Having safely planted a cherry seedling on the site, and already looking forward to a rich harvest in the future, you should not forget that cherry diseases and their treatment are quite a common occurrence that you will most likely have to face sooner or later. It is almost impossible to protect cherries from all diseases and pests, because their distribution is affected not only by agricultural technology, but also by weather patterns, accidental damage to branches and other unpredictable factors.
Therefore, you must not only take the time preventive measures, but also regularly inspect the trees, so that at the first sign of cherry disease or insect damage, start treating the tree. And before planting a cherry, check if you are going to use the scion from a diseased tree?
Below are diseases and pests of cherries that can cause great damage to the berry crop, and to the trees themselves. special attention deserve such dangerous fungal diseases as coccomycosis, leading to premature leaf fall, and cherry moniliosis, from which the berries rot and mummify. It is impossible to fight these diseases without spraying trees with fungicides, so it is better to initially plant cherry varieties that are resistant to moniliosis and coccomycosis.
It is almost impossible to protect cherries from all diseases and pests.
Video about cherry diseases
The fungus primarily affects cherry leaves, appearing on them in the form of brownish red dots that turn into spots. On the underside of the leaves, you can see the spores of the fungus in the form of a white-pink bloom. Soon after infection, the leaves fall off, as a result, the cherry leaves unprepared for frost in the winter. For several seasons, the tree completely weakens and dies in one of the frosty winters. Cherry coccomycosis can also affect the fruits - in this case, they are deformed and become unfit for food.
The causative agent of coccomycosis for wintering is hidden in fallen leaves, and therefore, first of all, it is necessary to immediately destroy all plant residues under the tree, digging up the soil in spring and autumn. In the spring, the first spraying is carried out on the blossoming leaves with Bordeaux liquid (3%). The second time the treatment is carried out immediately after the flowers fall off with copper oxychloride (0.4%), or Topsin-M solution (0.1%), the drug Skor is also effective. The third time the cherries are sprayed with Bordeaux liquid (1%), or copper oxychloride (0.4%) after harvest. Additionally, you can treat cherries with Skor even before flowering.
Cherry coccomycosis
It is no coincidence that the disease is called a monilial burn, because the affected branches and leaves of the cherry look like they were burned. As the fungal disease develops, the bark of the tree becomes covered with small growths of a gray hue, the same growths appear in a chaotic manner on the fruits, causing them to rot. Cracks form on old affected branches, gum protrudes, and gradually the branches die. Most of berries are mummified and fall off, some berries can sag until spring.
Since the fungus overwinters in the affected parts of the plants, it is very important to regularly remove and burn all the affected fruits, and cut the branches, capturing healthy tissue by 10 cm. Before the fresh buds bloom, the cherry and the soil around it are sprayed with Bordeaux liquid or iron vitriol 3%. Copper sulphate, nitrafen and oleocuprite are also suitable for processing. You can also spray the trees after flowering using 1% Bordeaux mixture or fungicides (phthalan, cuprosan, cineb, captan). It is important to regularly carry out preventive pest control and try to harvest as carefully as possible so as not to damage the cherries.
Moniliosis in cherries
With high humidity in warm weather, brown spots with a dark border may appear on cherry leaves, instead of which through holes. Spots of red-brown color also appear on the fruits, due to which the shape of the cherries is deformed and the fruits dry out. The bark on the shoots cracks, gum is released from it.
The mushroom picker hibernates on branches and annual growths of cherries, and therefore diseased branches must be cut out, and cracks with gum disease should be carefully cleaned and treated with garden pitch. Fallen fruits and leaves are cleaned and burned. Spraying is carried out in the same way as with moniliosis.
Increasingly, anthracnose is found on cherry trees, which mainly affects the fruits. At first, dull spots form on the cherries, after which small tubercles form and a pinkish coating appears. In dry weather, cherries begin to dry out, mummifying in the sun. If the summer is wet, rainy, anthracnose can destroy up to 80% of the crop.
Gray rot at the cherry
It helps to cope with anthracnose by spraying cherries three times with the chemical preparation Polyram: before the flowers appear, immediately after they wither and two weeks later. All diseased fruit should be collected and destroyed immediately.
Damage to cherries with perforated spotting, moniliosis, sunburn or frost often leads to such a disease as cherry gum disease. Isolation of transparent hardening drops, gums from the branches and trunk, is also possible with excessive fertilization or watering of the soil. Seemingly harmless at first glance, cherry gum can eventually lead to the complete death of a tree.
In order to prevent gum disease, cherries must be carefully looked after, protecting them from diseases with preventive treatment with copper sulphate, and from sunburn and frost damage - with the help of whitewashing with lime. Thoroughly clean any wounds that appear on the cherry and cover it immediately with garden pitch or petralatum. Those branches that have already been badly damaged should be destroyed.
Cherry care video
Insects can leave you without a cherry crop with no less success than the listed diseases. Therefore, be sure to take the time to inspect the trees in order to identify pests. What the main pests of cherries look like, you can look at the pictures on the Internet, here you will find out what harm they cause to cherries, and how you can get rid of them.
Fruit damage by cherry weevil
Any gardener takes care of his trees and worries when cherry diseases occur. Sometimes, regardless of proper care, trees are affected by serious diseases or pests. Cherries can be subject to such problems, so you need to know how to get rid of them.
In order to identify the disease, it is necessary to conduct a daily inspection of the trees. Because very often diseases and pests affect the crown, trunk, leaves, even berries. It is much easier to avoid such a problem than to deal with it later.
Be sure to constantly carry out prevention in your garden or garden. Used for this as medications, as well as methods traditional medicine. Each medicine for a tree must be used strictly following the instructions, otherwise you can simply destroy the tree.
