Washington State Emergency Rule

WAC 16-470-750  Establishing quarantine for Phytophthora ramorum.  Phytophthora ramorum is a non-native, invasive fungal-like pathogen that causes sudden oak death disease in some oak species and severe canker, blight or twig dieback in numerous other plant genera. The pathogen is capable of spreading through multiple pathways, including infected host species in nursery stock.   Known infestations have occurred in Washington in a few sites, all of which have been contained.  Known infestations have recently been found in nursery stock shipped into Washington and many other states from at least one major producer in California.  If allowed to become widely established in Washington, Phytophthora ramorum could have a devastating economic impact on the agriculture and forestry industries of the state and could endanger the environmental quality, native plant populations, and natural resources of the state.  The director of agriculture, pursuant to chapters 17.24 RCW and 15.13 RCW, has determined that the regulation and exclusion of host species, associated soil and potting mix, and cultures of Phytophthora ramorum itself, is necessary to protect the agricultural crops, economic health and environmental quality of the state.
