| 摘 要： | 为了做好防治烟蚜药剂的推荐工作,我们在2003年和2004年做了不同用量的吡虫啉对烟蚜的防效试验。试验结果表明,使用1000倍、1200倍和1400倍的5%吡虫啉乳油在施药后第1d和第2d对烟蚜的防治效果均在99%以上,3个浓度之间差异不显著,而对照药剂1000倍的氧乐果乳油第1d和第2d的防效均小于70%,极显著低于吡虫啉的防效;施药后第7d吡虫啉乳油的防效基本上为100%,3个浓度之间差异不显著,而氧乐果的防效显著降低。

| Abstract: | For recommending more effective pesticide to control Myzus persica(Sulzer) ,the field contrast experiments of imidacloprid EC used in different levels were conducted in 2003 and 2004. The results showed that the relative control effects of imidacloprid EC at different dilutions of 1000,1200 and 1400 were over 99% in the first and second day after application, which were not significant differences, that the relative control effects of omethoate EC at a dilution of 1000 were less than 70%, which were significant different from imidacloprid EC;and that the relative control effects of imidacloprid EC were 100% approximately in the seventh day after application, which of omethoate EC reduced significantly. |
