Casual organism of bacterial diseases of wheat at impact of abiotic factors

Abstract

Goal. Determine the sensitivity of pathogens of bacterial burn, spot, basal and black wheat bacteriosis to pesticides. Methods. Microbiological, statistical. Results The absence of a clear antibacterial effect of the insecticides and herbicides studied on bacterial pathogens of wheat has been established. It is shown that the studied phytopathogenic bacteria exhibit greater sensitivity to pesticides in a liquid nutrient medium than on agar. Conclusions Phytopathogenic bacteria exhibit polyvalent sensitivity to pesticides, even within the same species. The action of a pesticide depends on the active substance, its concentration and the nutrient medium. Most of the pesticides studied do not completely inhibit the development of wheat bacteriological pathogens, therefore the necessary condition is further testing of these drugs to detect other possible effects on phytopathogens and their properties.
