Diseases of the currant

Currant, like other garden plants, is not immune from various diseases. What can prevent you from obtaining the coveted harvest and how to cure this plant in case of disease?

Rust

Let's start with such a disease of currant as rust. She often strikes bushes in cottages. On the bottom of the sheet appear patches of orange. In the case of exacerbation of the disease, the leaves from the currant completely fall off. Bushes become weak, yield decreases.

How to deal with rust? First, you should avoid planting currants in those places where sedge grows, and do not plant bushes too thickly. Carefully clean the area of weeds. In autumn, dig deeply the soil and put autumn leaves into it. To fight the disease, spray plants with a solution of copper or iron sulfate, as well as Bordeaux fluid.

Anthracnose

For such a disease of the currant, as anthracnose, the appearance of small brown spots, which have a darker color at the edges, is characteristic. He affects not only the currant, but also gooseberry in early May. Spots with time grow and merge into one, and the leaves begin to turn yellow, twist and fall off. The red currant disease is affected by fruits, stems and petioles of leaves. Anthracnose leads to premature fall of leaves and delayed shoots in growth.

In order to combat anthracnose, the soil needs to be dug in early spring and late autumn, mixing leaves fallen from the bush there. Before buds are dissolved, plants need to be sprayed with a solution of copper or iron vitriol (50-100 or 300 grams per 10 liters of water). During the growing season, the plant needs to be sprayed four times with a 1% solution of the Bordeaux liquid. When spraying, it should fall on both sides of the sheet - both upper and lower. The first time a currant needs to be sprayed when the buds bloom, the second after flowering, the third - 10-15 days after the second, the fourth - after harvesting.

American powdery mildew

No less harm than anthracnose, the currant inflicts American powdery mildew. How do you know if the currant has been affected? On the leaves appears a white mealy coating, which eventually becomes dense and changes its white color to brown. Fungus, which is the causative agent of this disease, affects only young organs and currant tissues - annual shoots, unripe berries, recently blossoming leaves.

To avoid this disease of the currant, in the fall, the old branches and fallen leaves are cleaned from the site, as well as affected shoots (in all these places, as a rule, the mildew of American powdery mildew tolerates winter). Early in the spring, while the buds are not yet budding, it is recommended to pour the bushes with hot water. Since the beginning of spring, plants are recommended to spray cow dung, which should be diluted 6-8 times with water. For the prevention of this disease, use an infusion of wood ash - 1 kg per 10 liters of water, which is heated in the sun. The solution is insisted for 5-7 days or boiled for half an hour. After that, you need to drain it and add a little soap. The thick must be diluted to 10 liters and after that you can spray it with bushes.

Makhrovost

As for such a disease of currant, as mahrovost, it can completely deprive the plant of the crop. Makhrovost attacks the black currant and is transmitted by the kidney mite. This disease can be detected during flowering. The blades on the leaves become just three instead of the usual five, they are lengthened and sharpened. The leaves lose their habitual smell of currant and appear to be darker in appearance than healthy ones. The calyx, corolla and stamens acquire a violet color, and the flowers wither and stay on the branches for a long time. Berries on diseased branches are not formed at all. As a rule, the swallowing develops on the plant gradually - first the disease affects only a few branches, and only with the years the entire bush. Unfortunately, there are no varieties that would be resistant to this disease.

You need to fight with the sword in the following ways. Attentive to planting material - use cuttings only from those plants on which for three years there were no symptoms of this disease. At the end of flowering, carefully inspect the bushes. If an affected plant is found, then uproot the whole bush and burn it. You can cut their individual diseased branches, when the disease has only begun to develop. But there is no guarantee that it will not start again.

These are the main diseases of the currant and their treatment. As we see, it is possible to save the plant in most cases, the main thing is to pay attention to the manifestation of the symptoms of the disease in time and to take up the treatment of the "patient".
