The Boxwood Blight Cleanliness Program utilizes a systems approach to prevent the spread of boxwood blight via nursery stock.

The Boxwood Blight Cleanliness Program is a voluntary program. Participating nurseries agree to use best management practices, developed by the National Plant Board and nursery industry, to reduce the risk of introducing and spreading boxwood blight, which is caused by the fungus Calonectria pseudonaviculata (also known as Cylindrocladium pseudonaviculatum and Cylindrocladium buxicola). The program is coupled with inspections and audits by the Office of Plant Industry Services.


Training for Growers

The Boxwood Blight Cleanliness Program requires continuing education on this disease for participating nurseries. Below are some online resources on the management and biology of this pathogen to help meet this requirement.
