DescriptionThe primary purpose of this program was to demonstrate proof of concept of certain mitigation approaches at a repeat P. ramorum-positive nursery site in Washington. Approaches included steam treatment of infested soil areas; creating a gravel “sandwich” above steam-treated and potentially infested soil surfaces; improving drainage systems; required sanitation of pots, flats, and other surfaces; monitoring host plants; and training of staff to identify potential problems and symptoms associated with the life cycle of P. ramorum. Various critical control points (CCPs) were sampled for Phytophthora spp. and the results shared with the nursery and regulatory agencies to demonstrate the effectiveness of their practices. The hypothesis was these specific mitigations will effectively prevent future infestations of nursery stock produced at this site.

- Thermal inactivation of infested plants, nursery equipment, and soil is a management option for the treatment of Phytophthora ramorum, causal agent of sudden oak death
- Survival of Phytophthora species and other pathogens in soilless media components or soil and their eradication with aerated steam
- Relative heat sensitivities of certain Phytophthora spp. and the potential for soil solarization to disinfest nursery beds in West Coast states
