The infection is most common in areas with temperate climate. The Moniliosis fungus becomes most active in spring or early summer, especially in wet weather. The disease is typical not only for apples, but also for other crops, including stone fruits.

The fungus survives the winter on mummified fruits and produces spores in the spring. In the second half of summer, when high humidity the air temperature rises, massive infection of trees may begin. Moniliosis penetrates the fruits of apple trees and other trees through minor damage.

In this article we will talk about the causes and signs of the disease, and also provide some tips for combating the disease.

Symptoms

Until a certain point, moniliosis occurs in a latent form. Its incubation period is approximately 5 days. And after ten days the sporulation process begins.

The first sign of the disease is the appearance of brown spots on the fruits of apple trees. The marks quickly grow, covering the entire apple. The pulp under the peel becomes loose and tasteless. It is no longer suitable for food.

Over time, gray-white pads appear on the affected area of ​​apple trees, consisting of chains of colorless conidia. The pads are arranged in concentric circles. This is how the fungus behaves during the sporulation period.

Most of the fruits of apple trees are separated from the branches and fall off. Those that remain become hard, blue-black. The infection is transmitted from one apple to the next one growing nearby. The more they mature, the more they become infected. If the affected fruit remains on the apple tree, the fungus moves through the stalk to the fruit branch. This is how neighboring branches of apple trees are affected. In spring, the infection reaches young ovaries. New weak branches of apple trees are also affected by the disease and wither.

A slightly different case is when in the spring conidia fall on flowers, then they spread along the shoot, and a monilial burn occurs. The flowers first turn black or turn brown. Then you can completely observe the drying of the buds. Next, moniliosis spreads to fruit branches, ovaries, and twigs. The foliage on them also changes color and dries out, and then falls off, taking on a charred appearance.

During the season, the fungus produces several portions of conidia, as a result of which the entire apple tree becomes infected.

After the conidial stage, the resting stage begins. However, the fungus does not disappear anywhere. With the start of the new season he will prove himself again. In addition, it spreads very easily to neighboring healthy trees. Not only apple trees, but also other fruit trees are at risk.

Features of the disease

Moniliosis can occur in two scenarios. In the first case, the lesions are fruits, and in the second, flowers, ovaries, branches and leaves (the aforementioned monilial burn).

The most dangerous is damage to the apple tree bark disease. Wounds and cracks appear on it, from which gum is released. Moniliosis leads to drying out of large areas of bark and young branches. In advanced cases gray mold spreads throughout the apple tree.

The fungus easily tolerates winter and does not die. In the form of mycelium, it remains on the fruits of the apple tree (on the fallen ones and on those left hanging on the branches). In some areas, moniliosis fungus winter time the shape of the conidia is more characteristic. In spring, conidial pads form. The disease worsens and continues to progress throughout the entire fruiting period. This period coincides with the full development cycle of the fungus.

Causes

To prevent apple trees from becoming infected with this terrible disease, it is necessary to understand why it occurs. There are many factors for the disease, but among them the most important one can be identified - infection with actinomycetes (a type of bacteria that lives in the soil and on plants).

Other reasons need to be mentioned.

Any cracks or damage to the apple tree bark are a risk factor, through which the microbe enters the tree. Healthy parts of the apple tree may suffer from contact with diseased mummified fruits.

The danger is posed by some pests, or rather the damage they leave in the apple bark. Most dangerous insects in this case are the goose and the codling moth.

Trees suffering from other diseases and phytopathologies are at risk.

Some varieties of apple trees are predisposed to the disease. Their risk of disease is especially high. Also, varieties that are resistant to infection are not one hundred percent protected from it.

It is important to understand that treating trees for moniliosis is useless if infected fruits and branches remain underneath them. They can lead to re-infection or infection of still healthy parts of the apple tree.

In some conditions, moniliosis takes hold of the tree especially easily and progresses quickly. Such conditions include apple tree blossoms.

Some weather conditions, such as hail or strong winds, are also dangerous. It’s not hard to guess why they make trees so vulnerable - anything that can injure a plant is dangerous for it.

Infection with moniliosis can occur if moisture accumulates in the petiole pit.

The fungus is especially active at temperatures above +15 degrees; accordingly, in warm weather the risk of disease increases. As with high humidity air.

Fruits can be infected if they are collected in dirty containers. Dirty tools used for grafting or pruning are also dangerous. Moniliosis actively spreads in windy weather. Why? The answer is again simple. The spores of the fungal pathogen are easily carried by the wind.

