Curliness of peach leaves. Peach diseases - we diagnose and prescribe treatment for fragrant fruits Peach tree disease leaves curl

cultivation peach tree in the garden - the process is laborious. But before you take on the purchase of fungicides ("Delana" or "Strobi") from chlorosis, consider in more detail which diseases and pests of peach and nectarine are the most dangerous and common, and also study the instructions for using the drugs.

Why do leaves curl and then crack and fall off? There are other cases: convex red spots appear on the leaves of a tree, or the tree suddenly begins to turn yellow and shed its leaves. All this, including yellowing and shedding of foliage, does not happen by chance and, as a rule, is only the first sign of the presence of a particular ailment. To know for sure what to do if cracked and twisted yellow leaves, you need to clearly understand the whole variety of peach diseases. Thus, when the threat manifests itself, you will already know it in person.

Clusterosporiasis

How does peach clasterosporiosis manifest itself? Initially, you may notice how small brown spots appear on the leaves of the tree with a border. raspberry color. When the affected part of the plant turns red, bursts and dies, a hole forms in its place. That is why peach disease kleasterosporiosis is often called perforated spotting.

This disease can harm not only the peach leaf plate, but also its shoots. Orange spots form on them, and as a result, the entire branch dies. Such a leaf disease occurs in wet weather or due to winds that spread the causative agent of the disease - a fungus. Spraying the tree during the swelling of the kidneys with copper chloride will help you get rid of the disease.

leaf curl

Processing peach from diseases and pests (for example, chlorosis) may also be necessary in the case of leaf curl. Initially, reddish swellings appear on the leaf plate, which are then covered with a white bloom. The causative agent of the disease is a fungus that spreads from tree to tree during a long rainy spring. Such a misfortune poses a serious threat to a garden peach: if it is not treated with a fungicide (for example, Delan) in time, the leaves affected by the disease will fall off, and the plant itself will first lag behind in development, and then simply die. The main control measures include pruning the affected parts of the tree. After removal, they must all be burned.

powdery mildew

To the most dangerous diseases garden peach should be attributed to powdery mildew. This disease is dangerous not only for the leaves of the plant, but also for shoots and even fruits. All of them are covered with a light coating, a bit reminiscent of a cobweb. The colonies of these fungi are carried by the wind, especially during a hot summer, and therefore your plant, even after effective treatment"Delan" can be re-infected.

To fight with powdery mildew recommended by removing affected shoots, twigs, fallen leaves and fruits. Thus, you will not let the disease spread further. High efficiency also shows the processing of the tree with "Topsin" or "Topaz". To heighten the effect, you can also spray the plant in June with insecticides.

Stone fruit moniliosis

Garden peach moniliosis is also considered dangerous. This disease manifests itself during the growing season, but infection occurs already at the flowering stage of the tree. Twisted flowers of the plant turn brown and crumble. But this is only the beginning. Developing, the disease causes the wood to dry out, penetrates into the ovaries and fruits, because of which they die. You can treat the disease with the help of timely pruning and burning of the affected parts of the tree. Remove fallen fruits from under the plant. Control measures include preventive spraying of the tree with Bordeaux liquid.

fruit rot

This peach disease primarily affects the fruit. They gradually become covered with gray spots, and as a result you get a completely rotten fruit. Interestingly, if the fruits are in contact with each other, you definitely cannot avoid further infection. It is possible to prevent the disease only if a preventive treatment of the plant is carried out before it blooms.

Tree pests

Aphid

Due to the appearance of a frequent guest called aphid, it is not the peach leaves that suffer, but the shoots. The insect literally sucks plant juices out of them, which leads to the drying of entire parts of the tree. And the leaves eventually curl and crumble. It is best to deal with the aphid invasion at an early stage, because with the further development of the disease, only potent pesticides can save your peach.

Weevils

Ticks

fruit moth

It is also recommended to spray the tree against fruit moths. It is a gray narrow-winged butterfly that hibernates under the bark in the same way as ticks. In spring, this pest becomes active and begins to eat peach shoots along with its core. Because of this, the development of the fruit tree slows down, as the shoots begin to wither and die, and the reason for this is just the fruit moth.

