Photo describing cherry pests and methods of dealing with them
Cherry trees attract not only people who regret eating ripe fruits, but also insects. What are cherry pests and control? Photos and descriptions will help you better study the enemies of plants and find ways to destroy them.
Fruit trees in our gardens are becoming the subject of close attention of insects that infect almost all parts of the plantings. Leaves and ovaries, flower buds and already ripe fruits, small and large branches suffer from pests. With a massive infestation of aphids, caterpillars of various types, leaf rollers mites can cause serious damage to the garden, weaken or even destroy it.
Which uninvited guests are the most dangerous? How to treat cherries from pests, and when is it better to carry out such work?
Cherry weevil
In early spring, when the snow has melted, but the buds have not yet awakened, cherry weevils can be manually shaken off on improvised materials spread under the trees, collected and burned. This method is convenient if low-growing varieties grow in hell, but it is completely unsuitable when a pest threatens large trees 5-7 meters high.
Therefore, a more competent and long-term way is the device of trapping belts. They will save planting not only with veins, but also throughout most of the summer.
When weevils attack, chemical protection means are also used, as well as folk methods. How to spray cherries from pests in this case? Modern insecticides help from beetles, with which they irrigate crowns, boles and tree trunks. Processing is carried out with an early vein, after flowering and in autumn, leaf fall field.
In addition, cherries can be treated with daily infusion of fragrant or pharmacy chamomile. A bucket of hot water will require 100 grams of plant materials and half a bar of crushed laundry soap.
Slimy and other types of sawflies
If larvae appear on the leaves, at the same time resembling slugs and caterpillars, then a slimy sawfly threatens the cherry on the site. The cherry pest shown in the photo and the fight against it should be under the special control of the gardener.
Smooth greenish-black larvae do not exceed 4–6 mm in length and appear on young foliage. Finding himself on the upper part of the leaf plate, the sawfly eats out its juicy part, without touching the veins and the lower part. As a result of such exposure, the damaged tissue dries quickly, and the leaves on the tree become covered with spots resembling burns. Mass infection leads to premature leaf fall, weakening of plants and their poor wintering. In the fall, the larvae enter the soil, and in the spring they fly out, becoming adults, ready for the continuation of the genus by insects.
Close relatives of the described pest are no less dangerous for cherries: yellow plum and pale-legged, cherry sawflies.They also damage leaves and ovaries, and closer to autumn they move to the ground and winter safely at a shallow depth.
To combat the sawfly, insecticides are used if this does not harm the ripening crop. With minimal infection, the larvae are picked by hand or washed off with a stream of water onto a film or cloth spread under a tree.
Instead of chemicals for treating cherries from pests, experienced gardeners recommend taking a strong infusion of smoking tobacco.
Cherry aphid
Cherry or black aphids appear on the tops of young branches in the first month of summer. Rapidly multiplying cherry pests in a matter of days cover the juicy parts of the shoots in a dense ball. Feeding on plant juices, aphids lead to deformation of the affected leaves and stems. As a result, the garden suffers, the yield falls:
- The growth of trees stops or stops.
- Plants weaken, and fungal infections easily develop in areas damaged by aphids.
- The chances of harvesting next year are decreasing.
When the cherry pest depicted in the photo appears, the fight against it should consist not only in the treatment with chemicals, but also in the observance of agricultural technology.
Important:
- to reduce the population of garden ants that carry aphids to cultivated plants;
- carry out competent regular pruning of sick and fattening shoots;
- not get carried away with over-adding nitrogen fertilizers, provoking the formation of young foliage;
- clean the bole from old bark and whitewash the trunks.
In addition to treating cherries from pests using insecticides, they are effective in the fight against aphids. trapping belts, as well as treatment of plantings with an ash-and-soap solution and infusion of mustard powder.
Cherry fly
Seemingly harmless flies can bring no less harm. Cherry fly, for example, is a dangerous pest of cherries, due to which almost the entire crop can be lost. The larvae laid by insects feed on fruits and spoil them. When the cherry falls to the ground, the grown insect for the winter goes into the surface layer of the soil.
Miner flies are no less dangerous. They detect cherry pests along the paths in the leaves. The winding tunnels inside the leaf plates say that the eggs laid have turned into larvae, ready to emerge and become a new generation of adult insects by the spring. In case of mass infection, the leaves suffer so much that the tree cannot properly prepare for winter, as a result of which it freezes, gets sick, and gives a lower yield.
Hawthorn butterfly, goldtail and other cherry pests
Since early spring, not only bees, but also various types of butterflies are circling over the cherry orchard. Not all of them hunt for nectar. The cabbage-like hawthorn, goldtail, cherry moth are vivid representatives of cherry pests.
Caterpillars of these species actively eat buds and foliage, so it is important to recognize the enemy as early as possible and start fighting it. In the caterpillar stage, insects are harvested by hand or sprayed with chemicals. How to treat cherries from pests is up to the gardener himself. But when choosing an insecticide, it is important that the chemical provides long-term protection and does not harm the crop.
Since many butterflies manage to give two or three generations per season, the processing is carried out not only in early spring, but the appearance of foliage, but also at the end of summer.
Cherry pest control and prevention measures
No matter how fast and effective modern means of controlling insects are, treating cherries from pests will not give the desired result if there is no competent prevention.
Fallen leaves are regularly picked and destroyed throughout the season. The same is done with mummified, immature fruits.
Cherry pest control, as in the photo, should consist in irrigating the plants with chemicals. But this is far from the main stage. The main works are carried out in the fall and include:
- pruning sick, dry and damaged branches;
- cuts, as well as cracks in the bark and damaged areas with gum flow, are treated with garden pitch;
- fallen leaves, branches and remaining fruits are carefully picked and burned;
- the soil under the trees is loosened and carefully dug up;
- with the onset of the first cold weather, the garden is sprayed with a 5% urea solution.
In the spring, the condition of the trees is checked again and a comprehensive treatment is carried out against insects and diseases of fruit crops. Most often, for this purpose, systemic tools are used that are effective against a whole range of hazards. It is important to irrigate not only the trees themselves, but also the soil under them. Re-spraying is necessary after flowering. Another treatment can be done in the summer.
