Sheath blight of rice caused by Rhizoctonia solani Kuhn is emerging as very destructive disease causing heavy yield losses. This experiment was conducted at Department of plant Pathology, College of Agriculture, Rewa (M.P.) during 2018-19. This experiment was carried out in a complete randomized design (CRD) with eight treatments including untreated control. Seven fungicides viz., Flusilazole12.5%+carbendazim 25% SC, Azoxystrobin 18.2% w/w+difenoconazole 11.4 w/w SC, Azoxystrobin 11%+Tebuconazole 18.3% w/w SC, Tricyclazole 18%+ mancozeb 62%WP, Zineb 68% + hexaconazole 4% WP, Trifloxystrobin 25%+Tebuconazole 50%WG, Mancozeb 50%+carbendazim 25%WS, were evaluate against R. solani of rice at different concentrations under in-vitro by poisoned food technique. The present study, among the tested fungicides Azoxystrobin 11%+Tebuconazole 18.3% w/w SC at 200 ppm and 100 ppm was found significantly superior in inhibiting the mycelial growth of R. solani over untreated check at 96 hrs. after incubation.
