特点 仲丁威具有强烈的触杀作用,并具有一定胃毒、熏蒸和杀卵作用,作用迅速快,但残效期短。

适用范围 仲丁威对飞虱、叶蝉有特效,对蚊、蝇幼虫也有一定防效。

使用方法
1、水稻害虫的防治 稻飞虱、稻蓟马、稻叶蝉每亩用25%乳油100-200ml,对水100kg喷雾。 三化螟、稻纵卷叶螟每亩用25%乳油200-250ml,对水100-150kg喷雾。
2、卫生害虫的防治 防治蚊、蝇及蚊幼虫,用25%乳油加水稀释成1%的溶液,按每平方米1-3ml喷洒。

注意事项
1、不能与碱性农药混用。
2、在稻田施药的前后10天,避免使用敌稗,以免发生药害。
3、中毒后解毒药为阿托品,严禁使用解磷定和吗啡。
