A field experiment was conducted during winter seasons of 1994–95 and 1995–96 to find out the effect of irrigation levels and post emergence application of diclofop-methyl on weed growth and yield of wheat. Experimental results revealed that there was significant increase in dry matter of grassy and broad leaf weeds with the increase in irrigation levels from one to six. Yield of wheat was significantly more with six irrigations at critical stages compared to one and three irritations. Post emergence application of diclofop-methyl at 1.0 kg/ha provided good control of grassy weeds and produced grain yield at par with isoproturon at 1.0 kg/ha. However, diclofop-methyl applied at different doses failed to control the broad leaf weeds significantly indicating its ineffectiveness against broad leaf weeds.
