The information on the symptoms of diseased plants in during vegetation and the soil-climatic conditions most favorable for the disease is presented. Taxonomy, morphological, physiological, and genetic properties of its pathogen are described. Area of major harm caused by the disease on crops in the territory of Russian Federation and in neighboring countries was outlined.
