Abstract

The article presents a study of the biological preparations Orgamika F (1.5-2.0 l/ha) and Orgamika S (1.5-2.0 l/ha) against powdery mildew and downy mildew of grapes. The best result was achieved with the use of the biological preparation Orgamika F (2.0 l/ha) against downy mildew: the biological efficiency was 65.3% on leaves, 66.1% on shoots, and 70.0% on grape bunches, and 63.1% against powdery mildew on leaves, 63.4% on shoots, and 70.2% on grape bunches. When using the biological product Orgamika S (2.0 l/ha) against grape mildew, the biological effectiveness was 75.2% on leaves, 81.3% on shoots, and 78.0% on grape bunches. The biological effectiveness against powdery mildew was 66.6% on leaves, 68.2% on shoots, and 67.3% on grape bunches.
