| 摘 要： | 通过对20％曙唑酰草胺·灭草松ME防除水稻直播田一年生杂草及对水稻安全性的试验，明确了每667111。用20％嗯唑酰草胺·灭草松ME在有效剂量下，与10％韩秋好EC、48％灭草松AS相比较除草效果显著，杀草谱广；在水稻直播田中，当水稻秧苗2叶期后，杂草处于2～4叶期，用剂量为210—240mL／667m2（630—720a．i．g／hm2）时，能有效地防除水稻直播田一年生单双子杂草和异型莎草，证明了在水稻直播田应用吧唑酰草胺·20％灭草松ME对水稻是安全的。

| Abstract: | The selectivity of metamifop ＋ bentazone 20% ME for controlling annual weeds in direct - seeded paddy fields was studied. The herbicide mixture provided better control effect of annual weeds than metamifop 10% EC or bentazone 43% AS. Metamifop ＋ bentazone 20% ME effectively controlled annual monocotyledonous and dicotyledonous weeds and Cyperus difformis at 630 - 720 g a. i./hm2 at the 2 - leaf stage of rice seedlings, when the weeds were at the 2 - 4 leaf stage. The herbicide mixture was safe to the crop when used in direct - seeded paddy fields. |
