Field experiment was conducted during rabi 2000–01 and 2001–02 to evaluate the effect of mesosulfuron and iodosulfuron alone and their ready-made mixture for control of weeds in wheat. Ready-mixture of mesosulfuron+iodosulfuron at 15+3 g ha−1 provided effective control of weeds and produced effective tillers and grain yield of wheat similar to sulfosulfuron at 25 g ha−1 and the plots kept weed-free for the whole season. Mesosulfuron alone at 18.75 g ha−1 was at par with sulfosulfuron at 25 g ha-1 in reducing the density and dry weight of weeds. On an average, it reduced the dry weight of weeds by 90% over weedy check. Highest wheat yield (5220–5446 kg ha−1) was recorded in weed-free plots, which was statistically similar to that with sulfosulfuron (5195–5411 kg ha−1) at 25 g ha−1 and readymix of mesosulfuron+iodosulfuron (5152–5323 kg ha−1) at 15+3 g ha−1.
