This article presents the results of control measures against Botrytis cinerea fungi, which cause significant damage to the fruits of strawberry crops. In greenhouse conditions, the application of the fungicide Flusil 40 e.c. at a rate of 0.1 l/ha against gray mold disease in strawberries manifested 90.4% biological effectiveness. The disease prevalence was 2.8%, its severity was 1.3%, and the disease index registered at 2.05%. An average yield of 280 centners per hectare was achieved in the greenhouse. When the fungicide Flusil 40 e.c. was applied at a rate of 0.1 l/ha before flowering in open field areas against these diseases, the prevalence rate of the disease was 3.7% and its severity was 1.3%. Additionally, a biological effectiveness of 87.2% was achieved. This treatment created the potential to obtain an average yield of 124.6 centners per hectare.