There are a wide variety of cherry diseases. Sooner or later, any gardener will encounter them.
Diseases in cherries can occur from both fungi and bacteria. Each requires a specific approach.
The fight against diseases requires the need to constantly cut branches, rotten berries and leaves; constantly fight pests, such as caterpillars or codling moths; harvest carefully so as not to damage the berries.
Advice. In the fight against this disease, you need to quickly resort to help. chemicals such as Topaz. So that the product does not wash off with rain, it must be mixed with laundry soap. Processing should be carried out after the color of the tree.
For the fight, the removal of diseased branches or berries is used. Then it is necessary to treat with a chemical solution Horus. Treatment with copper sulphate or Nitrofen is also ideal. A folk remedy is a decoction of sorrel, which must be insisted and treated with a tree.
It is necessary to fight such an ailment from the spring. Those berries that have been damaged by hail or strong winds are affected. All spoiled fruits must be removed.
powdery mildew
- this cherry disease must be feared when planting, because tree seedlings are affected. When this disease appears, the tree grows slowly, the leaves crumble.
Advice. In the fight against this disease, chemical solutions such as Topaz or Strobi should be used.
Cytosporosis - differs in the defeat of the stem, shoots of a tree, very rarely even the roots can suffer. When this disease appears, all young trees die. The bark becomes brittle, acquires a brown color. By spring, the tree is completely dry.
To prevent this disease, it is necessary not to allow various insects to corrode the bark. Pruning should be carried out very carefully, without damaging the tree.
In this case, it is necessary to burn the damaged foliage. Treat the tree with Bordeaux liquid, nitrafen, blue vitriol. If the infection is very strong, treat it again in the fall.
Important! Do not forget that processing, especially with chemicals, must be done following safety precautions. Be sure to use gloves, a mask and goggles. Never inhale chemicals.
In order to completely get rid of the fungus, it is necessary to burn all the foliage, remove rotten berries, and dig up the ground.
It is difficult to overcome such a disease. You will have to completely get rid of the tree by burning. Or constantly remove emerging growths. Then clean the bark, treat with vitriol.
In the spring, you need to feed the tree. Be sure to whitewash the trunk. If, nevertheless, cracks from frost appeared on the bark, then you need to clean them, then process and cover them up.
To avoid such a manifestation, it is necessary to protect the tree from frost in winter, properly insulate it, fertilize it. Frost cracks must be cleaned and treated.
In order to avoid it is necessary to get rid of infected leaves and fruits, to produce constant spraying.
In addition to fungal diseases, there are such diseases:
It can be avoided by good watering.
It is impossible to get rid of such a disease. It is necessary to burn the trees and treat the soil with potassium permanganate.
Disease is not the only thing that can ruin a crop. These are cherry pests.
It is very important to get rid of unexpected guests, otherwise, in just an hour, the harvest of “bird cherries” will disappear from the garden. It is necessary to install various scarers on trees and in the garden: stuffed animals, mirrors, garlands - everything that will scare away birds. But this is a temporary salvation, the birds will return. Only a fine mesh thrown over a tree can really help.
cherry aphid
- This is a black, shiny pest. Their eggs remain on young shoots. In spring, they hatch, while occupying the tops, leaves and pedicels, from where they suck out all the juice. The leaves turn black, dry and crumble. In order to get rid of this pest, you need to use a decoction tree resin. It is also great to use pesticides. Spraying should be done immediately after the appearance of the first insects.
cherry shoot moth - This is a very small pest that is difficult to find on a tree. It hibernates in the bark. Due to the appearance of this pest, the tree grows slowly and slowly dies.
In order to avoid the cherry moth, you need to dig up the soil, pull out all the caterpillars. Then treat with Karbofos and Spark solution.
cherry fly - is found in absolutely all regions and can destroy almost the entire crop.
For prevention, it is necessary to bury all spoiled berries deeply. You also need to distract the flies with sweet ribbons so that they do not reach the sweet cherry. Still need to be treated with insecticides.
Weevil
– little pest which is considered very dangerous. It eats away the bud, which leads to damage to the berry. To avoid the consequences, it is necessary to dig up the soil in the fall, get rid of rotten fruits, and fertilize in time. Be sure to collect bugs and burn them. Should be treated with an insecticide.
winter moth - This is a pest that flies from the forest. These are yellow-green caterpillars that feed on both leaves and other parts of the cherry. Most importantly, butterflies appear from them, which are resistant to frost.
In autumn, it is advisable to dig up the soil in order to get rid of butterflies and caterpillars, the bark must be cleaned of moss.
Every garden must be protected from any influence of pests or diseases. It is best to carry out preventive measures in the garden, then there will be no need to fight diseases or pests. It is impossible to feel sorry for already dying trees; if necessary, it is necessary to uproot them and burn them. Otherwise, you risk healthy cherries and cherries.
For many gardeners, cherry diseases and the fight against them become a big problem, because the treatment does not help, the drugs are not effective, the tree withers, the leaves turn yellow, the bark bursts and the plant dies.
Coccomycosis, clasterosporiasis, verticillium wilt, chlorosis, gommosis, cancer and other sores must, first of all, be able to identify and only then begin to act.
Unfortunately, it is not always possible to save a tree, even if you are a great gardener...
Cherry diseases and their control are of great difficulty for gardeners.
With the wrong approach to treatment, you can lose not only the crop of the current year, but also the tree itself.
Therefore, it is important to understand what kind of disease the cherry tree suffers from. Particularly common fungal diseases stone fruits:
The fungus primarily affects the leaves, brownish spots first cover the surface, and then corrode the leaf tissue, dotting it with small holes. Therefore, klyasterosporiosis has a second name - perforated spotting of sweet cherries. Branches, buds, flowers are also susceptible to fungal attack.
