What are cherry diseases? How to deal with them? Diseases of cherries: symptoms and methods of treatment Brown spotting on cherries.

Cherries in the garden are a special summer delight. From its juicy fruits, unlike cherries, jam is rarely made. But both children and adults enjoy fresh. From one adult tree per season, you can collect up to 80 kg of berries. This can be prevented by diseases and pests that attack cherries. A good gardener should definitely know the methods of preventing and dealing with these problems. Moreover, this is not such a complicated science as it might seem.

Description and features of cherries

Cherry is a tall tree of the Rosaceae family. At favorable conditions it can grow up to 30 m. And this happens quite quickly. Such a large plant has a large root. Most often it is strongly branched underground. The crown of the tree is shaped like a cone or an egg. The bark of the tree has a red-brown color, less often silvery stripes are visible on it. Cherry leaves are small, dark green with a glossy sheen.

Cherry fruits largely depend on the plant variety. In color, they can be from light yellow to almost black. Their taste is very sweet, but the juiciness of the pulp is different.

Unlike cherries, cherries are less whimsical and prone to disease and pest attacks. Although fungi, bacteria and insects can significantly damage the tree and crop.

Sweet cherry bacteriosis

This problem is popularly called cancer or cherry ulcer. It may appear at 4 years of age. A clear sign of sweet cherry bacteriosis is watery spots on leaves and fruits. They are brown or black. During infection, brown ulcers appear on the stalks of the sweet cherry. They can also appear on the kidneys. You can also notice bacteriosis ulcers on the bark of a tree, then gum will flow out of them.

Most often, sweet cherries are affected by bacteriosis during the period of cold and damp spring. It is raindrops that carry bacteria throughout the tree. If the spring is warm and the summer dry, the disease may not reveal itself at all.

Unfortunately, so far, scientists have not been able to invent methods to combat sweet cherry bacteriosis. Disease resistance depends on the type of tree. A gardener can increase the resistance of sweet cherries to harmful bacteria with the help of good nitrogen fertilizer and moderate watering.

Attention! Excess moisture and abundant watering of cherries in case of infection with bacteriosis will lead to the death of the tree.

Fungal diseases of cherries

Cherry is more susceptible to fungal diseases. But, unlike bacteriosis, these lesions are treated.

coccomycosis. This fungus is very dangerous for cherries. On a young tree, it destroys the fruits, and later leads to the death of the plant completely. The first sign of coccomycosis is small brown-red spots on the leaves. If the disease is not fought, they will become more and more. Because of this, the foliage falls by the middle of summer, and the tree experiences severe hunger, as there is no photosynthesis.

To prevent infection of the tree with coccomycosis, it must be treated with a solution blue vitriol or beard mixture. Do this in the spring when the buds swell. The fungus is treated with preparations "Zorus", "Topaz". Treatment is carried out after harvest.

Moniliosis. This fungus is dangerous for all stone fruits in the garden. Signs of the disease: rapid drying of flowers, twisting of leaves, rotting and drying of fruits. Gray growths appear on the cherries. Infection with moniliosis contributes to the complete loss of the crop. It is necessary to deal with moniliosis in a complex way:

  • diseased branches and fruits must be destroyed;
  • you need to remove caterpillars and other insects that carry the fungus;
  • in the fall, you need to process the boles with whitewash;
  • trees need to be treated with copper sulfate, nitrafen, oleocuprite.

Clusterosporiasis. Gardeners know this fungus under the name perforated spot. It affects all parts of the tree. Because of him, pale cherries appear on the cherries. brown spots, bordered in red. After a couple of weeks they become holes. Klyasterosporiosis does not destroy the tree, but significantly weakens it and greatly impoverishes the crop. The fungus is treated with the drug "Horus".

Cherry rot. One of the most common fungi. It is dangerous not only for cherries, but for everyone. fruit trees garden. It appears on the fruits: at first as brown spots, and then a gray mold. The disease is treated with preparations that contain copper (Bordeaux mixture, azophos, copper oxychloride abiga-peak).

