摘要
乙草胺·吡氟乙草灵混剂防除稻茬油菜田杂草，对各种单、双子叶杂草的综合株防效和鲜重防效分别达８３．６～９１．０％、９２．１～９６．５％，其中对牛繁缕等阔叶杂草的株防效和鲜重防效分别为６８．１～７０．８％、７８．６～８２．６％，克服了稻茬油菜田长期单用吡氟乙草灵而导致的牛繁缕等阔叶杂草迅速上升，危害日趋严重的弊端。
As haloxyfop has been used in oil seed rape field for several years, the broad leaf weeds developed and become the main trouble. For this reason the experiments were carried out with the mixture of acetochlor and haloxyfop in rotational rape fields after rice harvest. The trial results showed that the mixture was effective to control monocotyledonous and dicotyledonous weeds.The plant and fresh weight reduced by 83.6～91.0% and 92.1￣96.5%, respectively. The mixture also effective to control Malachium aquaticum. The plant and fresh weight reduced by 68.1￣ 70.8% and 78.6￣ 82.6%, respectively.
