Abstract

Abstract: In this paper,two fungi FC2016-3 and FC2016-7 were successfully isolated from the diseased root of strawberry,and identified as Fusarium oxysporum. Bacillus amyloliquefacien CM3 presented obvious inhibitory effect on FC2016-3 and FC2016-7,and also had a promising inhibitory effect on other soil borne pathogens. The results of pot experiment showed that the control effect of strain CM3 on strawberry root rot caused by F. oxysporum FC2016-7 was up to 64.86%,and strain CM3 also demonstrated the ability of promoting root growth of strawberry. This study reveals that strain CM3 is a strain that can prevent soil borne disease and simultaneously promote plant growth,therefore,it is appropriate for the development of microbial preparation.

Key words: Fusarium oxysporum, Bacillus amyloliquefacien, biological control
