| 摘 要： | 【目的】研究丙炔氟草胺与二甲戊灵混配剂的除草作用及对棉花的安全性,为新疆棉田杂草防除系统提供新方案。【方法】以二甲戊灵为参比对照,通过田间药效试验方法测定丙炔氟草胺单剂、丙炔氟草胺·二甲戊灵混配剂对棉田杂草的控制作用,评价药剂对棉花的安全性。【结果】34%丙炔氟草胺·二甲戊灵乳油在剂量175~200 mL/667 m2下对3种杂草的效果均较好,与对照药剂42%丙炔氟草胺悬浮剂相比,无显著差异,与对照药剂33%二甲戊灵乳油相比,优于该药剂。【结论】丙炔氟草胺·二甲戊灵混配剂的阔叶杂草的防除效果优于二甲戊灵,对棉花安全,可在新疆地区进行推广使用。

| 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. |