In order not to purchase Delan and other fungicides to combat it, remove fallen leaves and fruits from under the tree in a timely manner, and also cut off the dying parts of the plant.

codling moth

Such a pest will easily endure the winter under the bark of a tree, under fallen leaves, or on damaged parts of the shoots. It is dangerous not only because it actively eats shoots, peach ovaries and even young bones, but also because it is a carrier of various fungal diseases. Get a quality fungicide to fight the codling moth.

Effective prevention

In order not to study the measures to combat certain diseases of your garden peach (for example, chlorosis), you need to know what preventive procedures will prevent the occurrence of ailments and pests. You can prevent chlorosis and other ailments by following these recommendations:

  • before flowering, cut dried branches;
  • after pruning, the shoots are burned;
  • with the advent of spring, you need to take care of spraying the tree with chemicals;
  • when the fruits are formed and ripen in July, it is very important to make complex fertilizers and water the tree well.

In order not to treat shoots from chlorosis or powdery mildew on garden peach, preventive measures are necessary.

Video "Proper peach care"

From this video you will learn how to care for a peach in the garden to get a rich harvest.

Peach is a tender tree that is afraid of frost, various pests and, of course, diseases. One of the most typical and dangerous is peach leaf curl. What it is, and how to deal with it, we will tell further.

Did you know? Where the peach spread around the world is not known for certain. The researchers determined that the wild species of peach Prunus davidiana Franch, which is found near Beijing, China, is closest to it. But it is believed that the plant penetrated from northwestern India to Persia, from where it then spread throughout Europe. In Italy, the peach first appeared in the middle of the 1st century. Now actively cultivated in warm parts Eurasia and America.

What is peach leaf curl


The disease is considered the most common and is among the leaders in the frequency of damage to the peach tree. It appears on shoots and young leaves. Moreover, if the leaves are already 2 weeks old, they have a minimal chance of picking up the disease. Most often they get sick at the age of 5 - 8 days.

The disease manifests itself in the form of blistering swellings on the leaves. At first they are light green, then amber-red, and then brown. A wax coating appears on them, where the spores of the fungus ripen.

The bubbles become brittle, and the leaves themselves thicken, dry, blacken and crumble. First, the lower ones, then in the middle of the shoot. As a result, a few leaves remain on its tip, and it looks like a brush. As a rule, one- and two-year-old shoots are affected.

The branches themselves are also affected by the disease. They become yellowish, thicken, bend, and eventually completely dry out. The internodes become thicker and shorter. Accordingly, on next year a tree that has no shoots from the previous year does not bear fruit.

With a strong defeat, the buds die already in the first year of infection, without bearing fruit. If they manage to form, they also become deformed.

Did you know? The source of infection is the spores of Taphrina deformans, a marsupial fungus. Infection of the tree occurs once a year, in the spring. Spores penetrate inside the kidneys, as well as in the cracks and wounds of the shoots, from which the gum begins to ooze. Affected leaves become a breeding ground for new spores, which disperse over the bark of the tree, where they overwinter, and begin a new cycle of infection in the spring. Mainly affects Taphrina deformans fruit trees, but most often nectarines and peaches.


If you do not spray the peach from curliness in time, already in May you can have a completely bare tree in the garden. It is weakening and may not survive next winter's frosts.

Preventive measures for frizziness

The first and main preventive measure to combat curly hair is choosing the right place for planting a peach. It must grow to sunny side, dry place and at a considerable distance from other trees.

Important! contributes to the rapid spread of the disease high humidity air, low temperature environment, sudden changes in temperature. That's why spring period is the most dangerous for the peach tree.

Among preventive measures the most popular is peach treatment with copper sulphate (1%), Bordeaux liquid (3%) or fungicide. Of the latter, "Skor", "Khom", "Raek" are recommended.


Preventive treatment carried out 2 times a year. First - autumn after the trees shed their leaves. Second - in the spring before the first leaves appear. Although some experts recommend that after the first spraying, repeat it after 4 to 5 days.

Important! Spraying is done in calm and dry weather. Otherwise, the wind will carry the solution to neighboring plants, bypassing the peach, or the rain will immediately wash it away.

How to deal with the disease? Preparations for combating leaf curl

Treatment of a tree from this disease is very complex and time-consuming, therefore it is recommended to pay enough attention to preventive methods immediately when planting.

And an important place among them is occupied by sanitary and preventive work.They include pruning or complete removal affected shoots, which must be immediately collected and burned outside the site.

