Abstract
Azimsulfuron was evaluated for its efficacy in controlling mixed weed flora in transplanted rice at HAU Regional Research Station, Karnal, India. Density and dry weight of grassy weeds in the plots treated with azimsulfuron were higher than pretilachlor 1000 g/ha except azimsulfuron 30 g/ha applied at 15 days after transplanting (DAT). Density of broadleaf weeds was significantly lower under all azimsulfuron doses when applied at 15 DAT compared to 25 DAT. All the treatments of azimsulfuron (10–30 g/ha at 15 and 25 DAT) provided excellent control of sedges, which were significantly better than pretilachlor and were as good as weed free check. Yields under azimsulfuron 30 g/ha at 15 DAT during 2006, and 27.5 and 30 g/ha at 15 DAT and 30 g/ha at 25 DAT during 2007 were statistically at par with pretilachlor. There was no phyto-toxicity of azimsulfuron on rice and also there was no residual toxicity on the succeeding crop of wheat during both the years of experimentation.
