Protection of pome crops from diseases and pests

Botrytis, gray rot

One of the most important factors affecting the yield and quality of fruits is the protection of plants from diseases and pests

Pome crops are exposed to the harmful effects of the greatest number of pests and diseases in comparison with other fruit crops. Unfortunately, modern programs created to combat pathogens often do not provide a consistently high result of plant protection.

Weevil beetle

First of all, this is due to a sharp change in the growing conditions of the culture, an increase in stress factors, a deterioration of the immune system of plants, the appearance of more aggressive pathogens, an increase in the resistance (immunity) of the pathogen to pesticides, a change in the typical symptoms of diseases.

The annual use of the same drugs and defense systems contributes to natural selection and an increase in the number of parasites resistant to them.

Cytosporous desiccation

The increased activity of trade and exchange of planting material without a system of control over the phytosanitary state, especially imported from other regions and neighboring countries, contributes to the spread and development of diseases and pests in new territories that are not typical for them.

For example, in 2008-2009 in the Central Black Earth Region, a similar case was observed with a parasite new to the zone - the Schlechtendahl tick.

Gall mite

The key to successful protection of plants from diseases and pests is meteorological monitoring of diseases and observation of the functional state of plants, photosynthetic activity, etc.

Meteorological observations make it possible to more accurately determine the timing of the treatment of plants from pathogens, and the functional state of plants - the degree of pesticide load.

All of the above should be taken into account and, to one degree or another, correct the main widely used method of calendar treatments according to the phenophases of plant development.

For the prevention of phomopsiosis and cytosporosis, treat the soil of the trunk circles with the fungicide Ridomil Gold at a concentration of 0.2%. Remove and burn diseased trees and individual branches.

Apple scab on fruits, initial stage of development

The timing of treatment against insect pests is more accurately determined by their number. Protection against the codling moth should be carried out if more than 6 insects are found in pheromone traps hanging in the garden in pheromone traps.

During one growing season, this pest is able to change several generations, therefore, spraying from it must be carried out 2-3 times, especially in years with an extended summer. Treatments from apple blossom beetle and leafworm should be started when their number increases to 5 insects per tree.

Apple moth

Protection against ticks is carried out in the presence of three individuals on the leaf, from the apple sawfly 3-4 eggs on sepals, from the honeydew and aphids - when 10% of the shoots are populated.

Weather conditions are of great importance for the choice of drugs.

Pyrethroids (synthetic esters of chrysanthemum acid) are effective only at air temperatures up to + 15 ° С, organophosphorus insecticides and acaricides - above + 15 ° С. Fungicides Strobi and Zato provide high efficiency at temperatures below + 5 ° C and precipitation.

Humpback treehopper

Copper preparations at low temperatures and high humidity cause the formation of a "net" on the fruit and the development of brown spot on the leaves.

Preparations containing sulfur at temperatures above + 25 ° C cause leaf burns. When precipitation falls, contact fungicides are washed off and become ineffective.

When carrying out protective measures, it is necessary to provide for the alternation of pesticides of various mechanisms of action; it is necessary to use drugs of a contact and systemic nature.

Fruit damage with a leaf roll

For convenience and high labor productivity, treatment against pests must be carried out with tank mixtures, mixing compatible preparations in one tank.

Since most pesticides are highly toxic and highly toxic substances, safety rules must be followed at all stages of protective measures.

Tying the trunk with a rodent net


Pesticides (lat. pestis - infection and lat. caedo - I kill) - chemicals used for pest control.

Pesticides combine groups of substances:
herbicidesused for weed control,
arboricidesagainst weedy woody vegetation,
insecticidesagainst insect pests,
acaricides - to combat ticks, nematicides - against nematodes,
fungicidesfungus-destroying parasites, antibiotics (antiseptics, bactericides) - against bacteria,
zoocidesdestroying harmful warm-blooded animals,
rodenticides - against rodents, etc.

By the nature of the action, pesticides are divided into contact (destroying a harmful object in direct contact with it) and systemic (penetrating into plant tissues and killing pests parasitizing on them).

Protection of fruit and berry crops from pests and diseases

In home gardens, special attention should be paid to protecting plants from pests and diseases.

