Ginseng replant disease gets the treatment
by Dr. Barry Grace, Acting Director
Getting ginseng to grow in soil where ginseng has grown before is tough business, because fungi and bacteria accumulate in the soil and hinder the growth of new plants. This phenomenon is called ginseng replant disease, and scientists at the Pacific Agri-Food Research Centre in British Columbia have come up with a few solutions to treat it.
Chemical and nonchemical treatment methods were tested, and PARC scientists found useful types for both. Of the chemical methods, Nutri-Q and Busan were the two that significantly reduced seedling mortality rates on replant soil. The two nonchemical methods, Gro-mate Plus and Aldergrove compost, were not quite as effective but still successfully reduced seedling mortality. The results of this experiment provide ginseng growers with a
choice of either chemical or nonchemical treatments to control the problems of ginseng replant disease.
