Apricots wither in spring, what to do. Common diseases in apricot

Every spring we are pleased with the sweet and alluring scent of the beautiful color of the apricot tree. And how we wait for the bees to arrive for pollination. With the onset of summer, we look forward to this amber fruit delighting us with its honey taste. The apricot tree is easy to grow if you care for it properly from the time of planting. But we are not always able to notice the problem in time, much less recognize the sign and symptom of tree disease.

There are fungal diseases and viral diseases.

Fungal diseases of apricot

The causative agent is a fungus. It leads to browning and death of all important parts of the tree: flowers, shoots, fruits.

Fungal diseases include:

Moniliosis

Clusterosporiasis

Mushroom Valsa

Vertical wilting

Let's look at each one separately.

Moniliosis (two forms of the disease are distinguished: monilial burn and gray rot of fruits)

Signs: the course of the disease resembles the action of fire - first the flowers are affected, which instantly wither, then the fungal spores spread to the leaves and shoots. Thicker branches become covered with cracks. Everything dries out quickly.

The favorable period of the disease is flowering in cool, rainy weather. Method of penetration - fungal spores are dispersed by wind or insects onto flowers. The mycelium from the flower penetrates and infects the shoots. Insect carriers: leaf rollers, moths, codling moths, weevils. And also when a sick fetus comes into contact with a healthy one. If no measures are taken, the disease: firstly will lead to a 70-80% loss of yield; secondly, the infection will persist until next spring.

Control and prevention measures: In the “green bud” phase, spray with 3% Bordeaux mixture. Immediately after flowering: Horus (3g per 10l of water). 10-15 days before harvesting, with an interval of 10 days, spray with the preparation Switch (5 g diluted in 5-10 liters of water). Teldor is a preparation that can be used during the flowering period until the fruits ripen (8 g per 10 liters of water).

Clusterosporiasis (hole spotting)

Signs: most characteristically manifested on the leaves. Brown spots form on the leaves, which lead to part of the leaf falling out, leaving holes. The shoots become covered with round and then cracking spots, from which gum flows. The affected areas become ugly.

Favorable period of the disease: infection occurs in spring and autumn.

Control and prevention measures: pruning and burning of affected shoots and branches before leaf fall. Spray on the buds in the spring, as well as in the fall after the leaves fall, with 4% Bordeaux mixture or 1% copper sulfate solution. If the summer is rainy, then spray every 15 days. You can also use chorus 3g per 10l of water; it is used in the “rose bud” phase and, most importantly, is safe for bees.

Mushroom Valsa

The disease is infectious - it develops when an infection gets into the wounds of a tree.

Signs: outwardly it is a growth, similar to an orange ulcer.

During the dormant period, it is not recommended to prune the tree in order to avoid infection, and it is also better to keep the soil well loosened. In the fight, you can also use Switch (10g per 10l of water, process 15-20 days before harvest with an interval of 7-10 days).

Verticillium wilt (verticillium wilt)

Signs: the leaves turn yellow at the bottom of the tree, but the top remains green. There are no visible signs of disease on the tree bark. The fungus develops in the conducting vessels of wood and accumulates in the petioles and veins of leaves. As plant debris decomposes, it enters the soil and infects new plants through a cut. Young plants are mainly affected.

Control methods and prevention: prevent excessive soil moisture, avoid close planting of nightshades, strawberries, and tobacco. When digging up the soil, do not damage the roots; discard the affected branches. In the spring, when the buds are in full bloom, and in the fall, during the leaf fall period, spray with Bordeaux mixture.

Viral diseases of apricot

Now let's look at the common ones viral diseases. The causative agent is the smallest living organisms. Organisms are very small and have no cellular structure.

These include:

- plum pox

Apricot ring pox

Viral wilt of apricot

Apricot ribbon mosaic

Let's look at each one separately:

"Pox" plum

Apricot is also susceptible to the plum pox virus.

Signs: in the apricot fruit, depressed spots and stripes are brownish in color, the surrounding pulp is dry. The fruits ripen quickly (about half a month ahead of schedule), the taste of the fruits is low.

Apricot ring pox

Signs: before the onset of hot days, in the spring, you can notice symptoms of “pox” on the leaves. The shoots grow slowly, the leaves are small and the shape may be distorted, the branches dry out. When ripe, the fruit may have characteristic swellings in the form of red-brown spots and rings. Such fruits, with signs of ring pox, fall early.

