Phytophthora ramorum, is a fungus-like plant pathogen that causes a disease known as Ramorum Blight and Leafdrop on a wide variety of nursery plants. It has also been associated with a disease of oak, known as "Sudden Oak Death" that was first observed in coastal California in the mid-1990's and now occurs as far north as southern Oregon.
The Canadian Food Inspection Agency conducts annual surveys for P. ramorum and has in the past detected the presence of the organism on plants in a number of retail/wholesale nurseries (mainly associated with imports from the United States) in the southern coastal area of British Columbia. When P. ramorum is found, the nursery site is placed under quarantine and all infected plant material is destroyed. Extensive surveys and traceforward and traceback activities are then conducted to ensure the organism has been eliminated.
