The most popular and affordable means to protect plants from fungal diseases are fungicides. Development of new products is aimed at preparation of the composition of several substances to achieve the effect of mutual enhancement of action. We used the grains of wheat (Triticum sp. variety Julius) and barley (Hordeum sativum variety Gloria), they were significantly infected with phytopathogenic fungi, which allows us to get reliable data on the effectiveness of active substances of fungicides. All wheat grains treated with fungicides were infected less than the control ones. Analysis of the effect of individual fungicides demonstrated that the fungi were more sensitive to fludioxonil, especially at doses of CF 0: 2 (56.7% of infected grains) and CF 0:4 (36.7% of infected grains) 5.0 and 10.0 g/t. After the treatment of cyproconazole, the smallest number of infected grains was obtained when grains were treated at a dose 5.0 g/t (80.0 % of infected grains). The fungistatic effect of cyproconazole (C) and fludioxonil (F) was greatest when ratios of C : F were 2.5:10; 5:10; 10:2.5; 10:5; 10:10 g/t.
