In order to the effectiveness of tank mix application of dual and broadleaf herbicides to control weeds, a field experiment was conducted at the Islamabad research station, Kermanshah, Iran, during 2014-2015. Treatments consisted of the application of (Mesosulfuron - methyl + Idosulfuron – methyl + Mefenpyr diethyl), (2,4D + MCPA), (Bromoxynil + MCPA) and (Mesosulfuron -methyl + Idosulfuron – methyl + Diflufenican + Mefenpyr diethyl) at different rates and tank mixing together.Treatments were arranged in a randomized complete block design with four replications.Results indicated that tank mix application of (Mesosulfuron - methyl + Idosulfuron – methyl + Mefenpyr diethyl) in combination with(Bromoxynil + MCPA)desirable controlled C. pycnocephalus, G. tricornutum, C. oxycanta and S. arvensisand reduced their density between 74% to 100% compared to control without spraying, while the single treatments controlled these weeds between 40% to 73%.Application of tank mix (Mesosulfuron - methyl + Idosulfuron – methyl + Mefenpyr diethyl) in combination with (Bromoxynil + MCPA)at rates 0.5 + 1.25 and 0.25 + 1.25 increased wheat grain yield at rates1927 (155%) and 2031 (158%)kg/ha respectively, compared to control without spraying, as well as weight of 1000 grain above herbicides increased at rates 44 (198%) and 45 (198%) gr respectively
