摘要

从蘑菇基质中分离得到黄曲霉、黑曲霉、哈茨木霉、青霉4株真菌。对这些真菌对三种植物病原菌即尖孢镰刀菌、罗氏菌核菌和炭疽病菌的生物活性进行了评价。菌株中，哈茨木霉对3种病原菌的拮抗活性最高，青霉的拮抗活性低于黑曲霉和黄曲霉。哈茨木霉对尖孢镰刀菌的抑制效果最高(71.75%)，其次是罗尔夫菌核菌(61.64%)和炭疽菌(57%)。南盟J.农业， 19(2): 73-84 (2021)

Biological Efficacy of Mycoflora Isolated from Mushroom Substrate Against Pathogenic Fungi

Four fungi isolates, Aspergillus flavus, Aspergillus niger, Trichoderma harzianum, Penicillium sp. were isolated from mushroom substrates and identified. Biological activities these fungi were evaluated against three plant pathogens namely against Fusarium oxysporum, Sclerotium rolfsii, Colletotrichum corchori. Among the fungal isolates, Trichoderma harzianum showed the highest antagonistic activity against all three pathogens, Penicillium sp. showed less significant antagonistic activity than Aspergillus niger and Aspergillus flavus. Trichoderma harzianum showed the highest inhibitory effect in case of Fusarium oxysporum (71.75%) followed by Sclerotium rolfsii (61.64%) and Colletotrichum corchori (57%). SAARC J.
