The geographical location and relief of the Krasnodar Territory determines a wide variety of agro-climatic and agro-technological conditions for the production of crops. On the territory of the Krasnodar Territory there is the largest part of agricultural land intended for the production of rice crops in Russia. Annual infection of rice plants with pathogenic Piricularia Orizae Cav. due to a wide range of strain diversity and indicates a significant dependence of the population genotype on the territorial distribution area. Therefore, the identification of zones that determine the conditions for the spread of blast within the population plays an important role in studying the dynamics of pathogen development in the territory of rice cultivation. The results of the research work showed that the Krasnodar rice growing area has a uniform landscape without sharp changes in the relief profile. The location of adjacent geographical objects affects the agro-climatic conditions of the southern part of the territory, which indicates the likelihood of isolation of the population of rice blast strains in the southern part of the rice growing area. An analysis of the agricultural zoning of the Krasnodar Territory showed the isolation of the southern part of the rice-growing territory according to the characteristics of the soil cover and the isolation of the conditions of agrotechnological measures. Features of the water regime of the irrigation systems of the Krasnodar Territory indicate the differentiation of the factors of infection and the spread of the pathogen on the basis of the isolation of irrigation flows. The territory has a clear division along the channels of the Kuban and Protoka rivers.
