以1.08× 104和5× 104菌落形成单位（cfu/g土）接种两个非致病性尖孢镰刀菌菌株（C5和C14），可显著降低黄瓜枯萎病的接种密度-发病率曲线的斜率。oxysporum F.胡瓜黑腐病菌（sp. cucumerinum）菌株C14比C5显著减少病害。一个三相机制与枯萎病的生物防治这些代理商。对厚垣孢子的萌发有显著的抑制作用。O. C5或C14（.）
Two nonpathogenic strains of Fusarium oxysporum (C5 and C14) introduced into soil at 1.08× 10 4 and 5× 10 4 colony-forming units (cfu) per gram of soil significantly decreased the slope values of inoculum density-disease incidence curves generated for Fusarium wilt of cucumber induced by F. oxysporum f. sp. cucumerinum. Strain C14 reduced disease significantly more than C5. A three-phase mechanism was associated with biological control of Fusarium wilt by these agents. There was a significant reduction in germination of chlamydospores of F. o. cucumerinum in the rhizospheres of cucumbers infested with C5 or C14 (...)
