boiling water or steam, open fire;
1% solution of Bordeaux mixture;
5% copper sulfate solution.

When the first leaves appear

Use drugs of biological origin or folk remedies. Properly treated bushes will form the ovary and produce a crop.

For the treatment of awakened pests and pathogens, use Fitol or another remedy.

Before flowering

Spring plants need treatment the most. Timely processed bushes form ovaries, give new shoots. Before flowering, blackcurrants are treated against insects that harm the future ovary.

During the fruiting period

With particular delicacy, they treat plants that are at the stage of fruiting.Some varieties ripen in July. But later species bear fruit in August. Such bushes cannot be treated with chemicals. Summer residents advise spraying currants in the summer with folk remedies.

When there are already berries, the bushes are treated with onion or garlic infusion. They do not harm humans or animals. During the ripening of berries, it is better to use biological preparations, in addition to treatment for diseases, some of them are top dressing.

When black currants bear fruit, they are treated with chemicals. The autumn procedure does not harm plants, it kills insects that are going to spend the winter on the bushes. Summer residents recommend spraying with complex preparations that destroy insects or pathogens. You can water the soil under the currant with a weak solution of manganese or Bordeaux liquid. The bushes will better prepare for the winter and will give a normal harvest in the future.

Untreated, black currants will produce less than expected yield, this will lead to the death of plants.