Klyasterosporioz cherries - on the photo
How to fight? Remove diseased leaves, regularly dig up the soil around the trunk. Treat all damage to the bark with 1% copper sulphate. At the beginning of the season, before the foliage appears, treat the tree and the ground around it again.
As soon as the kidneys begin to open, treat with Bordeaux liquid at the rate of 100 g of the substance per bucket of water. The second time, spray the crown after flowering, the third - after another couple of weeks, and the fourth - after harvesting the berries.
This disease is also called reddish-brown spotting, the leaves during the flowering period are covered with red dots, and pink pollen is visible on their underside, the foliage turns yellow and crumbles.
Cherry coccomycosis - pictured
How to fight? Before blooming, treat the crown with iron sulfate (300 g per bucket of water), and after flowering, spray with Horus (2 g per bucket of water).
Repeat the Horus treatment after two to three weeks, and spray again at the end of the harvest. Plant varieties on the plot that are more resistant to coccomycosis, such as Fatezh sweet cherries.
And, here, sweet cherries Valery Chkalov are not very resistant to disease, but the fruits are very tasty.
Moniliosis, or gray rot
The manifestation of gray rot on cherries outwardly looks like a burn of leaves - they darken and dry out, as if scorched. The monilial burn also affects the fruits of the cherry, grayish growths appear on them, the berries rot and fall off.
Cherry moniliosis - in the photo gray rot of cherries - in the photo
How to fight? Diseased tissue should be removed and burned. Harmful insects- caterpillars and weevils - carry the fungus, so they also need to be fought with insecticides.
In the spring, and also at the end of flowering, spray the trees and the ground around them with 1% Bordeaux liquid, after flowering, repeat the disinfection.
For disinfection, trees are also whitewashed in the fall.
Verticillosis, verticillium wilt of sweet cherry, wilt
The names of the fungal disease that manifests itself in early spring usually on young trees. If the bark on the cherry bursts, most likely it is verticillium.
Flowers darken and fade, gum appears on the branches and trunk, the bark exfoliates, and tissue necrosis occurs. The younger the tree, the faster the disease progresses.
The death of a plant younger than seven years old can occur in a year, older ones - in three to eight years.
verticillium wilt of sweet cherry - pictured
How to fight? Try not to damage the roots when digging, as the fungus enters the wound from the soil and rises through the capillary vessels. In the spring, before the leaves appear, spray the crowns with cuproxate or 3% Bordeaux liquid.
And when the foliage blooms, treat with a 1% solution a few more times: after flowering, after a couple of weeks, then at the end of summer and for the last time in October, before leaf fall begins. If the infection does not give up, use stronger drugs against verticillium wilt - Polycarbacin, Fundazol, Topsin, Vectra, polychrome.
gum on cherries - pictured
Carefully clean the cracks from which the gum flows and cover with mullein and clay mixed with 2% copper sulphate.
Cover stumps from cut diseased branches with garden pitch or oil paint.
Often verticillium wilt occurs in sunny and frosty areas, so in the fall, whitewash the trunks with a solution of lime with the addition of blue vitriol.
Fungal diseases of sweet cherry and the fight against them are not limited to the above options, they also include phyllosticosis - brown spot, powdery mildew, scab, cylindrosporiosis - white rust, most of which can be dealt with with fungicides. Real mushrooms also settle on the trunk of a cherry tree - sulfur-yellow tinder fungus, false tinder fungus. To prevent their occurrence, eliminate all damage to the bark in time.
If a cherry seedling dries up, it is possible that it is sick with bacteriosis, this is very dangerous. bacterial disease, usually affecting young cherry trees from three to eight years.
sweet cherry bacteriosis - on the photo
Bacteria are carried by airborne droplets, settle in tree buds and penetrate into the vessels of the plant. The bark is covered with ulcers from which gum flows. Fruits and leaves become mottled and die off. The cold spring contributes to the activation of the disease.
How to fight? Unfortunately, effective methods of combating bacteriosis have not been developed. But, warm dry weather hinders its development.
Nitrogen fertilizers strengthen plants and increase disease resistance. In addition, at different varieties cherries, the degree of resistance to the disease varies.
Sweet cherries, the health benefits and harms of which are not known to everyone, require proper care to get tasty and juicy berries.
Gommosis, or gum disease, is observed not only in cherries, but in all stone fruit trees. On trunks and branches, even on fruits and foliage, there are often streaks of a thick, viscous substance similar to resin - gum.
Gum cherries - on the photo
Excessive release of gum indicates a problem with the plant.
The reasons can be different: injuries, frost damage, excess nitrogen fertilizers, fungal diseases and pests, treatment with growth regulators and phytohormones. Therefore, it is necessary to find out what caused the excessive release of gum.
How to fight? The wood in the place where the gum is released should be cut to a healthy layer, and then treat the wound with copper sulphate and cover it with garden pitch.
Cherry chlorosis - many trees growing on land saturated with chalk and limestone fall ill with chlorosis. Proximity ground water also causes chlorosis. Plants do not receive enough minerals and synthesize chlorophyll poorly.
This can lead to a delay in their development, deterioration in fruiting, a decrease in productivity and even death. Sweet cherries are largely prone to chlorosis. If you notice that the leaves are lightening, especially in young specimens, this may be a sign of illness.
How to fight? Treatment of chlorosis is associated primarily with ensuring the functioning of the root system.
Oxygen exchange in the roots is improved by potassium permanganate, a tree is watered with a solution in the proportion of 30 g per bucket of water, the soil under which is previously moistened and loosened.
Fresh manure, superphosphate, excess potassium fertilizers contribute to the development of chlorosis. It is useful to apply nitrogen fertilizers.