Attention! It is impossible to eat cherries affected by gray rot, it can be dangerous to human health.

powdery mildew. This fungus leads to the appearance of a powdery coating on the sweet cherry. It attacks young plants. Because of it, the tree is greatly retarded in growth, and the foliage on it dries out and twists. Powdery mildew is treated with Topaz, Strobe and a solution of potassium permanganate in water.

Cherry pests and their control

  1. Cherry fly. This is the most common and dangerous pest for cherries. The cherry fly lays its eggs in the still unripe fruit, where the larvae then eats away the pulp. Fight the cherry fly with insecticides.
  2. Cherry shoot moth. This insect destroys the buds, leaves and flowers of the cherry. The mole is destroyed at the stage of swelling of the kidneys with the help of the preparations "Holon", "Chlorophos", "Karbofos".
  3. Cherry sawfly. This insect makes whole spider web nests on the tree. Sawfly larvae eat the pulp of the berries. Treatment is carried out with the same drugs as in the fight against shoot moths.

It is noteworthy that sweet cherries are subject to the same diseases and pests as cherries and plums. Therefore, having studied the methods of struggle using the example of sweet cherries, you can take care of a rich and fruitful garden.

Not only beginners, but also experienced gardeners very often there are questions about why cherries do not bear fruit, as well as what main cherry diseases are most dangerous for the plant and threaten the lack of a tasty and healthy harvest.

In any case, the manifestation of signs such as wilting, yellowing or falling leaves, as well as any other changes in appearance leaves require a more detailed examination of the plant, which will help determine the root cause of damage and develop the most effective scheme treatment.

Major diseases and their treatment

Clusterosporiasis or perforation

The causative agent is a fungal infection that can affect not only cherry trees but also plum. The disease is characterized by the appearance on the leaves of rounded light Brown color spots with red-brown or raspberry edging.

A week later, the formation of holes on the leaves is observed, which is accompanied by drying and falling of the foliage. Berries are also affected by the disease and become covered with purple spots that can necrotize the fruit to the bone. Earlier manifestation of the disease may be accompanied by the death of buds and flowers.

Treatment consists in the timely removal and subsequent destruction of the affected parts of the plant. Preventive measures are the prevention of neglect of the crown and spraying of plants after flowering with 1% Bordeaux liquid or preparation "Topsin".

Gommosis or gum disease

The disease most often manifests itself on stone plants that have undergone freezing and fungal infections. The disease is aggravated in conditions of significant waterlogging or excessive fertilization.

The first sign of the disease is the discharge from the stem and shoots of the plant drops of gum, which, when solidified, forms transparent nodules. Such a disease is quite common, and its result may be the death of the plant.

Prevention of the disease consists in observing agricultural practices during cultivation, as well as increasing the immunity of the plant and timely treatment of any damage with the help of a garden pitch. P runs and branches, characterized by a strong defeat, are subject to immediate destruction.

coccomycosis

The disease is the result of damage to the plant by the marsupial fungus Cossomuces hiemalis. The lesion is most often observed on cherry foliage and is characterized by the formation of reddish spots. In conditions of high humidity, a characteristic pinkish bloom appears on the back of the leaves. The foliage first acquires a brown coloration, and then dries out and falls off. The plant weakens and even with slight frosts it can die.

Prevention of the disease consists in the destruction of fallen leaves and timely tillage in early spring, as well as after harvesting. In order to combat coccomycosis, it is recommended to spray three times at the stage of budding, flowering and after harvesting with a solution of copper oxychloride at the rate of 40 g of the drug per bucket of water.

Moniliosis or gray rot

The disease causes browning of shoots and branches of cherries, followed by their withering. Damage to the cortex is characteristic, similar to burns. In addition, the disease causes rotting of the fruit with the formation of small, gray growths, randomly located.

The fight against the disease consists in observing the basic rules of agricultural technology and competently carrying out care measures, including the destruction of affected berries and foliage. Garden plantings should be sprayed immediately after flowering with 1% Bordeaux liquid or solution. "Zineb".

