The overall goal of the UW Turfgrass Pathology Program is to maintain or advance current levels of disease suppression and turfgrass quality while simultaneously reducing the amount of inputs required for high-quality turf and the non-target effects of those inputs that are used. This goal will not be achieved through one dramatic breakthrough, but through many projects in both basic and applied areas of plant pathology and environmental toxicology that include basic pathogen biology, epidemiology, host-pathogen interactions, cultural practices, and pesticide activity. Cumulative results from projects across the aforementioned spectrum will require collaboration amongst a wide array of researchers, and will eventually lead to high quality turfgrass that require reduced inputs from turf managers. Lab
