Sudden Oak Death (NORS-DUC)

Our mission at National Ornamentals Research Site at Dominican (NORS-DUC) is to provide nursery growers with solutions, and collaborating researchers with lab and field support to aid in their project success in the areas of horticulture and plant disease management.

This project represents an exciting opportunity for the nursery industry in the West, across the country, and beyond. It moves us down the road toward solving tough problems that threaten the sustainability of the nursery industry and will be a model for future collaborative research.

A collaboration between Dominican, the United States Department of Agriculture (USDA) and the California Department of Food and Agriculture(CDFA), NORS-DUC is a research site dedicated to the study of invasive quarantine pathogens of ornamental plants in an open, nursery-like environment.

We invite scientists from other universities, public and private research centers to conduct studies on quarantine soil-borne organisms at our state-of- the-art research facility.

We focus on diseases of ornamental and forest plants, esp. those caused by members of the genus Phytophthora, like P. ramorum, causal agent of Sudden Oak Death and more recently P. tentaculata, a newly discovered plant pathogen in North America impacting native plant nurseries in California.

Our main focus is applied research, such as validation and development of Best Management Practices (BMPs), development of remediation options for soil, water and infested plants, development of monitoring and control strategies. We share the results of our research program with the public through a strong out-reach program, as well as through scientific and technical publications.

NORS-DUC invites DUC students to participate in research activities in the lab and the research nursery.
