Investigation revealed that out of seven chemicals tested carbendazim was found to be most effective in reducing both the incidence and severity of sheath rot (16.6 and 13.9 compared to 39.2 and 43.5 in check). The vigor index was highest (984) in treated seed compared to (544) untreated check. Germination percentage was 85%. The seed treatment also enhanced grain yield. This study indicated that seed borne nature of <i>Surocladium oryzae</i> and its adverse effect could be checked by use of carbandazim at 0.1%. 收起
