PROBLEM TO BE SOLVED: To provide a soil infectious disease control method with the growth acceleration of a crop plant, and a method of providing useful microorganisms, a soil pH correction substance or a plant disease resistant inducer referred to a soil infectious disease control method with the growth acceleration of a crop plant.SOLUTION: In a soil infectious disease control method, in the dissemination-seedling period of a crop plant, by the investment of useful microorganisms and a plant disease resistant inducer to a culture soil or crop plant and by the investment of a soil pH correction substance to a culture soil, after the field planting of the crop plant, the synergistic pathopoiesis suppression effect of the useful microorganisms, the soil pH correction substance and the plant disease resistant inducer or crop plant growth promotion effect produced therewith are derived. In a method of detecting the useful microorganisms, the soil pH correction substance or the plant disease resistant inducer, at the dissemination-planting period of the crop plant cultured so as to infect soil habitat plant pathogenic bacteria, the microorganisms, acidic or alkaline substance or material to be a candidate is sampled, and whether it is useful for a soil infectious disease control method with the growth acceleration of a crop plant is decided.
