摘要
应用GA 2 0 0型飞机超低量喷洒杀虫优和低量喷洒灭幼脲防治落叶松毛虫结果表明 ,两种药剂都具有高效、稳定、快速、持效的特点。杀虫优用药量 2 2 5kg/hm2 ,灭幼脲 1 5kg/hm2 (与水比例为 1∶10 ) ,能有效遏制松毛虫的大发生 ,同时对寄生性天敌影响不大。
The result of ULV spray of Shachongyou and low volume spray of chlorbenzuron against Dendrolimus superans with GA-200 aircraft showed both the pesticides were high effective,stable,rapid and lasting.Shachongyou at the dosage of 2.25 kghm^2 and chlorbenzuron 1.5 kghm^2 could effectively check the outbreak of pine caterpillars and had little effect on parasitoids.
