Diseases of the currant - any summer resident will sooner or later encounter such diseases, however, with proper and proper care, such a problem can be very successfully dealt with

A disease such as powdery mildew affects young leaves and shoots that are still growing. At the very beginning, this disease is characterized by a white powdery bloom that forms on the underside of the leaves. Over time, such plaque thickens and darkens, which makes it very similar in appearance to felt. Subsequently, all this will lead to the fact that the leaves will curl, the tops of the shoots darken, bend and eventually dry out completely.

Such a disease should be suppressed literally in the bud, therefore, in order to combat the causative agent of this disease, spraying should be carried out in early spring. For such spraying, a 2% nitrafen solution may be suitable, or you can simply pour boiling water over the bushes. Even before the buds open, it is necessary to spray the plant with a solution of copper sulfate. Spraying mullein solutions can also be called an effective tool. Such an event is recommended to be carried out several times: the first - before the buds bloom, the second and several more times - after flowering begins, while the interval should be at least a week. You can prepare the mullein infusion in this way: pour one part of the manure with three parts of water, after which, such a mixture should be infused for three days. After that, it is necessary to dilute this infusion in half, strain and then you can already start spraying. It is recommended to spray the plants in the evenings or, if the weather is cloudy during the day. In addition, before flowering and after it, the plants should be treated with a solution of soda ash, where it is also necessary to add laundry soap.

Terry is also a very common currant disease. At the very beginning, the disease manifests itself only on the vegetative organs. This is manifested as follows: asymmetry of leaves, elongation and reduction in the number of blades. Actually, the shoot itself turns out to be the so-called foliage. The ovary of the flower subsequently swells. Such terry leaves are visually very easy to distinguish: they are painted in bright pink or purple tones. The only method of struggle will be the uprooting and complete destruction of such bushes.

The most dangerous disease will be a kidney mite. Such a disease also spreads with planting material, clothing and tools. Such buds are easily recognizable by their shape, which appears to be round. This mite itself is extremely small in size, it will develop inside the kidneys themselves. This disease manifests itself in the spring, when pale and yellowish buds become noticeable, which will not bloom, but will subsequently dry out.

From old buds, the tick will be transplanted into new ones that have not yet been infected, this process will last at least another two months. This process will begin even during the discovery of such buds and will last until the end of the flowering of the currant itself, both red and black. Even in the period when the buds begin to swell, the females of such a tick will begin to lay their harmful eggs inside these very buds. Within one month, larvae will already appear from such eggs, after which new females will reappear, which can infect the plant further. When the currant buds begin to bare, the maximum number of mites will have already accumulated in the buds. All these mites will continue to move from those buds that dry up to new and young buds. Such an active resettlement continues at such a maximum rhythm until the end of the currant flowering period. In one season, such a dangerous pest can grow in five generations.

As for the methods of struggle, the infected buds should be plucked out in the spring. Before flowering, spraying with any preparation is necessary. If the infection is very large, then the bush should be cut to its base.
