  • Plug mixture for raising seedlings and method for producing it, and method for raising disease tolerant seedlings
    Patent number: 5935571
    Abstract: Herein provided is a plug mixture for raising seedlings, which contains endosymbiotic Pseudomonads mutualistically colonizing in endorhizosphere, Pseudomnonas fluoresceFPT-9601 and Pseudomonas sp. FPH-9601. Using the plug mixture, soil-borne diseases of crop plants and flowering plants can be prevented, and the producibility of such plants can be increased. The plug mixture contains said two Pseudomonads in an amount of not smaller than 10.sup.5 CFU/g each, and may contain 1-?3-(4-hydroxyphenyl)propanoyl!-2-piperidone in an amount of not smaller than 10 ppm. The two strains are separately added to different plug mixtures, which are then blended to give the intended plug mixture for raising seedlings. To this is optionally added 1-?3-(4-hydroxyphenyl)propanoyl!-2-piperidone. The plug mixture is effective for preventing soil-borne diseases, such as bacterial wilt, fusarium wilt and late blight, of various crop plants.
