摘　　要：通过八种农药田间防治桃蚜的试验得出:药后7d,1.8%的阿维菌素乳油防治效果最好,校正防效达100%;25%喹硫磷乳油1000倍液、10%吡虫啉可湿性粉剂3000倍液、5%啶虫脒可湿性粉剂2000倍夜、4.5%高效氯氰菊酯乳油2500倍液、2.5%功夫乳油1000倍液,校正防效分别为99.93%,99.69%,98.84%,97.78%,95.21%.以上药剂可在防治桃蚜时交替使用。Eight pesticides were used to prevent the myzus persicae in the field. The results showed： after seven days, the control effect of 1000 times of 1.8% avermectin emulsion liquid is the best; other pesticides were 3000 times of 10% imidaclopfid WP ,1000 times of 25% iainalphos emulsion liquid,2000 times of 5% acetaniprid WP, 2500 times of 4.5% eta - cypemethin emulsion liquid and 1000 times of 2.5% lambda -cyhalothrin emulsion liquid; these pesticides＇ control effect were 99.69% , 99.93% ,98.84% ,97.78% ,95.21% . Thus, they could be substituted to prevent myzus persicae.
