| 摘 要： | 为筛选2.5%溴氰菊酯水乳剂防治烟青虫最适合的浓度,明确其防治效果,采用田间药效试验进行研究。结果表明:2.5%溴氰菊酯水乳剂对烟青虫有良好的防治效果,施药后虫口减退率及防治效果明显,在150600 ml/hm2用量下,虫口减退率为58.78%600 ml/hm2用量下,虫口减退率为58.78%86.17%,防治效果为61.37%86.17%,防治效果为61.37%91.04%。对照药剂与试验药剂防治效果无显著性差异。

| Abstract: | The Lambda - cyhalothrin 2.5 % ME was studied to against the Helicoverpa assulta throughout field trials. The results showed that, the Lambda - cyhalothrin 2.5 % ME had good control effects. There had an obviously change in the density decrease and relative efficacy. The density decrease was 58.78% - 86.17% , the relative efficacy was 61.37% - 91.04% under the application concentration of 10 -40 m]/mu. There was not significant difference between the control pesticide and Lambda- eyhalothrin 2.5% ME. The experimental Study offered test da- ta and reference frame to control H. assulta. |
