摘　　要：为了提高吡噻菌胺对黄瓜白粉病的防治效果,筛选增效配方,降低抗性风险,为其应用提供理论依据。采用常规喷雾法进行田间防效试验。田间试验结果表明,20%吡噻菌胺SC+10%多抗霉素WP对黄瓜白粉病防效突出,第1次药后7 d防效为84.39%,第2次药后14 d防效高达97.48%。20%吡噻菌胺SC+10%多抗霉素WP增效作用明显,可以在黄瓜生产中推广应用。20%吡噻菌胺SC+30%苯甲·嘧菌酯SC对黄瓜白粉病也有较好的增效作用,可降低抗性风险,作为备选或轮换使用的方案。This paper aimed to improve the control effect of penthiopyrad on cucumber powdery mildew, screen a synergistic formula, reduce the risk of resistance, and provide a theoretical basis for its application. The field trial was conducted by routine spraying method. The results of field trials showed that penthiopyrad 20% SC + Polyoxin 10% WP had outstanding control effect on cucumber powdery mildew. The control effects of it was 84.39% at 7 days after treatment for the first time and the control effects of it achieved 97.48% at 14 days after treatment for the second time. The synergistic effect of penthiopyrad 20% SC + Polyoxin 10% WP was obvious, which could be promoted the use in cucumber production.Penthiopyrad 20% SC+difenoconazoe·azoxystrobin 30% SC also had good synergistic effect on cucumber powdery mildew. To reduce the risk of resistance, it could be used as alternative or rotational options.
