Pathology Smorgasbord: Biocontrol, Pathogen Movement, and Recent Fumigation Results

This article summarizes recent research on soilborne pathogens, disease control, and new forest diseas- es including 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 found a new incense-cedar canker disease in Oregon. This paper was presented at the joint annual meeting of the Western Forest and Conservation Nursery Association and the Intermountain Container Seedling Growers’ Association (Troutdale, OR, September 14–15, 2016).