Rust

Fungal infection of most stone fruit and pome garden trees. The fungus infects the foliage of the plant and causes the appearance of peculiar swellings-pads, which have an orange or reddish-brown color, reminiscent of rust.

For treatment, it is necessary to carry out timely collection and destruction of foliage affected by a fungal infection, as well as spraying cherries before the flowering stage with Hom or a solution based on copper oxychloride.

Scab

Belongs to the category of the most common diseases of cherries and sweet cherries in our country. Affected fruits are characterized by the presence of brown spots. Similar spotting appears on the foliage of a plant that has become ill with scab. After a while, the leaves curl up and crumble, and the green berries do not enter the ripening phase and fall off.

The main measures to combat scab are the timely digging of the soil among garden plantations, as well as the collection and subsequent destruction of fallen leaves and berries. A good result is observed when the plants are treated three times with a 1% solution of Bordeaux mixture.

We also suggest that you familiarize yourself with the material of the article, which tells.

Moniliosis or monilial burn

Fungal infection, which is observed on most stone fruits. The main period of the disease falls on the cherry blossom phase. Not only the fruits are affected, but also the wood of the plant. Branches and shoots take on a burnt appearance, which explains the name of the disease - monilial burn. Plants weakened by the disease significantly reduce yields.

Prevention of moniliosis consists in choosing the right place for planting cherry seedlings, protecting plants from mechanical damage and timely implementation sanitary pruning. A good result is shown by processing with a 1% solution of Bordeaux mixture.

root cancer

It is characterized by the appearance of peculiar growths on the site of the root neck and the root system of the tree as a result of damage by soil bacteria. At the stage of the initial stage of the disease, the growths have a grayish-white color. After some time, the growths on the root system become woody.

The rapid development of the disease is facilitated by planting plants on soils with an alkaline environment. The disease is able to stop the growth and development of cherries in a short time.

Treatment consists in cutting off the growths, followed by disinfection of the cut site with a 1% solution of copper sulphate and boric acid. Proper Care for cherries and compliance with agricultural technology reduces the likelihood of developing the disease.

Causes of changes in the state of cherries

It is very important to conduct regular inspections of garden plantings, which allows you to determine the presence of the disease as soon as possible and develop a system for treating and protecting the plant.

Cherry dries

The reasons for this may be:

  • warming of the root neck as a result of significant deepening;
  • damage to garden plantings by such a pest as bark beetle;
  • plant damage by a dangerous disease called moniliosis.

Cherry turns yellow

Cherry yellowing can occur for the following reasons:

  • lack in the soil on which garden plantings are cultivated, nitrogenous substances or boron;
  • fungal infection - coccomycosis or moniliosis;
  • carrying out untimely or incorrect watering;
  • freezing of the plant in winter;
  • the appearance of anthills around the cherry tree.

Cherry falls

Cherries don't bear fruit

Why it happens? The fruiting of a tree can be threatened by the following factors:

  • lack of insect pollinators;
  • wrong choice of varieties for planting;
  • cultivation of garden plantings on too acidic soil;
  • damage by a fungal infection or root cancer.

Cherry crumbles

The main reason is the lack of nutrients in the soil. As a rule, it is enough to apply complex mineral fertilizers or perform foliar feeding to bring the plant back to normal.

Cherry does not bloom

The lack of cherry blossom may indicate the following shortcomings of agricultural technology:

  • the root neck of the plant is too or, conversely, not deep enough into the ground;
  • freezing of flower buds, which is most often characteristic of insufficiently frost-resistant cherry varieties;
  • excessive application of nitrates to the soil.

These situations can be corrected by proper disembarkation seedlings, abundant watering at the stage of active vegetation, as well as top dressing using the preparations "Ovary" or "Bud".

cherry withers

This happens for the following reasons:

Protection from birds and rodents

To ensure the protection of garden plantings from rodents that become active in the winter, special traps should be installed, as well as wrapping cherry tree trunks with a fine mesh.

Competent measures to protect crops from birds are of no small importance. For this purpose, it is advisable to hang special rattles and rustling foil or the usual shiny New Year's "rain" on the branches of the plant. undersized plants can be covered with special nets.