The main pests of orchards in the northern and central regions of the USSR are apple sucker, gray and green aphids, apple flower beetle, ringed silkworm, goldtail, hawthorn, apple moth, apple moth and fruit mites. Among the diseases in the gardens are scab of apple and pear, rot of fruits. Berry plants damage aphids, gooseberry moth, raspberry beetle, raspberry-strawberry weevil from diseases, berry crops damage currant anthracnose, gooseberry powdery mildew, white spot, strawberry gray rot, etc.

In the regions of the southern strip of the USSR, the main garden pests include scale insects (Californian, purple, acacia, plum), apple moth, leafworms, golden moth, unpaired and ringed silkworms, apple blossom beetle, brant, honeydew and others from diseases of fruit and berry plants in scab, black crayfish, powdery mildew, spotting, fruit rot are common in these areas.

In the fight against pests and diseases in backyard gardens, the following activities are carried out.

In the fall, after the fall of leaves, the fallen leaves are necessarily collected and burned and the trunks are dug up, and preferably the entire area.

They clean the dead bark from the boles and main branches on burlap and burn it. This measure is used against the codling moth, gray aphid, ticks and other pests.

In October - November, the stems and main branches of fruit trees are coated with a mixture of lime (2 parts) and clay (1 part), diluted with water to a creamy state. This is done to protect the bark of trees from the effects of sudden temperature fluctuations in winter and early spring. They remove the winter nests of hawthorns, golden-tails, dried fruits and leaves, cut out dry and damaged branches, as well as shoots on which eggs are laid by the ringed silkworm, and immediately burn them.

In the spring, before bud break, fruit trees, currant and gooseberry bushes are sprayed with a 6-8% emulsion of carbolineum or mineral oil (600-800 g of oil per 10 liters of water). This technique is used against scale insects, aphid eggs, honeydew, red and brown ticks, leaf rollers and other pests.

During the budding period, the trees are sprayed with a 4% solution of soap (400 g of soap for 10 liters of water) or a 0.2% solution of anabazine sulfate and 0.4% soap against aphids (for 10 liters of water, take 20 g of poison and 40 g soap). Against weevils and various caterpillars, spraying is done with 1% DDT oil emulsion (100 g of poison per 10 liters of water).

During mass reproduction of weevils, fruit trees and raspberries are additionally pollinated with DDT dust at the rate of 100-150 g per tree and 6-10 g per raspberry bush. Trees are pollinated at the beginning of the flight of weevils, and raspberries - after the appearance of buds on it.

At the beginning of the emergence of buds, trees are sprayed with 1% Bordeaux liquid (against scab) mixed with 0.15-0.2% Parisian greenery and 0.3-0.4% lime (for 10 liters of water 15-20 g of poison and 30-40 g of lime). Instead of Parisian greenery, you can spray with a 3% aqueous suspension of DDT dust (for 10 liters of water, 300 g of dust, DDT). Against leaf rollers and other leaf-gnawing caterpillars, repeat the same spraying after flowering and during the period of fruit formation. Subsequent spraying is carried out after 20 days.

In the case of a strong infection of fruit trees and bushes of true currants, mites are sprayed with a 0.05% emulsion of thiophos (5 g of thiophos per 10 liters of water). Fruit trees are sprayed immediately after flowering, and black currants during the budding period.

With the appearance of a carrion, damaged by caterpillars of the moth, trapping belts made of old burlap, gauze or paper are applied to the apple and pear trees to catch these caterpillars. Fishing belts are examined every ten days and caterpillars are selected from them.

Carrion and rotten fruits are regularly harvested throughout the summer. Unsuitable for use fruits are taken out of the garden and buried in the ground. During the summer, dried and diseased branches periodically peel off and burn. Branches damaged by black crayfish are cut out, capturing live wood, and the wound is covered with carbolineum.

With the mass distribution of gooseberry moth and gall midge (on currants and gooseberries), the soil is dusted with hexachlorane, ”it is added under each bush for 50-100 g. This work is carried out in early spring, before the blooming of flowers and leaves.

Against aphids, sawfly larvae and diseases on currants and gooseberries, they are sprayed immediately after flowering with 1 percent Bordeaux mixture with the addition of 0.15-0.2 percent of Parisian greenery, 0.15-0.2 percent of nicotine sulfate or anabazine sulfate and 0.3-0.4 percent soap. For 10 liters of 1% Bordeaux liquid take 15-20 g of Parisian greens, 15-20 g of nicotine sulfate with the addition of 30-40 g of soap. This spraying is repeated after 10-15 days.