Among the factors contributing to the infection: heavy rainfall, snowy winters and cool spring, when slush and cold do not want to give way to summer warmth.

Treatment

We have figured out why the disease occurs, now it’s time to understand what to do if you notice signs of the disease in apple trees.

Under no circumstances should you put off treatment until later; the sooner you take action, the better.

The most important procedure, whether prevention or treatment, is pruning branches that show signs of infection: darkened leaves or fruits, dry tips. It is also important to immediately dispose of the trimmed parts of the tree. It is advisable to burn them at a distance from the apple tree.

If you want to avoid infection, you should Special attention pay attention to harvesting, do it on time.

Alas, if the disease has affected the entire tree, no treatment can bring it back to life.

To prevent this from happening, you need to be especially careful when handling fruits. When collecting and transporting them, mechanical damage should be avoided.

Apples should be stored at approximately 0°C. A strong deviation from the norm can cause fruit spoilage. It is important to focus on disinfecting the premises where you plan to store fruits, as well as process all containers.

For prevention and treatment, apple trees must be regularly treated with fungicides. It is recommended to use drugs such as Mikosan-B, Bordeaux mixture, Horus, Skor.

An important role is played by the treatment of other diseases and pest control. Pests that damage tree bark are especially dangerous. It is important to notice signs of insects in time and immediately apply means to eliminate them. You should not rely on luck; it is important to achieve the complete disappearance of pests.

All this must be done both during the growing season and after it.

Now you know why moniliosis of fruit trees occurs and how to deal with it. Take care of the health of your garden, and it will repay you with lush flowers and a rich harvest.

Every gardener puts a lot of effort and time into his plot, and in return wants to receive good harvest. To do this, it is not enough to fertilize, water and trim the plants. It is also very important to protect the garden from pests, as well as various diseases, which are becoming more and more numerous. Viral and fungal, they spread at the speed of light and lead to the complete destruction of the crop, and sometimes the trees themselves.

Today, more and more often, summer residents are faced with the fact that spring Green on stone fruit trees it becomes covered with brown spots. Many people mistakenly believe that there was an overnight frost, or blame themselves for improper treatment with an insecticide. In fact, this is the activity of a harmful fungus. This disease is called monilial burn. Its prevalence in Russia today has reached incredible proportions, so every summer resident should foresee such a problem.

How to recognize an enemy by sight

This disease did not appear yesterday. If you have been gardening for a long time, then most likely you know what a monilial burn is. It's just called differently in everyday life. This is ordinary gray rot. Various subspecies live on all fruit trees. At the same time, stone fruits are the favorite crops of this fungus and suffer much more severely.

Territorial distribution

Monilial burn is very common in temperate regions. In Russia this is the European part and the north-west, Far East, Caucasus and Ural, Siberia. That is, it turns out that most of the country is suffering. The cherry orchards of Ukraine and Belarus are infected. The problem is becoming almost universal, and regular treatment does not help. Relatively cool weather and rain are excellent conditions for the development of gray rot. At high air humidity optimal temperature are 15-20 degrees. Today, the climate is changing everywhere, and a prolonged spring with precipitation leads to the fact that monilial burn appears even in those regions where it was not found before.

How does infection occur?

Treatment should be carried out before the plants begin to flower. It is from the moment the buds open that the conidia of the fungus penetrate through the pistil into the flower. Here he receives all the conditions necessary for life and development. The mycelium can also infect the wood of shoots. As a result, the gardener observes a rapidly growing monilial burn (cherries, for example). Instead of filling berries, you get drying young twigs. Fungal spores are carried by the wind over a considerable distance, so if there are no diseased trees in neighboring areas, this does not mean that there is nothing to worry about. Insects can also bring them.

First signs

As we have already said, the leaves and shoots become brown in color. Following them, the same fate awaits the resulting ovaries. If the affected plant parts are not removed in time, they themselves will become a source of spores. Monilial stone fruit burn is a disease that should be dealt with seriously. Even unfavourable conditions cannot stop the life process of the fungus. In hot weather, its activity slows down, but at the first opportunity it will again show itself in all its “glory”. Fungal spores are extremely tenacious.

Behind summer period it can produce several generations of spores and take over entire gardens. The spores survive the cold on branches, dried leaves and unripe berries that have become mummified and left hanging on the tree. And with the arrival of the warm season, the development cycle repeats with even greater speed.

