10%溴氰虫酰胺可分散油悬浮剂对蔬菜害虫的防治效果、使用技术和推广前景

Control,Application Technique,and Prospect of Cyantraniliprole 10% OD aganist Vegetable Pests

2009~2012年,对10%溴氰虫酰胺可分散油悬浮剂进行大田示范试验,结果表明该药剂对小菜蛾、豆荚螟、烟粉虱、蚜虫、黄曲条跳甲和美洲斑潜蝇等蔬菜害虫有优良的防治效果。当该药剂用量为有效成分15~27 g/hm^2时,其对小菜蛾、美洲斑潜蝇幼虫(若虫)药后7~10 d的校正防效可达95%以上,持效期可达20-30 d。当用量为有效成分21~27 g/hm^2时,药后9 d对豇豆豆荚螟的荚校正防效80%以上,虫校正防效90%以上。当用量为有效成分30~42 g/hm^2,对黄曲条跳甲成虫、幼虫无明显的防效,但药后10 d作物保护效果可达90%以上,并对黄曲条跳甲有良好的驱避和拒食作用。用量为有效成分40~60 g/hm^2时对烟粉虱若虫、成虫药后10 d的校正防效达90%以上,持效期可达20 d以上,对烟粉虱若虫的防效优于成虫;对蚜虫药后10 d的校正防效为99%以上,持效期20 d以上。同时对该药剂的使用技术和推广前景作了客观的评价。

The field and demonstration trials of four years showed that cyantraniliprole 10% OD had excellent good effect for controlling many vegetable pests, such as Plutella xylostella, Pieris rapae, Spodoptera litura, Etiella zinckenella, Bemisia argentifolii, aphids, Phyllotreta striolata and Liriomza sativae. When applied at 15-27 g（a.i.）/hm2, the correction control efficacy of the insecticide against Plutella xylostella, Pier＆ rapae, Spodoptera litura and nymph of Liriomza sativae at 7-10 days after application were over 95%, and the persistent period were 20-30 days. When applied at 21-27 g（a.i.）/hm2, the correction control efficacy of the insecticide against Liriomza sativae at 9 days after application were over 80%（pods） and 90%（pests）. When applied at 30-42 g（a.i.）/hm2, it was no significant control efficacy against Phyllotreta striolata, but the efficacy of crop protection was over 90% at 10 days after application, and it has excellent repellent and antifeedant effect on the pest. When applied at 40-60 g（a.i.）/hm2, the correction control efficacy of the insecticide against Bemisia argentifolii at 10 days after application were over 90%, the persistent period were over 20 days, and the effect for nymph much better than adult; the correction control efficacy of the insecticide against aphids at 10 days after application were over 99%, the persistent period were over 20 days. The application technique and prospect of cyantraniliprole 10% OD were also evaluated in this paper.
