Efficiency of mesosulfuron-methyl and clodinafop-propargyl dose for the control of Lolium perenne in wheat

► L. perenne biomass was totally different in pure stand and in mixed planting system, irrespective of the herbicide effect. More than 3-fold decrease was caused in the L. perenne biomass by the presence of wheat. ► Mesosulfuron-methyl was more potent than clodinafop-propargyl in the L. perenne control. ► The wheat grain yield received no benefits from applying mesosulfuron-methyl at the full recommended dose rather than the half-rate applications.