How to cure cherries from diseases (video)

Only strict observance of all preventive measures and agrotechnical requirements will make it possible to create healthy and abundantly fruitful garden plantations that will regularly delight high yields quality berries.

Most varieties of sweet cherries produce only in warm regions, but some modern varieties can form fruits even in middle lane Russia. This culture is not particularly whimsical, but when caring for it, you need not only watering. The gardener must constantly monitor his trees and carry out treatment for diseases and pests at the first sign of their appearance. From our article we will learn why spots appear on cherry leaves, what to do in such a situation.

This fungal disease can affect not only the leaves, but also the buds, as well as the fruits of the culture in question. In the process of defeat sheet plates light brown areas appear on the tree, they increase in size up to 2 centimeters in diameter. After some time, holes form at the site of the spots, the leaves of the culture begin to dry out, and soon fall off.

Preventive actions

To prevent the appearance of klyasterosporiosis on sweet cherries, the gardener must constantly monitor the site and cut out damaged shoots and leaves, as well as dig up the soil in the root zone of the tree. The causative agent of infection usually hibernates in bark cracks, as well as untreated wounds that remain after crop pruning. In this regard, the places of cuts are covered with garden pitch, the crown of the tree is sprayed with a Bordeaux mixture of 3% concentration. last operation should be carried out in early spring before bud break.

How to fight

To prevent damage to the tree by klesterosporiosis, it is necessary to spray the cherry with Bordeaux mixture several times per season:

  • the first time in early spring;
  • the second treatment is carried out after the flowering of the culture;
  • one more no later than three weeks before the expected harvest.

Red-brown spots on cherry leaves (coccomycosis)

Symptoms of the disease in question can be observed during the flowering of the tree. First, numerous reddish dots form on the leaves with a pink coating on inner surface. The affected organs of culture soon begin to turn yellow, dry out and crumble.

Note! Coccomycosis is most common in regions with wet, rainy weather.

Preventive actions

To prevent the development of the disease, it is necessary to constantly collect and destroy the affected fruits, shoots and leaves. These vegetative organs are considered the main source of fungal spores.

How to fight

The main condition for combating the disease is the preventive treatment of wood with a solution. iron sulphate at the rate of 300 grams of active substance per 10 liters of water. After flowering, the sweet cherry is sprayed with the Horus chemical preparation. The treatment of the plant is repeated 3 weeks after flowering and after the same period from the moment of harvesting.

Brown spots or moniliosis

A bacterial burn (moniliosis) can appear on sweet cherries at any time during the entire vegetative period. Affected branches and leaves of the culture acquire a brown tint, soon dry out. The fruits are small, often rot and fall off.

Preventive actions

To prevent the development of the disease, it is necessary to constantly monitor the garden, cut and burn damaged branches and leaves, fruits that have fallen to the ground. In addition, you need to constantly fight pests that can carry the infection. With the advent of autumn, it is necessary to whitewash the boles of all fruit trees.

How to fight

To combat moniliosis, the method of spraying the near-stem circle with a Bordeaux mixture of 1% concentration is used. After the flowering of the culture, the treatment must be repeated.

Brown red and orange spots

The appearance of red and orange patches on the leaves of the sweet cherry tells the gardener that the tree is affected by rust. The fungus quickly spreads throughout the garden, leads to a decrease in the quantity and deterioration of the quality of the crop, premature dropping of leaves.

Preventive actions

For preventive purposes, it is necessary to collect and burn damaged leaves of the crop. With the intensive development of the disease, it is necessary to treat the culture with chemical preparations.

What to do

Before and after flowering, the sweet cherry is sprayed with a solution of copper oxychloride at the rate of 80 grams of the active substance per 10 liters of water. After harvesting, the crown of the tree is treated with a Bordeaux mixture of 1% concentration. Similar procedures are carried out when sweet cherries are affected by white rust. This disease causes desiccation and premature leaf fall.

Brown spots on cherries (phyllosticosis)

Philostiktosis in terms of symptoms and method of treatment resembles klesterosporiosis. During the defeat, round brown spots with a dark rim appear on the leaves of the culture. Black dots can be observed in the center of defective areas. After some time, the affected tissues begin to die, and holes form in their place.

