Technical Abstract: Soilborne diseases are a serious problem affecting many crop plants of the ornamental nursery industry. Recently, the Horticultural Crops Research Laboratory (USDA-ARS) and Oregon State University received funding from the Floriculture and Nursery Research Initiative via the Horticultural Research Institute to study the interaction of soilborne diseases and environment on nursery plant health. The objectives of our study include: 1) identifying the most common plant pathogens in commercial nursery production systems (including Pythium, Phytophthora, and Verticillium species); 2) developing assays that growers can use to detect the most common plant pathogens; 3) characterize the roles that soil fungi play in nutrient cycling and soil health, and 4) to evaluate methods of disease control. Our research team includes expertise in the nursery industry, soilborne plant pathogens, mycorrhizae, plant physiology, and extension. Together, we hope to improve disease management and soil health for Pacific Northwest nursery production.
