BIOLOGICAL EFFECTIVENESS OF STRAZH KS FUNGICIDE AGAINST SCAB AND MONILOSE DISEASES OF APPLE

Abstract

In our 2020 study in apple orchards, we tested the development of scab and moniliosis apple diseases, as well as the fungicide Strazh KS (0.3-0.6 l/ha) in the fight against these diseases. According to the results of the experiment, the damage to the leaves by the scab disease was 12.0- 10.0%, and the damage to the fruits was 10.3-8.3%. While the development of the disease was observed in leaves 5.1-3.8%, and in fruits - 4.6-3.1%, infection with moniliosis was 7.3-6.7% in leaves, varieties and fruits, and progression of the disease - 3.1-2.3% in leaves, varieties, fruits. The biological effectiveness of the fungicide Strazh KS (0.3-0.6 l/ha), used against squid disease, was 87.0- 90.1%, while when using this drug against moniliosis disease, the biological effectiveness was 86.6 -91.0%.
