Abstract
Effect of combined application of an antagonist and natural antifun-gal materials which are safe for soil environment and human health was examined for the control of root rot of ginseng. The root rot of ginseng is one of the most frequently occurring diseases in ginseng fields. Various factors such as pathogens especially Cylindrocarpon destructans and pre-existing or infested microorganisms affect the development of ginseng root rot. The resistance of the pathogen to the wide variety of chemicals has stimulated the search of new alternatives for control measures. Use of plants extract is one of the most promising, effective, safer and ecofriendly method to eradicate the pathogens from soil. This study was designed to evaluate the efficacy of six plants extracts viz., Eugenia caryophyllata (Dried Clove Buds, DCB), Coptis chinensis (Coptis), Cinnamomum cassia (Cassiae Cortex, CC), Cnidium officinale (Cnidii Rhizoma, CR), Paeonia suffructicosa (Moutan Cortex Radicis, MCR), Phellodendron amurense (Phellodendri Cor-tex, PC) in the control of C. destructans CY9801. Ethanol extraction, each of stem bark of CC and flower bud DCB showed a strong antifungal activity against C. destructans CY9801. Furthermore, mycelial growth of C. destruc-tans CY9801 was inhibited by CC and DCB. The rot symptom reduction rate varied depending on the extraction inoculum density. Among them, 10% extracts of both CC and DCB exhibited the best antifungal activity, whereas an adverse effect on ginseng surface was accompanied at the high concentration of CC. Our results suggest that extracts of Eugenia caryophyllata and Cinnamomum cassia have an antifungal effect against C. destructans and seem to be effective for biological control of ginseng root rot disease as an alternative to conventional chemical fungicide.
