摘要 选择25种杀菌剂,在四川凉山安宁河谷地区开展田间试验,调查比较各药剂对当地温室种植的克瑞森葡萄上白粉病的防治效果。结果表明,在供试药剂中,对克瑞森葡萄白粉病防效相对较好且表现稳定的是50%己唑醇水分散粒剂与42.4%唑醚·氟酰胺悬浮剂,第3次药后7d的防效分别为58.5%、53.9%;35%氟菌·戊唑醇悬浮剂、12%苯甲·氟酰胺悬浮剂、80%硫磺水分散粒剂、99%噁霉灵原药、30%咪鲜胺微囊悬浮剂的防效居中,分别为50.0%、48.6%、46.7%、46.5%、45.1%,另据叶片叶绿素含量的测定结果,上述7种药剂对叶绿素也有较好的保护效果,因此建议可将其用于克瑞森葡萄白粉病的田间防治。供试的生物源杀菌剂持续性较差,不建议单独使用,可与化学药剂合理混用。
