摘要 利用烟雾载药技术防治杨树食叶害虫,克服了因杨树树体高大等原因用常规喷药方式难以达到最佳防治效果。其中4.5%氯氰菊酯乳油,2.5%溴氰菊酯乳油(又名敌杀死)分别与柴油按1:10,1:20两种配比混合后放烟24 h,害虫校正死亡率分别达到100.00%、97.40%; 100.00%、98.27%。3.0%高渗苯氧威与柴油按1:10配比混合后放烟72 h,死亡率达到 90.40%。在生产中可大力推广,而且操作简便有效。 Experiment of mixture poisonous smoke against poplar leaf pests was made. The result showed it could overcome shortcoming of common spraying control method because of high tree trunk. All the poisonous smoke made by mixture 4.50% eypermethrin EC (or 2. 50% deltamethrin EC) and diesel oil 1:10 or 1 ) 20 had good effects. The respective mortalities of the pest were 100.00% , 97.40%. 100.00%. 98.27% in 24 hours, Substituted by 3: 0% fenoxycarb and diesel oil 1:10, the mortalities were 90.40% in 72 hours. The techniques are convenient and worth popularizing widely in the production.
