摘　　要： 农用抗生素S024对棉花枯萎病菌和禾谷丝核菌具有明显的抗生作用。用10%的农抗S024发酵粗提液处理后,2种病原菌的细胞壁均被破坏,内含物外渗,液泡消失,菌丝体断裂,其生长能力被抑制,但是解除农抗S024的胁迫后,病原菌菌丝可恢复生长;同时,农抗S024对病原菌的孢子萌发也有一定的抑制作用。 Agriantibiotic S024 had strong antibiotic effects on Fusarium turcicum and Rhizoctonia cerealis. The mycelium cell membrane was damaged after treatment with fermenting liquor of S024 diluted 10 times, the release of soluble constituents and the disappearance of the vacuole could be observed too. S024 could make the pathogenic mycelium break so that the mycelium growth was inhibited, however, the treated mycelium grew normally again after S024 stress was removed. Germination of pathogenic spore was inhibited after treatment with S024.