Instead of spraying against aphids, dusting with DDT dust can be applied immediately after flowering.

To combat gooseberry powdery mildew in late autumn and early spring, the bushes and the soil around them are sprayed with a 3% solution of ferrous sulfate (300 grams of ferrous sulfate per 10 liters of water). In addition, 3-4 spraying is carried out with a 0.08-0.1 percent solution of calcium arsenate with the addition of 0.4 percent lime (for 10 liters of water, 8-10 g of calcium arsenate with the addition of 40 g of lime). The first spraying is carried out immediately after the formation of leaves, and subsequent spraying after flowering, every 8-10 days.

Strawberries affected by raspberry-strawberry weevils, leaf beetles and beetles are pollinated with DDT dust during the period of bud appearance at the rate of 2-2.5 g per square meter of area. Against gray berry rot and leaf spot, strawberries are sprayed with 1% Bordeaux liquid before flowering. The same spraying is repeated after picking the berries.

To combat pests and diseases of fruit and berry crops, it is necessary to have on the farm (it is possible for several yards) a hand sprayer and a set of the most important chemicals: copper sulphate, lime, Parisian greens, DDT dust, hexachlorane dust, DDT mineral-oil emulsion, carbolineum, chlorten , anabazine or nicotine sulfate. When using chemicals, you must always remember that Parisian greens, thiophos, anabazine sulfate and nicotine sulfate - strong poisons DDT and hexachlorane dust are also harmful to humans and animals. Therefore, in handling them, you need to be very careful and do not process orchards and berry fields less than 3-4 weeks before picking fruits or berries.

The most common drug - 1 percent Bordeaux liquid - is prepared as follows: 1 kilogram of copper sulfate is taken for 100 liters of water and 1 kilogram of quicklime copper sulfate is dissolved in a small amount of water in a wooden or earthenware dish, and then the amount of water is brought to 50 liters of lime quenched separately in another container and diluted with 50 liters of water too. The resulting milk of lime is filtered, then a solution of copper sulfate is poured into it, stirring constantly, and the Bordeaux liquid is ready. Prepare it immediately before use.

A mixture of Bordeaux liquid with Parisian greens, nicotine sulfate or other chemicals is prepared by weighing Paris greens or nicotine sulfate in accordance with the specified concentration (for example, at a concentration of 0.2 percent per 100 liters of Bordeaux liquid, take 200 g of Parisian greens) and dissolve in a small amount of Bordeaux liquid, and then poured into the total amount and mix thoroughly. Before filling the sprayers, all solutions are mixed and shaken again.

Dusting trees and berries in a backyard garden is usually carried out using gauze bags. They are filled with dust and shaken slightly over the plants. When processing tall trees, bags of dust are tied to sticks or light poles.

Covering and protecting young trees

In November, it is necessary to have time to cover and protect young trees from freezing and various rodents. For those whose summer cottages and gardens are close to the forest, young apple trees, pears and other plants can be gnawed by hares. Now there are a lot of hares, they even run through the streets in our village. They love the bark of young plants, for them in winter it is a good treat. Each young tree must be protected from animals, because it will be a pity for their work and the time spent on growing an apple or pear until fruiting, it takes more than one year.

Protecting trees from rodents

At us for 5 years the pear began to bear fruit. This tree is still young, but with wonderful tasty fruits, we will be very sorry if someone chews on it. Therefore, we protect the pear from rodents every year from the moment of planting. 5 more young apple trees have been planted, one of them is columnar, the trees are 3-4 years old. We decided to protect these young trees from rodents by wrapping the trunk of the pear with plastic mesh, and the young apple trees with covering material. You can, of course, wrap each trunk of a young tree from the root and to a height of 1-1.5 m with nylon tights, they can also save trees from rodents. At the bottom, at the root, it is imperative to secure the tights well.

But we like to protect the trunks of young trees with plastic netting most of all. This net is well secured near the trunk with any wire or rope. At the bottom, we pin it tightly to the ground with iron staples. We wrap the trunk of a young tree near the ground with a small strip of covering material, on which we apply birch tar, and put 2-3 branches of elderberry, a sprig of mint and, if any, a little pyrethrum near the trunk itself. The smell of these plants scares off mice.

