The aim of this investigation was to evaluate the effect of different abiotic factors on growth parameters of Rhizoctonia solani under laboratory condition. Among seven different media studied, the causal organism of sheath blight of rice grew well on Carrot Agar (CA) and Potato Dextrose Agar (PDA) media. It required optimum temperature of 26 ± 2 °C and pH 7 for the growth and sclerotia formation. The maximum radial growth of tested pathogen was noticed after 168 h of incubation period by producing 36.70 mm on Carrot Agar (CA) medium. The maximum sclerotia formation of pathogen was recorded at pH 7 after 144 hrs. of incubation period.
