Root endophytes which symbiose within a root of crops were separated and classified. A medium which cultured the strains were inoculated with a seed of a crop. The seed was allowed to sprout to inoculate the root of the crop with root endophytes. While growing the crop, the soil for growth was inoculated with soil pathogenic bacteria, and the crop was grown for a period necessary for the occurrence of a soil disease. The crop was inspected for pathopoiesis, and root endophytes, which had been inoculated into the root of crop having low severity, were specified and selected. As a result, it was found that some root endophytes can significantly inhibit soil diseases. Among root endophytes, Heteroconium chaetospira was found to be particularly effective in inhibiting soil diseases.
On a séparé et on a classé des endophytes de racine vivant en symbiose avec une racine de culture. On a inoculé une graine de culture dans un milieu de culture de souches. On a laissé germer la graine pour inoculer les endophytes de racine à la racine de la culture. Lors de la croissance de la culture, on a inoculé le sol de croissance de bactéries pathogènes du sol, et on a laissé pousser la culture le temps nécessaire pour qu'apparaisse une maladie du sol. On a inspecté la culture dans le cadre d'une pathopoïèse et on a spécifié et sélectionné les endophytes de racine qui avaient été inoculés dans la racine de la culture encore peu atteinte. Résultat, on a découvert que certains endophytes de racine peuvent inhiber sensiblement des maladies du sol. Parmi les endophytes de racine, on a découvert que Heteroconium chaetospira est particulièrement efficace dans l'inhibition des maladies du sol.
