We consider the currant not only an unusual berry taste. In addition to the special "sourness", currant is appreciated for the medicinal properties and high content of vitamin C. You can be sure of the absolute quality of the berry if you grow it yourself. Unfortunately, on the way to the goal there can be various obstacles in the form of pests or diseases. One of the most common problems is red spots. It's about how to get rid of the red spots on the currant leaves.
Combating anthracnose
One of the reasons why there are red spots on the currant leaves, can be anthracnose. To define it is not difficult - the leaves are covered with small dark red specks, which eventually grow into spots. The measures to combat anthracnose include the cutting off of spoiled leaves and the digging of the near-barrel circle. At the initial stage of the disease development the bushes are sprayed with the biological preparation "Phytosporin" or with Bordeaux fluid. In severe cases, use "Nitrafen" or "Homicin".
Combating rust
This disease, caused by spores of the fungus, is manifested by the appearance of blistered warts of a reddish-orange color. If we talk about what to do if you find red spots on the leaves on the currant, then the first thing to do is to rip all the affected parts and burn them. Control measures also include spraying with any of the following solutions:
- Bordeaux liquid 1%;
- copper sulfate 1%;
- colloidal sulfur 1%.
In addition, in how to deal with red spots on the currant leaves, it is important to carry out preventive procedures. Osoka is one of the frequent vectors of fungus spores, therefore, at the site where you grow bush, you should permanently remove any species of sedge.
Fighting aphids
A dangerous pest settles on the inside of the leaves and begins to feed on their juice. As a result, the leaves twist, and on their outer side appear red growths - galls. Treatment of the disease of the currant, when the leaves are red spots, reduces to the destruction of parts of shrubs. Spraying is also shown. You can use home remedies, for example, by preparing an infusion of 400 g of wood ash and 400 g of tobacco diluted in a bucket of water. Effective special chemicals - insecids. These include "Rovikurt", "Carbophos", "Aktara" and others. Such treatment is carried out several times a season - early in the spring, before the buds dissolve, then with the development of leaflets, and the last time in the summer.
