摘　　要：为明确氟啶虫酰胺对桃蚜的防治效果和最佳用药剂量,在桃树上进行了10%氟啶虫酰胺水分散粒剂不同稀释浓度喷雾处理防治桃蚜的田间药效试验,为示范推广提供科学依据。结果表明,10%氟啶虫酰胺水分散粒剂药后1 d速效性一般,但药后3 d,在有效成分20、40、60 mg/L处理下的防效就分别达到78.9%、86.8%、91.8%;药后7 d防效均达93%以上;药后14 d,在20、40、60 mg/L处理下仍分别保持着94.2%、98.4%、99.2%的防效。氟啶虫酰胺持效性优异,可与速效性较好的药剂混配,用于桃树桃蚜的防治。The experiment was conducted to evaluate the control effects of flonicamid against Myzus persicae,select the best dosage,and provide scientific basis for demonstration promotion of the pesticide in field.The field efficacy test of 10% flonicamid water dispersible granule(WDG)spraying with different dilute concentration against Myzus persicae on peach was carried out.The results showed that the control effect of fluidinamide 10%flonicamid WDG was not ideal on the firsd day after spraying,but control effects of 20,40 and 60 mg/L treatments reached 78.9%,86.8% and 91.8% on the 3rd d,respectively.The control effects were over 93% on the 7th d after spraying.14 d later,control effects of 20,40 and 60 mg/L treatments remained 94.2%,98.4% and 99.2%,respectively.Flonicamid had long-last efficacy,which can be used for the control of Myzus persicae by means of mixing insecticide with good quick availability.
