In addition, fungicides are a necessary factor in maintaining the availability of fiber and landscape improvements ranging from forest management to enhancements through the use of ornamentals. Agricultural fungicides are a significant component in effective disease control and are critical to plant health management systems. Fungicides provide benefits to producers as well as consumers and to local as well as national economies. Farmers benefit from the prevention of yield losses, improved crop quality, enhanced market opportunities, facilitation of farmwork and harvest. Consumers also benefit from an ample, varied, safe, healthy and inexpensive food supply that is available throughout the year. This is one of 11 separate reports that assessed the beneficial aspects of fungicide use in U.S. agriculture. The 11 reports, all using a commodity approach in evaluating fungicide use, comprise the Fungicide Benefits Assessment. This assessment represents one part of the USDA/States National Agricultural Pesticide Impact Assessment Program's Fungicide Assessment Project. The two other parts deal with (a.) a treatise examining the health and environmental factors associated with the agricultural use of fungicides, and (b.) an assessment of the status as well as the management strategies for fungal resistance to fungicides in the U.S. The 11 Fungicide Benefits Assessment reports were prepared by a team of scientists (team leaders). The team leaders and the listing of their reports (by commodity) in the Fungicide Benefits Assessment are as follows: Team Leader Commodity POUTIMAY OLS ieests epee tereie 20 a tavedels =, Turf Department of Plant Pathology 211 Buckhout Laboratory The Pennsylvania State University University Park, PA 16802 GAGVEDELE SLT OMini amie. sitelsisl=seeltvsn s Field Crops - North Department of Plant Pathology 317 Plant Science Building Cornell University Tthaea, NY 14853 MichaeVeDAV LS. ptcustiitoslo eieere one Vegetables - West Department of Plant Pathology University of California Davis, CA 95616 Douglas Gubler...............- Fruits & Nuts - West Department of Plant Pathology University of California Davis, CA 95616 Kenneth Hickey.............0- Fruits & Nuts - East Fruit Research Lab Box 309 290 University Drive The Pennsylvania State University Biglerville, PA 17307 Stephen Johnston..............