Reduces chlorosis by adding compost, humus, peat to the soil. Two or three times a year, you can make them in the amount of 5 kg per square meter.
In early spring, before the leaves appear, spray the trees with iron sulfate in a proportion of 300 grams per bucket of water.
Later, at the beginning of summer, also carry out two or three treatments with an interval of 10 days, but at a lower concentration, 50 g per bucket of water is enough.
Make sure the solution does not burn the leaves. If this happens, dilute the solution.
In autumn, bring iron sulfate under the trees, mixing it with earth, humus or compost, then water the tree trunks abundantly. Now you know what are the main diseases of the sweet cherry and the fight against them. Like any disease, it is always easier to prevent than to get rid of them.

Foreword
Our article will tell you about the main diseases of sweet cherries and their treatment, which will make your garden healthier and grow a rich harvest. Read the tips carefully and follow them to win the fight.
Unfortunately, proper fit and caring for cherries do not guarantee you a harvest. After all, these garden trees can be seriously damaged various diseases or pests. Why are cherries sick? Let's analyze the main reasons:
sick cherry
By the way, the degree of susceptibility to disease also depends on the selected variety.
That is why it is better to buy seedlings of varieties that are resistant to diseases, bacteria and adapted specifically for your climate zone.
Undoubtedly, such seedlings will cost more, but in the future everything will pay off, because you will save a lot of money and time on treatment.
To protect the cherry orchard from diseases, learn to accurately identify their symptoms and choose the right treatment. It is better to start with brown rot, which is most often found in domestic open spaces.
It is not difficult to determine it: on the leaves appear dark spots brown or maroon, inside leaves form black dots. The affected parts of the tree dry very quickly and fall off.
Bordeaux liquid for disease control
Trees need to be treated with Bordeaux liquid, which you can easily prepare yourself. Take 100 g of slaked lime and mix in 5 liters of water.
In another container, mix water and copper sulfate in the same proportions. After that, carefully and slowly pour the contents of the second container into the first and stir gently.
By the way, the same remedy perfectly fights another disease dangerous for cherries - fruit rot.
The symptoms here will be somewhat different: dark spots first appear on the berries, and literally a week later the disease affects the entire cherry, turning the pulp into an inedible and watery puree.
Klesterosporiosis can also cause serious damage to trees. This disease is determined by round spots with a dark red border on the leaves.
After just two weeks, holes begin to appear in their place, after which the leaves dry out and fall off. The same marks appear on the berries, which dry out quickly.
First of all, take care of prevention. To do this, treat your garden with a solution of copper sulfate (1%) in early spring. If the signs of the disease have already shown themselves, treat the trees with Nitrofen.
At the same time, remember that it is impossible to spray during the flowering period and 20 days before picking berries.
There is one folk remedy in the fight against clasterosporiasis: pour a kilogram of finely chopped sorrel with a liter of water, let the mixture brew for several hours, and then carry out the treatment.
If yellowish stripes appear on the leaves of the cherry, your tree is struck by a disease such as mosaic ringing.
It causes serious damage to plants, because at first the leaves turn yellow and fall off due to the disease, and after that the tree itself begins to slow down in growth.
The problem is that on this moment there is no effective remedy against this disease - the affected trees will have to be removed from the site and burned. If there were trees in the garden that were previously affected by mosaic ringing, be sure to disinfect the soil with potassium permanganate.
Verticillium wilt is a very dangerous disease for cherries. It manifests itself in the fact that very few buds and buds develop on the tree, and even having blossomed, the buds wither in just two weeks, and the cherry itself ceases to bear fruit.
To reduce the risk of disease, choose the right place to plant a seedling: away from garden strawberries and nightshade (tomatoes, peppers, potatoes). Also don't forget to root dressing aqueous solution urea.
If it is not at hand, replace it with wood ash - 1 kg of ash is enough for 2 trees.
But not only diseases can cause crop loss. Cherries, like many other fruit trees, are very fond of various insect pests. Let's start with the cherry shoot moth.
The problem is that this insect is very small - it reaches a length of about 5 mm, so it is quite difficult to notice the mole. The pest survives the winter in the bark of the tree, and in early spring it begins to feed on the buds, causing their rapid death.
With the growth of the moth, the damage caused to the tree also increases: the caterpillars feed on the shoots of the plant, as a result of which the tree begins to bear fruit more slowly.
cherry shoot moth
To get rid of this pest, you need:
Such a pest as the cherry fly lives in the southern gardens.
True, as a result of climate change, the cherry fly is now increasingly found in the northern regions, so this information will be useful to all gardeners.
Under favorable conditions, this pest is capable of destroying almost 90% of the cherry crop and 50% of the cherry. At the same time, he eats only healthy berries, bypassing underdeveloped and rotten ones.
To deal with cherry fly, follow our instructions:
Another enemy of the sweet cherry is the weevil, a small but very dangerous pest. The larvae can eat up to 50% of the crop. Adult beetles eat out the buds and the pistils and stamens located in them, which leads to damage to the fruit. To fence your garden from this insect, you should:
Winter moth can also bring a lot of grief to gardeners. This pest is especially dangerous for those whose dachas are located near the forest, from where the insect flies.
It is easy to identify the moth - these are small yellow-green caterpillars that appear on the site about two weeks before the plant begins to bloom. They feed not only on leaves, but also on other parts of the cherry.
In August, the caterpillars move into the ground and pupate, and already in September, butterflies appear, for which frosts down to -15 ° C are not terrible.
The fight against moth includes several steps:
You need to start fighting pests even before they attack your garden. This will minimize the risk of tree damage. At the very beginning of April, it is imperative to treat the trees and the root zone with a solution of urea.
