Evaluation of Fungicides against Sheath Rot Disease of Rice: An In vitro Study

Sheath rot disease of rice, caused by Sarocladium oryzae (Sawada) Gams & Hawksworth and causes severe yield losses have been reported up to 20-85 per cent. Therefore, some of the fungicides were tested for their efficacies against the sheath rot pathogen S. oryzae under in vitro condition. In present study ten fungicides were selected and tested against the pathogen for their anti-fungal activity, among the fungicide treatments Tebuconazole 25 EC, Tebuconazole 50% + Trifloxystrobin 25% WG, Propiconazole 25% EC, Isopyrazam 12.5% w/v EC, Flusilazole 12.5% + Carbendazim 25% EC were completely (100%) inhibiting the mean mycelial growth (00.00 mm) are followed by the treatment of Kresoxim methyl 40% + Hexaconazole 8% WG (12.66 mm), at 1000ppm.
