Abstract
In the conditions of the Krasnodar Territory, the pre-sowing treatment of seeds with drugs against diseases has firmly entered the system of protection of winter wheat. The use of seed dressing agents minimizes the risk of reducing field germination, ensures good overwintering of the crop, while being one of the most environmentally friendly plant protection methods. The idea of the biological efficiency of the seed disinfectants applied in the conditions of the region will allow not only to purposefully select a disinfectant, but also to prevent the resistance of pathogens causing diseases of seeds. An analysis of the range of fungicidal disinfectants used in the Krasnodar Territory in 2019 showed that the range was based on combined disinfectants based on several active substances with a different mechanism and spectrum of action, as well as that the shares of one-component and four-component drugs in it were - 10%, two-component - 20%. Combined dressers based on three active ingredients were the basis of the range used, the share of such preparations was 60%. Analysis of the data obtained allows to conclude that the modern range of dressing agents used in the farms of the Krasnodar Territory is capable of almost completely restraining the development of the pathogenic complex on winter wheat seeds. The maximum biological efficiency at the level of 100% was shown by the preparations in protection against dust and kernel smut, while it was at the level of 96.5% in protection against fusarium root rot.
Highlights
In the Russian Federation, a prerequisite for food security and independence is sustainable production of winter wheat grain, which ensures political and economic stability [9]

Summary
In the Russian Federation, a prerequisite for food security and independence is sustainable production of winter wheat grain, which ensures political and economic stability [9]. There can be a large amount of pathogenic microflora of various etiologies [3] on plant residues on the surface of the soil or in its upper layer, seed dressing is of particular importance. This is a preventive measure against internal and external seed infection. The research was aimed to study the biological efficiency of the seed disinfectant range used in the Krasnodar Territory, considering the pathogenic complex of winter wheat seeds formed during the years of research. - weather conditions during the growing season of winter wheat in 2018-2019; – study of the species composition of the pathogenic complex of winter wheat seeds of the 2019 harvest in the Krasnodar Territory; – study of the efficiency of the applied range of winter wheat seed disinfectants in the conditions of the Krasnodar Territory
