Abstract

Groundnut is regarded as “King of oilseed crops” on account of its diversified uses. It’s productivity is challenged by several biotic and abiotic stresses. Sclerotium rolfsii Sacc. is one of the major constraints to groundnut production which causes a yield loss of about 25 – 80 %. Hence, the roving survey was conducted during Kharif 2021 in North-Eastern Karnataka region. The mean stem rot incidence among the different districts surveyed ranged between 18.89-36.28 per cent. The maximum stem rot incidence was recorded in Vijayanagar (36.28 %) followed by Ballari district (32.83 %). Whereas, minimum stem rot was recorded in Koppal district (18.89 %).