Viral wilt of apricot

Signs: The surest sign is the simultaneous flowering and appearance of young leaves. Throughout the summer period, light green spots are observed on the leaves, the leaf blade is thickened and twisted. The fruit pulp around the seed turns brown and dies. The reason for the death of a tree is sensitivity to an unfavorable environment. The pathogen is transmitted during budding and grafting.

Apricot ribbon mosaic

Signs: appears in the spring on blossoming leaves. On a healthy leaf, yellow stripes appear along the veins, which safely border the healthy leaf tissue. Then, at this place, a “lace pattern” is formed, which leads to death.

Methods to combat viral diseases: for starters, use only healthy planting material. Try to graft the tip of the shoot. Avoid pest damage and fertilize trees. When pruning and grafting, treat hands and tools with special disinfectants, moving from tree to tree. You can warm up the instruments at a temperature of 50 degrees, thereby reducing the likelihood of transmitting viruses during vaccination. To avoid disease, you can treat the tree trunk with lime and copper sulfate. The result: like a beautiful and healthy tree that bears fruit abundantly.

A healthy garden is the desire of any owner, so we should take a more careful approach to the health of our trees, read literature, and visit gardening forums. And we will be happy to help and answer any of your questions.

We wish you a good harvest!

Apricot tree in the photo

In most cases, trunks and skeletal branches break off under the weight of the first wet snow, ice or heavy snow cover. This also often happens during transportation or when planting trees. Therefore, in the fall, it is better to tie young trees with twine or rope and periodically shake off the snow from them. The first time after planting or transplanting, plants should be tied to a support, this will protect against bending and fractures of the trunks.

Any mechanical damage, frost holes and cuts of trunks and branches should be disinfected with a 1% solution of copper sulfate and covered with oil paint using natural drying oil. It is in the places where the wood is cut that it cracks and dies, and the branches and trees gradually dry out. In years with frosty winters, when damage by low temperatures and sun-frost burns in the spring are possible, it is necessary to immediately cover the longitudinal cracks of the bark with a solution of clay or oil paint in the spring. This is necessary so that the exposed wood is covered with callus tissue and does not die.

Fungal diseases of apricot and their control (with photo)

Fungal diseases of apricot are very common and dangerous. Below we consider in detail some apricot diseases and the fight against them using gardening tools available to everyone.

See what apricot diseases and pests look like in the photo, which shows their typical symptoms and signs of presence:

In the photo, brown spot of apricot

The causative agent is a fungus Gnomonia erythrostoma (Fr.) Auers, f. armeniaka , has a conidial stage - Septoria pallens Sacc. Spotting appears on leaves, petioles, and less often on fruits. The spots are initially inconspicuous, vague, yellow, numerous, gradually they turn brown, dry out in the central part, and bright yellow outlines appear along the edges. Necrotic tissue thickens, becomes folded, and often cracks. Affected leaves curl, dry out prematurely and often remain on the branches. The spots on the fruit are brown, dry, cracking, the affected pulp dries to the seed. The affected green ovaries crumble, and the more ripe fruits are underdeveloped and have an ugly shape. Sporulation develops on the affected tissues and by autumn numerous black dots of small fruiting bodies appear. Spotting causes premature drying and falling of leaves, which negatively affects the winter hardiness of trees and their productivity.

Look at the manifestations of this apricot disease in the photo, where you can see characteristic signs of damage to parts of the tree:

Control measures. Spraying trees before buds open and immediately after flowering with Bordeaux mixture or its substitutes (HOM, Abiga-Peak). If the disease spreads strongly, spraying is carried out in the summer and early autumn with the drug Chorus, taking into account the waiting period for this drug. Timely pruning of dried branches, covering the cuts with oil paint, removing affected plant debris.

Diseases of apricot fruits and their treatment (with photos)

The causative agent of macrosporium spot as a disease of apricot fruit is the fungus Macrosporium sp. The disease appears in late summer, when a wide, blurry red-violet stripe forms along the edges of the leaves. The necrotic tissue becomes lighter in some areas and sporulation of the causative fungus develops in them in the form of a brown coating. When ripe, the fruits soften and are affected by brown spots of plaque. Physiologically older leaves are affected before leaf fall. The infection persists in the affected leaves.

Control measures the same as against brown spot, or gnomoniasis.

