AbstractWorld-wide, Phytophthora ramorum has emerged as a quarantine-pathogen of significance, spurring emergency regulatory actions to address the spread of P. ramorum within ornamental nurseries and from infested nursery stock to native wildlands. After four years of collaborative efforts between California Department of Food and Agriculture, U.S. nursery industry, California Oak Mortality Task Force, National Plant Board and USDA, a site to perform research on P. ramorum under natural conditions was located in California. Funding via the U.S. Farm Bill (Section 10201) was secured and administered by the Center for Plant Health Science and Technology to develop the National Ornamentals Research Site at Dominican University of California (NORS-DUC). Situated in P. ramorum-quarantined Marin County, California, NORS-DUC was developed with safeguards to contain the pathogen and prevent spread to the environment. NORS-DUC has provided an unparalleled opportunity for researchers that are now conducting field studies to address the treatment of and prevention of P. ramorum in soil, the risk of asymptomatic infection in fungicide-treated plants, the effect of fungicides on inoculum production, biological control agents, and the affects of abiotic stress and ramorum blight in nursery ornamentals. While the current research at NORS-DUC focuses on P. ramorum, and will benefit the nursery and forestry industries, the data gathered will be applicable to the management of other pathogens.
