Washington nursery update

Washington has had 10 confirmed positive nurseries to date in 2012, the most in a single year since 2006. Counties with detections include King, Pierce, Thurston, Lewis, Clark, Clallam, and Skagit. Eight of the nurseries are repeat positives and six are certified interstate host shippers, three of which have shipped host and associated host plant material in the past six months. Positive plants have included Rhododendron, Viburnum, Camellia, Magnolia, two Pieris, and one Gaultheria. With most of the positive nurseries in Washington catering to the landscape trade, and the housing industry slow, at least four of the 10 sites have had some of the currently positive plants in the nursery yard for over a year. It is unknown how long they have been infected on site.