Preventive actions

To prevent further spread of the disease, it is necessary to cut and burn the affected organs, as well as cover the wounds of the plant with garden pitch.

What to do

Use disease-resistant varieties for planting, as well as treat trees with a Bordeaux mixture, in the same way as for clasterosporiosis.

White spots on leaves

Appearance white coating on cherry leaves associated with powdery mildew. This disease only affects young seedlings, leading to stunted growth and premature death of leaves on trees.

What to do

There are many chemicals to combat this disease, such as Strobi, Topaz or Phytodoctor. Some gardeners use a 2% concentration colloidal sulfur solution or a lime-sulfur decoction with the same amount of active substance for processing. In this case, spraying is repeated every two weeks.

To prevent the development of any of the diseases, whitewash stone fruit strains in spring and autumn, rake and burn fallen leaves. Treat with the arrival of spring fruit trees Bordeaux mixture.

Video

Common cherry diseases often lead to the complete death of a bush or tree of this stone fruit crop. If you read the description of cherry diseases, you can easily guess that similar symptoms are also inherent in cherries, plums and apricots. The diseases of cherries and sweet cherries presented in this material can be easily prevented if signs of their development are noticed in a timely manner. Most often there is a threat of fungal infection, bacterial diseases are less common.

Viral lesions of the trunk, branches and leaf blade of a tree can develop under adverse conditions. weather conditions. The main diseases are presented on this page. Here you can find full descriptions symptoms and pathological changes, see them on the accompanying images. It also tells about the available measures to combat them using simple and affordable means.

The main causes of cherry disease

The health of cherries primarily depends on proper care for them. Compliance with all the rules of agricultural technology (timely watering, top dressing, pruning) significantly increases the immunity of trees, and minimizes the likelihood of them being affected by diseases.

There are other factors that affect the degree of damage to cherries by diseases:

  • Climatic conditions of the region;
  • Weather conditions (temperature fluctuations, dry summers or high humidity, frosty and snowless winters);
  • Mechanical injuries of branches or bark surface;
  • Pests carrying bacteria;
  • Diseases of other trees growing nearby.

By establishing the causes of the disease of cherries and cherries and eliminating them, if the gardener can do it, it will be much easier to deal with the disease.

Coccomycosis: a description of the cherry disease with photos

Cause the most damage to crops fungal diseases cherries. One of the most dangerous and insidious is coccomycosis. The spread of the disease is facilitated by long wet periods when the air is warmed up to 20–24 °C. Such conditions contribute to the fact that the causative agent of infection, the fungus Coccomyces hiemalis, develops unhindered, multiplies and infects plants. The disease manifests itself in the summer, and its characteristics, primarily visible on the foliage:

  • Rounded brownish or reddish spots form on the front side of the leaf plates.
  • Gradually, they grow, the tissues in the middle dry out, and areas with a pinkish bloom appear on the back of the leaf.
  • The foliage affected by coccomycosis dies off and falls off in the second half of summer, leaving the branches almost bare.

Judging only by external signs, coccomycosis could be considered a disease of cherry leaves. But this opinion is wrong! Due to the early loss of the green part of the crown, cherry trees are weakened and unprepared for wintering. As a result, some of the shoots die by spring, damage is found on the trunk and skeletal branches.

Already in the first year after infection, the cherry reduces the yield, the quality of pilaf decreases. If you do not urgently deal with the fight against the disease, the cherry, as in the photo, dies in the next few years.

Premature leaf fall in the middle of summer should seriously alert the gardener. All fallen leaves must be collected and destroyed, and the plants are treated with Bordeaux liquid, a solution of ferrous sulfate or systemic fungicides. Re-processing is carried out according to the instructions after 7-14 days after the first one.

The main measures to combat the fungal disease of cherries are aimed at destroying the pathogen and preventing its spread to healthy trees.

As a preventive measure in the risk zone, as well as in wet weather that contributes to the spread of coccomycosis, spraying of cherries is carried out in the spring, even before opening. flower buds, and at the end of the mass flowering of plants.