Diseases of seedlings and new shoots of the apricot tree and their treatment (with photo)

Apricot powdery mildew (photo)
In the photo, powdery mildew affects a plum

Powdery mildew is a disease of new apricot shoots, its causative agent is a fungus Podosphaera tridactyla (Wallr.) de Vag u. The disease also affects plums and sometimes cherries on new shoots of apricots. The disease manifests itself mainly on the leaves, less often on the bark of young shoots, with a delicate white cobwebby coating. On the leaves of apricot tree disease, plaque is located in the form of separate spots on both sides of the leaf.

As the disease progresses on apricot seedlings, the plaque thickens, darkens, and small spherical fruiting bodies of the wintering stage of the fungus are formed in it. Affected leaves become slightly wavy and yellowish-red in color. Young shoots in places where the mycelium develops turn brown, become denser, may be slightly deformed, and fruiting bodies of the wintering stage of the fungus are formed in the bark.

With severe manifestations of apricot disease and lack of treatment, premature leaf fall, poor ripening of shoots, weakening of trees and a decrease in their frost resistance are observed. The infection persists in the affected shoots and in fallen affected plant debris.

Control measures. Pruning affected dried shoots, collecting and burning fallen leaves. If the disease is severe, trees are sprayed with thiovit Jet during the period of bud swelling. Immediately after flowering, you can treat with paradise or speed.

Look at the photo of apricot pests so that you can promptly recognize signs of their presence on the site:

In the photo, the Gallitz is ocellated.

Gall midge Thomasiniana oculiperda Rubs. - a small yellowish-gray mosquito 1.2 mm long, with six thin long legs. The larva is 2-2.5 mm long, initially white, later dark red. The larvae overwinter in the soil at a depth of up to 5 cm; in May they pupate there and soon the mosquitoes fly out. Females lay eggs on the buds at the budding sites. The hatched larvae bite into the buds and bore oblong passages in the wood of the grafted bud. Damaged buds dry out quickly. Gall midge causes great damage to fruit crops and roses, especially in nurseries where planting material is grown.

Control measures. Preventive spraying of trees in the spring, before leaves bloom, with fufanon or its analogues (kemifos, karbofos), timely removal and burning of dried damaged buds from the rootstock.

In the photo, the white-spotted flat leaf roller

White-spotted flat leaf roller, or white-spotted cresia Croesia holmiana L. (syn. Acalla holmiana L., Peronea holmiana L.) , is a pinkish-orange butterfly with a wingspan of 12-15 mm. The fore wings are rusty orange, light at the base and at the rear edge. On the leading edge there is a large triangular spot with a dark border. The fringe of the front wings is ocher-yellow, the hind wings are gray and darker at the edges. The caterpillar is greenish-yellow, 12-15 mm long, with a light brown head and black thoracic legs. The yellowish-brown chest shield has two black spots on the sides. The caterpillars roughly eat the leaves and, having finished feeding, pupate in the leaves folded to the side. The leaf roller damages pome and stone fruit crops, as well as many deciduous trees and shrubs from the Rosaceae family.

Control measures. Preventive spraying of all trees and berry bushes in the spring, during bud break, with fufanon or its analogues (kemifos, karbofos).

All apricot pests become active in the spring, begin their feeding cycle and at the same time cause destructive damage to the entire garden. Next, we present to your attention dangerous apricot pests and the fight against them in the garden using acceptable means.

In the photo Shy Leafroller

Shy leaf roller Ancylis achatana Den. et Schiff. - a butterfly with a wingspan of 16-20 mm. The forewings are silvery-gray with dark and light streaks and spots, the hindwings are brownish-gray; males have a bend with a tuft of hairs. The caterpillars are 15 mm long, brown, with light hairs and warts. The head, pectoral and anal scutes, and pectoral legs are dark or black. The pupa is 8 mm long, dark brown with black transverse stripes on the abdominal segments. One generation develops. Third instar caterpillars overwinter in a cobweb cocoon in the forks of thin branches, usually covered with a dry leaf. From April, the caterpillars begin to feed, gnawing on the blossoming buds, as a result of which juice drips from them, which later damages the buds, ovaries, young leaves and shoots. Unlike other leafrollers, the shy leafroller does not curl its leaves. Caterpillars pupate in June, and butterflies emerge after 11-14 days.

