Abstract: 【Objective】 To clarify the weed control efficacy and the safety to cotton in the hope of providing a new type of weed control system for cotton field in Xinjiang.【Method】 Pendimethalin as the reference control, the weed control efficacy of the combination of flumioxazin and pendimethalin on weeds in cotton field was measured by the field efficacy test method and the safety of flumioxazin·pendimethalin EC on cotton was evaluated.【Result】 At the dosage of 175-200 mL/667 m2, 34% flumioxazin· pendimethalin EC showed the better herbicidal activity against three kinds of weeds. There was no significant difference between 34% flumioxazin · pendimethalin EC and 42% flumioxazin suspension agent. Compared with 33% pendimethalin EC, 34% flumioxazin · pendimethalin EC showed stronger bioassay.【Conclusion】 The control effect of the mixture is better than that of the single agent. It is safe for cotton and can be widely used in Xinjiang.

Key words: cotton; weed; flumioxazin·pendimethalin; field efficacy
