2024 Abstract - WHAT'S LEFT AND WORKING FOR SOYBEAN WEED CONTROL?: Herbicide resistance is consistently increasing in numerous weed species across Arkansas, particularly in Palmer amaranth where chemical options are beginning to dwindle. Additionally, weeds like common cocklebur, sicklepod, and prickly sida (teaweed) are making a comeback, and Italian ryegrass and sedge species are quickly becoming severely problematic across the state further complicating our weed control efforts. This talk will explore current herbicide resistance concerns and distribution, current control strategies that have been effective both in research and commercially, and future control efforts to consider.