If these events are held in the fall, all the leaves that have fallen from the tree must be burned along with them. In the spring, those shoots are cut off, on which signs of the disease are clearly indicated.

Did you know? There is still no consensus among gardeners - when is it more efficient to prune in the spring: in May, when infected shoots are visible, but the spores have not yet spread through the tree, or in early spring, along with the removal of frozen and dried shoots.


In addition to treating peach with a Bordeaux mixture, the use of fungicides is effective in the treatment. Most often, it is recommended to use "Skor" because it is non-toxic, and therefore safe for the environment and the gardeners themselves.

For one hundred square meters of land, 2 ml of the drug (1 ampoule) is needed, which must be dissolved in 10 liters of water. The therapeutic effect lasts up to 5 days, and the prophylactic effect lasts up to 10 days.

Also apply "Abiga-Peak" at the rate of 40 - 50 g per 10 liters of water. It needs to be used 4 times with breaks of 2 weeks.

Important! Experienced gardeners know that a peach is a finicky plant that requires strict adherence to the rules for caring for it, special climatic conditions. He is equally sensitive to various drugs. If you make even a little mistake with the dosage or spraying period, the tree can shed all the foliage, fruits, slow down their development, or dry out altogether.

Folk remedies for curly hair


As already mentioned, the chemical treatment of peach with fungicides and Bordeaux mixture is the most effective method of controlling the disease. But some gardeners try to use chemicals in the most last turn trying with all his might to cure the plant folk remedies.

Yes, it is recommended to use spraying with tobacco infusion. A kilogram of dried tobacco or tobacco dust is poured into 5 liters of boiling water and infused for 3 days. The infusion is filtered, diluted with water 1: 2 and the affected trees are sprayed 2 times with an interval of 2 weeks.

It is considered effective emulsion,prepared from 90 g of slaked lime and 350 g of softened clay, diluted in 10 liters of water. First you need to dilute the clay with water to a homogeneous state, and then, stirring thoroughly, add slaked lime. The solution must be free of sediment.

It must be used immediately, without leaving the next time. But the expected effect will be obtained only with regular spraying of trees. This rule also applies to other folk methods.

But most often the fungus is resistant to folk decoctions. Therefore, if you do not want to use serious preparations for treating a tree, in addition to trimming peach leaves affected by curliness, it is recommended to spray with 1% Bordeaux liquid, a harmless Biostat product, which includes essential oils, as well as special mixtures.


For example, a mixture of lime and ground sulfur in a ratio of 1:2 or a solution of colloidal sulfur suspension (1%). In this case, spraying is recommended at air temperatures above 25°C. But remember, if folk remedies do not give a visible result, do not neglect the treatment of peach with fungicides.

Leaf curl is a common disease of many agricultural plants and trees. The peach is no exception and, being prone to this disease, can lose a very significant part of the fruit. It is wrong to think that this is only an aesthetically noticeable peach disease - leaf curl causes damage to the shoots, which are deformed, and can lead to the death of the tree, not to mention losses in yield. In this regard, at the first signs of the disease fruit tree treatment measures must be taken.

How is the disease manifested and what is dangerous

It provokes curliness in the period of early spring. This usually happens under conditions high humidity and low temperature. Just at this time, the tree buds, and the spores are activated and start the process of developing diseases that the peach cannot resist. Curly leaves, the fight against which should be carried out already in the early stages, is eliminated precisely by destroying the fungus. If appropriate measures are not taken, the infection affects all leaf buds against the background of marsupial sporulation of the fungus.

The development of the disease begins with the fact that the leaves turn pale, after which they change their shade to a reddish color. From this moment, the peach leaf curl begins. Treatment should begin at the first symptoms, but sparing means. If you start the disease, then the curl will hit the shoots, and eventually the ovaries. Peach fruits harden, lose their taste and become inedible. If the disease is not fought for several years, then in addition to the loss of the crop, you can lose the whole tree, which will die.

Removing affected leaves

Coping with curliness is not easy, but if you approach the fight against the fungus in a complex way, then the result is likely to be positive. Pruning and subsequent burning of affected leaves and shoots is one of the primary means to defeat peach leaf curl. Treatment in this way is usually carried out in May, at a time when the signs of the disease are most pronounced. Also experienced gardeners practice removal in several stages for greater efficiency. For example, the first pruning can be done when flowering is over. The repeated procedure is performed until the spores of the fungal infection disperse.

