- 1% solution of Bordeaux liquid;
- 5% solution of copper sulfate.
The next treatment is carried out in May, even before flowering.
When the first leaves appear
Use drugs of biological origin or folk remedies. Properly treated bushes will form an ovary and produce a crop.
For treatment from woken up pests and pathogens, use "Fitol" or another agent.
In the spring, plants need treatment most of all. Timely treated bushes form ovaries, give new shoots. Before flowering, black currants are treated from insects that harm the future ovary.
They treat plants that are at the fruiting stage with particular delicacy. Some varieties ripen in July. But later species bear fruit in August. Such bushes cannot be treated with chemicals. Summer residents are advised to spray currants with folk remedies in the summer.
When there are already berries, the bushes are treated with onion or garlic infusion. They do not harm either 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 the plants, kills insects that are going to winter on the bushes. Summer residents recommend sprinkling with complex preparations that destroy insects or pathogens. You can water the soil under the currants with a weak solution of manganese or Bordeaux liquid.

Without treatment, black currant will yield less than expected, this will lead to the death of plants.
