Interpretive Summary:

Technical Abstract: Research on soilborne pathogens, disease control, and new forest diseases of interest were presented at the Western Forest and Conservation Nursery Association meeting in 2016. Research topics included reduced-rate soil fumigation, Pythium diversity and biocontrol, pathogen movement among nurseries, and a new incense-cedar disease. Results from the fumigation study indicate that reduced rate soil fumigation is effective for soilborne disease and weed control. Results from the biocontrol study provide a partial explanation for why biocontrol may sometimes fail in forest nurseries and results from the population genetics study show that Pythium species are being moved in the forest nursery industry. Our latest forest tree research has shown that there is a new incense-cedar canker disease in Oregon.
