With six options to fit your soil types, tillage practices, and weed management needs, Authority brand herbicides have the pre-emergence power to fight glyphosate-resistant weeds before they even take root. Apply as part of a pre-plant strategy in the spring or fall burndown for strong residual control and reliable results.
