Description: Annual national surveys for Phytophthora ramorum have been conducted in Canada since 2002. Over 37,361 samples were taken in 2006, which focused on 251 wholesale and retail nurseries across Canada that were either growers or importers of host plants. In 2006, the national survey detected P. ramorum at one wholesale and four retail nurseries in the province of British Columbia. To-date in Canada, there has only been regulatory incidents of P. ramorum at nursery businesses, restricted to areas of the Lower Mainland, Vancouver Island and Sunshine Coast of British Columbia. Trade in nursery plants with currently known infested states is thought to be the source of inoculum for these nurseries. The Confirmed Nursery Protocol or Enhanced Confirmed Nursery Protocol has been implemented to eradicate P. ramorum at these sites.