This will destroy the pests wintering in the ground. The solution is prepared very simply: mix 0.7 kg of urea for every 10 liters of water. It should not be processed later with this composition, since there are high chances to burn the buds and ovaries of the cherry.
Prepared urea solution
In the spring, every 25–30 days, you should additionally spray the garden with preparations that will help scare away flying insects from cherries.
The most effective include Iskra-Bio and Fitoverm, when using, you should strictly follow all the recommendations indicated on the package. To protect against pests, the object of which are the leaves, you should choose the drug Hom.
Dissolve the package of product in a 10-liter bucket of water and spray the tree. In this case, the product should be used during flowering and after picking berries. In early spring, you can wash the bark of a tree with a solution of iron sulfate.
And so that the liquid does not drain and better stick to the bark, you can add a couple of drops of ordinary glue to the mixture.

Grow healthier tree cherries are not easy. Cherry diseases with photos and the fight against them is the topic of the article. A tree gets sick when it is weakened by improper care, malnutrition.
Due to early fruiting, diseases rarely take the crop.
If you do not maintain a systemic protection of the garden, ailments take root deeper, the cherry loses its strength and it is no longer possible to save the crop - you will have to fight for the life of the tree.
All cherry diseases are divided by distribution:
Prevention measures, ridding the garden of pests, and careful attention to each damaged leaf will help keep the sweet cherry healthy.
A photo will help to recognize cherry diseases and fight them. Hole spotting is the most common cherry disease. The disease covers the entire plant, but begins with brown spots on the leaves. The mycelium and spores overwinter in the bark and on the branches.
To localize the disease at the first sign, branches with diseased leaves are cut off, the wounds are treated with sorrel juice three times in 10 minutes, and covered with garden pitch. Preventive treatments in the spring with copper sulphate - blue spraying. The first treatment with nitrofen gives the best result.
Brown spotting - phyllosticosis is manifested by round spots with necrotic lunges. On both sides of the spot, black dots are visible - conidia. With a developed disease, the leaves crumble, along with the pycnidia, spreading the infection. Prevention and treatment of brown and perforated spotting are the same.
A description of the fight against diseases of cherries and a photo of fruits with them would be incomplete without a thunderstorm of cherries and cherries - moniliosis. A sign of the disease is shrunken eyelids, and rotting fruits. The development of the disease is rapid, so even a precocious berry has time to deteriorate.
The task of the breeders was to give the sweet cherry resistance to cherry moniliosis. The fight against the disease consists in the collection and destruction of padanka, plant residues on the ground. For preventive treatment, copper-containing preparations are used.
Whitewashing boles in late autumn saves the tree from gray rot.
On the fruit rot of berries, the growths are arranged in concentric circles, as in the photo, the difference between cherry diseases and their treatment. The leaves remain healthy. The berries are harvested, the branches with the introduced disease are cut off.
Sufficient nutrition mineral fertilizers and spring treatment of wood with fungicides - prevention of fruit rot. On examination, you can determine why the cherry rots on a tree by the location of the pycnidia.
The chaotic arrangement of growths is characteristic of moniliosis. In this case, the whole tree is affected by the disease. Leaves dry out, fruit twigs become brittle, dry, skeletal branches gradually dry out.
If a berry rots in clusters on a tree, this is cherry moniliosis.
Cherry coccomycosis is a disease of a humid warm climate. Red dots appear on the leaves, from below they are covered with pink spores.
The leaves dry up, fall off, the tree does not receive photosynthesis, biological processes slow down. In the winter, cherries leave weakened and freeze.
Prevention of scab - treatment of cherries with iron sulfate in the spring, before flowering. Later, the disease is controlled by the drug Horus.
Why do cherries fall off in the middle of summer? The tree got sick with white rust - a fungal disease. The fallen leaves are removed, and the tree is especially carefully prepared for the winter - all the prerequisites to freeze out.
Cherry wood is weak, not resistant to diseases. Diseases of cherry branches in the photo, and their treatment is pruning and burning diseased wood. Open cuts must be treated with garden pitch.
Even more dangerous is the false and sulfur-yellow tinder fungus, which has chosen cherries. On the tree at the bottom of the trunk, in a crack, white rot appears. The trunk, affected by rot, easily breaks from the wind. The wood softens.
It is impossible to defeat the tinder fungus. It has already grown into the body. It remains to remove the cherry, or regularly remove the build-up. Yields are definitely going down.
The root cause of the introduction of fungi into wood are frost cracks, not cleaned and not closed.
The photo shows a mosaic disease of cherries, and their treatment is impossible.
Signs of the disease are found on the leaf blade in the form of stripes with a changed color, ring circles. The plate is deformed, changes color, dies.
Photosynthesis is disturbed, the tree weakens. But the disease moves deeper, destroys the channels of sap flow.
Prevention of viral diseases lies in the rescue from pest vectors and the purchase of healthy planting material. If a tree is sick with a mosaic, it is impossible to save it, you need to uproot and quarantine the land.
Leaks on the trunk of amber resin should not please the gardener. This is not an infection, but the tree tends to overgrow a non-healing wound, sends new portions of gum into the open wound.
But the trophic ulcer does not heal, the wood rots, and the gum flows. The cause may be an open frost hole, broken branches, or improper pruning.
The gum may leak if the tree is sitting on acidic soil or rising groundwater.
After pruning, the open wound should be allowed to dry, only then cover the dry cut with garden pitch.
To stop the release of resin, the place must be cleaned, treated with copper sulphate, and treated with sorrel leaves three times with 10 minute breaks. After the cut, close the garden var.

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 cherries.
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.
Especially since it's not like that. complex science as it may seem.
cherry is tall tree the pink family. Under 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.
Cherries, like other fruit trees, are susceptible to pest attacks.
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.
