Evaluation of Chemical Fungicides Against Sheath Blight Disease of Rice in India

Sheath blight of rice, caused by Rhizoctonia solani Kuhn, is emerging as a very destructive disease that causes significant yield losses. The present study was conducted at experimental field of College of Agriculture, Rewa, (M.P.) during 2018-2019. The experiment was laid out in Randomized Block Design (RBD) with three replications. Seven fungicide namely 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 tested for their efficacy to manage the sheath blight of rice. All the fungicide were found to reduce the sheath blight disease significantly. It can be concluded that among the tested fungicides, Azoxystrobin 11%+Tebuconazole 18.3% w/w SC was found highly effective for controlling sheath blight of rice.
