摘要

A field experiment conducted during dry seasons of 1996-97 and 1997-98 revealed that post-emergence application of ethoxysulfuron+anilofos (0.02+0.375 kg ha~(-1) at 10 days after transplanting (DAT) was statistically at par with hand weeding (twice) at 20 and 40 DAT in controlling weeds of transplanted rice effectively and the grain yields were also comparable. Butachlor 1.0 kg ha~(-1) at 5 DAT + 2,4-D Na salt 0.4 kg ha~(-1) at 25 DAT, pretilachlor 0.4 kg ha~(-1)at 5 DAT and oxadiargyl 0.1 kg ha~(-1) at 5 DAT were also promising.