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. The gardener can increase the resistance of sweet cherries to harmful bacteria with the help of a good nitrogen fertilizer and moderate watering.
Attention! Excessive moisture and abundant watering of cherries when infected with bacteriosis will lead to the death of the tree.
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 of copper sulphate 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:
Clusterosporiasis. Gardeners know this fungus under the name perforated spot. It affects all parts of the tree.
Because of it, pale brown spots appear on the sweet cherry, bordered by 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 all fruit trees in the 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.
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".
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.
Healthy The Cherry Orchard is a guarantee of a rich harvest of beautiful and tasty cherries. Experienced gardeners carry out preventive measures that provide cherry trees with favorable vegetative conditions in order to prevent cherry diseases and maintain the health of the garden. After all, prevention is always better than cure, and this rule works for trees too!
This article will focus on both preventive measures to protect cherries from the most common diseases, and operational methods for treating trees in your garden. You should know that competent measures to combat cherry diseases, carried out in a timely manner, will restore health and yield to your cherry orchard.
Let's list what diseases gardeners face most often, what are the signs of these cherry diseases, how to deal with them, and what is the prevention.
Common cherry diseases and their impact on crop loss

Bacterial cancer (Agrobacterium tumefaciens) | average |
Cherry virus diseases | |
Cherry dwarf virus (PDV) | low |
Necrotic ringspot virus (PNRSV) | average |
This is a common disease of most stone fruit trees, caused by the fungus Clasterosporium carpophilum. The climatic provocation for its outbreak is due to warm or hot weather with high humidity. Spores of the fungus Stigmina fruit (Stigmina carpophila) are spread by airborne droplets, and so are carried by various insects.
Symptoms of infection with clasterosporiosis (fruit stigmina) are already noticeable in early spring. Spotted red spots appear on the leaves, which eventually turn brown. These spots, which quickly reach a diameter of up to 5 millimeters, are surrounded by a blurry raspberry border, which distinguishes this type of fungus from other infections. As a result of the development of this fungal infection and local drying of the leaf, holes appear in the area of \u200b\u200bthese spots, after which the leaf itself dies.
In addition to leaves, cuttings, buds, flowers, fruits and whole young shoots are affected, with red borders increasing in length. Gum disease is observed. Severely affected sprouts quickly die and fall off. The darkened flowers fall off, the buds turn black and secrete gum, but, dying, remain on the branches. According to such clear signs, even a novice gardener can make a correct diagnosis for perforated spotting.
It is believed that the fungus that caused this disease arrived from Scandinavia around the middle of the 19th century and managed to spread widely, thanks to its natural survival ability, which allows it to endure even severe and prolonged frosts on its fallen and unharvested foliage. Weakened trees often suffer from coccomycosis.
Therapeutic and preventive measures against coccomycosis are identical to the treatment of perforated spotting. When choosing cherry seedlings, give preference to varieties of modern breeding that can significantly resist coccomycosis. Such trees will need fewer treatments for fungal infections.
Infection begins with the leaves, later the bark of the tree is covered with chaotically arranged gray growths. At their location, wood decay begins. Covered with a fungus, the branches crack and become covered with gum and die. The formed cherry fruits are deformed and almost all crumble. The moniliosis mycelium hibernates on the branches affected by it, and if you do not resort to preventive measures, it will successfully live up to the heat and continue its pernicious work.
The fungal pathogen lives in diseased parts of the tree. Here he will overwinter well, if preventive maintenance is not done in a timely manner.
Gum is a transparent, sticky liquid that tends to solidify in the form of a resinous mass. It arises from the places of defeat by fungal diseases. The cause of gum disease can be excessive watering of the soil and excessive feeding of cherry trees.
It is necessary to fight with gum disease. Since the liquid contains pathogenic spores, they will spread to healthy plants by rain and wind. The treatment of gum disease of cherries is to prevent such a condition of the tree, no matter how trite it may sound. First of all, proper care is needed, the destruction of pests, the timely detection of diseases and their treatment.
The spores of the fungus Thekopsora padi, which causes cherry rust, are based in the cones of bushes and trees of spruce species (spruce, juniper), from where they disperse with air currents and are carried by rain through fruit trees.
As a result of infection with rust, reddish spots form on the leaves of cherry trees, bordered by a yellow outline similar to rust. On the surface of the sheet, these signs appear more clearly than on its reverse side.
Signs of manifestation of necrotic ring spot of cherry depend on the strain of the virus and the susceptibility of the cherry tree variety. In spring, rings or spots of chlorotic color form on cherry leaves, this is the main sign of damage to the garden. Some strains of the PNRSV virus can cause very serious losses in the cherry crop.
Necrotic ringspot virus can cause stunting of trees in the garden, leading to the death of buds and shoots on cherries. Such viral infections greatly impair the growth of cherry trees, while at the same time reducing resistance to other diseases.
Especially severe damage from the PNRSV virus can be observed from May to June - during the growing season of cherries. Treatment for necrotizing ringspot virus involves cutting and destroying infected shoots, and sometimes uprooting entire trees. Treatment with chemicals against this virus is not used.
This disease of cherries, which is caused by a pathogenic fungus or bacteria, takes a heavy toll on the health and yield of cherries. Prolonged wet weather favors the spread of this infection, and the onset of infection coincides with the flowering period of the tree.
Such cherry disease as scab is manifested by brown-olive velvety spots on the surface of the leaves. Cherry berries also suffer: green ones wrinkle and do not develop, and ripe ones crack, becoming unfit for consumption.
The universal and optimal requirement for the care and prevention of dangerous cherry diseases is the observance of all agrotechnical measures to maintain its normal vegetation.
