without any problems. The “enemy” is not destroyed during autumn digging or other earthworks. It makes sense to carry out antifungal measures only in spring and summer.

Popular preparations for strawberry rot

"Horus"

Fungicidal agent against disease infestation fungal species. Maximum efficiency is achieved with temperature regime slightly above +3°C, but before the onset of heat. Therefore, you need to use the tool immediately with the onset of the season. When setting high temperatures of +25°C, a high initial activity and a fungal-extinguishing ability are observed, but the protection period is significantly reduced.

This strawberry rot remedy has an anti-resistance solution, is quickly absorbed by the plant and is not washed away by rain. The drug is economical - the consumption is ten times lower than that of most other contact preparations. Phytotoxicity is absent. The consumer is supplied in a convenient preparative form and packaging.

"Teldor"

Modern fungicide

A fungicide of local systemic action, supplied in the form of water-dispersible granules (WDG), will allow preserving strawberries. It can be used at any stage of plant development. Helps to preserve fruits during storage and transportation. Once on the surface of the plant, drying agent forms a film that protects against the penetration of pathogens deep into the tissue. It is characterized by localized systemic action.

Important! Among other effective drugs that will get rid of a fungal disease, you should pay attention to Acrobat, Bayleton, Euparen, Fundazol. What to do with them to achieve maximum effectiveness is indicated on the packaging of each product. It is very important to scrupulously adhere to the indicated recipes and spray strawberries according to the recommended schemes.

effective protection against various kinds rot is iodine. It is used to prepare the composition in the proportion of 10 drops per 10 liters of water. Spraying must be done at least once a week, both as a preventive measure and when signs of the disease appear.
A solution of mustard is also used against rot. To process strawberries in the spring, prepare with a composition prepared according to the recipe of 50 g of dry powder per 5 liters of water.

Hello dear gardeners. Today we’ll talk about gray rot, a pressing problem that affects strawberries.

In this article, you will read why rot affects strawberries, the main causes and signs of the disease. I will tell you how to deal with it with modern drugs. How to process bushes, processing time.

Also learn about folk methods treatment with iodine and potassium permanganate, treatment with garlic and mustard. About preventive methods - what to do to prevent infection. Another practical mega article!

Strawberries are a favorite berry of Russian gardeners, however, the harvest of this crop can ruin dangerous disease- gray rot.

Unfortunately, breeders have not yet received a variety that is resistant to infection, so summer residents risk losing their sweet treat in rainy summers.

Proper processing of strawberries helps prevent unpleasant consequences and cope with the disease. About what means are considered effective, this article will tell.

Causes of gray rot on berries.

like high humidity
over watering,
frost,
as well as an abundance of weeds in the garden.

Signs of infection.

The presence of gray rot on strawberries is indicated by the following symptoms, which should not be ignored:

smoky coating on the surface of the berries;
watery pulp;
the appearance of dark spots.

It also happens that large and healthy berries hang on the bushes, and the affected specimens are located next to them.

In addition, often fungal plaque is located on reverse side strawberries, which is very frustrating for the summer resident.

All aboveground parts of the plant are at risk, so you should be aware of what gray rot looks like.

Fungus chemicals.

Damage to the crop, death of plants and contamination of the soil with spores of the fungus - all this brings gray rot, control methods can be radical and consist in treating the beds with fungicides.

Before the procedure, remove infected berries and leaves, and uproot weeds.

Alirin-B

The preparation for gray rot "Alirin-B" is applied before and after the flowering phase, and the secondary spraying is carried out 2 weeks after the first treatment.

Dissolve 2 tablets in 1 liter of water.
Mix the liquid well and start spraying.

This tool is effective after the first application and allows you to quickly defeat a fungal infection.

As a rule, 2 fungicide treatments are enough to save the garden from adversity.

They should be planned on a dry day, as precipitation reduces the effectiveness of the drug.

The drug "Switch"

The two-component preparation "Switch" is also suitable for spraying strawberries; it also fights powdery mildew and fusarium.

Plants can be treated before and after flowering, the recommended interval between treatments is 7 days.

Experienced gardeners advise taking 10 g of funds per 5 liters of water and proceed to protect strawberries from fungus.

Treatments after harvest.

The fight against infection through the use of fungicides does not take much time, such drugs are very effective and help save the berry crop.

Preventive spraying is carried out before flowering, as well as 2 weeks before harvesting berries.

If you find the slightest sign of gray rot, immediately start processing the plants, otherwise the fungus will infect all plantings.

After harvesting, do not forget to process again garden plot one of the indicated means. If it is not possible to resort to fungicides again, then it is recommended:

Spray the beds with Bordeaux liquid - a solution of copper sulfate at a concentration of 1%.
It is also necessary to burn the plant remains of the affected bushes and berries.

