The antagonistic activity of five aquatic hyphomycetes, viz., Heliscus lugdunensis, Tetrachaetum elegans, Tetracladium breve, T. marchalianum, and T. nainitalense, against seven plant pathogenic fungi was studied using a dual culture technique. Inhibitory activity of tested aquatic hyphomycetes was determined by measuring the radial growth of plant pathogenic fungi on dual culture plates. Tetrachaetum elegans showed antagonistic activity against Colletotrichum falcatum, Fusarium oxysporum, Pyricularia oryzae, Sclerotium sclerotiorum, and Tilletia indica. Heliscus lugdunensis showed antagonism against only two plant pathogenic fungi, Rhizoctonia solani and Colletotrichum falcatum. Tetracladium breve, T. marchalianum, and T. nainitalense showed no response towards tested plant pathogenic fungi.
采用对峙培养技术研究了5种水生真菌，即鲁氏弯孢菌、秀丽四毛菌、短四枝孢、马尔查利四枝孢和奈尼塔尔四枝孢对7种植物病原真菌的拮抗活性。通过测量植物病原真菌在对峙培养平板上的径向生长来确定受试水生真菌的抑制活性。秀丽四毛菌对镰孢炭疽菌、尖孢镰刀菌、稻瘟病菌、核盘菌和印度腥黑粉菌表现出拮抗活性。鲁氏弯孢菌仅对两种植物病原真菌，即立枯丝核菌和镰孢炭疽菌表现出拮抗作用。短四枝孢、马尔查利四枝孢和奈尼塔尔四枝孢对受试植物病原真菌无反应。