Females lay up to 160 eggs, placing 1-3 of them along the central vein on both sides of the leaf. After 6-10 days, the caterpillars hatch and skeletonize the leaves and skin of the fruit. Caterpillars weave a web nest and hide in it at the slightest danger. Feeding continues until the beginning of August, the caterpillars molt twice, reach 5 mm in length, spin a web-like cocoon and enter diapause until the spring of next year. The leaf roller damages pomaceous, stone fruit and many deciduous crops, especially those from the Rosaceae family.

Control measures. Preventive spraying of trees in the spring, when buds open and immediately after flowering of gardens, with the drug fufanon or its analogues (kemifos, karbofos).

In the photo, Moth the rip-off

Fruit moth Erannis defoliaria Cl. (syn. Hybernia defoliaria Cl.,) - a butterfly with a male wingspan of 40 mm. Females are wingless, ocher-yellow with black dots on the back. The male's wings are light yellow, the front ones have two transverse dark brown lines and a black dot in the middle, the base and apexes are rusty brown with small dark dots.

Brown caterpillars with two dark stripes on the back and one yellow on the sides. Pupae are 10-15 mm long, light brown. The eggs overwinter on branches at the base of the buds. When the buds open, caterpillars hatch, which feed first on the buds, then on the buds, ovaries, and then on the leaves, pulling them together with a cobweb. They seriously harm stone fruit crops, which damage the ovaries. Having finished feeding, the caterpillars go into the soil and pupate at a depth of 5-10 cm in an earthen capsule. In September, butterflies emerge and fly until late autumn. Wingless females climb trees and, after fertilization, lay from 200 to 350 eggs each, one at a time or in groups. Moth - polyphagous
th pest, damages all fruit trees and many deciduous trees and shrubs.

Control measures. Preventive spraying of all trees and shrubs in the spring, when buds open and immediately after fruit blossoms, with fufanon or its analogues (kemifos, karbofos). In the fall, in September, you can use adhesive belts on the trunks to catch butterflies, and if there are a large number of butterflies, you can spray the trunks and trunks with the same preparations that were used in the spring, strictly observing the waiting period for late-ripening varieties of fruit trees.

Watch the pests and diseases of apricot in the video, which gives practical advice on organizing the care of your garden:

Not all varieties of stone fruit crops are resistant to diseases and pests. Situations often occur when an apricot seedling does not open its buds, or the leaves or shoots of the tree dry out. It happens that fungal infections also affect ripe fruits, nullifying all the gardener’s efforts. In some cases, the tree can be saved, in others it dies completely. And the prospects can only be assessed with a correct analysis of the signs of pathology. And for this, the gardener must know the main diseases of apricot (moniliosis, clasterosporiasis, powdery mildew, etc.) and the most effective methods of combating them.

Description of signs of apricot diseases

First you need to figure out exactly what the symptoms of the disease look like. For example, you should pay attention to the following signs:

• apricot bark cracks - this may indicate the presence of cytosporosis;
• resin on the trunk and branches, forming strangely frozen figures - this is gum production, which can be associated with infectious diseases or wounds;
• brown spots on leaves and fruits can be a manifestation of various pathologies. If, after some time, the leaves curl, this may indicate gnomoniosis;
• green leaves fall, and sometimes there may be no other signs. Why apricot leaves wither and what to do in this situation is a complex question, since the reason may be either disease or lack of nutrients. For example, leaves fall in May due to gnomoniosis and clasterosporiasis. Sometimes it’s even worth contacting a laboratory for a more accurate analysis;
• the appearance of holes on apricot leaves can be caused by clasterosporiasis.

• An apricot seedling does not bud for various reasons, including due to injury to the roots during planting. But it’s better to check the plant for various diseases.
• If the apricot has dried out but sprouted, this may indicate that the tree damaged by cytosporosis can still be saved. So, if the shoots come from the root, then by autumn it will be possible to select the strongest shoot and replant it.
• If the apricot does not bloom after winter or dries out, if the leaves turn red and fall off in June, all this may be a sign of disease and a signal that action must be taken immediately.

Apricot diseases

Apricot diseases and treatment are a very important topic for gardeners. The main ailments of this culture are moniliosis, gnomoniasis, cytoporosis and gum disease. But other options cannot be ruled out. For example, it could be scab. It appears as olive-brown spots on the underside of the leaf. These spots gradually increase in size, then the leaves curl and fall off. This has a bad effect on flower buds, and there is a risk that the tree will not survive the winter. But even if it survives the cold, there will be problems with the harvest: the fruit will grow small and cracked. Other pathologies are no less dangerous.

