| 摘 要： | 由四川省化工研究设计院新合成的杀虫剂８９─１，对棉铃虫（末龄幼虫）的ＬＣ_（５０）为２３０±５．５ｐｐ，乐果乳油为６２５±６．４ｐｐｍ，８９─１的毒力高于乐果１．７倍。田间防治试验表明，３０％８９─１乳油７５０－防治棉铃虫效果令人满意，施药３天以后防效为８０％以上，１０天后防效为８６．４％，与当前防治铃虫的优秀农药２５％喹硫磷１０００×防效相当，大大优于４０％乐果乳油７５０×的防效。

| Abstract: | Lc_(50) of the new pesticide 89 1 to American bollworm,which was synthesized by Sichuan Design Institute for Chemical Industry, was 230±5.5ppm,1.7 time higher than those of dimethoate. The results of experiment of controlling in field indicated that effects of 30% 89 1(EC)at 700X was satisfied with 80% and 86.45% controlling effectiveness after three and ten days of spraying respectively, Which were simillar to those of Quinalphos (EC) at 1000 X and much higher than dimethoate(EC) at 750 x. |
