摘　　要：[目的]了解氯氟吡氧乙酸异辛酯对田旋花的防除效果以及对红枣的安全性和使用方法.[方法]采用不同浓度的288 g/L氯氟吡氧乙酸异辛酯乳油对田旋花茎和叶正、背面进行均匀喷雾.[结果]288 g/L氯氟吡氧乙酸异辛酯乳油防除哈密垦区枣园田旋花效果明显,在浓度800～1 000倍液的株防效达到94％以上,且对红枣树的株高、枝、叶、果实,座果率等参数无异常变化.[结论]288 g/L氯氟吡氧乙酸异辛酯乳油对红枣生长无影响,适合在生产上使用.[Objective] The aim was to study the control effect of fluroxypyr-mepthyl on bindweed in Jujube orchard field,the safety of fluroxypyr-mepthyl on the red jujube and using method.[Method] Different concentrations of 88 g/L fluroxypyr-mepthyl were sprayed.[Result]The results showed that using 288 g/L fluroxypyr-mepthyl in Hami Jujube orchard field bindweed control effect was obvious,at a concentration of 800 to 1 000 times the strain control efficiency reached 94％,and the height of the red jujube,branches,leaves,fruit,fruit rate and other parameters were not abnormal changes.[Conclusion] Fluroxypyr-mepthyl had no effect on the growth of red dates,and was suitable for using in production.
