Pathogenic bacteria remain in the soil mycelium, bacteria or sclerotia overwintering, the next year in the environment when the germination of suitable germination caused new infections. A chronic disease, the incidence of death from the plant, generally take more than 3 years. Multi-use soil disinfectant for processing, the current reader to introduce the Japanese agricultural research institute of a research results, the use of sawdust on white feather disease non-pathogenic bacteria culture, to achieve effective control of white feather disease.
