Abstract
Fusarium leaf blight and wilt of groundnut is a new emerging fungal disease particularly of kharif season in western Rajasthan, India. Fusarium spp. has wide host range causing wilts, blights and necrosis of numerous crops. This disease significantly affects groundnut haulm and pod yield and their quality. This disease occurs in patches at later stages of groundnut crop and their severity is varying from 5-52% at farmers’ field. In disease management practices, now effective chemical control measures are not available but efforts are being done for the control of this disease through various combinations of fungicides in addition to bio-control measures, cultural practices and host plant resistance. Now efforts are being done to identify resistance source for developing high yielding groundnut cultivars with resistance of Fusarium leaf blight and wilt.
