Sudden oak death – Phytophthora ramorum
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 detected the pathogen on host plants in a number of nurseries in southern coastal British Columbia since 2003.
When P. ramorum is detected, the nursery is placed under quarantine and all infected plant material is destroyed. Trace forward and trace back investigations are conducted to eliminate the organism from the plants for planting pathway.
