Efficacy of fungicides for the management of sheath rot disease in rice under in vitro and in vivo conditions

Sheath rot of rice is caused by Sarocladium oryzae. In this study seven fungicides were tested against S. oryzae. Maximum inhibition of radial growth was recorded at 500 ppm of hexaconazole, tebuconazole, tricyclazole and propiconazole. Comparative efficacy of fungicides on sheath rot was tested under field condition. Hexaconazole 5% SC (Contaf) treatment followed by Tebuconazole 250 EC (Folicur), Carbendazim 50% WP (Bavistin), Propiconazole 25 EC (Tilt), Saaf (Carbendazim 12% + Mancozeb 63% wp) and Mancozeb 75% WP (Indofil M-45) treatment significantly reduced the sheath rot intensity and increased the grain yield.
