5%氯虫苯甲酰胺悬浮剂对甜菜夜蛾幼虫的防效研究

Control Effect of 5% Chlorantraniliprole Suspension Concentrate on Larvae of Spodoptera exigua Hübner

本文以毛豆为试验作物,研究了5%氯虫苯甲酰胺悬浮剂以及5%氯虫苯甲酰胺悬浮分别与1%甲氨基阿维菌素苯甲酸盐乳油、20%虫酰肼悬浮剂和150g/L茚虫威乳油混用防治甜菜夜蛾的效果。结果表明,与清水对照相比,施用5%氯虫苯甲酰胺悬浮剂处理甜菜夜蛾幼虫虫口密度明显减少,药后3~7d防效高达98.07%~99.55%;将5%氯虫苯甲酰胺悬浮剂与1%甲氨基阿维菌素苯甲酸盐乳油混用,能显著提高对甜菜夜蛾幼虫防效的速效性。说明使用5%氯虫苯甲酰胺悬浮剂与1%甲氨基阿维菌素苯甲酸盐乳油混用具有很好的开发前景。

In this paper,edamame was used as the experimental crop to study the effect of 5% chlorantraniliprole suspension concentrate on the control of Spodoptera exigua Hübner,and the effect of 5% chlorantraniliprole suspension concentrate mixed with 1% emamectin benzoate emulsifiable concentrate,20% tebufenozide suspension concentrate or 150 g/L indoxacarb emulsifiable concentrate to control Spodoptera exigua Hübner.The results showed that compared with the control,the larvae density of Spodoptera exigua Hübner significantly reduced by treating with 5% chlorantraniliprole suspension concentrate,and the control effect was as high as 98.07%~99.55% after 3~7 days.Mixing 5% chlorantraniliprole suspension concentrate with 1% emamectin benzoate emulsifiable concentrate could significantly improve the rapidity of control effect on Spodoptera exigua Hübner.Mixing 5% chlorantraniliprole suspension concentrate with 1% emamectin benzoate emulsifiable concentrate had a good development prospect.
