Everyone wants to grow a redcurrant on his garden, and it is not difficult to do it. The berries of this shrub have a unique light taste and medicinal properties, which are attributed to the ability to help the body cleanse of toxins, as well as to treat stomach diseases.
But often care for the culture is complicated by diseases of the red currant, including red convex spots on the leaves. Let's find out what this attack is and how to fight it.
Why did the red currant appear on the currant leaves?
There are two reasons why a plant gets sick and we see maroon spots on the leaves of red currant - anthracnose and common aphids. In the first case, the disease can develop in several stages and redness - the very first of them, when you can still help the bush to cope with the disease.
If you miss the time, the leaves gradually become brown, curl and dry out. Thus, entire branches are affected and you can lose shrubs altogether. In addition, the berries lose their taste and become sour, small, which, undoubtedly, is not the result that the gardener expects from the harvest.
A more prosaic cause of the disease is a gall midge. If you notice that there are red spots on the currant leaves, turn the leaf with the back side up, and you can find whole colonies of these insects there. Day after day, they imperceptibly do their black work - sucking out of the leaf of its juice, leaving on site the damage of brown and red spots. As in the case of anthracnose without proper treatment, you can lose the bush.
Treatment of red spots on currant leaves
As is known, aphids are brought to the leaves by garden ants. If there are several anthills on the site, the aphids will not be able to avoid infection of plants. Moreover, the treatment of shrubs will only lead to a temporary improvement in the situation and after a couple of weeks, the aphids will again be in their places. This means that, first of all, it is necessary to throw all the forces into the struggle with the ants, because aphids are annoying not only the currant, but also the majority of the inhabitants of the garden and the garden. After the destruction of the anthills, one can start processing leaves from the aphids themselves. This is done with the help of chemical preparations or with
To defeat anthracnose, it can not be by soap alone. If it took place last season, it should be in the early spring to shed branches and kidneys with steep boiling water, and dig up the earth around and process with copper sulfate.
With the appearance of leaves with reddening, they are sprayed with Bordeaux liquid, and if they are severely affected, they are removed. In the autumn, all diseased parts of the plant should be burned and the soil treated again.
