Abstract

The paper presents the data on a long term dynamics of the occurrence and development of moniliosis in cherry plants. It’s established that during the research the occurrence of blossom blight of cherry sprouts was 1,6–59,7 %, and fruit rot – 0,2–27,4 %. The development of cherry blossom blight doesn’t depend on the age of the crop. The biological efficiency of the copper fungicide Indigo, CS was studied. The biological efficiency of Indigo, CS applied in a dose of 3,0–5,0 l/ha to cherry amounted to in 2020: 77,8–88,1 % for limitation of blossom blight of sprouts, and 86,0–92,0 % for limitation of fruit rot; in 2021: 77,8–83,0 % and 88,3–92,0 % respectively.
