Prevalence of wilt-root rot and their associated pathogens at reproductive phase in lentil.

A survey of 116 districts of nine lentil growing states covering 603 farmers' fields revealed a range of 0.7-9.3% mean plant mortality at reproductive stages in different lentil growing states of the country. The overall mean mortality was 6.3%. The main pathogens found associated with plant mortality at this stage were Fusarium oxysporum f. sp. lentis (62.0%), Rhizoctonia bataticola (25.2%) and Sclerotium rolfsii (9.8%). The minor involvement of 1.8% was that of F. solani, F. chlamydosporum. F. equisetii, and R. solani. For the first time a national scenario of lentil wilt-root rot incidence at the crucial reproductive stage and their associated pathogens is reported here. [ABSTRACT FROM AUTHOR]
