This study deals with the relation of distribution of the pathogen causing rhizome rot disease of ginger in soils adjacent to plastic houses to the disease outbreak in continuous indoor cropping for immature rhizome production. At least three species of Pythium were found in soils adjacent to plastic houses. Pythium zingiberum, which is less abundant than the other species, was found to be pathogenic to the young ginger plants. No definite role of the pathogen for primary infection was found although the fungus was detected in soils adjacent to the house with history of rhizome rot disease. The population of pathogen decreased rapidly in dumping place for ginger refuse. The pathogen in sufficient inoculum potentials for disease outbreak was detected most often along the drainage canal where ginger rhizomes were washed.
