Annual ryegrass is rapidly becoming one of the toughest weeds in U.S. row‑crop agriculture. In this episode, Alyssa Essman (Ohio State) and Joe Ikley (NDSU) talk with Tom Barber (University of Arkansas), Charlie Cahoon (NC State), and Larry Steckel (University of Tennessee) about how this weed is spreading, shifting its emergence timing, and developing resistance to multiple herbicide groups. The guests discuss the strengths and weaknesses of current control options, the importance of fall residuals, and how tactics like tillage, cover crops, and harvest weed‑seed control fit into an integrated approach. They also share ongoing research aimed at better understanding ryegrass biology and improving long‑term management.   https://crop-soil-environmental-sciences.uark.edu/people/faculty-directory/uid/ltbarber/name/Tom+Barber/ <a href= "https://crop-soil-environmental-sciences.uark.edu/people/faculty-directory/uid/ltbarber/name/Tom+Barber/"> [crop-soil-...s.uark.edu]</a> https://cals.ncsu.edu/crop-and-soil-sciences/people/cwcahoon/ <a href= "https://cals.ncsu.edu/crop-and-soil-sciences/people/cwcahoon/">[cals.ncsu.edu]</a> https://utcrops.com/field-crops-team/ <a href= "https://utcrops.com/field-crops-team/">[utcrops.com]</a>
