Among them, the main place is occupied by temperature. In 2024-2025, the growth and development of the fungus was studied in laboratory conditions on various nutrient media and at different temperatures of -18-20°C; 22-24°C and 32-35°C. It was found that the best growth and development of the Botrytis cinerea fungus was determined on potato agar and oatmeal agar at a temperature of 22-24°C, at which the daily increase reached 37-39 mm.