How to spray for curly

Spraying remains one of the most effective means of combating tree diseases. It is important to consider in what period the peach was infected. Leaf curl, which is controlled after flowering, requires the use of tank biopreparations. These include trichodermin, planriz and pentaphage. Also at this time, fungicides can be used and Before bud break, the same means are used, as well as milk of lime and urea. When the leaf fall has departed, it is necessary to spray the tree and soil in the zone of the stem circle - that is, where the fallen leaves lie. In this case, treatment with the listed means is possible, but without fungicides.

Processing with Bordeaux mixture

Curl protection in recent times Increasingly, 3% Bordeaux mixture is being provided. It should be noted right away that this method has a serious disadvantage: increased phytotoxicity, which, however, well eliminates the curl of peach leaves. The treatment is accompanied by a delay in the entry of the tree into the fruiting period and affects the low yield. In addition, treatment with such a preparation helps to increase the copper content in peach leaves. Moreover, the availability rate heavy metal will increase as the shoots grow.

Despite all the negative factors, there are obvious advantages from using Bordeaux mixture. If in the fight against other diseases its effectiveness may not justify itself against the background of negative factors, then the curl of peach leaves, which is treated regularly with this remedy, will definitely give a beneficial result. This option is especially useful in the fight against an infection that has developed over several years.

Clay processing

If for processing it is rather recommended as a specialized means of combating the disease, then clay is a traditional folk remedy. It is used in composition with lime and acts as an effective adhesive. But not only this property of the substance is important - clay also works as an adsorbent, not to mention the presence of a number of nutrients in the composition. Among them are silicon, aluminum, sulfur and other components that allow you to defeat the curliness of peach leaves. Treatment with folk remedies in the form of clay with lime improves the biological and physico-chemical characteristics of the peach, at the same time nourishing the tree with mineral elements.

If it is not possible to use clay together with lime milk, then the option of using the first one in pure form. In this case, the fungicidal effect will be less pronounced, but the phytocidal properties will manifest themselves quite effectively, eliminating the peach disease. Curly leaves are most easily eliminated with a clay-lime mixture in an optimal consistency, which provides a neutral effect. To do this, the ratio of clay to milk of lime should be 4:1.

Modern remedies for curly hair

It happens that the action of the clay-lime mortar does not help, and the use of the Bordeaux mixture is excluded due to its negative factors in relation to a particular plant. So the question arises of how to treat a peach from leaf curl with minimal harm to the tree itself. The answer lies in the preparations of a new generation, among which are fast, delan and chorus. They can be used singly, in combination, or alternately. In addition, the addition of a clay-lime mortar can significantly prolong the effect of the same delan. According to experts, such drugs provide 98 percent biological effectiveness in the treatment of leaf curl.

Peaches and nectarines are rare guests in Russian gardens. These trees have gained great popularity in the southern regions, because it is there that the most suitable conditions for them reign. However, at present, varieties of peaches and nectarines have appeared, successfully growing and fruiting in the Non-Black Earth Region and middle lane. Regardless of where these stone fruits grow, both nectarine and peach are attacked by pests and diseases. If the tree does not bloom, spots appear on its leaves and fruits, or the skeleton of the plant is completely bare, it makes sense to think that it is seriously ill. With any type of infection, it is important to react in time - to determine the type of disease or pest and start fighting them with suitable methods and means.

Pests of peaches and nectarines

Peaches, along with nectarines, are affected by several types of pests. They love to eat various parts of this culture are leaf-eating, sucking and other types of insects, but record for distribution in peach orchards killed the following pests:

  • peach aphid;
  • scale insects;
  • mining moth;
  • plum codling moth;
  • oriental codling moth.

Each of these pests can cause serious damage to trees, slowing down their growth and development, as well as weakening the tree's immunity. Often, with a high density of infection by them, it is difficult to save trees from frost and disease. This is why it is important to find these insects in the crown in time and carry out regular pest control in the spring and throughout the growing season.

Signs of the presence of pests

It will be very easy to detect pests even for an inexperienced gardener. Firstly, even with their microscopic size, traces of their activity are clearly visible: the leaves curl or become covered with holes, plaque appears on the branches, the ovaries dry or grow severely deformed. In a word, each pest leaves unique traces, which can be found in the table.