After a successful fight against cherry diseases, it is impossible to reduce the level of proper agricultural technology for working with this tree in order to preserve its productive capabilities;
The fungal diseases of cherries described in this article can threaten almost all fruit trees in the garden, and not just stone fruits, damage the crop, distract the gardener's strength and time, and cause some damage to the budget. In this regard, all these measures for the prevention and direct control of the emerging disease of the cherry orchard should go in conjunction with full set agricultural technology care fruit trees.

If there is no desire to remove shoots constantly, then plant trees of the third group. Well, if the tree has already been planted, then you can dig it and insert slate around it to a depth of half a meter. Also in the fall, the excess growth is chopped off, the wound is smeared with garden pitch. Because it’s not possible to simply cut branches with a pruner, you won’t get rid of cherry thickets that way.
The tree can dry out due to bark beetles. If you look closely, you can see small holes on the branches. Immediately cut down those branches that are most covered with such holes and have a lot of gum. Next, the solution of the drug "BI-58", typed into a syringe, inject into those holes that remain on the barrel. A young tree can still straighten out, and if it is old, then it is better to cut it down altogether.

Basal shoots must be removed until the moment when buds form.
Cherry is a plant that appeared about five thousand years ago. There are many places where it grows, and there are many species. a large number of. Cherry varieties can be seen in almost every garden. They are unpretentious and can grow even along the road. In our country, this plant is very popular, the fruits are eaten in any form: fresh, dried, boiled, in pies, dumplings, jam, liqueurs, etc. But to be good harvest, cherries must be properly looked after and monitored for their condition.
After flowering, spray the cherry with the Hom chemical preparation (it contains copper oxychloride). Dilute a bucket of water with 80 grams of powder;
The diameter of the spots soon becomes up to 5 mm. In their place, holes appear due to drying (hence the name of the disease). Soon the perforated leaves fall off. In addition to leaves, flowers, cuttings, buds, fruits are affected. Young infected shoots are distinguished by a bright red edging that increases in length. They secrete a liquid (gum). If the sprouts are severely affected, then they soon dry out, then fall off. Sick flowers darken, then crumble. The buds turn black, releasing gum, dry out, but remain on the tree. These signs are clearly conveyed by the picture. To localize sources of infection, it is necessary to collect and destroy fallen Caterpillars feed on young leaves, entangling them with cobwebs. When buds appear, stamens are gnawed out, then ovaries. In late May - early June, caterpillars go into the soil to a depth of 3-5 cm for pupation. In early July, butterflies fly out, which lay eggs near the kidneys.

The source of moniliosis is stored in the infected parts of the tree, in the leaves, trunk and bark. Moniliosis infects the entire cherry tree completely. Initially, as in other diseases, leaves suffer from moniliosis. After that, the entire crown is covered with characteristic spots. Affected areas rot over time. The shoots from which gum disease occurs deform the berries.

How to fight. Disinfect wounds with a solution of copper sulfate 1%, treat with garden pitch. It is necessary to cut and burn the most affected branches. Carry out whitewashing with lime in spring and autumn. Symptoms. The appearance of red-brown dots on the upper side of the leaves, which turn into spots. A white-pink bloom appears on the lower part of the leaf. The leaves fall off, and the fruits become deformed and dry out. Before the cherry blossoms, you need to shake off all the beetles on the litter, preferably in the morning.
Diseases of cherries, unfortunately, make up a rather large list. There are a lot of them, and each is dangerous in its own way. Therefore, it is very important to learn how to recognize and treat them.
When the cherries are harvested, spray with 1% Bordeaux liquid.
Fighting methods:
leaves and fruits. Sick branches must be cut out, wounds with gum disease should be cleaned and covered with garden pitch or oil paint. Trees are sprayed with the same drugs that are recommended for the treatment of moniliosis.
How and with what to notify? Cherry coccomycosis Parts of cherries infected with moniliosis: berries, affected bark, are promptly removed both from the tree itself and from the root circle, where the carriers of the moniliosis pathogen have fallen. Sections in remote areas are treated with a special solution. The trunk of the tree is cleaned from the painful parts of the plant until it is completely removed.
How to fight. Spray with drugs:
In cherry trees, all ailments can be divided into several groups:
scab - pretty dangerous disease cherries caused by a pathogenic fungus or bacteria. Cut off diseased branches. Disinfect the cut site with a thick solution: 1% copper sulphate plus 3% iron sulphate. Then grease with garden putty; Coccomycosis is a fungal disease. Leaves are more often affected, sometimes fruits of cherries and sweet cherries. First, reddish-brown dots appear on the surface of the leaves. Then they merge and grow into spots.
Loosening trunk circles in early June, when the caterpillars go into the soil.
If the berries begin to crack, then you are watering the trees too much.

Gum disease causes a fungus that occurs on a cherry tree, characterized by the release of a liquid that hardens. Gum treatment is caused by increased dampness and excessive feeding. To avoid cherry disease, take all necessary preventive measures and do not overdo it with care. Cherry does not like excessive watering and a lot of fertilizer, it is better to do this very rarely, but with high quality.

Insects cause no less harm than diseases. Often they are the cause of the cherry disease, so we must not forget to treat the trees from pests.