At risk

A novice gardener is sometimes surprised that only adult, fruit-bearing plantings are susceptible to damage. At the same time, young trees calmly tolerate their proximity to them, without showing any signs of disease. There is no miracle here. It’s just that the only place through which the fungus penetrates the phloem tissue of the plant is open flower. Therefore, the seedlings are 100% protected.

At the same time, precipitation that falls during the flowering period is vital for spores. The tree itself needs them, since moderate heat and sufficient moisture contribute to the appearance and ripening of fruits. But the same rains create conditions for the development of fungus and reduce the plant’s resistance. Therefore, a warm and rainy spring is a reason to be wary and regularly check your garden. Even if you are not sure that the branch is drying up precisely because of a fungal infection, it is always better to cut it and burn it.

Let's stop the spread

Choosing a variety

Even at the time of purchasing a seedling, you should think about which one will feel best in your region. The stronger the tree, the easier it will survive the attack of the fungus and therapeutic pruning, and will also begin to grow and restore its previous yield. Of course, it is very convenient to plant plants that are completely resistant to such dangerous diseases as cherry monilial blight. Treatment involves the use of special drugs, which can then accumulate in the fruits. I would really like to avoid this.

Breeders have never been able to develop varieties that would be completely immune to dangerous disease. It's a pity, of course, but you shouldn't be discouraged. There are varieties that cope better than others with this scourge. Examples include Anadolskaya and Tamaris cherries, Belarusian varieties Zhivitsa and Rossoshanskaya Chernaya, as well as a number unpretentious varieties for the Moscow region. These are Turgenevka and Molodezhnaya, Radonezh and Bystrinka.

With the right approach, these trees can calmly grow and bear fruit even in an area where there is a massive infestation of monilial blight. At the same time, the amount of harvest will please you from year to year.

Preventive actions

It is much easier to stop a monilial burn. Treatment can be lengthy and quite complex, so pay special attention to this point. good preventive measure is the regular formation of the crown of fruit trees. Removing excess branches, the growth of which leads to excessive density of the crown, as well as cutting out weak shoots reduce the risk of colonization of the crown by pests and fungi. Such pruning is especially important for old, weakening trees. Be sure to trim off all plant debris from diseased cherries.

Mechanical destruction of affected plants

The fight against monilial burn is a whole set of measures that is aimed at completely ridding the garden of the fungus and preventing its occurrence in the future. If you do not want the garden to be completely destroyed, you need to cut out all affected and dead parts of the plants.

Usually the time for a full inspection comes immediately after leaf fall. Diseased and dry branches are cut out, and the wounds are covered with putty or paint. Cut branches and dry debris must be burned. After this, experts recommend spraying the trees with a 6% solution of ferrous sulfate. Take the time to whiten tree trunks and branches with lime milk.

If you were unable to complete these activities in the fall, then they are gradually transferred to the spring. Do not forget that the work must be completed before the buds swell. Cut branches also need to be burned. Now we are carefully monitoring the garden. After the buds swell, you need to spray the trees with 1% Bordeaux mixture. Check again after flowering fruit trees. If old dried branches remain or new ones are added to them, then it is necessary to repeat the pruning and carry out a second spraying with Bordeaux mixture.

Complete cutting down of the garden

This radical solution sometimes comes to the mind of a gardener who is tired of fighting the disease. In fact, this is the worst option. Of course, with the destruction of the trees, the monilial burn will also disappear. The photos presented in the article will help you understand what this disease is. However, by planting new trees, you will again be at risk. Cherries and plums, apricots and peaches should not be chopped, but rejuvenated by trimming skeletal branches. At the same time, a series of preventive and therapeutic sprayings are carried out and a crown is formed that is completely free of fungus. In this case, you will not lose as much time as it takes to grow a new orchard.

Instead of a conclusion

Monilial burn is a serious disease that can quickly leave you without a harvest. The fungus spreads quickly and is dangerous for most people. garden crops. But among fruit trees Stone fruit crops suffer the most. In Russia these are cherries and plums. However, the gardener is quite capable of protecting his plantings. To do this, you need to form the crown of trees, regularly inspect them and carry out timely treatment with iron sulfate or fungicides.

Many people, whether gardeners or hobbyists countryside holiday, more than once we have seen rot on apple trees or their fruits. This disease is called apple fruit rot, which is considered the most common disease of this fruit tree. Another name for this disease is apple tree moniliosis. In terms of its harmfulness, it surpasses even scab.