Pest names Appearance Signs of its appearance on peaches and nectarines
Eastern codling moth A small (up to 15 mm long) lepidoptera insect (butterfly) with gray-brown wings and a dark body. Young individuals feed on the growth of this year, and adults feed on the seeds of unripe fruits. Pupated insects hibernate in bark cracks and under leaf litter. Young shoots begin to exude gum, crack along, wither and then die off completely. The fruits in which the oriental codling moths feed look healthy, but wormholes can be found on their surface.
peach aphid The insect is of the sucking type. Colonies of pests populate young shoots and suck out all the juices from them. The size of aphids rarely exceeds 1.5 mm. The body of the pest is painted light green At the ends of the shoots, pest colonies are visible. The leaves wrinkle, sometimes curl and dry out. Shoots completely stop growing
Shchitovka A small insect with a body length of not more than 3 mm. It looks like an aphid, but its back is covered with a hard brown or dark gray shell. The larvae of the pest feed on the juices of the plant. Wintering place - bark, or rather its folds The tops of young and last year's shoots gradually wither, become wrinkled or curled. The bark in the habitats of scale insects becomes loose and porous, which is why it is easily destroyed. The plant lags behind in growth, practically does not bear fruit on shoots inhabited by scale insects
mining moth Butterfly no larger than 4 mm. Lays eggs on back side leaves, after which microscopic caterpillars appear from them, gnawing through winding passages inside the leaf plates - mines. They overwinter in cocoons under leaf litter or in cracks in the bark. The leaves are covered with a light pattern of passages gnawed by the larvae of the mining moth, lag behind in growth, turn yellow and fall off early.
plum codling moth Outwardly, it is very similar to the eastern codling moth, but has more large size- up to 2 cm. The danger is represented by its larvae - pink caterpillars up to 1.5 cm long. The pest hibernates in the folds of the bark, entangled in cobwebs The fruits, remaining green, begin to fall off en masse. Upon closer inspection, wormholes can be found on their surface, clogged with a brown substance.

How to deal with pests on peach and nectarine

Pest detection is the first step to saving your garden. It is important to start fighting them in a short time after that. Most effective methods at the same time, agrotechnical measures and tree processing are considered by special means. To the first group protective measures relate:

  • digging the soil in the garden in spring and autumn - helps to get rid of mining moths and aphids wintering in the upper soil layer;
  • removal of leaf litter in the fall - helps to eliminate codling moths and mining moths that have settled down for the winter;
  • cleaning the bark in the fall - helps to eliminate pupated codling moths, scale insects and other pests that have chosen a trunk for wintering;
  • pruning shoots and branches in spring and summer - helps to reduce the number of all pests with too much damage to plants;
  • spraying the trunk and skeletal branches in autumn with milk of lime, which, by the way, helps save the trunk from frost;
  • installation of trapping belts on the trunk for the destruction of codling moth caterpillars in the summer.

For pest control chemicals there are many options, however, for each type of insect, it is recommended to use insecticides appropriate for their family affiliation:

  • DNOC 40% - from peach aphid, scale insects and ticks;
  • Bi-58 (48%) - from scale insects, aphids and mites after flowering;
  • Decis (2.5%) - from codling moths during the growing season;
  • Mitak (20%) - from aphids and scale insects during the growing season;
  • Zolon (35%) - from codling moths, double treatment with an interval of 1 week after flowering.

Also, to protect the garden from pests, you can settle their natural enemies in it, and when trees are infected with codling moths, use pheromone traps.

Diseases of peaches and nectarines

Peaches and nectarines are not among the hardy or disease-resistant crops, however, some diseases can significantly affect the yield and general condition of the trees. They may be affected by the same diseases as others. fruit crops, but The most common infections are:

  • Moniliosis;
  • Powdery mildew;
  • Clasterosporiosis;
  • Curly virus.

These peach diseases have well-defined symptoms. If the gardener regularly cares for peaches and nectarines, it will not be difficult for him to detect signs of tree damage. It is very important immediately after the “diagnosis” to start treating your garden, because many stone fruit infections can easily pass to healthy specimens.

