Revisiting the Realm of Residuals
The ability of glyphosate to be a stand-alone herbicide for weed management in Illinois agronomic crops has been (and will continue) declining, due in large measure to the occurrence of weed species resistant to glyphosate and the presence of species inherently less susceptible to glyphosate. Combining other postemergence herbicides with glyphosate can improve control in some instances, but will not provide a solution in every instance. Soil-residual herbicides, applied before or soon after planting, can improve control of some of the challenging weed management scenarios that plague Illinois farmers. Because utilization of these products is likely to increase in forthcoming seasons, recommendations for optimizing the performance of these products will be discussed.

BIO: Aaron Hager is a native of west-central Illinois where he was raised on a corn and soybean family farm. He attended Southern Illinois University, Carbondale and received a B.S. in Plant and Soil Science in 1991. He then went to Michigan State University and received his M.S. in weed science in May, 1993. Later that month, he joined the University of Illinois as a weed science extension specialist. In 2001, he completed his Ph.D. in weed science and joined the Department of Crop Sciences faculty ranks in 2002. As an associate professor of weed science at the University of Illinois, Aaron is responsible for weed biology and management research in corn and soybean production systems. His research focuses on examining the biology and management of weed species that are becoming increasingly common and problematic in Illinois. Additionally, Dr. Hager has responsibility for the production and annual revision of extension-related publications and coordination for several weed science educational programs in Illinois.
