    Abstract: A biocontrol strain YW-1, a preparation method and application of a biocontrol agent thereof are provided. The strain is Myroides odoratimimus with the preservation number of CGMCC NO. 20620. The biocontrol agent of the biocontrol strain YW-1 is obtained by the following steps: oscillating culture the biocontrol strain YW-1 in a LB culture medium at 30 Celsius degrees and 180 rpm for 12-16 hours until a total concentration of living bacteria in a bacterial suspension is 1×109-1×1010 CFU/mL; centrifuging the bacterial suspension at 6000 rpm for 10 minutes to collect bacterial cells; and diluting the bacterial cells with sterilized water to obtain a concentration of 100 CFU/milliliter. By irrigating the root of every plant with 20 milliliters of the biocontrol agent when host plants are transplanted, it can effectively prevent soil-borne diseases such as fusarium wilt of melons, bacterial wilt of tomatoes and peppers, and Phytophthora capsici.
