摘要
采用M-18、运五(Y-5)、海燕650B型3种机型飞机同时喷洒525g hm^(-2)25%灭幼脲Ⅲ来进行3~4龄美国白蛾的防治,以比较不同机型的飞机对美国白蛾的防治效果。结果表明:M-18、运五(Y-5)、海燕650B三种机型的单位面积药滴着落量依次加大,防效依次增强,效果最好的是海燕650B机型。
Control experiments on Hyphantria cunea were sprayed with 25% ChlorbenzuronⅢat the doses of 525 g hm^(-2) by adopting M-18,Yun-5(Y-5)& Haiyan 650 Baircraft.Control effect of different aircraft types on Hyphantria cunea was compared.Result shows that the number of drops increase and the control effects enhance from M-18,Yun-5(Y-5)to Haiyan 650 B,the control effect of Haiyan 650 Bis much optimal.
