The article presents the results of three-year field experiments on the effect of the seed treatment agent Vitalon, KS on the spread and development of root rot and bacteriosis in crops of common beans of new varieties bred by the Federal Scientific Center of Plant Breeding and the formation of their yield. The research yielded data that made it possible to determine the role of seed treatment with Vitalon, KS 2l/t in yield formation and reducing disease infestation of new vari- eties of common beans Markiza, Kupava and Strela under different weather conditions at different sowing dates. Using the method of conducting records during the growing season, the effectiveness of the seed treatment agent against bacteriosis (7.1 - 61.7%) and root rot of beans (9.9-70.7%) was determined. A reliable increase in yield on average by 11.2% over three years was revealed. Varietal differences and differences in the effectiveness of the drug depending on the sowing date were determined. On beans of the Kupava variety, diseases are more widespread in the second sowing period, but at the same time, it is in the second period that the Vitalon, KS preparation is most effective. With regard to other varieties of beans Strela and Markiza, the opposite pattern is observed: Vitalon, KS was more effective on beans of the first sowing period. This fact should be taken into account in the technologies of cultivating early-ripening varieties of beans and in the early stages of their sowing. It has been established that the rational use of the Vitalon, KS preparation allows to fully realize the potential seed productivity of common beans of the Markiza, Kupava, Strela varieties, increasing their resistance to diseases.
