Responses of Soil Bacteria Communities to Organic Material Application and Their Antagonistic Activity against Diaporthe destruens Causing Sweet Potato Foot Rot Disease.

ABSTRACT: Sweet potato foot rot disease caused by Diaporthe destruens (formerly Plenodomus destruens) severely affects the yield and quality of sweet potatoes. To gain basic knowledge on regulating the pathogen using indigenous soil bacteria, the following organic materials were applied to potted soils collected from a sweet potato field contaminated with D. destruens: Kuroihitomi (compost made from shochu waste and chicken manure), Soil-fine (material made by adsorbing shochu waste on rice bran), and rice bran. Soil samples were periodically collected during an incubation for bacterial colony counts and a community ana-lysis using a meta 16S amplicon ana-lysis. The number of bacterial colonies was significantly higher with the Soil-fine and rice bran treatments and slightly higher with the Kuroihit
