Kansas State University's 2024 Chemical Weed Guide brings essential updates for effective crop management. Sarah Lancaster, a K-State weed specialist, details significant changes influencing chemical weed control practices in Kansas.
One significant change revolves around atrazine-containing herbicides and their 24(c) labels. Lancaster highlights restrictions on atrazine use for row crop stubble, altering the traditional fall applications on milo or corn stubble.
Notably, atrazine usage on wheat stubble remains unaffected despite ongoing environmental scrutiny.
Newly introduced herbicides like Kyro, intended for postemergence corn application, differ from Resicore due to their active ingredient variations.
Store, a novel herbicide similar to Acuron but enriched with pyroxasulfone, contains potent ingredients addressing herbicide resistance.
The absence of atrazine in premixes aligns with ongoing discussions about its environmental implications, allowing farmers to adjust rates for individual field requirements.
Tarzac, a winter-released wheat herbicide, tackles marestail and problematic bromes like cheatgrass and Japanese brome.
Updates also extend to cotton herbicide strategies, introducing Zidual impregnated on dry fertilizer as a solution.
Minor adjustments include rebranding imazamox products as Beyond Xtra and stable herbicide prices.
The 2024 Chemical Weed Guide is available online, with print copies accessible post-January from K-State Research and Extension. Distribution will occur through various winter programs and extension educators across Kansas.
