Abstract
Penicillium spp. were predominant among 28 fungus genera recovered from the roots of the strawberry plants grown in the potted pasteurized soil set in the field, whereas Rhizoctonia and Fusarium spp. dominant among 30 genera from the roots in the potted natural soil. Increased growth of the plants in the former soil as compared with the growth in the latter about 130 days after transplanting may be attributable to the reduction of the root damage due to potential soilborne pathogens including Rhizoctonia solani by the antagonism of Penicillium spp.
