WSU Sudden Oak Death Research

WSU Research Facility

Since 2003, the WSU Puyallup Ornamental Plant Pathology Program has conducted research on Phytophthora ramorum related to host range, epidemiology, and evaluating potential control options.

In response to industry concerns, WSU built a quarter-million-dollar biocontainment facility at Puyallup. This facility has increased the capacity of WSU to address critical research questions related to the establishment, host susceptibility, spread and management of P. ramorum. A molecular lab has also been established to enhance research relating to the detection, spread, and genetics of this pathogen.

Research

Phytophthora ramorum poses substantial challenges to industries and land managers in the Western United States, including Washington State. Therefore, much of our research is dedicated to providing guidance and solutions in terms of risk assessment and management.

Below we provide information about our research in four broad categories. Click on the images or links below to find more information about the research we have conducted in each category.
