Development of mangement strategies for replant disease in ginseng production in Ontario
Project Code PRR14-050

To generate knowledge on the replant disease complex and develop management options to improve ginseng re-cropping opportunities for old gardens
Finding effective and sustainable management options to address replant disease is a priority issue for ginseng producers. In Ontario, where the majority of the Canadian ginseng is cultivated, most of the fields are only cropped once to ginseng because of the high level of infestation with soil borne pests in old gardens posing a serious threat to new ginseng crops.
A need was identified to study the etiology of ginseng replant disease complex for developing scientifically and economically sound management approaches to reclaim old garden fields for ginseng re-cropping. This project aims to generate new knowledge on the pathogen complex associated with replant disease in ginseng, identify the role of ginsenosides in this pathosystem, and investigate sustainable management approaches, including biofumigants, biopesticides, biological and cultural practices to address this pest issue. The research work includes laboratory, greenhouse and screenhouse efficacy trials to identify promising management practices to be then validated in the field scale. The goal is to develop various tools and practices to allow for an integrated management system for replant disease in ginseng production.
