With the disease of stone fruit crops, their taste and presentation are lost, fruit storage periods and yield are reduced. The study of the bioecological characteristics of the main parasites is important for the correct and timely development of measures to combat them. The optimal temperatures for the growth of pathogen fungi in Uzbekistan were determined, which for Stigmina coprophilia were 20–25 °C and Monilia cinerea — 20 °C, and the optimum humidity of the mushrooms were from 60.0% to 95.0%. When ploughing diseased parts of stone fruit crops to a depth of 35 cm with a long shelf life (100 days), there was a slight growth of fungi causing shot-hole disease and brown fruit rot on the shoots, while in other parts of the plants their development was not recorded.
