Object of research: mechanisms of interaction between rural and urban varieties. cultures from phytopathogenic fungi in agrophytocenoses of cultivated plants The purpose of research: determination of the viability of phytopathogenic micromycetes under the influence of exometabolites of cultivated plants in agrocenoses. Research methods: Microbiological, phytopathological, phytoimmunological, statistical. Results and their novelty. The influence of exometabolites of cultivated plants on the viability of phytopathogenic micromycetes was analyzed (analytical literature review). The effect of exometabolites of spring barley varieties on the formation of mycelial biomass of phytopathogenic micromycetes was determined. The effect of exometabolites of varieties/hybrids of soybean and spring barley on the formation of sporulation of phytopathogenic micromycetes was determined. Indicators of the influence of exometabolites of spring barley varieties on the viability of phytopathogenic micromycetes have been developed. The results of the study confirm that the indicated indicators, such as the growth rate of the fungus, the formation of mycelial biomass, the intensity of sporulation and the percentage of viable spores substantiate the influence of exometabolites of varieties on the viability of phytopathogenic micromycetes, which reveals ways to increase the ecological safety of agroecosystems.
