Currant is a useful plant, the berries of which are consumed fresh, jams and preserves are made from them, compotes are cooked. The leaves of the bush are used for making tea and in preservation. The appearance of red spots on the leaves is always a sign that trouble has happened to the culture.
Causes of spots
Red spots on currant leaves appear due to diseases and insect pests. To save the crop, it is necessary to recognize the symptoms in time and start the fight.
Anthracnose
A fungal disease that multiplies at high temperatures and high humidity. First of all, it affects the lower leaves of the bush. Initially, the spots are small, solitary, with time they merge into one large spot, painted in a brown tint. The leaf dries up, curls, falls off.
The disease is highly contagious and spreads rapidly throughout the plantings. The affected foliage must be removed and destroyed, as the fungus is able to overwinter on fallen leaves and attack the culture again next year.
Rust
Fungal disease that manifests itself in early June. The upper part of the leaves is covered with red bubbles, which, growing, lead to the fall of both the leaves and the ovaries of the berries.
By July, the underside of the foliage is covered in fluffy spores that are carried by the wind. If the disease is not treated, then the currant bushes will die.
Red gall aphid
Aphids feed on plant sap by piercing the leaf blade. Tubercles and swellings appear on the leaves. You can distinguish from fungal infections by looking under the leaves, insects can be seen with the naked eye.
The vital activity of the pest deforms the bushes, provokes their death. The red-gall aphid is able to carry the virus, which remains in the culture even after the complete destruction of the pest.

At the very beginning of the appearance of diseases and aphids, you can get rid of them using folk methods. The most popular are the following:
- garlic tincture;
- soap solution;
- iodine solution;
- soap and garlic mixture;

At more advanced stages, or if folk remedies do not have the desired effect, I recommend using chemicals. To combat diseases and insects, I use various means. Consultants in gardening stores will help you tell which one is right for you.
