COMPOSITION AND RATIO OF PHYTOPATHOGENS IN SOILS OF WESTERN SIBERIA

Studies conducted in different soil and climatic zones have revealed differences in the composition and proportion of the main phytopathogenic fungi that cause root rot of agricultural plants. In the subtaiga zone, species of the genus Fusarium prevailed, and in the steppe zone, the phytopathogenic fungus Bipolaris sorokiniana prevailed. In the southern and northern forest-steppe, the ratio of these pathogens was approximately equal.
