The use of biological preparations in the protection of agricultural plants from diseases is of great importance. This issue is especially relevant in the production of potatoes. The research results showed that the pre-planting treatment of seed tubers with biological products Kartofin and BisolbiSan had a positive effect on the germination of potato tubers, increasing it in comparison with the control by 6.3-8.7%. In the field, they showed high biological effectiveness against pathogens of fungal diseases of potatoes: late blight, rhizoctonia (from 37.5 to 100%). The counts of the total yield showed that the highest yield indicators were observed in the variant with the use of the biological product BisolbiSan - 38.4 t / ha (20.5% higher than the control variant).
