The paper presents the study of the effect of fungicides solutions on the germination of conidia of fungi Cercospora beticola Sacc. and Alternaria alternata (Fr.) Keissl. It was found that inhibition of spore germination with fungicides had significantly depended on the duration of storage and the origin of the fungal isolates. Conidia of C. beticola were less resistant to the action of fungicides than spores of A. alternata. Fungicides Derozal and Alto Super were shown to be the most effective against the germination of spores of Cercospora leaf spot pathogen, while Alto Super — against the Alternaria spot disease.
