  • USDA Revises Quarantine Regulations for P. ramorum

    The United States Department of Agriculture, Animal and Plant Health Inspection Service, USDA-APHIS, has revised the Phytophthora ramorum quarantine for nurseries in regulated areas.  The previous rule required nurseries in Oregon, Washington, and California to provide official annual inspection/ host sampling as well as pre-notification to regulatory officials in recieving states. Under the revised rule, only nurseries that have been found positive for P. ramorum within the past three years (on or after March 31, 2011) will be required to comply with quarantine regulations. Regulations remain the same for nurseries in quarantine areas. Please feel free to contact the ODA if you have questions concerning the revised rule. For more information, please visit USDA's P. ramorum website.

  • Nursery Cleanliness Program for Boxwood Blight


    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. For additional information, please contact the ODA, Plant Division, Nursery Inspection Program.