Fruit rot or moniliosis is a fungal disease that can infect a wide range of plants. The causative agent of this disease is the ascomycete fungus Monilinia cinerea Honey, a marsupial. Fighting it is an important part of caring for apple trees.

This disease is characterized by two stages:

• conidial stage. It is caused by the fungus Monilia cinerea Bon. IN in this case sporulation occurs on all affected areas of the tree, looking like small and gray pads. These pads consist of single-celled chains of colorless conidia. IN spring period conidia infect flowers and, spreading along the shoot, provoke the development of monilial burn. During the growing season, the fungus produces several generations of conidia, leading to massive infection of the entire tree;
• sclerotial stage. This is the so-called resting stage.

Some scientific articles distinguish two forms of this disease:

• fruit rot - the primary lesions are localized on the fruits, which leads to their rapid spoilage and unsuitability for consumption. Develops throughout the entire fruiting period;
• monilial burn or leaf burn - the disease affects flowers, ovaries, branches and leaves, leading to their browning and drying out. While long time on wood, they take on a burnt appearance.

The greatest danger to the apple tree is infection of the bark of the branches, which leads to the development of cracks and wounds on it, from which abundant release of gum occurs. This can lead to drying out of large areas of wood, as well as overgrown branches. In the most severe cases of the disease, the entire tree is affected. The fungus overwinters mainly in the form of mycelium on fruits (fallen or left hanging on branches) and branches. For certain areas (Moldova, Caucasus, Crimea) it can also overwinter in the form of conidia. With the onset of spring, conidial pads form in infected areas, which leads to a spring exacerbation of the disease. The mushroom completes its development cycle during the fertile period.

Causes

There are many factors that contribute to tree infection. However, the main reason that leads to the development of fruit rot is infection of the apple tree with actinomycetes.

The main reasons include:

• various damage to the bark (especially cracks);
• contact of mummified infected fruits with healthy parts of the apple tree;
• damage to the skin of apples due to insect bites (mainly goose and codling moth);
• the presence of other diseases affecting apple trees;
• presence of phytopathologies;
• contact of various parts of the tree with already infected fruits (especially already mummified ones) or branches;
• high susceptibility of a certain apple tree variety to this disease. But often even varieties that are resistant to this disease are powerless in confronting it;
• not destroying infected apples and branches that may accumulate under the tree, thereby facilitating further infection.

Factors that create suitable conditions for infection:

• flowering period;
• past hail;
• infection is possible through the petiole pit, but subject to the presence of droplet-liquid moisture in it;
• air temperature about +15 degrees;
• high air humidity (70% and above);
• dirty containers that were used for picking apples;
• dirty tools used for pruning or grafting;
• undisinfected premises that were used to store garden tools;
• windy weather (this spreads fungal spores);
• heavy precipitation (fog, snow, rain);
• winter with abundant snow cover;
• cold, long spring.

Symptoms

Fruit rot has an incubation period. About five days pass from the moment of infection to the appearance of the first symptoms, and sporulation begins after 10 days. Actually, after this the tree begins to hurt.

Symptoms of fruit rot:

• first, the formation of the first worm carrion occurs (at summer varieties earlier, for winter ones later);
• the fruit pulp becomes soft and brown;
• the apple begins to rot with a small brown spot;
• this spot gradually increases in size;
• it covers most of the fetus;
• on the surface of a rotting apple in large quantities pads form;
• pads have grey colour and may turn white against the brown color of the apple;
• they are arranged in the form of concentric circles and are the site of conidia formation;
• the fruit becomes black or brown;
• subsequently infection of nearby apples occurs;
• as they ripen, the number of affected fruits increases;
• if the fruit remains hanging on the tree, then the fungus travels along its stalk to the fruit branch, or fruit;
• this causes infection of nearby branches in which the fungus will overwinter;
• in the spring, the infection further spreads into the young ovary;
• wilting, followed by death of overgrowing branches.

Symptoms of a monilial burn:

• flowers become brown or black;
• Over time they dry out;
• then the disease spreads to the ovaries, twigs and fruit branches;
• the leaves on them begin to turn brown and dry out;
• the affected leaves do not fall off and gradually take on a charred black appearance.

How to fight?

This disease is very harmful to the tree, so rot requires consistent treatment.