Lighting should be good, so do not plant trees in shady areas. Clasterosporiasis (perforated spotting). Can completely spread to the whole tree. It starts with the fact that light brown spots appear on the leaves, and then holes form, and the leaves eventually dry and fall off. If such a fungus has fallen on the fruits, then they become depressed, juice begins to flow out of them. When flowers or buds are affected, they simply fall off. How is this cherry disease treated? If you began to notice such signs, then cut off the affected areas with a rhinestone. Treatment and prevention of this disease are carried out with the help of Bordeaux mixture or copper oxychloride. Spraying is done after flowering. |
Three weeks later, when flowering ends, repeat the previous procedure; The treatment of coccomycosis is the same as that of perforated spotting. Behind recent times breeders have bred varieties that are less susceptible to coccomycosis. They need less processing. |
Cherry anthracnose is a fungal disease. In recent years, cherries have increasingly begun to suffer from it. Fruits are mainly affected. During maturation, dull spots appear on them, then small dark tubercles appear, on which a pink bloom subsequently forms. In dry weather, diseased cherries mummify, giving the impression that they have dried in the sun. In wet years, rainy summer the number of fruits affected by anthracnose can reach 80%. After harvesting, when the sawfly harms, spraying the trees |
Cherry coccomycosis This disease is also a fungus. Its carriers are coniferous plants. Therefore, it is recommended not to plant cherries in close proximity to conifers. The leaves of the plant are covered with spots that look like rust. |
Runaway moth

Leaf treatment consists in removing infected areas of the plant. After that, treat the cherry with a special disinfectant solution.
- butterfly, with reddish-brown front wings covered with white spots and a dark transverse stripe, and narrow light gray hind wings with a long fringe. Caterpillars damage leaves, buds, buds and ovaries.
- fungal disease favorable condition for the development of which is wet weather. Cherry damage (mechanical or from pests) contributes to infection.
Also, a solution based on copper oxide helps well in the treatment of trees.
With a strong infection, a fourth spraying can be done two weeks from the third.
The fungal pathogen lives in diseased parts of the tree. Here he will winter well if preventive maintenance is not done in a timely manner.
To get rid of sources of infection, diseased fruits are collected and destroyed. Moniliosis, monilial burn, or gray rot of stone fruits. Fungal disease.
Adult aphids are black, shiny, up to 2 mm in size. Eggs overwinter on young branches. In the spring, at the beginning of bud break, larvae appear from them, which turn into founding females, giving rise to new generations.
rust disease
Runaway moth
Cherry aphid
Symptoms Leaves wither and look like scorched. The bark is covered with gray growths, like the fruits, which leads to their decay. Berries mummify and fall off. Some may remain hanging until spring. Cracks form on the branches, and they die.
Gommoz. This disease often affects felt cherry, which still freezes a little in winter time. When some gardeners try to fertilize the soil more, water the trees harder, then gommosis appears even more often. The first sign of such a disease of cherries is the release of gum from the fruit and trunk. One percent copper sulphate will help here. If not, then use a garden pitch. And cover the wounds with petralatum.
First of all, proper care of fruit trees minimizes the risk of infection;
Almost all cherries are affected: foliage, trunk, shoots, fruits. Therefore, moniliosis is considered the most formidable disease. Affected areas look like burned. Leaves are infected first. Then the bark of the plant is covered with gray growths. They are located randomly. Where such "burns" appeared, rotting of the site begins. chemicals effective treatment with polyram. It is bred (20 g per 10 liters of water) and the trees are sprayed three times: the first time before flowering, the second - immediately after flowering and the third - 2 weeks after the second treatment.

The causative agents of this disease are fungus and bacteria. High humidity and the flowering period are conditions associated with the development of the disease. external environment. External signs of infection are dark green spots on cherry leaves. Fruits are also susceptible to infection. Ripe fruits crack, and young fruits are inhibited in development.
How to fight. Spray cherries during bud break with the following drugs:
- a brownish-lilac insect, about 2 mm long. The larvae drink the juice from the leaves, which is why they dry out.How to deal. Burn all the affected berries, leaves and branches (after cutting them out, capturing 10 cm of intact tissue). Treat the soil and trees before bud break with iron sulfate 3% (600 g per 20 l) or Bordeaux liquid 3% (600 g per 20 l).
Even before the start of sap flow, the first preventive treatment should be carried out. First, the cherry is cut, all sections are treated with a solution of copper sulfate and covered with garden pitch. All trunks and main branches are whitewashed with lime. Then dilute 700 grams of urea with ten liters of water, treat the cherry and the place around it with this remedy. This solution will protect the tree from pests that overwintered in the trunk. But if you did not have time to perform such a treatment, then take Nitrafen or Akarin, or other analogues, and treat the trees with this solution. To make disease resistance better, you need to spray the trees with Zircon or Ecoberin.
Timely collect, burn fallen, diseased parts of the tree;
Affected shoots crack, releasing gum. After which they die. The berries are deformed, almost all crumble.

Flowers, leaves, shoots wither and dry out, outwardly they become very similar to burnt ones. Ash-gray pads form on the fruits. Sometimes rotten cherries take on a dark bluish color and look varnished (mummified).
Leaves, pedicels appear whole colonies of aphids, sucking the juice of plants. The leaves dry up, the shoots are deformed. In summer, part of the winged individuals fly to the root offspring of cherries, bedstraw weeds. In the fall, they return to the tree again. Treatment consists in treating the soil and wood with a solution of nitrafen, during the flowering period, a special liquid is sprayed onto the plant, and for prevention, this action is repeated after flowering. When all the fruits from the cherry are collected, repeat the procedure. If the plant is badly damaged, repeat the procedure after fourteen days.
Karbofos 10% (150 g per 20 l);
How to fight. Spray trees with the following solutions:
Before flowering, spray with Topsin-M (20 g per 20 l), and after - Bordeaux liquid 1% (200 g per 20 l) or copper oxychloride 0.4% (80 g per 20 l).
In autumn period when the leaves have already fallen, perform a sanitary pruning of the trees. And also treat the slices with vitriol and cover with var. During the first frosts, treat the trees under the crown with a 5% urea solution.
Hawthorn, falling on cherry leaves, literally makes cobwebs from leaves. You can fight this disease with Corsair and Actellik. Spraying cherries at the end of summer with these solutions will destroy young caterpillars.
