Effect of Sulfosulfuron and Mesosulfuron+Iodosulfuron on Weeds and Wheat Yield

DMA by Phalaris minor and BLB was significantly more in unsprayed control than all other herbicide treatments. On an average, the per cent reduction in dry matter of P. minor varied from 26.19 to 30.69 in herbicide treatments over unweeded control at harvest. Increase in the dose of sulfosulfuron and mesosulfuron+iodosulfuron reduced dry weight of weeds in the decreasing trend over weedy check due to varied concentrations. The studies revealed that all doses of sulfosulfuron (25, 37.5 and 50 q/ha) and mesosulfuron+iodosulfuron (12, 18 and 24 q/ha) were at par with each other in terms of yield of wheat as these herbicides gave an effective kill of weeds.
