“艾美乐”等4种杀虫剂对烟蚜的药效试验

Experiments on Control of Myzus persicae (Sulzer)with Admire, Imidacloprid, Aldicarb, and Omethoate

摘要: 进行了"艾美乐"、"吡虫啉"、"涕灭威"、"氧化乐果"防治烟蚜的室内和田间药效试验。室内校正死亡率分别为95.91%、94.35%、89.67%、85.42%;穴施防效: "艾美乐" 5、10、15g/667m², "涕灭威" 1 000g/667m²,分别为74%~84.86%,95%~96.15%,98.27%~98.6%和70.81%~89.9%。叶面喷施"艾美乐"2、4、6g/667m², "吡虫啉" 3 000倍, "氧化乐果" 1 000倍的防效分别为76.45%~99.52%,84%~99.95%,92.40%~99.98%,89.9%~99.78%和44.65%~83.87%。方差分析证明,各种药效差异极显著。

Abstract: Laboratory and field experiments on control of Myzus persicae (Sulzer)with Admire, Imidacloprid, Aldicarb and Omethoate were conducted.The results showed that 1)the corrected mortality of Myzus persicae (Sulzer)by applying the four pesticides in the laboratory were 95.91%, 94.35%, 89.67% and 85.42%, respectively;2)by hole applying, the control effects of Admire 70 WG at rates of 75g, 150g, and 225g per ha were 74%-84.86%, 95%-96.15%, and 98.27%-98.6%, respectively, and Aldicarb at rates of 15000g per ha was 70.81%-89.9%;3)by foliar spraying, the control effects of Admire 70WG at rates 30g, 60g and 90g per ha were 76.45%-99.52%, 84%-99.95%, 92.40%-99.98%, respectively, and one 3 000th dilution of Imidacloprid and one 1000th dilution of Omethoate were 89.9%-99.78% and 44.65%-83.78%, respectively. The variance analysis indicated that there were extremely significant differences among control effects of the four pesticides.
