摘　　要：致病疫霉可引起马铃薯和番茄晚疫病,常造成巨大损失,生产中主要依靠抗病品种和化学农药防治。但因病菌生理分化明显、遗传变异迅速,已出现能克服现有全部抗病基因的菌株,且抗药性日益突出,致使该病难以完全有效地得到控制。发掘致病疫霉颉颃微生物,并研发安全、高效的微生物农药是当前的研究热点之一。结合笔者开展的研究工作,就近年来国内外对致病疫霉颉颃细菌的筛选、颉颃物质及其作用机制等进行了综述。同时,对该领域当前存在的一些问题和今后的研究重点进行了讨论,以期加快对致病疫霉颉颃细菌的利用。Phytophthora infestans caused late blight of potato and tomato, often caused a great loss. Resistant varieties and pesticides were current main measures for controlling late blight of potato and tomato. Because of obvious physiological differentiation and quick hereditary variation of P. infestans, some new strains with strong chemicals resistance appeared in many potato production areas could overcome existing resistance genes. Research progress on screening of antagonistic bacteria, active substances and action mechanisms on P. infestans in recent years at home and abroad was reviewed, and some problems in this field and research highlight in future were discussed, which could contribute to its utilizations.
