​This presentation provides an overview of Verticillium wilt of potato. It is intended to help growers, consultants, and students to better understand the epidemiology and management of the disease. The presentation shows representative color images of disease symptoms, describes the disease cycle, and discusses disease management strategies. Sources of initial inoculum, development of the pathogen within plants, and development of the disease in fields are discussed. A distinction is made between Verticillium wilt and potato early dying.
