Black scurf disease on potato is causing an economically losses to the potato crops which causes both quantitative and qualitative damage occurs in potato production areas all over the world. The fungus limits the growth by forming cankers on sprouts, underground stems, and stolons, and makes tubers ugly by forming black scurf (sclerotia) on tuber surfaces. Black scurf is caused by Rhizoctonia solani which is a complex species, at least 13 related but distinct genetically anastomosis groups (AGs). AG-3 is the main cause of black scurf, on the tubers there is brown to black sclerotia that develop late in the growing season. Rhizoctonia solani is a soil borne pathogen. So for effective management of this disease, it is requires implementation of an integrated disease management approach and knowledge of each of its stages. It is managed by the integrated approaches such as cultural control viz;disease free tubers, crop rotation, organic amendments, soil moisture and management, harvesting time, biological and chemical control.
