Since 2003, the WSU Puyallup Ornamental Plant Pathology Program has been conducting research on Phytophthora ramorum relating 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 will greatly increase the capacity of WSU to address critical research questions relating 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.
