Effect of Solarization and Soil Fumigation after Green Manure Incorporation on Reduction of Replant Failure in 4-Years-Old Ginseng

Ginseng root rot, caused by Ilyonectria radicicola (Cylindrocarpon destructans) and Fusarium solani is a major cause of replant failure in continuous cropping ginseng. Accordingly, various methods have been attempted to reduction of replant failure in ginseng. Solarization is an eco-friendly and economical soil sterilization method that sterilizes soil-borne pathogens by raising the temperature using solar heat in summer. Soil fumigation is a chemical method of disinfecting soil using fumigants, such as dazomet, and is the most effective. In this study, we investigate effect of solarization and soil fumigation on reduction of replant failure in ginseng.
