Abstract
A field experiment was conducted during the kharif season of year 2000–2001 to evaluate the bio-efflcacy of new herbicide YRC-2388 (Fentrazamide) 50 WP againstweed flora in transplanted rice. YRC-2388 at 120 g/ha and pretilachlor 1000 g/ha applied 3 OAT brought about 87 and 90% in 2000 and 95 and 96% in 2001, respectively reduction in OW of weeds over weedy check. YRC-2388 applied at 3 OAT proved significantly superior over its late application (8 OAT) in controlling the weeds. Aufenacet at 240 g/ha had phytotoxic dfect on crop and reduce the grain yield of rice during both the years. YRC-2388 at 120 and 150 g/ha and pretilachlor at 1000 g/ha were at par with weed free treabnents in producing effective tillers and grain yield of rice. YRC-2388 at 150 g/ha applied at 3 OAT provided 18% and 24% higher grain yield as compared to applied at 8 OAT at the same dose during 2000 and 2001, respectlvely.
