Collar rot of lentil (Sclerotium rolfsii Sacc.) is caused by the ubiquitous soil- born pathogen Sclerocium rolfsii and reported almost all over the world wherever lentil is grown. The survey of fourteen locations in seven lentil growing district of Chhattisgarh state (Raipur, Mungeli, Bemetara, Bilaspur, Kawardha, Baloda bazaar and Dhamtari) was made for the occurrence and severity of lentil collar rot. The maximum mean disease incidence was observed in Mungeli district and lowest in Dhamtri district. Forteen isolates of S. Rolfsii Were Isolated From disease samples collected from different locations. The survey for the occurrence and severity of lentil collar rot were undertaken at seedling and vegetative stage of the crop from fortune locations in seven lentil growing districts of Chhattisgarh state (Raipur, Mungeli, Bilaspur, Dhamrari, Balodabajar, Kawardha, and Bemetara,) during 2018 and 19.
