This volume reports on U.S. Golf Association-sponsored research at 12 universities that examined the degradation and environmental fate of turfgrass chemicals, the evaluation of management strategies for the environmentally sound use of turfgrass chemicals, and the development of alternative pest control strategies using biological and biotechnical approaches. Among the topics of the 26 papers are groundwater contamination potential of pesticides and fertilizers used on golf courses, the effect of salinity on nitrate leaching from tall fescue turfgrass, best management practices to reduce pesticide and nutrient runoff from turf, the use of transgenic plants to confer resistance to brown patch, and microbial strategies for the control of turfgrass diseases.
