5种新药剂对小菜蛾的田间防效评价

测定5种新型药剂对甘蓝上小菜蛾的防效，并对其田间的应用效果进行评价。结果表明：6％阿维·氯苯酰悬浮剂、14％氯虫·高氯氟悬浮剂、5％氯虫苯甲酰胺悬浮剂、20％氟虫双酰胺水分散颗粒剂等4种药剂药后3d的防效达到86％以上．药后14d防效达98％以上，持效期均达15d以上。4种药剂可快速有效地防治小菜蛾，同时还可以兼治菜青虫、斜纹夜蛾等其他害虫，对天敌等影响较小，对作物安全，可作为防治小菜蛾的首选药剂在大田使用。24％氰氟虫腙SC药后7d的防效达到86．15％，药效缓慢．可在害虫发生初期或虫口密度较低时使用。...

In this paper, five new pesticides were conducted against Pllutella xylostella on cabbage through field trail. The results showed that 6% Avermectin.chlorobenzene acid SC, 14% chlorobenzene＇Lambda-cyhalothrin SC, 5% Chlorantraniliprole SC, 20% flubendiamide WDG, had significant effect on Pllutella xylostella, with the control efficacy over 86% and 98% at third day and 14th day after the treaments. These pesticdes had a effective period more than 15 days in the fields. These pesticides could control Pllutella xylostella timely and effectively, while they had controlling to other pests sach as Pieris rapae and Spodoptera litura, and were safe on natural enemies and crops. Therefor, they were worth to select priority in the field. 24% Metaflumizon SC were slow
