Abstract

The harmfulness of American powdery mildew (Sphaerotheca mors-uvae (Schwein.) in the fruiting plantations of black currant (Ribes nigrum L.) consists of the defeat of leaves, shoots and berries. 17.3 %. Under the action of the pathogen, growth points and shoots stop growing, internodes are shortened, leaves become small, fragile, chlorotic, often ugly. Berries crack and crumble unripe along with diseased leaves. Damage to berries entails a direct decrease in productivity.The phytopathological situation can be improved by using less affected varieties. Breeding for disease resistance is currently one of the priority areas in the selection of berry crops.
