The mite on the currant: measures of struggle, pest photo

Many summer residents planted on the site of bushes of currants. This berry is extremely useful, it grows well in the middle zone and tolerates frosty winters. But, like any garden shrub, has its enemies and pests. Quite often there is a kidney mite on the currant, the fight against which is cardinal and soft.

How to identify a pest and what harm does the tick inflict?

A small insect of a currant-berry mite all his life spends on a bush of a currant. This is a small (0.15-0.3 mm) creature with an elongated body in females. In the proboscis region, 2 pairs of legs and 1 pair of legs are placed. Female is twice as large as males. If a bud tick on the currant has appeared, the measures to combat it can lead to different consequences. Therefore, it is necessary to act very carefully.

The insect winters in the kidneys, and with the onset of heat is activated. Females lay eggs in young kidneys. Soon from them hatch larvae. As they grow, they become cramped in one kidney, and they spread to neighboring ones. So the whole bush is affected, as well as everything growing next to it. The way the kidney tick is affected by young shoots, the photos show best.

The diseased kidney does not develop, but if it escapes from it, it will mutate. In addition to reducing the number of shoots and less harvest on the currant, the insect is a carrier of viruses. From it, the bush can become infected with curly or marbled. From viruses, currant is not treated, and the bush is to be removed. There are several methods of struggle. Among them is to choose the most convenient and suitable.

Boiling water is the most effective remedy

Most gardeners try to solve the problem with the least loss. Pouring boiling water kills all the larvae - they are welded, and the bush does not cause harm, on the contrary, it becomes stronger. In addition, this process increases the immunity of the plant against powdery mildew.

When watering, you need to follow several rules. Firstly, do not use 100% boiling water. While water is carried to the garden, while it is poured into the watering can, it cools down a little, which does not damage the young buds. Secondly, to make the shower more effective, it is necessary to tie the branches together, to make them more compact.

The disadvantage is that the kidney mite on the currant measures it against him. He begins his activity with the first warm rays, and at the same time the kidneys begin to swell. If the bush is already awake, then it can not be processed. It is necessary to choose a period when it has already warmed up, but there is no green haze on the bush. Also, dirt on the site can make work difficult. Pouring (except for the spring period) can be carried out in winter, when the currant will discard the leaves and become visible to the damaged kidneys.

Manual removal

Patience and attention requires the method of manual selection of the kidneys. In this case, the main thing is not to miss the time. It is suggested to study how the buds tick on the currant, photos, and the measures against it. Kidneys should be rounded, swollen and resemble cabbage heads. If one of them has already opened, then the tick from it, most likely, has already passed to another.

Sorting of the kidneys can be done in winter or early spring. The disadvantage of the method is that in carrying out such a process in spring, the probability of removing young shoots is high. Before opening, all the kidneys swell, so visually distinguishing patients from healthy becomes difficult.

Another drawback is that you need to study the entire bush. If at least one infected kidney is left, the pest reproduction will continue. Measures to combat currant buds will be unsuccessful. The key to successful kidney removal is in a thorough examination of photos of the affected bushes. Only with full confidence that the gardener can remove all the diseased parts of the bush, you can begin to inspect. After getting rid of the infected kidneys, they are collected in one place and burned.

Chemicals from sulfur

Among the chemical preparations for fighting insects are colloidal sulfur and calc-sulfur broth (ISO). A cormorant kidney mite, the control measures against which can have a negative effect on the bush, does not tolerate sulfur, since it is sensitive to this element. It is applied as a solution of 10 grams per liter of water. She is treated with bushes during the beginning of flowering and after its termination. The second time you can make a less strong solution. Although this year the harvest may be spoiled, but next year it will recover.

ISO is used in the same way. The solution for the first spraying is 2%, and for the second one - 1%. When spraying, you need to carefully handle all affected and healthy branches, as well as the ground at the roots of the plant. Some drugs can be used before the kidney swelling period. It is necessary to read the instruction so as not to be mistaken with the proportions.

In addition to fighting mites, sulfur increases the immunity of currants against fungal diseases. In some plant varieties, preparations with its content cause the leaves to fall off. This must be known before spraying.

Cardinal measures - pruning

When the kidney mite on the currant fighting measures ignores and continues to develop, it is necessary to move on to cardinal actions. These include circumcision of the shrub under the root in the autumn period or its complete destruction.

In the first case, shoots of damaged currant are cut in autumn. All of them are collected and burned, so that the parasite does not spread further. Such a procedure will not harm the currant. In the spring new shoots appear and a healthy bush is formed. The only drawback - the crop may not be at all or for several years. Until the bush recovers, it will be much lower than before pruning. Usually rejuvenation of the bush gives only a positive result.

The second method is suitable for severely affected shrubs with signs of viral diseases. If you do not get rid of it in time, you may spread the parasite to other garden crops. The bush is excavated and burned at the place where it grew.

One of the most harmful viruses is the kidney mite on the currant. A few know how to deal with it. After all, he can stay on the tools with which the bush was cut or dug. For prevention, they can be treated with any modern detergent or special chemicals.

Folk remedies

How to deal with the kidney mite without using dangerous measures? You can use folk remedies for this. These include tea and garlic. Garlic is a plant that repels many parasites and carriers of various diseases. It can be planted between the currant bushes as a preventative.

If the infection has occurred, then before and after the flowering, you can spray with strong garlic broth. To do this, take 100-200 grams of peeled garlic, finely chopped and poured with boiling water (10 liters). After mixing the broth, you can start spraying the bushes. If flowering has already begun, then tincture can greatly affect the process of pollination. As an alternative means for spraying, you can use a decoction of dandelion, walnut or tobacco.

Tea preparation is prepared in the proportion of 50 grams per 25 liters of water. She is treated with young cuttings before planting. The branches are immersed for 3 hours. You can soak in a decoction. For a day it will become less harmful and will not burn fragile planting material.

Acaricides - an alternative to sulfur

Many gardeners do not know what else is the kidney tick on the currant, measures of struggle against which can harm the bush. Prevention of acaricides is best perceived. They produce spraying not only from the tick, but also from other insect pests. On the market, drugs of this category are represented in a wide range. Before use, read the instructions for use.

Prevention as the best method of struggle

If a bud tick on a black currant has appeared, the control measures can be different. But it is better not to admit his appearance. To do this, you need to periodically update the bushes, monitor the quality of young plants. Timely fertilizing, fertilizing and proper care will strengthen the immunity of currants to mites and other diseases.

For every gardener, a big test is a kidney mite on the currant. How to deal with it correctly, very few people know, because there are many methods. If there is time, you can test several of them. But the earlier the fight with the tick begins, the less damage it will do to the plant.
