Rice is a monocotyledonous annual grass, and belongs to the family Poaceae. Sheath blight of rice is one of the major limiting factors in rice production. The causal agent of disease is Rhizoctonia solani. Seven fungicides were tested to know their efficacy against the pathogen under in-vitro and in-vivo. Among seven fungicides Hexaconazole 5% EC at 500 ppm was found to be highly effective followed by Captan + Hexaconazole under in-vitro condition which inhibit the fungal mycelium up to 93.66% and 89.77% respectively. Under in-vivo condition the maximum disease suppression was found in Hexaconazole treated plot followed by Captan + Hexaconazole.
