Diseases and pests of fruit trees: description and protective measures

A fruit-bearing garden is the special pride of a zealous owner. Every gardener knows how difficult it is to achieve such a result. If sanitary conditions are not observed, green spaces quickly turn into a problem. The main culprits of neglect in the garden are usually pests of fruit trees. A huge number of insects can multiply even more in a short period of time and literally occupy the garden. Let's try to figure out how to deal with bugs, caterpillars and other “aggressors”.

Pests of raspberries, blackberries and strawberries

For your attention - the most common representatives of the fauna, which, like many summer residents, are not averse to profiting from sweet berries (and not only them).

PestHow to recognizeControl measures
Strawberry whiteflyAdult insects “nest” on the underside of leaves. Honeydew (honeydew) is noticeable on the surface of the leaf; later, black spots of sooty fungus spores are visible in its place. Biological

The pest is washed off the leaves with water, then the soil is loosened to a depth of 2-3 cm. Traps are made: a sheet of plywood is painted yellow and smeared with Vaseline. The leaves are treated with a soap solution: 1 part soap shavings to 6 parts water. The parasite encarsia is released into the garden (3 individuals per 1 sq.m.).

Chemical

  • How to protect apple and pear trees from diseases and pests?

    The most effective ways to combat common diseases and pests of apple and pear trees.

Control of pests and diseases of fruit trees: spraying and other agricultural practices

To effectively protect fruit trees from pests and diseases in the fall or early spring, the garden must be cleared of old foliage, and trees and shrubs must be cleared of all diseased branches. It is better to dig up the trunk circles in the fall or loosen them well so that the pests end up on the soil surface and die during the winter.

There are other methods for protecting fruit trees from insect pests. In the spring, when they climb up the plant, and in July, when the larvae pupate, hunting belts are put on tree trunks.

During the summer, you need to collect all the carrion and remove the spider nests in which the caterpillars develop. Prematurely colored berries and brushes intertwined with cobwebs are removed from currants.

To reduce the risk of fruit trees becoming infected with fungal diseases, you need to remember: plants that are not damaged by pests and receive proper nutrition are affected much less frequently.

Plants are highly susceptible to damage after unfavorable winters. Frostbites and sunburn are especially dangerous. The latter occur at the end of winter - beginning of spring, when the nights are still cold and the daytime sun heats the tree bark to high positive temperatures.

As a result, ruptures of the cortex occur. This can be avoided. To do this, the following agricultural technique is used: in the fall, trunks and thick branches are whitened with a special water-based paint. It is better not to use whitewash; it will be washed away by the autumn rains, and there will be no benefit.

Spraying fruit trees against pests and diseases with chemicals must be stopped at least 25 days before harvesting.

However, no matter how hard you try, it is impossible to completely abandon chemical treatments. Of course, at the first appearance of pests, you can use herbal infusions, but if there are a lot of pests, the use of appropriate pesticides is inevitable. The greatest effect can be achieved by observing the optimal timing of treatment, when pests are most vulnerable.

You can find photos, descriptions and measures to protect fruit trees from bushes in this material.

Garden pest control calendar for 2021

Protection of garden plants from diseases and pests is organized not only during the summer season, but throughout the year. In February-March, the trunks and skeletal branches of trees are whitened with slaked lime, protecting them from overheating and cracking; in April-May, the crowns are sprayed with tank mixtures at each stage of plant development, and the bushes are watered with hot water.

In June–July, preventive work is carried out to improve the marketable appearance of the fruits; in August–September, to preserve the harvest. In late autumn (October–November), berry fields and trees are pruned, the soil is treated with urea, leaves, pest nests, and mummified fruits are burned. Even in winter there is work to be done: to prevent mice from making moves under the snow, the tree trunks of fruit trees are trampled down.

Complex treatment of garden plots with preparations that are safe for people and plants is quite effective. Of course, there is more work, but an excellent harvest and the preserved health of garden crops and the gardener are an excellent reward for the work.

Causes of pests in the garden

Preventative measures for garden care are sometimes more effective than treating diseases (especially at the initial stage). If you do not follow them, you can pay for the health of garden crops. To maintain parity you should:

  • purchase seedlings of zoned varieties and hybrids only in specialized stores that are resistant to diseases and pests;
  • sort and disinfect planting material;
  • properly care for plants, taking into account their biological properties (weed, water, prune, loosen row spacing and dig up tree trunks);
  • systematically inspect the plants, removing damaged parts, dry branches, dead bark;
  • destroy large insects and their larvae by mechanical means: by hand, using special tree-trunk belts, shaking them onto the litter;
  • whitewash and spray trees, collect carrion, burn fallen leaves;
  • treat the soil with chemicals and biological products.

Pests appear when agrotechnical requirements are not met. Spring treatment of the garden against diseases and pests is especially important.
