| 摘 要： | 草坪禾草腐霉病是由腐霉菌（ Pythium sp.）引起的一种真菌病害，可以为害禾草各个生长时期的任何部位，造成植株褐变腐烂或枯死，湿度大时可产生大量白色或紫灰色棉絮状菌丝体，持续高温高湿条件下能在很短的时间内破坏大片草皮。土壤、灌溉水雨水、病残体、器械工具和人、动物等都可携带传播。以游动孢子产生的休止孢子萌发出芽管、侵染丝或卵孢子直接产生的芽管及侵染丝侵入寄主为害。主要防治措施是选好用地，改良土壤，加强肥水管理，种植抗耐病品种，或不同品种混种，药剂防治包括土壤处理、种子处理和药剂喷洒等措施。

| Abstract: | Pythium disease of grass lawn is a disease, effected by pythium spp, which could harm all parts of grass during all growth periods, cause plant brown, rotten or wilt plant. When humidity is high, can produce a lot of white or purple－ grey fibred hyphan. When humidity and temperature are all high, these pathogens can damage a large piece of sod. Soil, irrigation water, rainwater, tools of production, people and animals all can carry and spread the disease. The main management to control the disease include: improve the soil, enhance the management of irrigation and gertillize, plant resistant verifies or different varieties, chemical control, including soil treatment, seed treatment and spraying etc |