Moniliosis

One of the most common diseases is apricot moniliosis. Another name for it is gray stone rot. Its symptoms appear in the spring. First, the flowers turn brown and dry out, then the leaves and young fruit branches. In the future, infection of the ovaries may occur. And pretty soon they dry out, and then the same thing happens with shoots and even individual branches. This is why apricot leaves fall off in May. But it doesn't end there. The fruits also suffer from the disease: they shrink, the flesh turns brown, and the skin begins to rot.

Moniliosis

The spread of moniliosis is facilitated by various insects, including oriental codling moths and bud weevils. It is also transmitted through contact between a sick and healthy fetus. Therefore, to prevent the disease, it is recommended to thin out the ovaries after shedding in June.

Primary infection usually occurs during the flowering period. Favorable conditions for it are precipitation - frequent rains, fogs, heavy dew. A cool spring with a long flowering period also promotes its spread.

The causative agent of moniliosis is the fungus monila cinezea bonord. It usually overwinters in the tissues of primary shoots and awakens in the spring. Methods to combat it are below.

Clusterosporiasis

Apricot cluster blight is also called hole spot. This is a fungal disease, and a very common one. Similar pathologies occur in all stone fruit plants. This disease is the answer to the question why apricot leaves turn red in June. Although the disease affects all plant organs, including flowers and fruits, it is mainly the leaves that are affected. They develop reddish or purple spots and may also be brown. But there are so many of them that from a distance the leaves may appear simply red. The spots grow quite quickly, and soon holes appear in their place, surrounded by a red border. These are important diagnostic features that help distinguish spotting from other varieties. The incubation period of the disease is 10-15 days.

Clusterosporiasis

Cytosporosis

Apricot cytosporosis is also an infectious pathology. It manifests itself as drying out of the tree, and primarily affects the bark. At first, only a small area becomes dry, then it begins to crack along the border with healthy tissue. The diseased bark resembles “goose bumps” in appearance; many dark small tubercles appear on it. Inside such formations is the causative agent of the disease - a fungus (it can be of two types - Cytospora cineta or Cytospora leucostoma). Apricot leaves and flowers also dry out, which in such cases may not fall off the tree for a long time. In severe cases of the disease, the fungus can penetrate deeper, into the subcortical layers. This is manifested by the leakage of gum, which leads to disruption of the conductivity of wood vessels.

The affected areas of the bark acquire a yellow tint. Gradually, the damage spreads further and further, and eventually the tree may die.

Important! The description of the symptoms is a bit like black canker, another disease of stone fruit trees. But these pathologies have different pathogens, and black cancer is characterized not so much by tubercles as by concentric circles.

Gnomoniosis

Also called brown spot. It is one of the infectious diseases; its causative agent is the marsupial fungus. This pathology is typical for the southern regions. It mainly affects the leaves, much less often the fruits. The first symptoms become noticeable in the summer already at the beginning of June. First, inconspicuous yellow spots appear on the leaves, which gradually increase in size, become brown, and then cover the entire leaf blade. Over time, the spots in the center of the leaf dry out, and along the edges they become bright yellow, and thickening is observed in this place. Then the leaves begin to curl and dry out, and most often the tree drops them.

Gnomoniosis

If the fruits are damaged, they crack and the pulp seems to dry to the seed. Green fruits most often fall off, while ripe ones remain on the tree, but change shape.

Important! The incubation period of the disease is 6-8 days at an air temperature of 16-21°C. In this case, the infection most intensively affects leaves and fruits of middle age, while young ones often remain untouched.

With gnomoniosis, apricot tends to shed its leaves sooner, about 2 months before the natural start of leaf fall. This leads to a decrease in shoot growth, and in severe situations the entire tree may die, especially in a frosty winter.

Gum treatment

Apricot gum disease (its second name is gommosis) is most often not considered as an independent phenomenon, but accompanies other diseases. For example, it occurs with cytoporosis, klyasterosporiosis, bacterial lesions, moniliosis, when the integrity of tissues is disrupted, and the causative agents of the listed infections enter the resulting wounds. This causes the gum to flow. It is essentially a resin that resembles amber. An accumulation of a yellowish sticky substance can be seen right at the site of the lesion, in cracks in the bark.

