| 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。

Application Technique of 70% Imidacloprid WDG Controlling Aphids on Chrysanthemum morifolium |
| |
| Abstract: | To effectively prevent the attack by 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, Futian Baiju, etc. The field efficacy trials in Zhejiang and Hubei provinces indicated that 70% imidacloprid WDG had rapid and persistent control effects to aphids such as Macrosiphoniella sanborni, Myzus persicae and Aphis gossypii. The correction efficacies were above 70%, 85% , 90% and 80% with the usage of 52.5 g a.i./hm2 after spraying 1 day, 3 days, 7 days and 14 days, respectively. And no influences were observed for 70% imidacloprid WDG to natural enemies and non-target organisms. The results supported that 70% imidacloprid WDG was suitable to register and use widely for controlling aphids on Chrysanthemum morifolium. |
