This presentation begins by reviewing cotton crop conditions for 2022 and abandonment rates for 2018–2022. The discussion then turns to traditional weed management challenges and additional challenges for 2023 and beyond, including herbicide availability and increased costs, widespread development of herbicide-resistant weeds, and increased label restrictions. Both traditional and additional best practices for weed management also are covered, plus common themes for success.
