In order to study of tank mix possibility and selective broadleaf herbicide efficacy of sugar beet, an experiment was conducted at three sites( Karaj, Mashhad and Oroumieh),during 1385, at a randomized complete block design with 25 treatments and 3 replications. Different combinations of chloridazon, phenmedipham, desmedipham, phenmedipham+desmedipham+ ethofumesat, metamitron, triflusulfuron-methyl, and clopyralid were used at two application doses(full dose and split dose). Weed population and biomass and visual damage of each combination on weeds and sugar beet were traits that measured. Results indicated that triflusulfuronmethyl +( phenmedipham+des medipham+ ethofumesat) had the most effect on weed populations and biomass in all sites. triflusulfuron-methyl +desmedipham was also another good combination. However, these treatments had no effects on Convolvulus arvensis. Among Treatments, chloridazon+ triflusulfuron-methyl and chloridazon+ ( phenmedipham+desmedipham+ ethofumesat) had a poor effects on weeds. These combinations had no good control on Amaranthus retroflexus, Chenopodium album and Convolvulus arvensis.
