METHOD FOR CONTROLLING PLANT DISEASE DAMAGE USING SYMBIOTIC MICROORGANISM AND NEW MICROORGANISM USED IN PRACTICE OF THE METHOD

摘要

PURPOSE:To control a pathogenic fungus by antagonism by proliferation of a microorganism and provide resistance to disease damage to a germ-free culture seedling by separating the microorganism symbiosed in a disease-free tissue of a plant and inoculating a seedling having affinity with the microorganism with the microorganism. CONSTITUTION:A microorganism symbiosed in a disease-free tissue of a plant is separated and the separated and cultured microorganism is inoculated into an ordinary culture seedling or germ-free culture seedling capable of exhibiting affinity with the microorganism. As a result, a pathogenic fungus is controlled by antagonism by proliferation of the microorganism. The above-mentioned microorganism includes e.g. Pseudomonas CP-098 (FERM-11629) providing resistance to disease of cyclamen.
