黄瓜霜霉病由鞭毛菌亚门假霜霉属真菌侵害引起,是黄瓜生产中的主要病害,在黄瓜温(棚)室栽培中发生普遍。该病具有传播迅速、不易控制的特点,严重影响黄瓜产量和品质。霜霉威盐酸盐·氟吡菌胺悬浮剂对卵菌纲真菌引起的植物病害表现出了较好的防治效果,可应用于黄瓜霜霉病的防治。本文主要对霜霉威盐酸盐·氟吡菌胺对黄瓜霜霉的药效和对黄瓜的安全性进行试验,以明确使用剂量,同时筛选出防治效果较好的药剂与其交替使用。
Cucumber downy mildew caused by the flagellum subfamily Phyllostachys pseudoretica fungus attacks, is the main disease in the production of cucumbers, cucumber temperature (shed) room cultivation occurs generally.
