Sudden Oak Death — Phytophthora ramorum
The plant pathogen, Phytophthora ramorum, which causes the disease known as Sudden Oak Death (SOD), was recently discovered on horticultural nursery stock in Oregon, Washington, and British Columbia. The name of the disease is somewhat misleading, as the pathogen attacks many plants other than oaks. The current host list contains plants from many plant families (i.e. Douglas-fir, rhododendron, vaccinium, madrone, pieris, virburnum, and camellia) that are extremely important to the ornamental, small fruit, Christmas tree, and forest industries in Washington State. If this pathogen becomes established in Washington, resulting quarantines relating to the movement of hosts of this pathogen from quarantined areas have the potential to impact individuals and companies who sell their products locally as well as those who export them out of state or to other countries.
In order to help bring professionals up-to-speed on this disease, a cadre of university, state and federal agency personnel developed a one-day informational conference on SOD. The conference was held on July 9th, at the WSU-Puyallup Research and Extension Center. The invited speakers provided information on several key issues: SOD Overview; current SOD surveys in Washington State; PNW SOD Research; SOD Regulatory Issues; and Industry Perspectives.
Since space was limited and only 132 people were able to attend this conference, each of the presentations was video taped and is available for viewing. In addition to increasing the dissemination of the information presented at this conference, it is our hope that these video presentations will stimulate a continuing dialogue between all interested parties.
