摘　　要：【目的】二化螟、稻纵卷叶螟和稻飞虱均是水稻穗期的重要害虫,为减少用药量和用工成本,以乙基多杀菌素、三氟苯嘧啶与助剂(激健)为桶混试验药剂,开展了对这3种害虫防治效果的研究。【方法】在江西省鹰潭市余江区锦江镇范家村,以早稻中嘉早17和晚稻泰优398为供试材料,进行田间防治试验。【结果】不同处理对稻纵卷叶螟均有优良防效(88.2%~95.7%);对于螟虫和稻飞虱发生均较重的田块,推广使用25%乙基多杀菌素WDG 20 g/667 m^2+10%三氟苯嘧啶SC 16 mL/667 m^2+激健15 mL/667 m^2组合进行防治,理论防效分别为91.6%和95.8%。【意义】研究结果为减少农药使用量、减轻农事操作,以及提高生产效率提供理论指导。[Purposes]Chilo suppressalis,Cnaphalocrocis medinalis,and rice planthopper are important pests during the rice panicle stage.In order to reduce the dosage and labor cost of controlling these three pests,Spinetoram,Triflumezopyrim and adjuvant(Jijian)were tank-mixtured to study the control effect on these three pests.[Methods]Early rice Zhongjiazao 17 and late rice Taiyou 398 were used to conduct field experiments in Fanjia Village,Jinjiang Town,Yujiang District,Jiangxi Province.[Findings]The results showed that all different treatments had high control effects on C.medinalis(88.2%-95.7%).The combination of 25%spinetoram WDG 20 g per 667 m^2,10%triflumezopyrim SC 16 mL per 667 m^2 and Jijian 15 mL per 667 m^2 was recommended to control C.suppressalis and rice planthopper in fields with serious occurrence.The theoretical control effects were 91.6%and 95.8%,respectively.[Significances]The study could provide theoretical guidance for reducing pesticide use,reducing agricultural operation and improving the production efficiency.
