OverviewAI-generated summary
Jason K. Norsworthy's research focuses on weed science and herbicide resistance in agricultural systems. His work investigates the mechanisms by which weeds develop resistance to herbicides, including non-target-site resistance and the transfer of resistance alleles via pollen-mediated gene flow. He has published on the efficacy of various herbicide classes, such as HPPD-inhibiting and very long chain fatty acid-inhibiting herbicides, and their role in managing herbicide-resistant weeds.
Norsworthy's research extends to the practical application of weed management strategies in specific crops, such as rice, with an emphasis on understanding production practices and associated costs in regions like Arkansas. He also examines the potential impacts of herbicide spray drift on non-target organisms, including pollinators. His scholarly output includes over 510 publications with more than 10,000 citations, and he holds an h-index of 49, designating him as a highly cited researcher. He leads an active research group and collaborates with researchers at the University of Arkansas, including Trenton L. Roberts, Fidel González‐Torralva, Andy Mauromoustakos, and Grant L. Priess.
