Karen Bailey

Karen Bailey is a retired research scientist who specialized in plant pathology and biopesticide development at Agriculture and Agri-Food Canada. Her research focused on developing alternatives to synthetic pesticides and improving plant health through integrated pest management strategies. She is internationally recognized for her expertise on soil-borne pathogens and biological control, and she has more than 250 publications, 23 patents, and 7 inventions disclosures in progress. She joined Agriculture and Agri-Food Canada as a biologist, and later as a research scientist after obtaining her Ph.D. in Plant Pathology and Plant Breeding from the University of Saskatchewan. The indigenous fungus Phoma macrostoma was formulated to control weeds such as dandelion, clover, wild mustard, and ragweed, without harming crops and grasses. It can be applied as a granule to soil before the weeds emerge, which prevents establishment for 1–3 months, or applied post-emergence, which causes affected weeds to turn white and die due to a lack of chlorophyll.

Bailey has also been involved in numerous scientific projects in the U.S., Syria, Morocco, Tunisia, Egypt, Australia, New Zealand, Russia, India, Switzerland, and Belgium. She has been a member of the Editorial Boards for the journals Weed Research, Agriculture, Ecosystems, and the Environment, and Canadian Journal of Plant Science.

Honours and awards

Bailey received the Canadian Phytopathological Society (CPS) Award for Achievements in Plant Disease Management, the CPS Award for Outstanding Research, and the Queen’s Diamond Jubilee Medal for her contributions to Canadian Agriculture. She was President of the Canadian Phytopathological Society.
