The demand for organic food has grown rapidly over the last 25 years in many countries of the world. Organic farming standards require the application of biological products of disease control. The article presents the material on studying the effectiveness of fungicides based on microbiological antagonists against sunflower diseases. We carried out the study in 2020-2021 at V.S. Pustovoit All-Russian Research Institute of Oil Crops (VNIIMK) (Krasnodar). We established that the fungicides Geostim Fit type E, WS based on microbiological antagonists did not reduce the germination of sunflower seeds and actively suppressed seed infection. Their effectiveness against Alternaria spp. reached 50-74 %, against Rhizopus spp. – 74–100 %, against bacteria – 76–80 %. Double treatment of sunflower plants with BFTIM, WS (different strains) reduced the frequency of bacterial blight to 37 %, of dry rot – to 60 %, of Alternaria blight – to 39 %, of Phoma rot – to 41 %, and of Fusarium blight – to 75 %. The application scheme of Geostim Fit E (G), WS; BFTIM (E), WS; BFTIM (Zh), WS showed the best economic effectiveness with a seed yield of 3.56 t/ha, net income of 122 910 rubles, and profitability of 311 %.