In autumn, it is important to do everything in order to prevent the development of a fungal infection next year.

Folk remedies for the fight against fungus.

Not all gardeners want to use chemicals to get rid of gray mold on strawberries.

You can protect the berries with the help of ordinary iodine, which is in every gardener's first aid kit. This simple and affordable tool kills the fungus, thereby saving the future crop with small lesions.

With the help of iodine.

Processing strawberries from the disease in the spring consists in spraying the plants with the following composition:

iodine (15 drops);
whey (200 ml);
warm water(10 liters).

The procedure is carried out before the flowering period from 2 to 3 times, but at the stage of berry formation it is better to refuse it.

But there is no need for this, since iodine in combination with a dairy product effectively fights the causative agent of gray rot. This recipe has proven itself well and is used by more than one generation of summer residents.

The mixture quickly evaporates from the surface of the leaves and acts directly on the fungi.

Potassium permanganate.

Proven and safe methods of control include the treatment of bushes with potassium permanganate. For this:

dissolve in hot water (temperature up to 50 ° C) a little potassium permanganate, the mixture should turn out bright pink.

Experienced gardeners advise adding a few drops of boric acid to this solution, this action increases the effectiveness of spraying.

Spraying before flowering will not harm strawberries, moreover, the procedure prevents the development of a fungal infection and repels pests.

Garlic processing.

Not all people know that ordinary garlic acts quickly and helps to cope with gray mold. Before treating plants with chemicals, be sure to forgive the benefits of an available vegetable, and you can prepare a solution from the following components:

garlic;
laundry soap;
water.

Peel a few cloves and grind thoroughly with a meat grinder.
Then fill the product with water in a separate bowl.
Close the lid tightly and place in warm place for 7 days.

The resulting solution is suitable for spraying.

Soap solution.

To enhance the effectiveness of the solution, add 50 ml of the garlic solution (described above) to water and a bar of soap (10 liters) and carry out a preventive procedure.

The soapy solution will stick to the leaves of the plants, thereby the active substances of garlic will quickly rid the strawberries of gray rot.

We use mustard.

Regular mustard will also help save strawberries from gray rot.

Take 50 g of dry powder and fill it with 5 liters of hot water.
Next, infuse the mixture for 48 hours.
The resulting solution is diluted with water.

And they are used for spraying before or after flowering, in addition, this method can be used shortly before harvesting.

Like other folk remedies, natural mustard inhibits the growth of the fungus, stops the spread of infection in the garden and destroys the spores of the pathogen.

Preventive measures against gray rot.

Beginning gardeners choose the wrong place for strawberry beds, and then look for information on how to deal with the disease.

Place for landing.

In order to prevent trouble, you should:

Choose a well-ventilated and bright area away from big trees and swamps.
And also it needs to be cleaned of fallen leaves and weeds in time.

The best place for culture is the middle of a suburban area, where the soil is nutritious and loose.

Remove weeds.

Do not be lazy to remove weeds and fertilize plants, thanks to proper care the bushes will be strong and strong, which means that they will not be afraid of the infection.

During the formation of berries, mulch the aisles with a thin layer of clean straw, and you can also use sawdust and needles so that the strawberries do not come into contact with the ground.

Wood ash inhibits the spread of gray rot, which is why it is recommended to sprinkle the ground between plants.
It is useful to plant garlic next to strawberries, as the phytoncides in its composition destroy the spores of a dangerous fungus.

Whatever the measures to combat the attack, it is much easier to prevent garden disease.

That's all for today. Preventive measures and early treatment of the bushes will help you get a rich berry harvest. See you soon for the new summer season!

Gray rot destroys the strawberry crop. How to save berries: methods of dealing with rot, eliminating the causes

Variety selection

The varieties most resistant to gray rot were: Mitse Schindler, Pavlovskaya Beauty, Novinka, Druzhba, Pocahontas, Ruby Pendant.

Rot on strawberries, causes of the disease

Fungal spores are always present in the soil and air, but they can grow uncontrollably and harm plantings only under certain conditions:

Poor choice of landing site. Strawberries need a lot of sun, even partial shade is not suitable for her. The area reserved for strawberries should not only be well lit, but also well ventilated. With stagnation of air (between buildings, hedges, in lowlands), the development of gray rot on strawberries is a matter of time.

The thickening of the beds. Strawberries form bushes of various diameters depending on the variety and care. Standard scheme landing may not be suitable. If a dense shadow forms on the bed under the bushes, the earth does not warm up by the sun, it is not blown by air. Strawberries should be planted, thinned out, which will provide access to air and light.

