Frank S. Rossi, Ph.D., of Cornell University, will review the latest research published in 2009-10 that will be helpful in developing a fertility program focused on cost effeciency, plant health and environmental compatibility. He also will review soil and tissue testing, fertilizer source and timing selection for sand-based and native soil areas, as well as nutritional supplements that might enhance stress tolerance.

Lane Tredway, Ph.D., of North Carolina State University will discuss some of the new turfgrass fungicides available for use by golf course superintendents and how to use them. His presentation will include how to select the most effective fungicide treatments and how to integrate new fungicide chemistries into existing disease-control programs, maximize effectiveness through weather-based timing of applications and proper-use techniques, control new and emerging diseases in golf course turf, and develop effective and cost-efficient programs designed to prevent onset of fungicide resistance.
