Treatment of CHERRY and CHERRY diseases (what to do + list of fungicides)

Gardens located in the temperate climate zone and southern regions are home to about 400 species of pests of fruit trees and shrubs. They affect the vegetative system of trees and shrubs in different ways: some destroy buds and ovaries, others destroy leaves, and others destroy bark.

Without appropriate treatments, it is difficult for cherries to resist insects and diseases. To successfully resist diseases and pests, a gardener needs to know everything about effective control methods and timing of treatments.

Ways to protect cherry trees will be discussed in this article.

Folk remedies

Treatment of gooseberries in spring against diseases and pests

Many gardeners do not like chemistry, so they try to use environmental methods of control.

If you do not use chemicals at all, you can use one of the biological compositions: Akarin, Fitoferm, Healthy Garden. Bushes must be treated before they begin to bloom. You can also use chamomile infusion (per 10 liters of water/150g of flowers). Leave for a day. Then add grated laundry soap (half a piece). First dilute it in warm water (0.5 liters).

Akarin

But if last year the crop suffered from any disease, it is better to use stronger drugs.

Note! The effectiveness of natural remedies is not too high - only about 40%. Using them after applying fungicides is not effective.

After treatment, whiten the tree trunks and adjacent branches with a mixture of lime and copper sulfate, and cover the tree trunk circles with ash.

Often, owners of garden plots do not know whether it is possible to spray cherries during flowering. During this period, you should not chemically treat the bushes, as bees and other pollinating insects may die. When the trees have finished flowering, a secondary process of preventative work needs to be carried out. And here the question arises, what to spray the cherry after flowering. They use the same products that they used the first time.

Also recently, Gibberellin (phytohormone - growth stimulator) has become widespread. It is considered a top dressing and helps increase the shelf life of fruits. Its variety, Gibberellic acid, is available in the form of ready-made formulations. These are Pollen, Bud, Ovary.

Gibberellin

They also use brilliant green, they use it to shed the soil under the bushes (10 liters of water / 20g) from the cherry sawfly. Tincture of iodine is used to treat the plant against various diseases.

Common diseases of cherries and cherries

Cherry in general is not a demanding or whimsical garden crop. But, like any other garden crop, cherries are also at risk of infection with phytopathogens, leading to various diseases. Among the most common diseases are the following:

• Cherry cluster blight (hole spot)
• Cherry coccomycosis
• Cherry verticillium wilt
• Cherry moniliosis (monilial burn)
• Cherry anthracnose (bitter gleosporium rot)
• Cherry rustCherry phyllostictosis (brown spot)
• Tuberculariosis
• Cherry scab
• Powdery mildew
• Root cancer
• Cherry gommosis (gum disease)
• Cherry stem rot
• The tinder fungus is flat
• Mosses and lichens on cherry

A separate material on the site is devoted to this topic, which describes in detail the causes of diseases, areas of greatest spread of diseases, external signs and symptoms.

Common diseases of cherries and cherries

What pests are there?

Protecting the garden from various types of troubles is one of the main tasks. To prevent problems, fungicidal preparations are used; they increase plant immunity and prevent the development of diseases of various natures. But trees are affected not only by fungi and viruses; there is another enemy - a pest.

In this case, fungicides will not help; periodic treatment with insecticidal preparations is required. The main difficulty lies in the timely detection of traces of the vital activity of insects, because detection at an early stage is the guarantee that the fight against them will end in victory for the summer resident.

cherry fly

This is a small 5mm insect. There is an orange shield on the black body. Transverse dark stripes are applied to the transparent wings. Larvae (6 mm) are white. The body is characterized by a sharpening at the front.

The pupae spend the winter in the soil without leaving the cocoon. In the last days of May or (depending on the weather) in June, flies appear, feeding on the sap of fruit trees in the garden. Their activity can be traced after the petals fly off the cherry tree at the end of flowering. The danger is that the eggs are laid inside the fruit. We see the result in the wormy berry. Then the larvae appear and eat the pulp with appetite.

Damaged berries become untransportable, lose their appetizing appearance and are not used in cooking. The growth of the cherry fly population causes significant damage to the tree.

Spraying is carried out once, immediately after flowering is completed. Use any insecticide. Repeated spraying is justified only if it is really necessary, but is carried out no later than 3 weeks before harvesting the fruits.