The main ways to combat moniliosis and prevent it include:

• pruning branches that have dried ends, black leaves and mummified apples;
• burning of cut branches and mummified fruits;
• timely harvesting of apples;
• protection of fruits from various mechanical damages during their removal and transportation;
• storing apples at a temperature of about 0°C;
• mandatory disinfection of storage and containers;
• during growing season various drugs(for example, fungicides);
• spraying should be carried out periodically;
• carry out timely treatment of other diseases;
• treat infectious diseases;
• protection of trees from mechanical damage;
• fight against insects (especially goose, codling moth, sawfly).

The above procedures should be carried out throughout the entire fruitful period, as well as before and after it.

Video “Prevention of fruit rot in apple trees”

Additionally, measures to combat fruit rot can be found in the video below.

Knowing the main reasons for the development of fruit rot, the first symptomatic manifestations, as well as measures to combat it, you can effectively resist this dangerous disease.

Answers Sergey Golovin, phytopathologist, doctor of agriculture. sciences:

Possible diagnosis

—If you carefully examine the photograph from Khabarovsk, you can see that the inflorescences (flowers and stipules) are affected by the burn even before the formation of the ovary. This suggests that the infection occurred in the spring. Healthy, normal leaves that developed after flowering confirm this version.

The entire medical history most likely indicates damage to apple tree flowers by moniliosis (the causative agent is the microscopic fungus Monilia cinerea). According to the literature, monilial burn fruit crops widespread in Primorsky Krai. The disease attacks fruit crops in the spring during flowering.

Treatment

To combat monilial fruit blight, the following protective measures are recommended:

Before the buds open, it is necessary to cut off and destroy all parts of the plant affected in previous years (shrunken flower stalks, twigs, etc.). This is necessary to reduce the infectious background and increase the effectiveness of treatments.

Before buds open, spray with copper-containing fungicides (Bordeaux mixture, copper oxychloride, Abiga-Pik).

After bud break before flowering, spray with fungicides Horus or Fundazol.

After flowering, it is necessary to spray twice with the same fungicides: first with Horus, then with copper-containing preparations from the list above.

What if bacteria?

As for fire blight, this disease of fruit crops, mainly pome trees, is currently widespread in the southern horticultural zones of Russia. This is mainly the Krasnodar Territory, Stavropol Territory and Rostov Region, and there are also reports of this disease from the Tambov and Voronezh regions.

The causative agent of the disease is the bacterium Erwinia amylovora. By the way, it is classified as a plant quarantine object, so suspicion of it requires the intervention of specialists. This infection develops most rapidly at a temperature of about 25 ° C and a humidity of 80-90%.

Unlike moniliosis, bacterial blight of fruits begins, as a rule, after flowering of fruit crops and is most harmful in summer months. This scenario for the development of the disease should be typical for the climatic conditions of the Primorsky and Khabarovsk territories.

Other assumptions

To establish an accurate diagnosis, it is necessary to conduct a study, since it is possible that another causative agent of bacteriosis was at work here - the bacterium Pseudomonas syringae, which can also infect fruit plants in the spring. Therefore, I advise gardeners to contact one of the regional diagnostic centers.

The editors of AiF. At the Dacha" we managed to find out where gardeners from different regions Russia, if the plants at the dacha are seriously ill. Read more in the next issue.

The first time I saw what moniliosis looks like was in 2012. Here, in the Novokubansky district of the Krasnodar Territory, all the apricots, not having time to bloom, dropped their flowers: they stood for several weeks with black, dried tips of the branches - they looked like after a fire. The leaves on the surviving branches blossomed very slowly. Naturally, there were no fruits. What kind of attack is this? This fungal disease moniliosis (monilial burn). It appears during the flowering period on stone fruit crops - apricot, peach, cherry, sweet cherry, plum, felt cherry, quince, grapes, others - at low temperatures, excessive moisture. How to prevent this disease? Is it possible to treat moniliosis?

This is what moniliosis looks like on apricot, photo:

The causative agent of the disease, the fungus Monilia, penetrates through the pistil of a flower and affects young shoots. As a result, the flower part, leaves, and young twigs dry out—a monilial burn occurs.

Flowers of fruit trees are affected by the Monilia fungus at low temperatures - from minus 1.5°C, and the ovary - from minus 0.6°C. I noticed that in Kuban, a drop in temperature in the spring is caused by easterly winds. This year I managed to prevent moniliosis on apricots - I treated apricot trees with the Horus drug as soon as I saw an easterly wind in the weather forecast.

But whether the temperature drops or not, whether the east wind blows or not, the trees must be treated in any case. You shouldn’t hope that it will pass this year. No, it won't! If at least once, at least one tree in your or your neighbor’s tree gets sick with moniliosis - that’s it - spores of the Monilia fungus are already on the branches and trunks of your trees, waiting for suitable weather conditions to develop and destroy the future harvest.

