草地贪夜蛾防治药剂田间试验示范效果

Control effects of the pesticides on Spodoptera frugiperda in field

为明确几种药剂对草地贪夜蛾Spodoptera frugiperda幼虫的田间防治效果,合理使用化学农药对草地贪夜蛾进行科学防治提供理论依据。对氯虫苯甲酰胺、氟铃·茚虫威、甲维·高氯氟、乙基多杀菌素、乙多·甲氧虫、虱螨脲、阿维·氯苯酰、氯虫·高氯氟、甲氨基阿维菌素苯甲酸盐等9种药剂进行了玉米和马铃薯田间防效试验。结果表明,9种药剂对两种作物上草地贪夜蛾幼虫均有一定毒杀作用,乙多·甲氧虫、乙基多杀菌素和氯虫苯甲酰胺可作为应急防控的首选药剂,氯虫·高氯氟、阿维·氯苯酰和甲维·高氯氟可作为应急防控药剂轮换使用。

In order to clarify the field control effect of several pesticides on Spodoptera frugiperda,the rational use of chemical pesticides on the scientific control of S.frugiperda provides a theoretical basis.In this paper,the field control effects of nine insecticides on corn and potato were studied,including chlorantraniliprole,hexaflumuron·indoxacarb,emamectin benzoate·lambda-cyhalothrin,spinetoram,spinetoram·methoxyfenozide,lufenuron,abamectin·chlorantraniliprole,chlorantraniliprole·lambda-cyhalothrin and abamectin-aminomethyl.The results showed that the nine insecticides had certain toxic effects on the larvae of S.frugiperda on the two crops,of which spinetoram·methoxyfenozide,spinetoram and chlorantraniliprole could be used as the preferred agents for emergency control,while chlorantraniliprole·lambda-cyhalothrin,abamectin·chlorantraniliprole and emamectin benzoate·lambda-cyhalothrin could be used as substitutes for pesticide alternation.
