Sensitivity of pathogens of helminthosporiosis and fusarium rot of grain crops in the Kansk-Krasnoyarsk forest-steppe to seed protectants of various chemical composition

The article presents the results of studies on the sensitivity of pathogens of helminthosporiosis and fusarium rot of grain crops in the Kansk-Krasnoyarsk forest-steppe to seed protectants of different chemical composition. Objects of research: Bipolaris sorokiniana (21 isolates) and Fusarium spp. (41 isolates) isolated from wheat roots. To conduct the experiment, the following protectants were used: Oplot, Vial Trust, Vitaros, Lamador, Maxim. The results of the studies showed that the regional population of B. sorokiniana demonstrates high sensitivity to the drug Vitaros, moderate sensitivity to the drugs Oplot, Lamador and Maxim, and low sensitivity to the drug Vial Trust, and regional representatives of R. Fusarium demonstrate high sensitivity to the drug Vitaros, moderate sensitivity to the drugs Lamador and Vial Trust, relatively low sensitivity to the drug Oplot and almost complete resistance to the drug Maxim The most effective drug for use in the territory of the Kansk-Krasnoyarsk forest-steppe has been determined.
