Abstract A field trial was conducted to check the feasibility of using urea as an adjuvant with formulated carfentrazone ethyl + clodinafop-propargyl + metsulfuron- methyl (FMC X100) herbicide against the weeds of wheat. The experiment comprised of eight treatments namely, weedy check (control), hand weeding (two times), carfentrazone ethyl + clodinafop-propargyl + metsulfuron-methyl @ 500 g ha-1(commercial product dose) and@ 375 g ha-1 each with 1 and 2% urea solution. All weed control treatments showed significant effect in reducing the individual, total weed density and weed dry weight. However, maximum reduction in total weed density and weight was recorded with hand weeding and reduced dose (375 g ha-1) of herbicide with 2% urea as an adjuvant, respectively. The yield and yield components like spike bearing tillers, number of grains per spike and 1000-grain weight were significantly increased with different herbicide treatments compared with weedy check. More wheat grain yield (4.08 t ha-1) was obtained from carfentrazone ethyl + clodinafop-propargyl + metsulfuron @ 375 g ha-1+ 2% urea treated plot and the manual hoeing (3.99 t ha-1) than the weedy check (3.13 t ha-1). Maximum increase in wheat grain yield was 30.35% by the use of carfentrazone ethyl + clodinafop-propargyl + metsulfuron-methyl @ 375 g ha-1 + 2% urea solution. It is concluded that carfentrazone ethyl + clodinafop-propargyl + metsulfuron-methyl can be applied @ 375 g ha-1 + 2% urea solution to get maximum weed control and grain yield of wheat.