Birch tar

And if I wrap the entire trunk of a young tree with covering material, then I apply birch tar from below on the covering material, and under the material itself, near the trunk, I also put plants that mice are afraid of. Can be placed next to young trees and junipers. I put stones around the tree, and under them - burnt rubber, rodents don't like it either. Before the shelter from rodents, I process all trees and shrubs with Karbofos.


Near each young tree, I add OMU autumn fertilizer to the soil. The fertilizer is granular, it is perfect for autumn plant feeding.

Autumn fertilizer

Also, we wrap some young shrubs, which are 2-3 years old, with covering material so that they do not freeze, and mulch the roots with peat 20-25 cm from the ground. And adult trees and shrubs are basically only treated against pests and fertilized every fall.


All our trees and shrubs remain intact after winter and delight us with their harvest.



Take care of your garden pets, and they will delight you with their harvests!

Why do apples and pears rot right on the tree?

- Tell me, please, what kind of disease affects the fruits of apples and pears? The fact is that the fruits rot right on the trees and most of all when it comes to maturity. How to deal with the disease?

Lapotentova L. Agro-town Moshchanitsa.

- Judging by the description, this is fruit rot (moniliosis). Quite a common and harmful disease in the conditions of our republic. In the last three years, it has become especially widespread both in the gardens of amateur gardeners and in industrial plantings. Hot and humid summers create optimal conditions for the development of moniliosis.

Rot occurs as a result of damage to the fruit by insects, hail or cracks caused by the development of scab. A small brown speck appears on the apple, which then covers the entire surface of the fruit with the formation of gray pads, the flesh becomes loose and unsuitable for fresh consumption or for processing. If the disease, as in your case, appears closer to autumn, then the fruits may acquire a black glossy color. You can meet this type of manifestation of moniliosis during storage. Unfortunately, already diseased fruits cannot be saved, therefore, prevention plays the main role in the fight against the disease - protection from diseases and pests. We begin the processing of apple and pear when the fruit is the size of a nut, and continue the entire period of active growth of the fruit. During this time, you will be able to make from 2-3 to 5 treatments. The last treatment should be no later than 30 days before harvest. Of the fungicides we use "Skor", "Fundazol" and "Tersen", while protecting against pests, in particular from the moth, we use insecticides "BI 58" and "Aktara". Today there are no varieties that are resistant to fruit rot. But there are varieties that are less susceptible to the disease. For example, winter varieties. It is they who have thicker skin and greater acidity of apple juice. For example, the Belarusian varieties "Imant", "Vesyalina", "Verbnae" will show very good field resistance to this disease with minimal protection on your part. In addition, agrotechnical methods of combating moniliosis are also of great importance. To do this, it is necessary to collect during the entire growing season and destroy damaged fruits. Timely protection, the correct choice of varieties, the use of sanitary methods to reduce the infectious stock of diseases - will allow you to enjoy the taste of apples from your own garden all year round.

Preparing the garden for spring processing

Traditionally treatment of trees in spring from pests begins with the preliminary preparation of fruit crops. This is largely due to the fact that sometimes in winter, individual branches on trees can freeze and die. That is why the plantings must first be carefully examined and the dead, non-viable branches must be carefully removed on them. For these purposes, it is best to use a hacksaw or fine-toothed file.

After pruning, old bark must be removed from tree trunks. This can be done with a metal brush. Please note that you cannot remove bark on the surface of young trees.

Since the soil around the trees also needs spring treatment, we recommend that you thoroughly clean the near-stem circle of plants from foliage and other plant debris. If you ignore this procedure, pests that have settled around the trunks of plants for the winter will begin to attack the plantings with the first heat.

Such simple preparatory care for horticultural crops greatly enhances the effectiveness of protective preparations. After that, you should decide than splashing fruit trees in spring and how often to do it.

For example, large horticultural farms, in order to obtain the maximum amount of fruit and berry products per season, carry out 10-16 spraying of trees. However, for a small orchard, no more than 4 treatments will be enough in accordance with the phases of plant life.

The main thing is to do this in a timely manner, before dangerous diseases and insects begin their harmful activity. And, given that pests wake up and begin at different times, it is very important to take care of the garden systematically.
