Weeds are one of the most important factors that impose a great threat to crop yield. In order to alleviate weed infestation in wheat (Triticum aestivum L.), efficacy of various doses of ACM 9 were tested during Rabi 2010 to 2011 at Norman E. Borlough Crop Research Center, Pantnagar, Uttarakhand. Results revealed that ACM 9 applied at 1000 and 1200 g/ha severely reduced total density and dry weight of weeds as compared to control, while poor weed control was achieved using clodinafop 400 g/ha and metribuzin 300 g/ha. Highest grain yield of wheat was recorded with ACM 9 at 1200 g/ha (4.09 t/ha) during 2010 while in 2011, it was with ACM 9 at 1000 g/ha (4.16 t/ha). Post-emergence application of ACM 9 at 1200 and 1000 g/ha caused increase in wheat yield (18.2 and 97.4% during 2010 and 2011, respectively) over control.