Leaf Cutter Bee

The length of the insect, resembling an ordinary bee, reaches 10 mm. The body is densely covered with hairs. In males it is black, in females there are pronounced orange stripes.

Using sharp chews, insects gnaw off the edges of the leaves so that round areas of regular shape are formed. They use them to make cellular partitions for laying eggs. The leafcutter bee raises the next generation in tree bark or in bee burrows.

Attention! The most effective method of pest control is the periodic destruction of weeds from the Asteraceae family in the garden.

Moth

Large butterfly. The wings (span about 50 mm) are light gray, with multiple dark dots and spots of different sizes and diameters. There are wavy stripes. The body is large (up to 50 mm), similar to a cone. Color can vary from dark green to brown. There are protrusions on the insect's head.

The first individuals appear in May-June, from which time mass flight begins. A mature female lays on average several hundred eggs per season, placing them in folds of the bark. After some time, caterpillars appear from them, sucking the juices from the cherries until late autumn. Later they move to the soil, where they overwinter until the next season.

Attention! Moths are pests of cherries, but they do not ignore other fruit trees in the garden or ordinary deciduous plants.

To ensure adequate prevention, spraying of the garden is carried out three times: in early spring, during bud break and immediately after flowering has completed. Use Fufanon or similar drugs. The product helps reduce the number of caterpillars and butterflies on the site.

If there is a threat of population spread in the summer, periodic treatments are carried out with various insecticidal preparations. The most effective:

• "Kinmiks";
• "Inta-Vir";
• "Aktellik".

Slimy stone sawfly

A small insect with a body length of up to 4-5 mm. Its wings are transparent, with a noticeable darkening at the base and a stripe in the center. The belly is brown and yellow on top. Females lay eggs directly on the ovary, placing them in holes that they themselves have gnawed.

The larvae develop in fruits and berries, even damaging the seed. Pests spread to many trees, but the greatest damage is caused to cherries, sweet cherries, cherry plums and plums.

Treatment with insecticides is carried out during the period when the buds open and immediately after flowering. It is necessary to maintain an interval between treatments. It can be up to 3 weeks. Last spraying is carried out no later than 21 days before harvest.

leaf roller

The subcortical leaf roller is a butterfly whose wingspan exceeds 1 cm. It is active at night and at dusk. The front wings of the insect are bright, with a golden-brown tint.

The caterpillars are off-white in color, with a characteristic brown tint. They live under the bark of trees and feed there. They pose a real threat because they diligently gnaw through vertical passages and poison the plant with the products of their vital activity.

As soon as it gets warmer, the trunk is sprayed for specific protection against insects. This is done at the end of May, during the flight of butterflies. It is permissible to use any insecticidal preparations. After treatment, the affected tree bark is peeled off and the trunk is whitened. In case of large-scale lesions, injection administration of the drug "Actellik" is indicated - dropwise, into the openings of the cortex.

Shoot moth

This parasite lives not only on cherries. There is an increased risk of damage to cherries and other stone fruit trees. It is very easy to identify. The activity is visible on the flowers. In their center, a web appears filled with excrement, and in it there is a caterpillar.

The insect is colored green-brown. Holes appear on the ovary on both sides. The elimination scheme does not differ from the generally accepted principles of controlling other pests.

Mite

A small, barely noticeable sucking pest of brown color, has 4 pairs of legs. The eggs are red and round in shape. With massive damage, the leaf blades of the tree appear rusty.

The eggs overwinter at the base of the tree and at the collapse of the branches. Leaf damage is noticeable visually: first it turns yellow and then becomes dirty white. Up to 5 generations of the pest appear per year. Treatment is carried out throughout the growing season, but the crop must be disposed of.

Attention! Often such a lesion can be seen on felt cherry bushes.

Cherry aphid

Small insect up to 3 mm long. Color: black. Individuals feed on the juice of cherry or cherry leaves. The eggs wait out the winter at the base of the buds, and in the spring the larvae appear.

The main symptom of the lesion is curling of the leaves and noticeable deformation of the shoots. Several generations appear during the season, causing maximum damage in June-July, at the peak of fruiting.

