Summary:[ Objective] The paper was to develop a priority scheme for prevention and control of kiwifruit bacterial canker with biological agents. [ Method ] The inhibitory effect of Streptomyces sp. SY-L12 on the growth of Pseudomonas syringae pv. actinidiae were assessed using liquid co-culture and inhibition zone meth- ods. The control efficiency of Streptomyces sp. fermentation broth against kiwifruit bacterial canker was studied via potted trial. [ Result ] As Streptomyces sp. SY- L12 was incubated for 24 h, the growth inhibition rate of its fermentation broth on P. syr/ngae pv. actinidiae was 94.0%. The control efficiency of fermentation broth against P. syringae pv. actinidiae was the best of 85.4% in potted trial when Streptomyces sp. SY-L12 grew at 28~C, 150 rpm for 8 -9 d, better than that of control agent copper hydroxide. The control efficiency was improved as the agent was mixed with 1 mg/L chitooligosaccharide. [ Conclusion] Streptomyces sp. SY-L12 could effectively inhibit the growth of P. syr/ngae pv. actinidiae, and can be developed as biological agent against kiwifruit bacterial canker.