At the same time, one must be aware of the possible toxicity of sprayed products. The fruits remaining on the branches are removed, hands, respiratory organs are protected with gloves and a respirator. In order for the action of the drugs to be as effective as possible, they must fall on dry foliage and act unhindered for 2-3 hours. Therefore, for processing, it is better to choose a calm, fine morning or evening when there is no danger. sunburn.

Moniliosis: description of cherry disease with photos

This disease is referred to as monilial burn. The fungus infects the branches and leaves of the cherry tree in such a way that they look as if they were burnt. The disease spreads, thanks to the wind, moving from a diseased tree to a healthy one.

The infection loves cool weather and perfectly retains its pathogenic abilities even when severe frosts. So, moniliosis, as it progresses, affects flowers, leaves, branches and cherry bark.

Reasons for the appearance

The appearance of the fungus occurs spontaneously. So, your cherry trees can "burn out" due to the disease of trees growing in neighboring areas.

signs

The manifestation of the fungus moniliosis is difficult to confuse with anything else. The disease looks like this:

1. There is a wilting of buds, young branches.

2. Wood looks burnt.

3. The bark of the cherry begins to become covered with growths of gray.

4. Dense growths begin to appear on the fruits.

5. Cracks form on large branches.

6. Cherry berries dry out and fall off.

Treatment

Treatment in the form of sprays in the case of moniliosis is not enough. Since the fungus tolerates winter well, transferring low temperatures, then it is extremely important to get rid of it completely.

To do this, you need to remove all the affected parts of the tree, carefully removing all the branches with an additional grip of 10 centimeters. All affected fruits and branches must be burned.

In the spring, just before bud break, the trees and the soil around them should be sprayed with 3% ferrous sulfate 300 grams per 10 liters of water. Prevention of the disease consists in the fight against pests and the reappearance of the fungus.

Also, it is extremely important to carefully harvest, avoiding breakage of branches. Only such methods of treatment and timely prevention can save the tree.

Clasterosporiosis: a description of the cherry disease with photographs

Clasterosporiasis, like other cherry diseases, is harmful to leaves, fruits and other above-ground organs of the tree. In order to counter each of the diseases, first of all, a visual analysis should be carried out, a guide to which will be viewing the cherry disease in pictures. Leaves affected by clasterosporiasis are easily recognizable by small reddish-brown spots (1-2 mm), the tissues of which die off and holes with a red border form in places. It is the red border that distinguishes clasterosporiasis from other types of spotting.

At the middle stage of development, this disease covers the fruits, turning them into shriveled balls that actively fall from the tree. The incubation period of clasterosporiasis is from two to four days. Treatment of this disease is a series of the following actions:

  1. In autumn, before the start of leaf fall, when the sores can still be visually seen, cherry pruning is carried out, all affected branches and foliage are removed and burned. Only this technique alone can protect against the spread of the disease and survive the winter well;
  2. Immediately after pruning, spray the trees with a 3% solution of Bordeaux mixture.
  3. In the affected areas, the bad bark must be scraped off in such a way as to capture another 2 cm of the healthy one. Then disinfect with copper sulphate (1%) and cover with garden pitch.

Anthracnose: a description of the cherry disease with photos

Anthracnose cherry - main enemy for berries not only cherries, but also cherries. Anthracnose-infected cherries lose their flavor, turning into rot that hangs loosely on the stem. The manifestation of anthracnose can be detected by dark spots that turn into tubercles and a pinkish coating forms in the affected areas. The disease loves dampness and warmth, therefore, in rainy summers, absolute decay of a large number of cherry fruits is often noticed.

Cherry diseases are a great danger to the crop and the tree as a whole, therefore it is imperative to fight against anthracnose:

  • Prevention in the form of whitewashing the trunk and cherry branches with whitening mixtures, as well as timely harvesting of fallen fruits and digging the soil around the trunk;
  • Treatment of affected shoots with garden pitch;
  • Application of Polyram for spraying (20g/10l of water), before flowering, after and 10-15 days after the last spraying;
  • In addition, the use of Bordeaux liquid (1%) will also be effective both in spring and autumn.