Disease name Signs of infection Fighting methods
Moniliosis Fungal disease that affects the leaves and fruits of peach. On plant organs first appear dark spots, which grow until they cover the entire fruit or shoot. Moniliosis can provoke the death of an entire branch or destroy the entire crown of a tree in a couple of months. First spring processing- during the opening of buds with Horus, the second - after flowering with Topaz, the third - with the formation of seeds in the fruits with Topsin
Clusterosporiasis Fungal infection that affects shoots and leaves. Reddish-brown spots with a crimson border appear on them. Then the spots dry out and fall out. On young shoots, the bark cracks, gum flows from wounds, and galls form on old branches. Treatment of trees with copper oxychloride or Meteor preparation for blooming buds. After flowering, treatment is carried out with Horus or Topsin.
leaf curl Infection that affects the shoots of the first year of growth and leaves. It manifests itself at the beginning of the growing season by a strong deformation of the shoots and leaf plates. The reason why a peach does not bear fruit may be curly, because the ovaries formed on diseased shoots fall off. Treatment of wood after leaf fall with copper chloride or Bordeaux mixture. They are treated with the same means in the spring: at the time of leaf blooming and during the period of inflorescence advancement. You can also treat peaches on a rose bud with Horus or Skor.
powdery mildew A fungal disease that affects all parts of the plant, except for the trunk and large branches (more precisely, their bark). Appears on infected organs white coating, which leads to deformation and drying of leaves and fruits Treatment of trees with Topaz at the time of awakening of the kidneys and the advancement of inflorescences. It is also recommended to prune branches showing signs of powdery mildew in early spring to prevent an outbreak.

It is also important to pay attention to agrotechnical measures: timely pruning damaged shoots and thinning ovaries. You also need to fight insect pests, which are often carriers of infections.

Foreword

To avoid peach disease, constantly inspect the tree, use preventive methods to combat major fungal pathogens and pests. If everything is done on time and correctly, then you can save the peach from death and enjoy a juicy harvest. You should be attentive to all parts of the tree, especially to the trunk.

If brown blotches with a dark red or raspberry border appear on peach leaves, which eventually fall out and form holes, then your tree has been attacked by a fungal disease - clasterosporiasis. In the case of growth, the inclusions merge and form one large spot, which also falls out, leaving behind a vast hole. In addition to the leaves, the fungus affects the buds, flowers and ovaries. The process of their defeat is the same. Infected tissues gradually die, dry up and fall out.

Holes in peach leaves

The fungus feels especially comfortable in wet rainy weather, it winters well on healthy tree organs, forming sporulation. To protect the trees from this peach disease, in the spring, even before the first buds begin to bloom, we carry out. We treat the cuts with a thick solution of lime and a 1% solution blue vitriol. When the first signs of the disease are found, we spray the leaves with 3% Bordeaux liquid before bud break and after flowering. If kleasterosporiosis struck a peach during flowering, then we reduce the concentration of the drug to 1% so as not to burn the leaves and flowers.

After the leaves bloom in the spring, you can notice their deformation. Some leaf plates are not sufficiently formed, others have not yet had time to acquire a saturated green tint, and some even twisted, became wavy, brittle, lost elasticity. If the last leaf variant is present on your peach tree, it is a fungal disease known as curl. Leaf plates affected by the fungus acquire a yellowish-red or light green tint. They soon dry out and fall off. As a result, the tree can completely shed its foliage and be left with bare branches. It ceases to produce fully nutrients and discards the fruits that have not yet had time to form.

Signs of leaf curl

In addition to the lack of harvest, peach trees affected by curly lag behind in development from other horticultural crops, becoming less resistant to winter frosts. good condition for reproduction of the causative agent of this stone disease is rainy damp weather. The fungus is activated during the spring growing season, appearing first as a purple bloom with a border, and after a week forming growths with reverse side sheet plate in the form of a gray plaque. We treat trees for leaf curl as follows. First, we remove and burn the affected leaves and shoots, and then we treat them with copper-containing preparations, such as Skor, Horus, copper oxychloride, Hom, Oksikh.

During the flowering period, brown flowers may appear on the tree, which darken and dry completely. This alarming sign can signal the infection of trees with moniliosis, as a result of which the ovaries are not able to develop, and the already formed fruits are deformed and rot. The fungus is carried by pests of stone fruit crops, such as oriental codling moths, weevils, geese, as well as during pollination by bees from a diseased tree to a healthy one.

