Abstract: Mungbean (Vigna radiata L.) is an important pulse crop in Indian continent. Mungbean is infected by several fungal, bacterial and viral diseases but foliar blight disease caused by Rhizoctonia solaniis considered as one of the most devastating diseases in the mungbean growing areas of Rajasthan. In the present investigation, effect of different range of temperature, pH, carbon and nitrogen sources with Czapex’s dox agar basal medium were evaluated under in vitro conditions against Rhizoctonia solani Kuhn. Maximum mycelial growth and sclerotia formation of pathogen was observed at 30 0C. While, minimum mycelial growth and sclerotia formation was at 20 0C temperature. Similarly, optimum pH for maximum mycelia growth and sclerotia formation of pathogen was 7.0. Maximum mycelial growth (68 mm) and sclerotia formation (32) of R. solani was observed on sucrose as compared to other sources. Among all the tested nitrogen sources, glutamic acid supported maximum mycelial growth (57.67 mm) and sclerotia formation (31) as compared to ammonium nitrate 65.50 mm and 36 respectively. Ammonium chloride was found least supportive to the mycelia growth and sclerotia formation 45.42 mm and 20 of the pathogen.
