摘　　要：对北京市海淀区部分草坪的病害种类调查表明:草坪的病害主要是由丝核菌属、腐霉菌属、镰刀菌属引起的褐斑病、腐霉枯萎病和镰刀枯萎病。在初筛的基础上进行的室内筛选结果表明:嘧菌酯、咪鲜胺和苯醚甲环唑对供试的3种病原菌的抑制效果最佳,噁霉灵和多菌灵次之,而三唑酮对于立枯丝核菌的抑制较强,甲霜灵(该药不宜使用单剂,易产生抗性)对腐霉菌和镰刀菌的抑制较强。The main diseases of some turfgrass in Haidian were investigated. The results indicated that the main turfgrass diseases were brown patch, pythium and fuarium diseases. Their pathogens were Rhzoctonia, Pythium and Fusarium respectively. The results of fungicide screen in laboratory showed that the inhibition of difenoconazole, prochloraz and azoxystrobin to the three pathogens were strong and carbendazim and hymexazol were less. The inhibition of triadimefon to Rhizoctonia was strong and to the others was less. The inhibition of metalaxyl to Pythium and Fusarium were strong and to Rhizoctonia was less.
