To evaluate some herbicides efficiency for broomcorn’s weeds chemical management under farm conditions, an experiment was carried out in randomized completely block design with four replications in Achachi village of Miyaneh region. The herbicides were Atrazine as pre-plant incorporated with soil + alachlor as pre-emergence, atrazine as pre-emergence + eradicane as pre-plant incorporated with soil, 2,4-D+MCPA as post-emergence + hand weeding, foramsulfuron as post-emergence, nicosulfuron as post-emergence, alachlor as pre-emergence, nicosulfuron as post-emergence, alachlor as pre-emergence + 2,4-D MCPA as pre-emergence + hand weeding, alachlor as pre-emergence, atrazine as pre-plant, and hand weeding was considered as control. Atrazin and 2,4-D+MCPA + hand weeding of narrow-leaf weeds were not differet significantly with control. Results revealed that application of atrazin and 2,4-D MPCA + narrow-leaf hand weeding had no significant difference with hand weeding in weed control and side-effect on the crop. Despite positive effect on weed controlling, atrazine + alachlor, atrazine + eradican, alachlor, eradican and 2,4-D were phytotoxic on broomcorn. The pre-plant application method was better than pre- and post-emergence methods. Based on the results, individual application of herbicides tested was more effective than their mixing.
