１９９１～１９９５年在吉林省六个地区主要栽培品种上采集１０１６个病株标样．经分离、鉴定及致病性试验重分离验证，明确在吉林省玉米茎腐病病原菌由（Ｆｕｓａｒｉｕｍｓｐ．）和（Ｐｙｔｈｉｕｍｓｐ．）组成．其中（Ｆｕｓａｒｉｕｍｇｒａｍｉｎｅａｒｕｍ）是吉林省的优势种．其次为（Ｆｕｓａｒｉｕｍｍｏｎｉｌｉｆｏｒｍｅ）和（Ｐｙｔｈｉｕｍｓｐ．）。病原菌的组成、分布存在区域间和年度间的差异。在吉林地区是以（Ｐｙｔｈｉｕｍｓｐ．）为优势种。提出玉米茎腐病的研究工作应立足于本生态区内进行，以求达到控制和减少该病害发生危害的目的． From 1991 to 1995, 1016 diseased strains were collected from the main cultivars in six regions of Jilin Province. The isolation, identification and pathogenicity test were re-isolated and verified. It was clarified that the pathogen of corn stalk rot in Jilin Province consisted of (Fusarium sp.) And (Pythium sp.). Among them, (Fusariumgraminearum) is the dominant species in Jilin Province. Followed by (Fusariummoniliforme) and (Pythiumsp.). Pathogen composition, distribution, there are differences between regions and between years. In Jilin area is (Pythiumsp.) Is the dominant species. It is suggested that the research on maize stalk rot should be based on this ecological zone in order to achieve the purpose of controlling and reducing the harm of this disease.
