Sudden Oak Death: A New Disease in Oregon(3:45-5:15 p.m.)
Sudden Oak Death, an introduced disease, is causing extensive damage to oaks in California. The disease was recently reported in Curry County. The fungal disease, related to the organism that caused Ireland’s potato famine, causes Port-Orford-cedar root rot in southern Oregon and northern California. Sudden Oak Death causes mortality in black oak, live oaks, and tanoak, and a leaf and twig dieback of laurel, bigleaf maple, manzanita, rhododendron, and vaccinium. It has not been reported on Oregon white oak, but it has been found on redwood and Douglas-fir foliage in California. This class will discuss the basic biology of the disease and ramifications should the disease be found on Douglas-fir or white oak in Oregon.
