Scott McElroy
PhD, Agronomy and Soils, Auburn University
|
Scott McElroy is an Associate Professor in the Department of Agronomy and Soils at Auburn University. He received his BA in Communication with an emphasis in Chemistry from Auburn University, his MS from the Auburn University in Agronomy and Soils and his PhD from the NC State University in Crop Science with a minor in Plant Ecology.
Dr. McElroy was previously employed as an Assistant Professor and Extension Specialist in Turfgrass and Weed Science at the University of Tennessee in Knoxville, Tennessee. His primary research area at Auburn is on new and improved methods for improved weed management in turfgrass systems, from golf course putting greens to turfgrass sod production to home lawns. Dr. McElroy holds a joint appointment with the Agricultural Experiment Station and the College of Agriculture. He also serves as a reviewer for the Weed Science Society of America Journal, Weed Technology, and the Agronomy and Crop Science Societies of America Journals, Agronomy Journal and Crop Science, and is a member of the American Chemical Society and American Association for the Advancement of Science.
Dr. McElroy teaches two classes, Principles of Weed Science (AGRN 3120) and Applied Weed Science Technology (AGRN 5200/6200). Dr. McElroy is currently developing a third class, Sports Turf Management, for both undergraduate and graduate students.

SUJET DE CONFÉRENCE
|
|
Herbicide chemistry has increased in complexity over the past decade. In North America, there are over fifty individual herbicides registered for use in turfgrass and hundreds of individual products with many different combinations. This seminar will seek to explain herbicide use in terms of those new to the turfgrass market and in context of older, more established herbicide products. In this seminar, we will also discuss the environmental positives and negatives of both new and old herbicide chemistry.

With degrees from Texas Tech University (B.S.) and Texas A&M University (M.S. & PhD.), Dr. Duncan spent from May 1, 1977 to June 30, 2003 at the University of Georgia-Griffin in grass research. His research program was focused on breeding/ genetics/stress physiology of edaphic and abiotic environmental stresses on various grasses and beginning in late 1993 on turfgrasses (tall fescue, seashore paspalum).
His expertise ranged from drought and soil acidity environmental stresses initially to eventually salt/salinity-related problems and turfgrass management involving water conservation strategies, water quality problems, and sustainable alternative water use on all turfgrasses. After retirement from the University of Georgia, he became Vice President of Turfecosystems, LLC. from August 2003 to May 2010 in order to concentrate on developing additional biotic and abiotic stress tolerant turfgrass cultivars, teaching workshops for GCSAA/GIS and international conferences on advanced turfgrass water quality, seashore paspalum management, salt affected turfgrass sites, and turfgrass water conservation.
He currently consults globally, having visited 45 different countries including several countries in the Pacific Rim, on all turfgrass species and water challenges, preparing comprehensive environmentally friendly management packages for site-specific problems, and continues to write books and articles dealing with best management and sustainability challenges on turfgrasses.
He has developed and patented 5 seashore paspalum cultivars and developed 5 stress tolerant tall fescue cultivars that are currently on the market. He is a Fellow in the Crop Science Society of America and the American Society of Agronomy. He has written over 200 refereed scientific publications and has published over 500 total articles.
