3种药剂防治核桃举肢蛾效果研究

The Control Effects of Three Pesticides on Atrijuglans hetaohei Yang

为筛选防治核桃举肢蛾效果较好的杀虫剂,该试验选用毒死蜱、乙酰甲胺磷和杀灭菊酯3种杀虫剂对核桃举肢蛾进行试验。结果表明:试验选用的3种杀虫剂不同剂量处理对核桃举肢蛾均有一定的防治效果,其中40%乙酰甲胺磷乳油以1000倍液处理对核桃举肢蛾表现出了最高的防治效果,为92.11%;48%毒死蜱乳油1000倍液处理对核桃举肢蛾的效果次之,为85.35%;20%杀灭菊酯乳油以1500倍液处理的防治效果最低为76.27%。3种试验药剂中40%乙酰甲胺磷乳油和48%毒死蜱乳油以1000倍液处理对核桃举肢蛾的防治效果较好,适合在生产中推广应用。

This experiment studied on the control effects of three pesticides on Atrijuglans hetaohei Yang. Three pesticides,Chlorpyrifos, Acephate and Fenvalerate canopy spraying were conducted. The results showed that Chlorpyrifos, Acephate and Fenvalerate had different control effects on Atrijuglans hetaohei Yang. Acephate diluted 1000 times had the highest control effect of 92.11%, the control effect of Chlorpyrifos diluted 1000 times was the second with 85.35%, the effect of Fenvalerate was the worst among three pesticides. The control efficacies of Chlorpyrifos, Acephatewere up to 85.35% ~92.11%, and the two pesticides could be popularized in the production.