Fetus affected by moniliosis

The rapid spread of the fungus is facilitated by wet, cool weather. Per short term both young annuals and formed mature shoots die. As a prevention of infection, the tree is regularly rejuvenated by pruning dry and damaged branches, as well as removing rotten and unset fruits. And to cure peach trees, spray them with fungicides. The first time before flowering with the preparation Horus, the second - after the start of flowering Topaz and third after harvest Topsin-M, not forgetting to also use insecticides if pests have become the cause of the infection.

Why is the tree “crying” - how to prevent gum disease?

On the trunk of almost every stone fruit tree, you can see sticky protrusions that look like cured resin. This is a gum that was formed as a result of the destruction of cells, their membranes and sugary secretions. This phenomenon is called gum disease. It can be caused by various external factors, ranging from improper agricultural practices to adverse environmental conditions.

Peach gum disease

Among the most common causes, there is an excess of moisture, a sharp temperature drop, a glut of nitrogenous fertilizers, mechanical damage to the bark of a tree, infections against the background of other fungal and bacterial diseases (clasterosporiosis, moniliosis, bacterial cancer). As a result, cracks and burns appear on the peach trunk in the form of open wounds filled with gum. It is impossible to leave such a tree without care. Gum treatment reduces peach immunity, quality indicators of the crop, and in advanced cases can lead to death. a large number branches and complete death of the tree.

Wound treatment is carried out as follows. Sharply remove the gum and clean the affected area, capturing 1-2 cm of living tissue. Disinfection is done with a solution of copper or iron sulphate at the rate of 3 g of the substance per 10 liters of water. Next, let the wounds dry slightly and cover them with a thin layer of garden pitch on top. To consolidate the therapeutic effect, before applying the garden pitch, wipe the cleaned places from the gum with fresh sorrel leaves, performing the procedure 2-3 times with an interval of 5-10 minutes.

Exists great amount peach pests. A special place among them is occupied by the eastern codling moth. She is a small butterfly that loves to use given plant for food and as a favorable place for wintering. The larvae of this pest especially like to eat young shoots of a tree, and adults - unripe fruits. In the cracks of the damaged bark, they lay cocoons, continuing to eat shoots and ovaries. To cope with the invasion of the eastern codling moth, we recommend installing corrugated cardboard or burlap traps soaked in a 1% solution Chlorophos.

Eastern codling moth inside the fruit

Among insecticides, spraying with 10% Karbofos, Benzophosphate, Trichlormetafos, 25% Rovikurt has a detrimental effect on pests and their larvae.

fruity or food moth- Another dangerous enemy of the peach harvest. It is a narrow-winged butterfly of a dark gray hue. Like the eastern codling moth, it also hibernates in the cracks of the tree bark, and in the spring it crawls out of its shelter and eats young shoots along with the core. As a result, not having time to form, the branches wither and die. The larvae of these pests eat peach buds and flowers. As a preventive measure, cut and burn damaged and dry shoots, fallen fruits and leaves. As for the main methods of struggle, they are the same as in the case of the eastern codling moth.

Insect Invasion - How to deal with it?

This familiar enemy cultivated plants often affects peach trees. It's about the ashes. Colonies of these small insects damage shoots and leaves, as a result, the leaf plates are folded and deformed, and reddish spots appear at the damage sites. The greatest aphid activity is observed in July. To combat these insects, spray the tree with a solution during the growing season. Karbofos or use the verified folk method, for which dissolve the piece laundry soap in 10 liters of water. For achievement maximum effect when using the second option, leave the peach tree in a soapy solution for 3-4 days. During this period, the aphid colonies and their larvae should completely leave the tree, and the remaining pests can be easily collected by hand.

Significant damage to peach bark is caused by scale insects, which are easily recognizable by their hard shields, thanks to which they protect laid eggs from enemies. A mass accumulation of these pests is observed in May, when the larvae pupate and spread throughout the peach tree. By the end of July, they become adults, and the second breeding season begins. For pest control and as a preventive measure, before bud break, we spray the tree with an emulsion mineral oils, and during the growing season - with a solution of Karbofos.

Particularly dangerous enemies of peach are weevils-flower beetles. Adults of these insects eat buds, flowers and buds, as well as young leaves from the inside. As a result, the tree loses its ability to reproduce and stops growing. In addition, they are the main carriers of fungal diseases.
