Sheath blight is a soil-borne disease caused by the fungus Rhizoctonia solani and one of the most economically significant rice diseases worldwide. Two year pooled results of field experiment revealed minimum disease intensity (11.8%) and maximum reduction (58.0%) , maximum yield of paddy (3750.7 kg/ha) and cost benefit ratio (1.75) from the treatment Pseudomonas fluorescens @ 2.0 l/ha as foliar spray which was at par with P. fluorescens @ 3ml/kg as seed treatment followed by 1.5 l/ha as foliar spray (PDI 10.3 and PDC 64.5%) with grain yield (3911 kg/ha) as compared to control. However, standard check with fungicide Hexaconazole 5% EC @ 2ml/kg as seed treatment followed by 1.0 l/ha as foliar spray gave minimum disease intensity (9.3%), maximum disease control (67.9%) and highest yield of paddy (3944 kg/ha) with highest cost benefit ratio (1.95).