Important! For effective control, treatments should be carried out not only in spring, but also in autumn, choosing drugs that can destroy the larvae.

Spraying for the purpose of prevention is carried out at the moment of bud break. The drugs used are “Fufanon”, “Kemifos”, “Karbofos”. If the infestation is serious, aphids can be poisoned after flowering and in the summer.

Very useful information from an expert in this video:

Cherry leaf beetle

This is a beetle whose body length reaches 8 mm. Color: yellow-blue or black. There is barely noticeable lint on the elytra. The pest attacks the ovary and leaf blades of fruit crops.

The peak of activity occurs in May. Significant damage is observed if the beetle population is very high. For effective control, three-time treatment is needed, carried out before the buds open, after flowering and in early spring.

Plum moth

A dark brown butterfly with a wingspan of about 2 cm. The front pair along the edge is decorated with a clearly visible light gray stripe. The hind wings of the insect are slightly darker - they are gray-brown. The caterpillar is about 2 cm long. It overwinters, comfortably located in a cobweb cocoon located in the bark or in the top layer of soil.

Pupation occurs in spring. A massive flight can be expected in early June. It lasts about 1 month. After 20-30 days after flowering, females lay eggs according to the principle: 1 fruit - 1 egg. After 7 days, caterpillars emerge from them, which bite into the fruits and poison them with the products of their vital activity. One mature female produces at least 50 eggs. In the middle zone, only one generation of insects develops during the season, in the south - 2-3.

For productive control, three times spraying is necessary. It is carried out:

• in early spring;
• when buds open;
• after flowering.

The use of any systemic insecticides is acceptable.

PREVENTIVE protection of cherries from diseases

It has been repeatedly said that the main thing is to prevent a plant disease than to neutralize it. Therefore, the main efforts should be aimed at preventive protection. TWO main measures are, firstly, preventive spraying with fungicides, and secondly, agricultural technology (sanitary pruning of damaged areas, treatment of plant wounds, removal of plant debris, etc.). Preventive measures are carried out once or twice a year, usually in spring (before and during the “green cone” phase) and in autumn (after leaf fall).

The list of preventive measures includes:

• regular inspection and pruning;
• removal of damaged and dry branches, damaged bark;
• regular fertilizing and proper application of fertilizers;
• digging tree trunk circles;
• cleaning, destruction or removal from the site of plant debris, fallen leaves, damaged diseased branches, mummified fruits, etc.;
• treatment of wounds and cut sites with garden pitch, copper-containing or iodine-containing preparations;
• mandatory preventive one-time spraying of cherries with copper-containing preparations (Bordeaux mixture, HOM/OxyHom, Abiga-Peak, etc.) - SPRING (before and during the “green cone” stage) and AUTUMN (after dropping leaves).
• selection of varieties of cherry seedlings resistant to fungal infections (for example, Bulatnikovskaya, Assol, Ashinskaya, Dessertnaya Morozovaya, Dobraya (a hybrid of cherry and bird cherry), Turgenevka, Zarya Tatarii, Shokoladnitsa, Morozovka, Nord Star, Early Yagunova, Kharitonovskaya, Gurtievka, Zhivitsa, etc. .)

What to do

Before you begin the primary treatment of cherries in the spring against diseases and pests, you need to clean up the garden:

• collect leaves left over from last year;
• trim damaged and unnecessary branches, shorten the crown a little;
• loosen the soil around the tree;
• Fill the cracks that appear in the bark with garden varnish.

How to spray cherries in the spring against pests and diseases? After all the above measures have been carried out, you need to spray the bushes with a urea solution (per 10 liters of water/700g). The entire tree and the soil around it are sprayed.

Cherry processing in spring

You can process the plant when warm weather sets in, but before the buds wake up.

Important! Spraying with urea cannot be carried out while the juice is flowing! There is a high risk of getting burned by the budding buds!

After a couple of days, you need to treat the crop again with fungicides.

It could be:

• Bordeaux mixture (3%);
• iron sulfate (for 10 liters of water / 300g);
• copper sulfate (per 10 liters of water / 100 g).

Horus is also considered an excellent remedy. This composition has a general strengthening effect; it protects the plant from fungal and putrefactive infections. No less popular is Corsair, Actellik.

