摘　　要：In this study, the efficacy of the native isolates of Trichoderma species to promote the growth and yield parameters of cucumber and to manage Fusarium wilt disease under greenhouse conditions were investigated. Ninety native Trichoderma antagonists were isolated from Grassland and forest soil in different geographical regions of Inner Mongolia, China. Applications of T. cf. harzianum T1, T2, T3, T4, T5, T6, T7, TS, T10, T11 and T. atroviride （T9） exhibited the least disease incidence （by 0%） also the same strains shows 100% of relative control effect. Cucumber seedling treated with T. cf. harzianum （T2 and T1） isolates showed a significant stimulatory effect on plant height （by 13 and 14 cm respectively） and the highest shoot and root fresh weight were recorded by T. asperelloides （T27） and T. gamsii （T17） by 1.62 gm and 0.97 gm respectively, in comparison to untreated control and treated control （10 cm and 4 cm, 1.27 gm and 0.22 gm and 0.82 gm and 0.10 gm）. Therefore, the antagonist （T1, T2, T3, T4, T5, T6, T7, T8, T8, T10, and T1 1） is chosen to be the most promising bio-control agent for Fusarium oxysporum f. sp. Cucumerinum and further study have to be exploited for sustainable disease management program.
