Abstract

Finger millet (Eleusine coracana (L.) Gaertn) is one of the important millet crops widely cultivated across India and more than 60 per cent of its area is concentrated in Karnataka. Even though it is hardy in nature, it has been affected from many biotic and abiotic stresses. Among them, foot rot caused by Sclerotium rolfsii is becoming a major threat in recent years to the finger millet production under irrigated and high rainfall condition. A different stage of crop is more susceptible to disease over a period of time and it gives them intensity with which it affects the yield. To know the occurrence and distribution of the pathogen a roving survey was carried out during Kharif 2019-20 in the major finger millet growing regions of Southern districts of Karnataka. The survey data showed that, mean foot rot disease incidence varied from 4.34 to 42.14 per cent in different locations. The highest mean per cent disease incidence was recorded in the Mandya district (42.14%), followed by Ch