Cherry rust: description of cherry disease with photos

Symptoms:

When infected, cherry disease manifests itself in the form of red spots and tubercles on the leaves with an orange border, outwardly similar to metal rust.

Treatment and prevention of rust

To avoid rust on cherries and cherries, do not plant them near coniferous plants. It is also worth taking out of the site and burning all fallen leaves and carrying out preventive spraying of trees with copper sulphate in the fall.

Treatment of the developed disease is carried out systemic copper-containing preparations: HOM, Skor, Topsin-M. The trees are treated twice with an interval of 14 days, after removing all the affected leaves.

Cherry stem rot, tinder fungus flat: description of cherry disease with photos

The causative agent is the fungus Ganoderma applanatum (Pers. et Wallr.) Pat. Causes a yellowish-white wood rot that breaks trees easily. Infection occurs from the root neck at the base of the bole, from where the mycelium spreads upward along the core of the trunk. Fruiting bodies are perennial, flat, sessile, often tiled, with a grayish-brown furrowed upper surface, smooth or covered with brown bloom. The flat tinder fungus affects deciduous tree species, pome and stone fruit crops, and more often settles on weakened trees. The infection persists in the affected wood.

Control measures. Annual preventive spraying of trees in the spring, before the leaves bloom, with a 1% Bordeaux mixture or its substitutes (HOM, Abiga-Peak). Timely removal and burning of stumps and dried trees along with their roots. Single fruiting bodies on the affected trees are cut, the saw cut is disinfected with a 1% solution of copper sulphate and covered with oil paint on natural drying oil.

Gommosis: a description of the cherry disease with photos

Gommosis or gum disease is often found in stone fruit trees, especially cherries and plums. The disease occurs on the bark, branches and fruits of cherries. When the branches are damaged, the cambium is disturbed and further growth in thickness becomes impossible. Another danger is that the fungus moniliosis spreads with the gum, which is transferred to healthy trees with the help of the wind.

Causes of gommosis:

  • excessive watering and fertilization;
  • early kidney loss;
  • frost holes and other branch injuries;
  • some pests can also cause gum disease.

To prevent gommosis of cherries, follow agricultural practices:

  1. Do not over-moisten the soil with frequent watering.
  2. Apply fertilizers according to the instructions, do not overdose.
  3. Prune frost-damaged branches promptly.
  4. Protect the tree from sunburn.

Treatment consists in the treatment of wounds resulting from gum treatment. Suitable for this garden var, 1% solution of copper sulphate (10g/liter). Extensive wounds can be covered with a mixture of cow dung and clay in a 1: 1 ratio.

Scab: description of cherry disease with photos

A fungal disease that damages the leaves and fruits of cherries.

  • Signs. After the defeat of the cherry by the spores of the pathogen, brown-olive spots with a velvety surface appear on the leaves. Yellow circles are blurring around the spot. Gradually, the spores of the fungus pass to the fruits, cracks form on them. Unripe green fruits stop developing.
  • Treatment. Spraying cherries and the near-stem circle with Nitrafen before buds open. After that, you need to do three treatments with 1% Bordeaux liquid: during bud break, after flowering, after harvest. If necessary, repeat the procedure.
  • Consequences. Harvest loss.

Root Cancer: Description of Cherry Disease with Photos

This is a bacterial infection of the roots that appears through infected soil.

Signs. The appearance on the root neck, main and lateral roots of tumor growths - galls. At the beginning of the disease, the growths are small, soft and with a smooth surface. As the disease progresses, they increase in size, acquire a hard and bumpy surface. In autumn, the growths are destroyed.

Treatment. Two treatments of cherries with a 3% solution of ferrous sulfate: before and after the growing season.

Consequences. Plant nutrition deficiency, impaired sap flow, reduced productivity and disease resistance.

A thorough inspection is required before boarding. planting material. If tumor-like growths are found, the affected areas are cut to healthy tissue, the roots are treated with a 1% solution of copper sulphate.
