Abstract. Digitalization is one of the modern trends in the development of agriculture. It is aimed at increasing the productivity of the industry and optimizing the costs of financial and labour resources. An important step in the development and application of effective decision support systems in the field of plant protection against diseases is the mapping of territories by the degree of epiphytotic risk. Using a previously designed mathematical simulator and data obtained from meteorological stations located in various Russian regions, as well as the QGIS software package, we mapped the risks of epiphytotic conditions for potato late blight and the corresponding crop losses in Russia for 2019–2020. According to the results of the calculations, the most favourable conditions for the development of the disease in both seasons developed in the Northwestern and Far Eastern Federal Districts, as well as in most of the Central Federal District. The predicted level of yield losses was more than 20%. Unfavourable conditions for the development of the disease and low predicted losses (less than 10%) in both seasons were noted in the South and North-Caucasian Federal Districts, as well as in some southern regions of the Ural and Siberian Federal Districts. In other federal districts and regions, the levels of disease development varied by season. This information is necessary to understand the phytosanitary situation that has developed in recent years in the territory of the Russian Federation. However, the possibility of rapid forecasting the risks of late blight outbreaks is no less important for the early implementation of protective treatments for potato plantings. The employees of the All-Russian Research Institute of Phytopathology jointly with the Infometeos company have developed a geographic information system (GIS), which opens up opportunities for assessing the general late blight background, developing in real time in the territory of the country, determining the zones with the highest or lowest late blight risks, as well as using these data for making decisions on the use of protective measures.