The development of this pathology is facilitated by factors such as growing on heavy soils with a high level of acidity, as well as high levels of humidity and lack of nutrients.

Gum treatment

How to revive an apricot

In case of moniliosis, it is necessary to destroy damaged shoots and fruits. After this, treatment with Horus or Topaz 100 EC must be carried out.

It is advisable to treat cytosporosis only in the early stages. If the fungal spores have already penetrated deeply, the tree cannot be saved. The diseased bark is removed mechanically, cutting it off with a knife. The resulting wound must be disinfected, for which a 2% solution of copper sulfate and nigrolic putty are used. If a large area is cut off, you need to additionally bandage it. All affected leaves, fruits, and twigs should be removed so that the disease does not spread further.

If an apricot starts to develop gum, what to do? - a question that is relevant for any gardener. Tree resuscitation begins after sap flow has stopped. The wounds are cleaned with a sharp garden knife until healthy areas appear behind them. Then they are disinfected with a 1% solution of copper sulfate and covered with a mixture of sifted ash and nigrol (in a ratio of 3:7).

To combat gnomoniasis, it is necessary to carry out rejuvenating pruning of weakened trees. The wounds should definitely be disinfected after this. Trees are sprayed with Bordeaux mixture (1% solution), zineb (0.4%) or captan (0.5%) until the end of May. During the month, 2 more sprayings are carried out with a break of 2 weeks. How to spray apricot after flowering? You can use the same chemicals as for the first spring treatments. The next one is done after harvesting the fruits.

Clusterosporiasis is treated with a drug such as chorus during the growing season. Before the buds open, it is advisable to spray the tree with Bordeaux mixture.

The main way to combat scab is to treat the apricot during the flowering period with one of the popular fungicides, for example, carpene 65 WP.

How to fight aphids on apricots? A biological method such as attracting ladybugs does not harm nature, but it is not effective enough if the infection has already begun. Therefore, it is recommended to use insecticides based on pyrethrins or vegetable oils (for example, Vitax Organic). Aktofit and fitoverm cannot boast of such a degree of environmental safety, but they are generally not toxic to humans.

Important! It is recommended to disinfect apricots to prevent aphid invasion in early spring or already in autumn.

Insecticides are also used to treat scale insects. Kinmiks and Aliot are considered the most effective.

Preventive measures

Prevention of moniliosis is the already mentioned thinning of the ovaries after shedding in June. It is important to dig up tree trunks in a timely manner and apply mineral and organic fertilizers. Be sure to carry out the so-called eradicating spraying, for which a 1% DNOC solution is taken. This is done approximately 2-3 weeks before the buds open. It is recommended to spray the tree with 2-3% Bordeaux mixture during the pink bud phase, and after flowering carry out another treatment, but with a less concentrated 1% solution.

Healthy apricot harvest

Prevention of cytosporosis comes down to the fact that you need to check for sunburn or frost damage on the bark. Such affected areas must be disinfected. It should also be remembered that cytoporosis, like other stone fruit diseases, primarily affects weakened trees. Therefore, apricots need fertilizing, especially if they grow in poor soils. Typically, potassium fertilizers are used in such cases. For preventive purposes, drugs are also added to the soil that increase the resistance of trees to diseases, for example, novosil. It is recommended to treat trees with antifungal agents, even if there are no signs of damage.

Important! Measures such as collecting all fallen leaves, even if they remain on the branches, and then embedding them in the ground help against gnomoniosis. In addition, soil cultivation in the area of ​​tree trunk circles is necessary, while simultaneously applying mineral fertilizers.

Prevention of gum disease is timely pruning of trees and preventing injury to the bark.

To prevent apricot pests from appearing in the garden, you need to attract insects that feed on aphids. These are, for example, ladybugs, which are attracted to the garden by the smell of herbs like parsley.

Frequently asked questions about apricot diseases

Perhaps the most common questions among gardeners are why the apricot died and how to revive an apricot seedling.

In the first case, of course, nothing can be done, since the gardener needed to pay more attention to the tree earlier. For example, pay attention to the fact that the green leaves of the apricot are falling off. This tree can die from all the diseases described above if they are not treated. In addition, this is a southern plant, and if the gardener gets a zoned variety, then the seedling must be fed and sprayed, and not only for the prevention of diseases. You should also use growth stimulants (for example, epin), which will help you survive even unfavorable conditions.

