Interest in canola as a rotation crop in the cereal-dominated cropping systems of the Pacific Northwest continues to increase, particularly with depressed wheat prices, and with steady demand from the Pacific Coast Canola processing facility in Warden, Wash. The Crucifer Quarantine enacted last fall, however, has prompted many questions and requests for advice about blackleg from growers and industry. In response to concerns, faculty at the Washington State University-based Washington Oilseed Cropping Systems Project developed a handout to distribute at field tours. The guide includes concise information about the current status of blackleg in Washington, the Crucifer Quarantine requirements, scouting for blackleg, and photos of blackleg symptoms from fields in Idaho and Oregon.
