摘　　要：论述了玉米茎腐病的优势病原菌、发病规律及其防治对策,阐明了玉米茎腐病的侵染机制是腐霉菌在高温条件下主要的初侵染原,而镰刀菌因其超强的定殖能力而进行二次侵染,两种病原菌侵染致病的主要活性物质为糖蛋白毒素。筛选功能菌株研制生防制剂和采取农业综合栽培措施将成为取代化学药剂防治该病的主要措施。This paper discussed the pathogens, disease regularity and prevention countermeasures of maize stalk rot, and elucidated that the infection mechanism of maize stalk rot is primary infection source of Pythium spp under high temperature. Fusarium occur secondary infection rely on its super colonization ability. The main active substance of two pathogens pathogenicity is glycoprotein toxin. Develop biocontrol agents through filtrate functional strain and take comprehensive agricultural cultivation measures will become the main methods to pollution and control this disease replace chemical agent.
