Pomegranate wilt is a soil-borne disease relatively difficult to prevent. In this study, actinomycetes with strong antagonistic activity against pomegranate wilt pathogen were separated and screened from the soil samples collected from Yunnan Mengzi Wanmu Pomegranate Garden and Jianshui Pomegranate Garden. The indoor bacteriostatic radius of strain MZ12 against pomegranate wilt pathogen was 11 mm while the indoor bacteriostatic radius of strain MZ1 against pomegranate wilt pathogen was 7.25 mm. Combined with the characteristics, morphological observation and 16S rDNA sequence analysis of the two strains on identification medium, MZ12 was initially identified as Streptomyces cinnamonensis , and MZ1 as Streptomyces fulvissimus.
