为筛选出防治稻纵卷叶螟的高效低毒农药,对2%齐墩螨素等4种农药进行田间对比试验,试验表明:在第三代稻纵卷叶螟低龄幼虫孵化盛期,喷施2%齐墩螨素50ml/667m2,防治效果最高,达98.53%;其次为15%安打悬浮剂,15ml/667m2防效为95.36%;毒死碑80ml/667m2的防效为92.94%;18%杀虫双(250ml/667m2)+大功臣(20g/667m2)+敌杀死(16ml/667m2)的防效最低,为91.55%.2%齐墩螨素防治稻纵卷叶螟低龄幼虫效果较好,且对稻田养鱼影响小,在有稻田养鱼习惯的地区很有推广价值.

In order to select high-effect chemicals to control rice leaf-folder, four chemicals were tested in plots experiment. The experimental results show that in hatch-peak stage of the folder's larva, the application of 2% avermectins by 50ml/667m2 has the best effect (98.53%), the second one is "Anda" suspension concentrate agent and then the "Dusipi" and "Shachongshuang" compound. The avermectins has better effect, smaller impact on field fish culture, which is worth to be extended in districts of rice + fish cultivation.
