Field evaluation of new molecules against sheath rot disease of rice caused by Sarocladium oryzae

Abstract

Sheath rot disease of rice caused by Sarocladium oryzae. In this study, the 7 fungicides were tested against S. oryzae. The efficacy of fungicides on sheath rot was tested under field conditions. The Kresoxim- Methyl 40% + Hexaconazole 8% WG (Ayaan) found superior for reducing sheath rot disease intensity (18.15), gave highest grain yield (8840.00 kg ha-1), highest test weight of grain (19.06 gm), and also increase the healthy grain (84.80%) and reduced the discoloured (9.20 %) and chaffy grain (6 %).
