In order to investigate the effects of antagonistic and synergisitic and the possibility of tankmixture of some important broadleaf herbicides and micronutrients fertilizers in wheat fields an experiment was conducted in randomized complete block design with two-factors during 2009- 2010 in Mazandaran with four replications. The first factor was three levels of herbicides including 2,4-D+MCPA at 1.5 lit.ha-1, Bromoxynil+MCPA at 1.5 lit.ha-1 and tribenoron-methyl at 20 gr.ha-1 as comercial ingrendient. The second factor was seven levels of micronutrients including complete fertilizer "Liberl- BMX" containing micronutrients chelate of iron, zinc, manganese, copper, boron and Molybdenum at 1.5 kg.ha-1, complete fertlizer "Biomin 235" containig chelate of iron, Molybdenum, nitrogen, zinc, copper and manganese as at 2 lit.ha-1, complete fertilizer "Biomin 466-sp" containing iron, Molybdenum, nitrogen, zinc, copper, magnesium, cobalt and manganese at 1 kg.ha-1, fertilizer of chelate of iron "Liberl Fe" at 1 kg.ha-1, fertilizer of chelate of Manganese "Liberl Mn" at 1 kg.ha-1 and fertilizer of chelate of zinc "Liberl Zn" at 1 kg.ha-1. The fertilizers and herbicides were applicated in tnak-mixture in tiller stage of wheat. The results showed that among the herbicides were applicated in present study, the efficacy of Bromoxynil+MCPA to control of boradleaf weeds were partially better than 2,4-D+MCPA and tribenoron-methyl. Applied fertilizers had no negative effects on efficacy of three mentioned herbicides. Therefore, the tank mixtrue of fertilizers and herbicides used in the present study is possible. In addition, the tank-mixture of these fertilizers and herbicides had no deleterious effects on wheat and its grain and biological yields. Among the fertilizers, fertilizes containing Zn were the best treatment compare to others.
