田间药效试验结果表明,3.2%高效氯氰菊酯·甲氨基阿维菌素苯甲酸盐微乳剂对十字花科蔬菜主要害虫甜菜夜蛾Spodoptera exigua(Hbner)、小菜蛾Plutella xylostella(L.)、菜青虫Pieris rapae(L.)和斜纹夜蛾Spodoptera litura(Fabricius)均具有优良的防治效果,并有较好的速效性和持效性。3.2%高效氯氰菊酯.甲氨基阿维菌素苯甲酸盐微乳剂20,25和30g/667m23个处理药后1d对甜菜夜蛾、小菜蛾、菜青虫和斜纹夜蛾的防治效果为60.67%～77.41%,药后3d的防治效果达81.82%～97.77%,药后7d的防治效果达83.74%～99.25%。3.2%高效氯氰菊酯.甲氨基阿维菌素苯甲酸盐微乳剂可以作为防治蔬菜主要害虫的有效药剂推广使用,推荐使用剂量为25～30g/667m2(12～14.4gai/hm2)。
The results of field trials showed that the insecticidal effect of 3.2% beta-emamectin benzoate microemulsion on Spodoptera exigua (Hbner), Plutella xylostella (L.), the major pests of cruciferous vegetables, , Pieris rapae (L.) and Spodoptera litura (Fabricius) have excellent control effects, and have good quick-acting and persistence. 3.2% beta-cypermethrin.Effect of emamectin benzoate microemulsion on beet armyworm, diamondback moth, cabbage worm and Spodoptera litura was 60.67% ~ 1 d after 20, 25 and 30 g / 77.41%. After three days, the control effect was 81.82% -97.77%, and the control effect was 83.74% -99.25% after 7 days. 3.2% beta-cypermethrin.Amethine eibraionine benzoate microemulsion can be used as an effective agent for controlling the main pests of vegetables. The recommended dosage is 25 ~ 30g / 667m2 (12 ~ 14.4gai / hm2).