From the chemical series, karbofos is best suited (for 10 liters of water/70g). It will protect you from caterpillars and aphids.

Aktelik

To prevent the movement of harmful insects along tree trunks, trapping belts are attached to them. They are made from burlap folded in several layers or thick paper, width - 15-20 centimeters. The edge of the upper side is tightly tied with twine around the stem. The lower part remains free. Crawling insects will penetrate under it. The inside of the belt is lubricated with some sticky compound (vaseline, honey). The pests stuck in it will not be able to get out and will die.

It is necessary to check the traps several times a week and destroy the caught insects.

Application of FUNGCIDES for preventive and therapeutic treatments of cherries against diseases

Preventive and therapeutic use of fungicides in garden plots is the norm. You can't do without them. To treat cherries against phytopathogens, the following are used:

a) COPPER-CONTAINING preparations

Among the most common and practically used copper-containing drugs are the following:

• 1% solution of copper sulfate;
• preparations based on copper oxychloride/oxychloride (for example, ABIGA-PIK, KHOM, OxyKhom, Homoxil, etc.);
• 1-3% solution of BORDEAUX LIQUID (copper sulfate + calcium hydroxide);
• and etc.

b) IODINE-CONTAINING preparations

One of the representatives of iodine-containing drugs is the drug “PHARMAYODE, 10%”. "Farmayod" is an effective disinfectant and antiseptic drug with a wide spectrum of action. Provides long-term protection of cherries from fungal, bacterial and viral diseases. Treatment is carried out by spraying. Dosage 5-10 ml/100 m2. Spraying in phases: green cone, ovary with a diameter of 2 cm, after harvesting. Consumption of working solution is up to 5-10 l./100 m2. Number of treatments – up to 3 times.

c) SALT-CONTAINING preparations

The drug "NITRAFEN" based on sodium salts of acylphenols has excellent bactericidal and disinfectant effects. The drug "Nitrafen" works both as a fungicide (protection against common diseases - scab, moniliosis, clusterosporiasis, cocomycosis, curl, rust, powdery mildew), and as an insectoacaricide, which also makes it possible to effectively destroy wintering garden pests that lay eggs ( leaf rollers, aphids, scale insects, mites, etc.). Early treatments will prevent them from laying eggs and larvae in a timely manner, which in turn ensures a significant reduction in the number of insects.

d) MULTI-COMPONENT and SYSTEMIC FUNGICIDES

Modern drugs are now widely used to treat cherries and other stone fruit crops against a range of diseases. Among the available and often used in practice are:

• the drug "SKOR" is a systemic fungicide with preventive, therapeutic and immunizing effects based on 25% difenoconalosis;
• preparations "KUPROLUX" or "ORDAN" - two-component fungicides (copper chloride + cymoxanil), etc.;
• the drug "STROBI" is a local-systemic fungicide (cresoxim-methyl, 50%), the active substance inhibits the process of mitochondrial respiration in fungal cells, completely blocking their development.

How to spray cherries in spring to improve harvest

Even with the presence of pollinating trees on the site, the yield of fruit crops is not always high. For example, a cold and cloudy spring may affect the volume of fruiting; bees and bumblebees are reluctant to fly in such weather, and pollination is incomplete.

To improve the quality of pollination and harvest, you can use a honey solution. About 150 g of natural honey is diluted in a bucket of water, and then flowering trees are sprayed with this mixture. Bees, attracted by the sweet smell, begin to pollinate the tree more actively, and accordingly, the harvest becomes higher.

To improve productivity, you can artificially attract bees to the garden

Summer

In the summer, the garden is most often sprayed with urea. As mentioned above, this fungicide perfectly saturates trees with nitrogen and also kills many types of pests. The procedure is carried out several times during the hot season; urea is used as a nitrogen-containing fertilizer.

Basically, in the summer, special preparations are used to spray the garden against certain types of pests. More precisely, in order to combat insects that have managed to get into the garden and occupy the trees. You can purchase such insecticides at any specialized store.

They try to treat young plants with folk remedies, since they are absolutely safe for young plants (“strong” fungicides and insecticides can leave burns on the seedlings). For example, against aphids, the garden is sprayed with tobacco or another strong-smelling tincture. These insects cannot tolerate strong odors.
