Abstract

Abstract: To develop complex microbial agents against strawberry anthracnose, we compared the inhibitory effects of five Bacillus strains (strain CM3, Y-48, Lh-1, Y-30 and Y-9) on Colletotrichum thebromicoia with different combinations and proportions and identified the best combination. By using the pot culture experiment, we measured their control effects. Bacteriostasis experiment showed that the combination which was composed of Bacillus megaterium Y-30 and Bacillus amyloliquefaciens CM3 with the ratio of 2:1 had the highest inhibition rate of 59.46%, 13.86% higher than that of single strain Y-48 with the highest inhibition rate of 52.22% among the single strains, 72.65% higher than that of single strain Y-30 and 25.22% higher than that of single CM3, respectively. Pot experiments demonstrated that the control efficacy of this combination on strawberry anthracnose was 68.69%, 23.63% higher than that of chemical agents. Furthermore, this combination effectively promoted the growth of strawberry. The strawberry height, leaf area, fresh weight of root and stem were increased significantly. Taken together, this study provided an experimental basis for the application of complex microbial agent to the biological control of strawberry anthracnose.
