Tenacity Herbicide is labeled to control bentgrass but it does need to be applied when it is actively growing and healthy. Per the product label: Apply Tenacity at 5 fl. oz. per acre in at least 30 gallons of water per acre at two to three week interval for up to three applications. Apply with a NIS surfactant. Bentgrass control may be more effective in the late summer/early fall just prior to onset of renewed bentgrass growth, than spring/early summer applications
