霜霉病菌类
pathogens causing downy mildews

   引起植物霜霉病的一类真菌。属真菌门卵菌纲霜霉目霜霉科,是种子植物的专性寄生菌。营养体为无隔多核菌丝,无性繁殖产生孢囊孢子。孢子囊产生于具有一定分枝方式的孢囊梗顶端。
   霜霉菌主要是侵染双子叶植物,一些禾本科植物也可受害。霜霉病多发生在叶片上,病菌多从气孔侵入,菌丝在寄主的薄壁细胞间产生吸器,伸入细胞内吸取养分、水分而扩展。受侵染的叶片先是退绿,以后出现坏死斑,病菌扩展因受叶脉限制,病斑常呈多角形。如果侵染多汁肥厚的器官(嫩茎、花梗、花器)则引起组织的肿大畸形(如十字花科作物霜霉病)或器官的变态(如谷子白发病)。在湿度很高的情况下,病组织(常在叶背)常产生由病菌的孢囊梗和孢子囊构成的霜霉状物,呈白色至灰白色;淡紫色至紫黑色或黑色,依不同种类的霜霉病而异,是在田间识别霜霉病的重要特征之一。
    中国发生的霜霉病主要有:黄瓜霜霉病、十字花科作物霜霉病、大豆霜霉病、葡萄霜霉病、莴苣霜霉病、谷子白发病和玉米、水稻、小麦等的黄化萎缩病。防治霜霉病主要采取选育抗病品种,加强栽培管理和做好病害流行的预测,及时喷药防治;对禾谷类作物的霜霉病应采取抗病品种、轮作和种子处理等综合措施。防治霜霉病的化学药剂有:铜剂、一些有机硫剂、百菌清、乙磷铝和瑞多霉等。
