SOD Pest Risk Assesment

from canadanursery.com

"...Tree mortality of both live and tan oak has been confined to the coastal fog belt and in association with bay laurel. ...
P. ramorum is considered to be a nursery disease and while many plant species can be infested with P. ramorum, only a few are capable of spreading the disease. These include Rhododendron, Camillia, Kalmia, Viburnum and Pieris. ...

CFIA have proposed regulating only the five high-risk host plants at the genus level with all other plants will be regulated at the species level, in harmony with USDA regulations. Changes have also been made to the P. ramorum infested nursery protocol to reflect the lower risk status of the disease. Industry is invited to comment on both; they can be downloaded from the CNLA website"
