Boxwood blight, a new fungal disease of boxwood to the United States, was identified in Oregon on December of 2011. Boxwood blight has been shown to cause significant defoliation and branch dieback to infected plants and may pose regulation problems with shipping boxwood. In cooperation with the National Plant Board and other departments of agriculture, ODA has initiated the Nursery Cleanliness Program for boxwood blight. This is a voluntary program of inspections and best management procedures designed to help nurseries provide clean boxwood stock to their customers.
