Abstract. Highly dangerous diseases that can potentially cause potato crops epiphytotic were identified out of 80 ones of different origin and aetiology known on potatoes. The selection was based on a number of phytosanitary risk criteria, including biological risk (an efficiency of the life and infectious life cycles of pathogens, leading to economic consequences); diagnostic risk (a dangerous underestimate, including incorrect diagnosis and interpretation of diagnosis profiles); agroecological risk (a possibility of environmental disturbances and imbalances in agrocenoses); marginal risk (an influence on migration processes, an outcome of wars and revolutions); social risk (an influence on the fate of states, historical and scientific figures). The most dangerous are five diseases or their groups: potato blight, spindle tuber virus, bacteriosis, nematodes, and potato combined wilt (PCW). The causative agents of these diseases have a capacious biopotential, well adapted to potatoes. All of them show significant damage to potatoes, which led to severe economic, environmental, and social consequences. Crop losses caused by these diseases in Russia can range from 80% to 100%. The death of above-ground organs of potato due to the injury caused by these pathogens reaches 100% by the end of the growing season. All these diseases represent a systemic retrospective and modern problem for potato production. Their containment demands great efforts through the use of the entire known range of measures and means for plant protection. The microevolutionary processes of the causative agents of diseases mentioned above may be associated with global challenges to potato growing in the nearest future. These diseases are closely related to dangerous potato diseases such as virosis, Rhizoctonia blight, silver scurf, anthracnose, and skin necrosis of potato. However, their harmfulness is either understudied or requires clarification.
Keywords: potato (Solanum tuberosum L.); highly dangerous potato diseases; potato blight; potato spindle tuber virus; nematode disease of potato; potato bacteriosis; potato combined wilt (PCW).
