Potatoes, due to their adaptability, yield and nutritional properties, and as an important component of diversified farming systems, have long helped reduce food insecurity and help improve household incomes in times of crisis and modern population growth. Among the important current issues and challenges in the potato industry, sustainable and environmentally friendly production is named among the main problems. A similar level of safety and quality can be achieved when using microbiological fertilizers and biological preparations, one of which is the drug «Flavobacterin». The purpose of the work is to study the nature of the effect of the drug «Flavobacterin» on the yield and quality of marketable potato tubers. The experiment included 3 varieties of domestic selection: Lyubava, Bronnitsky and Inspiration. A positive effect of the biological preparation «Flavobacterin» on the resistance of potato plants of the studied varieties to late blight was noted. Potato variety Bronnitsky, when treated with a biological preparation, demonstrated the highest resistance of tops and the lowest degree of late blight damage over all periods of studying the infection - 9 points. The highest yield was recorded for potatoes of the Bronnitsky variety when treated with a biological product – 38,6 c/ha with a marketability of 92%. In terms of starch content, the Bronnitsky variety stood out, the variant using the studied biological product – 17,8%, approaching the technical varieties. The lowest starch content in tubers was observed in the Lyubava variety in the control variant and amounted to 14,2%.
