There are quite a few pests of berry crops, however, among their great variety, those whose strong development often leads to significant inhibition of the plant and, as a result, to a sharp decrease in its yield, quality of berries, and sometimes to death of part or even the whole plant stand apart. Let's talk about the most dangerous of them and the means of struggle available to everyone.
HYDRAULIC FIRE
First of all, this pest is dangerous because it completely destroys the ovaries of future fruits, most often gooseberries and currants.
Ognevka is a small grayish butterfly with brown spots and stripes on the front wings resembling flashes of fire. A butterfly does not harm, but its caterpillars harm.
Since the butterfly lays eggs right inside the flowers, it is not possible to immediately detect the presence of damage, it produces a cobweb, which the caterpillars form around damaged and subsequently drying berries.
Autumn tillage in the aisles and under bushes, as well as summer spraying with the Aktellik preparation (16-24 g / ml per 10 l of water) will help just before flowering and a few days after its completion.
You should not thicken the plantations, remove weeds and plant debris in the near-mouth zone in time.
FROZEN GLASS
It affects the shoots of currants and gooseberries. Caterpillars hatch from the eggs laid by the butterfly in the cracks of the shoots, which easily penetrate into the very middle of the branches and gnaw passages, descending along them to the base of the bush. Naturally, such an execution does not go in vain — the branches dry out, and the whole plant may die.
For preventive purposes, it is recommended to cut and burn damaged branches throughout the summer, or to treat with Sumition during the growing season of plants, but not less than 20 days before harvest.
If you cut the shoots, then surely cover the slices with garden paint.
SHEET CURRENT GALLICA
Its young larvae, which live in groups in folded leaves and literally scrap out young tissues, are harmful. Naturally, leaves damaged in this way dry up, which also entails inhibition of shoots - they cease to grow normally and become ugly.
For prevention purposes, it is recommended to dig the soil under the bushes during the winter, and treatment with the Aktellik preparation will help to overcome the misfortune at least 15 days before harvesting.

Gooseberry aphid
It is not the small insect of pale green color that harms the plants, but its larvae - sucking juice from buds, leaves and young green shoots. This leads to the death and deformation of plant organs, a decrease in growth activity, and crop losses.
The only sure way is treatment with Intavir, which is often sold packaged in tablets. Processing is carried out in the spring (before the swelling of the kidneys) and with the appearance of aphids.
FINGERPRINTS OF KIDNEY
Settling in the kidneys, it feeds on their contents, which leads to a strong proliferation of the kidneys, as a result of which they die.
Most often, the tick spreads with cuttings, when propagated, by the wind and even insects.
Prevention measures include pruning and burning affected branches; if the infection is severe, it is better to completely eliminate the bush or cut it off at the soil level. Cuttings for propagation should be harvested only from proven, healthy plants. If damage by a kidney mite already takes place, then treatment in the spring gives good results in the period of exposure of the buds, when the mites usually come to the surface of old buds with a 1% suspension of colloidal sulfur, and this treatment is best done twice - the second time after flowering.
Raspberry-EARTHQUAKE DOLGONOSIC
This small grayish-black bug damages, and very severely, the buds of raspberries, strawberries, blackberries and strawberries; naturally, after his meal no berries are formed. But not only buds are harmed by bugs - in the spring, when young leaves are just opening, the weevil is happy to eat them. Both males and females are harmed, the latter lay eggs, most often one at a time in a bud, combining this procedure with gnawing of a peduncle.
Buds fall - the crop is destroyed. About a week later, in the buds, larvae emerge from the eggs, eat up the bud and pupate in its remains. By about mid-June, young beetles emerge from the pupae, which feed on young juicy leaves and leave for the winter. Thus, without measures to combat weevil from your plantation, there may be nothing left.
Before applying chemistry, all the same “Actellik”, take preventative measures - dig the soil under the raspberry, blackberry and strawberry bushes, this will help destroy the wintering beetles, but if it doesn’t help, then process the plants twice - in the spring, during the period of the inflorescence appearance, and immediately after harvest, when young beetles appear.

Until the age of 33 she lived in Novosibirsk, we had a private house with a backyard and a plot in a gardening society (at one time all large enterprises had such). Raspberries occupied most of the plots; they collected fragrant sweet berries in buckets. Of the pests, they knew the weevil and the raspberry beetle, the larva of which lived inside the berries, but they did not cause much damage. Everyone knows these enemies by sight, they are easy to detect, and how to deal with them, everyone decides for himself - with chemistry, folk remedies or manual collection, if the planting area is small.
But about three years ago, I ran into something incomprehensible; raspberry bushes in some places, regardless of the variety, began to turn yellow and, having already gained color and even forming ovaries, dried up. I read books, leafed through magazines, looked for an answer on the Internet. I would also know what to look for ... At first I decided that it was a disease, but my problem did not fit into the framework of the known and described raspberry diseases. With a zero result, raspberries went into winter, but when the next year the number of affected bushes grew even more, I panicked. What to save your favorite berry from ?!
I began to read everything and only in one small book I came across a description of signs of damage to raspberries with a glass, namely: the shoots break easily in the lower part, or rather, at the soil level.
I immediately went to the raspberry-tree, easily broke off a withering bush and, splitting the trunk below, found a white caterpillar almost as thick as a little finger.
Little has been written about this pest in her book, and full information can be found on the Internet.
