| 摘 要： | An antagonistic Streptomyces strain B28, isolated from the soil collected in Tianmu mountain of Zhejiang Province, was identified as Streptomyces diastatochromogenes by morphological , physiological & biochemical characteristics and 16S rDNA sequence alignment. Antagonistic study indicated that its secondary metabolite toyocamycin had an antifungal activity on the mycelial growth of seven species of plant pathogenic fungi. The results showed that toyocamycin possessed marked inhibitory activity against Rhizoctonia solani and the EC50 value was 0. 58 μg / mL. The effective of toyocamycin against Botrytis cinerea and Fusarium oxysporum f. sp. cucumerinum was much higher than that against Colletotrichum gloeosporioides, the EC50 value of
toyocamycin in inhibiting B. cinerea, F. oxysporum and C. gloeosporioides were 13. 65 μg / mL, 12. 33 μg / mL, and 30. 15 μg / mL respectively.
