ROOT ENDOPHYTE HAVING SOIL DISEASE INHIBITORY ACTIVITY, PROCESS FOR PREPARING SAID ROOT ENDOPHYTE, AND METHOD FOR INHIBITING SOIL DISEASE

摘要

Root endophytes which symbiose within a root of crops were separated andclassified. A medium which cultured the strains were inoculated with a seed ofa crop. The seed was allowed to sprout to inoculate the root of the crop withroot endophytes. While growing the crop, the soil for growth was inoculatedwith soil pathogenic bacteria, and the crop was grown for a period necessaryfor the occurrence of a soil disease. The crop was inspected for pathopoiesis,and root endophytes, which had been inoculated into the root of crop havinglow severity, were specified and selected. As a result, it was found that someroot endophytes can significantly inhibit soil diseases. Among rootendophytes, Heteroconium chaetospira was found to be particularly effective ininhibiting soil diseases.
