摘要： 为有效控制杭白菊上蚜虫危害，进行安全性测定和田间药效试验来优化70%吡虫啉WDG防治蚜虫的应用技术。结果表明，70%吡虫啉WDG对不同品种杭白菊（‘金菊2号’、‘小黄菊’、‘早小洋菊’、‘异种大白菊’、‘麻城福田白菊’）具有很好的安全性。浙江和湖北的田间药效试验结果表明，70%吡虫啉WDG对菊花上的棉蚜、桃蚜、菊小管蚜等蚜虫具有很好速效性和持效性的防治效果；使用量为52.5ga.i./hm2时，喷雾1天后的校正防效即可达70%以上，喷雾3天后的防效达85%以上，喷雾7天后的防效达90%以上，喷雾14天后的防效仍维持在80%以上，且没有观察到对杭白菊和非靶标生物的不利影响。70%吡虫啉WDG适宜在杭白菊上登记防治蚜虫，可在生产上推广应用。

Abstract: To effectively prevent the attack of aphids on Chrysanthemum morifolium, safety tests and field efficacy trials were carried out to optimize the application technique of 70% imidacloprid water dispersible granule (WDG) for controlling aphids. The results of laboratory safety test showed that 70% imidacloprid WDG was safe to different Chrysanthemum morifolium varieties including‘Jinju II’ ,‘Xiao Huangju’ ,‘Zao Xiaoyangju’ ,‘Yizhongdabaiju’ ,‘Futian Baiju’ , etc. The field efficacy trials in Zhejiang and Hubei Provinces indicated that 70% imidacloprid WDG had rapid and persistent control effects on aphids such as Macrosiphoniella sanborni, Myzus persicae and Aphis gossypii. The correction efficacies were above 70%, 85%, 90% and 80% after spraying 52.5 g a.i./hm2 for 1 day, 3 days, 7 days and 14 days, respectively. And no influence was observed on Chrysanthemum morifolium and non-target organisms. The results supported that 70% imidacloprid WDG was suitable to register and use widely for controlling aphids on Chrysanthemum morifolium.
