Study of tank mix application of dual propose and broad leaf herbicides for weed control in wheat fields

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
