5%高效氯氟氰菊酯·甲维盐EW对甘蓝甜菜夜蛾的田间防治效果
Control Effect of 5 % Lambda-cyhalothrin · Emamectin Benzoate EW against Spodoptera exigua Hubner on Cabbage
摘要
Abstract
[Objective] The aim was to evaluate the control effect of 5 % Lambda-cyhalothrin · Emamectin Benzoate EW against Spodoptera exigua Hubner on cabbage.[Method] The control effect of 5% Lambda-cyhalothrin · Emamectin Benzoate EW against Spodoptera exigua Hubner on cabbage was studied through field plot test design,and the safety of 5% Lambda-cyhalothrin · Emamectin Benzoate EW to the growth of cabbage and natural enemy insect was evaluated.[Result] 5% Lambda-cyhalothrin · Emamectin Benzoate EW at 6-9 g/hm2 of effective components or 120-180 g/hm2 of reagent dosage had good insecticidal effect on S.exigua after two days,and still had good effect after 10 days.The reagent had no bad influence on the growth of cabbage and natural enemy insect.[Conclusion] 5% Lambda-cyhalothrin · Emamectin Benzoate EW is a suitable reagent to control S.exigua,and had advantages of no damage to crop growth,high effectiveness and long persistent period.The suitable dosage of 5% Lambda-cyhalothrin · Emamectin Benzoate EW is 750-900 kg/hm2,and the suitable time of chemicals application is from the incubation peak period of egg to the peak period of low instar larvae.关键词