Increased humidity. The fungus loves moisture, quickly develops in beds flooded with rain or excessive watering. It is worth carefully monitoring the moisture content of the soil, if possible, cover the strawberries from untimely rains, and loosen the soil.

These are the main causes of rot on strawberries. We will consider the methods of struggle at different stages of plant development below.

How to prevent gray rot on strawberries

Gray rot spores overwinter in the soil and plant debris on the surface. Last year's mulch and dry leaves are especially dangerous; in the spring they should be removed.

Fertilizers (both organic and mineral) used for strawberries serve as a good prevention against fungus. They act in two ways:

1. Disinfect the soil.

2. Strengthen the plants themselves.

Strong bushes get sick less and are affected by pests. Timely potash and phosphorus fertilizers introduced into the soil significantly reduce the risk of fungal infections.

In areas particularly prone to disease, spring nitrogen fertilization (including manure) should be avoided. nitrogen serves nutrient medium for the fungus, contributes to its development. In addition, the bushes that have grown violently on nitrogen obscure themselves, and are less ventilated.

After any watering or top dressing, the earth must be loosened.

Experienced gardeners advise planting onions or garlic between strawberry bushes, their natural phytoncides inhibit the development of rot and repel pests.

In the budding phase, just before flowering, strawberries are sprayed with compositions from gray rot.

Chemical and organic agents that inhibit the growth of the fungus:

Mustard infusion. Add a glass of mustard powder to a bucket of hot water, insist at least a day. Also use an infusion of garlic. To do this, add one glass of chopped garlic cloves to 10 liters of hot water.

Copper chloride is diluted with water in accordance with the instructions on the package. For better adhesion to the leaves, a little skimmed milk is added.

Organic fungicides figon, fuklazin and thiram (TMTD). The best results in the fight against gray mold on strawberries were shown by the drug thiram. The incidence in the experimental plots decreased by 3 times.

Processing can be repeated already on the ovaries. All of these drugs act on strawberries as a fertilizer, heal bushes, and significantly increase yields.

Attention! Improper watering contributes to the appearance of rot on strawberries. The outbreak could be caused by cold water or sprinkling after the start of flowering. After the flowers appear, only the soil should be watered.

Before the berries appear, care should be taken that when they ripen they do not come into contact with the ground. Mulching with fresh straw, pine needles, at the same time keeps the soil loose and protects the berries from infection with fungal spores.

After harvesting, strawberry beds are fertilized with full mineral fertilizer (with nitrogen) or rotted manure. Fresh manure provokes the growth of the fungus, its use on strawberry beds is not desirable.

At the end of the summer, several more preventive sprays are carried out with antifungal compounds.

Compliance with such agricultural technology for one year gives a noticeable result - the incidence is reduced. After a few seasons, cases of the appearance of gray rot become isolated.

Mulching agrofibre prevents rot on strawberries

Methods for combating rot are greatly simplified when growing garden strawberries on agrofiber. The structure of the black covering material allows the soil to breathe, quickly absorbs moisture. Berries quickly dry out after rain, do not come into contact with the soil, which excludes their infection with fungal spores.

Black mulching materials speed up the maturation of the crop. Berries do not have time to get sick even in rainy weather.

The black film prevents air from entering, therefore it is not recommended as a mulching material for beds.

Gray rot on strawberries, how to treat if it has already appeared

How to deal with trouble if there is no time for prevention, and the first diseased berries are seen on the beds?

1. Sick berries are carefully removed from the bushes, dropped away from the beds. Do not throw infected plant parts on the compost heap.

2. If the bushes are too thick, cut off the extra leaves, if possible thin out the plantings.

3. Pollination with ashes often gives good results. When loosening, it is advisable to plant some ash into the soil under each bush.

4. Stop watering, let the topsoil dry and ventilate.

5. Spend foliar top dressing potassium permanganate and boric acid (2 g each) with the addition of 20 drops of pharmacy iodine for every 10 liters of water. When spraying, try to get on the lower surface of the leaves.

It is important to ensure that the berries do not touch the ground. You can use any coasters, frames to support flower stalks, mulching, tying bushes.

The main rule in the fight against fungal infections is to create conditions in which rot does not develop, and strawberry bushes grow stronger. The sun and air are the main helpers in the fight against rotting berries.

Do not put up with gray mold on strawberries. You now know how to treat and what to do for prevention. And an excellent harvest is a matter of caring hands and patience.

If, when caring for garden strawberries in the spring after flowering, the soil is mulched with hay, straw, sawdust, etc., then the possibility of infection of the berries will be significantly reduced.

The development of this disease is facilitated by plantings thickened and overgrown with weeds, where constant humidity contributes to the germination of spores of this fungus.

Keep soil free of weeds
Sprinkle the soil with ash or lime
