Biography and Research Information
OverviewAI-generated summary
Jason K. Norsworthy is a Professor in the Department of Crop, Soil and Environmental Sciences at the University of Arkansas at Fayetteville. His research program focuses on weed science, with an emphasis on herbicide resistance in agricultural systems.
Norsworthy's work investigates the mechanisms of herbicide resistance in various weed species, including Palmer amaranth (*Amaranthus palmeri*) and barnyardgrass (*Echinochloa crus-galli*). He has published research on the efficacy of different herbicide classes, such as HPPD-inhibiting and very long chain fatty acid-inhibiting herbicides, and their role in weed management. His studies also explore the genetic transfer of resistance alleles through pollen-mediated gene flow. Additionally, Norsworthy has examined the implications of herbicide spray drift on non-target organisms, such as pollinators.
With a publication record of over 488 articles and an h-index of 50, Norsworthy is recognized as a highly cited researcher. He collaborates with several colleagues at the University of Arkansas, including L. Tom Barber, Trenton L. Roberts, Fidel González‐Torralva, and Andy Mauromoustakos. His research group actively maintains a lab website detailing their ongoing projects.