How to revive an apricot seedling? This can only be done if the disease has not progressed too far. And first of all, you need to get rid of the affected branches and leaves. If a seedling begins to wither before planting, it can be revived with a solution of camphor alcohol. Take 15 drops of the active substance per 0.5 liter of water. The roots of the seedling and its trunk are moistened with this solution. It is best to do this with a soft brush.

Not all apricot varieties are resistant to diseases and pests. But proper care, proper feeding and timely preventive measures can prevent their occurrence.

Any tree can get sick. The causes of the disease are various factors, depending on the type of tree. Today, many types of apricot are quite resistant to various diseases and pests; there are cases when a virus or disease affects apricot.

Many apricot varieties are resistant to various diseases, but sometimes the disease is stronger

Apricot disease, especially apricot moniliosis and gum disease, are severe disease processes. Not all gardeners are familiar with the types of diseases of apricot trees and their treatment in garden conditions.

It is necessary to take into account the nuances during planting so that apricot diseases do not affect your tree and the taste of the fruit is not affected.

Causes of diseases

Most people, when they lose a large percentage of their yield, attribute this to winter frosts. Why does this really happen?

In 75% of cases, apricot yields decrease due to the fact that the apricot tree is sick, and gardeners are not aware of this, since many diseases may not have obvious symptoms in the early stages.

It is better to plant seedlings in early June, choosing an area where there is light.

There are many ailments that apricots can be susceptible to. These can be diseases, viruses, fungi and mold. The main thing is to understand in time what you are dealing with in order to know how to deal with it. Many gardeners are interested in why diseases appear and how to get rid of them? What to do if the tree is affected by a disease such as gum disease or moniliosis.

Monoliosis

This is a disease with very characteristic symptoms: the tree looks burned in a fire. Do not rush to conclude that the reason for this is an increase in air temperature and solar activity. The cause of the phenomenon is a fungal infection that eats the tree and its root system.

The cause of moniliosis is a fungal infection that eats the tree and its root system

The fungus spreads through the tree through the flower pistil, which swells greatly, signaling a disease. This virus is very persistent and is not easy to overcome.

Methods of protection

Monilial disease must be dealt with promptly. The main thing is to notice the disease at the very initial stages and begin to fight the disease.

1. Carefully monitor the temperature changes so that the apricot leaves do not dry out.
2. Each season, do not forget to treat the plants with Horus or Bordeaux mixture.
3. When the first signs of monoliosis appear, immediately treat all the trees in the garden with a milk mixture so that they cannot get diseases from neighboring plants. The fungus multiplies very quickly and is transmitted by wind and rain.

Many gardeners warn that a lack or excess of calcium has a bad effect on the root system. It is especially important to take this into account when growing seedlings. Proper tree care is also important.

What to do if the tree is already infected

If the leaves have already curled and dried out, then the disease has spread throughout the root system.

All infected branches should be pruned and burned to prevent the spread of the fungus.

If this infection occurred before winter, then there is a chance that the fungus will die from low temperatures.

Mushroom Valsa

A common disease called Vals fungus occurs. Many people have associations with ballroom dancing. The fungus reproduces along the tree in a waltz pattern.

The disease immediately makes itself felt: orange patterns appear on the shoots that resemble a mesh, with a large number of small holes. Growths are observed on the tree bark. If the leaves are curled, an infection can also be suspected.

The disease can be recognized by yellow, wilted leaves and branches that no longer bear fruit. The infection appears in the tree through mechanical wounds. In such cases, you need to keep the soil draining, this can be done using a fungicidal spray that helps control pests.

Disease prevention

After pruning fungus-affected branches, it is necessary to treat the cut area with special means.

If the tree is sick, it is necessary to give it a large amount of vitamins and use a red mixture when processing. Fighting them (viruses) is very difficult and requires strength.

Bacterial spot

In all climatic conditions, a disease such as bacterial spot occurs. This disease manifests itself on the leaves. If brown spots appear on them, then you can begin preventive measures.

If treatment is not started promptly, the leaves will begin to dry out and turn yellow. The disease also spreads to the fruits: they become covered with dark brown spots and begin to dry out from the inside. A burn may appear on the branches. The disease manifests itself:

• through brown spots;
• through a rash;
• the leaves begin to dry out and curl.
