The garden is inhabited by many insects that are not averse to feasting on juice, leaves or fruits of trees and shrubs. Others harm plant roots. Let's find out which seven pests are encroaching on your crop and are in no hurry to leave the garden!
Yesterday trees were blooming in the garden, but today the inflorescences are glued together and nibbled? Are there any strange growths on the branches, and hairy caterpillars appeared under the leaves? Your plants have definitely fallen prey to dangerous pests!
If the harvest is coming soon and the garden seems to be in perfect order, you shouldn't relax anyway. During the ripening of the fruit, the plants are no less vulnerable. Therefore, if insects appear in the garden, which we will talk about, immediately proceed to protective measures.
So, we present the most dangerous pests that can harm your plants.
The apple tree is one of the most popular garden trees. And the apple blossom beetle is one of its most dangerous pests, which feeds on buds, flowers and fruits. The insect belongs to the Weevils family. Hibernates under fallen leaves and dead bark. In spring, females lay eggs in buds. Soon the larvae appear, the main food of which is pistils and stamens. Sometimes the flower beetle is also found on the pear. A massive invasion of this beetle can completely destroy the future harvest!
If the buds do not open on the trees, and you find a lot of weevils, it is better to immediately spray with insecticides (Karbofos, Fufanon, Tanrek, etc.). Arrange with your neighbors to do the treatment on a specific day. Then the beetle will not temporarily fly to a neighboring site, so that later it will return to your garden.
With a small number of insects, trapping belts and mechanical cleaning of the branches from beetles and larvae can help. As a preventive measure, dig up the soil in the trunks in the fall, remove weeds and fallen leaves.
Along with the apple blossom beetle, the apple moth also inflicts great damage to trees.

Spring work on the protection of berry plants in May
May. During the period of swelling and budding, aphid larvae emerge from the eggs that hibernate on the shoots of raspberries, gooseberries, currants and sea buckthorn, sucking the juice of the blossoming leaves. Aphid colonies - clusters of small, light green insects - live on the underside of leaves. Damaged leaves curl, young shoots are bent, their growth is suspended. In places where the red-gall aphid feeds, the tissue of the leaf blade grows in the form of dark red or yellow protrusions and swellings (galls) on the upper side of the leaves (mainly in red and white currants). Tear off the leaves with colonies of aphids and destroy. It is good that a large number of aphids are eaten by predatory insects: ladybirds, lacewings and their larvae. One larva destroys up to 200 aphids per day, and up to 5 thousand aphids per season, so that in some years chemical preparations can not be used against aphids, but infusions and decoctions can be prepared.
Gooseberries and currants bloom in May, and strawberries and raspberries at the end of the month. During the period of budding and flowering of berry plants, the most dangerous pests fly out and lay eggs in buds and flowers: leaf, flower and shoot currant gall midges, gooseberry moth, sawflies, raspberry beetle; a raspberry-strawberry weevil emerges from its shelters, spider mites and strawberry mites begin to multiply.
Only during this period can the future harvest of strawberries and raspberries be saved from the raspberry-strawberry weevil and the raspberry beetle. The female weevil, laying an egg in an unopened bud, gnaws at the peduncle. Broken buds turn brown and dry, and inside their beetle larvae eat up all the contents of the flower. Instead of juicy sweet berries, young grayish-black beetles (2-3 mm) appear. After strawberries, weevils also damage raspberries.
Before flowering raspberries, a raspberry beetle (4 mm in size) flies onto it, covered with reddish hairs. From the eggs laid by the female in a flower, worm-like yellowish larvae emerge, which feed inside the berries during their ripening. During this period, in the morning, shake the beetles off the plants on a film or in an open umbrella.
In hot and dry weather, strawberry leaves are severely damaged by beetles and larvae of the strawberry leaf beetle and sawflies (belted, combed and others).
The strawberry leaf beetle is a brownish yellow beetle 3-4 mm long. The larva is grayish, six-legged, up to 6 mm. Beetles hibernate under dry leaves and clods of earth. They appear on strawberries during the period of bud exposure, simultaneously with the raspberry-strawberry weevil (when the soil surface temperature reaches 13 °) and gnaw through holes in the leaves or skeletonize them from the lower side. Beetles of the spring generation intensively feed before strawberry flowering, and young beetles - from mid-July to September. In spring, each pair of beetles can destroy 500-900 mm2 of the leaf surface, that is, a part of the leaf blade. Females lay eggs one at a time or in clusters of 3-5 on the underside of leaves, petioles or flowers. One female lays 100 to 200 eggs. The eggs are firmly glued by its secretions, spherical in shape, at first bright yellow, then yellowish-pink.
In early spring, the weather is rather unstable. It can be high during the daytime and drop sharply at night. Under these conditions, the bark on the trees is heated unevenly. Suppose, on a warm March day, the temperature of the trunk in the sun will be 12 degrees higher than on the shaded side. Lime whitewashing of the trunk helps to get rid of such a difference.
In this case, the readings will differ only within 3 or 5 degrees. Overheating of the bark followed by freezing can cause early spring burns. And they will lead to the death of the tree, especially if it is a young seedling. It is necessary to restore the whitewash if it was disturbed during the winter period.
When pruning garden trees in early spring, you need to get rid of damaged branches. They should not be left under the tree, because they are probably infected with: cytosporosis, scale insects, bark beetle larvae, black cancer or other pests and diseases.
Simultaneously with this work, it is required to process the existing wounds on the trunks and branches. Damage is cleaned, leveled with a knife until living tissue appears, then disinfected with a 1% solution of copper sulfate, in a proportion of 10 g per 1 liter of water, and thoroughly cover this area with garden varnish. How to spray trees in early spring
Modern industry offers gardeners many different products for spraying trees at the very beginning of spring. For these purposes, the following applies:
The cheapest drug is copper sulfate. But do not look at its low cost, it is quite effective, so most gardeners prefer it. It is used for scab, fruit rot, curly leaves, black cancer, brown leaf spot and other diseases.
Mineral oil emulsions are liquid mixtures of mineral oil with water and an emulsifier. The emulsifier usually contains:
Emulsions fight against such pests as: aphids, scale insects, help to destroy the eggs of the moth, honey moths and other insects. They should be applied in early spring, before the buds open. In summer, at temperatures over 35 ℃, the emulsion can cause severe burns on wood.
Bordeaux liquid is an opaque, sky-blue solution. Gardeners have been using this liquid for more than a hundred years in the fight against garden pests. It is recommended to use it before bud break. The mixture destroys scab and fungal diseases of trees or shrubs. It is also used as a disinfectant for fruit tree wounds. It is not recommended to store it, it should be used immediately after preparation.
