Abstract
Web blight (Rhizoctonia solani Kühn) is one of the major diseases of mungbean. The mode of infection is soil-borne, seed borne and air-borne. Random survey was conducted during the kharif season (2022) to study the intensity of web blight in mungbean growing areas of Rajasthan which include Jaipur, Ajmer, Nagaur, Sikar and Tonk. The result showed that the disease intensity ranged from 15.70% to 31.04%. An average disease intensity of 23.57 % was recorded in the surveyed districts. The maximum intensity of web blight disease was recorded in Ajmer District (31.04%).
