摘　　要：[Objective] This study aimed to screen effective fungicide for prevention and control of apple powdery mildew. [Method] Field efficacy of six kinds of fungi- cides with 18 concentrations against apple powdery mildew was investigated. [Re- sult] 4 000-fold triflumizole WP exhibited the highest control efficacy of 82.96%, fol- lowed by 3 000-fold triflumizole WP with control efficacy of 77.75%, while 800-fold and 1 000-fold 70% thiophanate methyl WP exhibited relatively low control efficacy, which was both lower than 60%. [Conclusion] In actual production, 4 000-fold triflu- mizole WP and 3 000-fold triflumizole WP should be used alternately to control and prevent apple powdery mildew.[目的]筛选防治苹果白粉病的有效杀菌剂。[方法]以6种杀菌剂18种浓度处理进行苹果白粉病的田间药效试验。[结果]氟菌唑WP 4 000倍液的防治效果最好,为82.96%;其次是氟菌唑WP 3 000倍液,防治效果为77.75%;而浓度70%甲基硫菌灵WP 800倍液和1 000倍液防治效果较差,均在60%以下。[结论]在生产上建议以氟菌唑WP 4 000倍液和氟菌唑WP 3 000倍液交替使用。