When affected by moniliosis, wilted leaves appear at the tips of the branches:

Very often, novice gardeners do not pay attention to fallen flowers or ovaries, believing that this is due to the fact that the weather has turned bad, and this, they say, is not worth fighting. Of course, changing weather and lowering temperatures are a strong factor. But every gardener should know that it is cold air that creates comfortable conditions for the growth of the Monilia fungus, and, consequently, for the spread of moniliosis. Fallen flowers and ovaries tell you not only about deteriorating weather conditions, but also that you missed the right time to treat your trees against the monilia fungus.

Cherry affected by Monilia fungus, photo:

The picture shows a cherry tree whose branches are affected, but the disease has not yet spread very much. If you notice this on your trees, it is not too late to treat them. Of course, you will lose part of the harvest, but you will still have time to save something. True, this will only succeed if, after a cold night, warm, dry weather sets in and there will be no more rainy cold weather. After all, Monilia is a mushroom that reproduces by spores. IN comfortable conditions- high humidity and low temperature- he will continue his “dirty” work; no amount of processing will help in this case. Alas!

It was necessary to process this cherry during the budding period or, even better, before flowering. By the way, healthy (at first glance) harvested fruits like those in the picture should be quickly processed, because... the fruits will already be infected, the spores of the Monilia fungus are still present on their surface. Such cherries will not be stored! Very quickly you will see that some of the fruits have rotted or begun to rot. This applies not only to cherries, but to other stone fruits too. This is such an insidious thing - moniliosis!

Cherry tree a month after the onset of the disease:

So, under favorable weather conditions, the disease develops very quickly. Heavy rains during the flowering period, fluctuating air temperatures from subzero temperatures at night to positive conditions during the day create ideal conditions for the spread of the causative agent of moniliosis.

For prevention, experts advise treating apricots, cherries, apple trees, and other fruit trees even before flowering with Mikosan-B, Bordeaux mixture, Horus, Skor, etc., then immediately after flowering to prevent moniliosis, and then 1-2 more times with a break of two weeks. The last 1-2 times after removing the fruits. Of course, if the trees are very tall and it is not possible to spray every branch, then at least the trunk and skeletal branches of the tree should be treated. This will increase the tree’s ability to resist moniliosis, the causative agents of fungal diseases.

If you missed the moment necessary to treat the garden against moniliosis, then immediately when they wilt, cut the shoots to healthy leaves and burn them.

For most varieties, timely harvesting is very important, immediately after reaching removable ripeness. When there is overstay, fruit losses from the disease increase sharply.

Moniliosis of plum, photo

But in this picture there is moniliosis of plum. Symptoms of the disease are visible on the fruits. Such plums will not wait to be eaten; they will disappear on the tree. In this case, I was very late in processing the plum tree. Such fruits should all be collected and destroyed - burned. Under no circumstances should you throw them into a compost pit or bury them on your property. Instead of fertilizer, get a breeding ground for the disease.

Gardeners should take into account that moniliosis forms in conditions of high humidity. Monilia fungus spores are carried by wind, raindrops, and insects. That is, if you notice signs of moniliosis only on one tree - an apricot, plum or cherry, this does not mean that only this tree needs to be treated - ALL fruit trees in the garden should be treated.

Currently, breeders have developed many new varieties of fruit crops, but so far there are no completely resistant to moniliosis.

Cherry varieties - Alexa, Kazachka, Kirina, Izanninitsa, Chudo-cherry, Nefris, Effective, Zhukovskaya, are zoned for cultivation in the Kuban, and are moderately resistant to moniliosis.

The zoned plum varieties that are most resistant to the disease are Krasotka, Podruga, Milena, Balkarskaya; introduced - Stanley, Donetskaya, Melitopolskaya, Chachakskaya late, Turchanka.

Improved Caucasian, Sashenka, Yuzhnaya, Poppy, Scarlet, Sorceress, Gift of Abundance, Clear Sun - cherry varieties with average resistance to fungal diseases.

The apricot varieties entered into the State Register for the North Caucasus region, Dzhengutaevsky, Krasnoshcheky, Krasnoshcheky from Nikoloev, Krasnoshcheky late, Kubansky black, Tamasha, Black Velvet, have average resistance to moniliosis.

Conclusion: timely processing antifungal drugs will help prevent moniliosis on fruit trees.
