All bentgrass is dormant now. Wisconsin climate. Looking to apply late summer/early fall.
Your first application of Tenacity Herbicide in the fall to control bentgrass will be most effective just before the onset of new growth. You can then apply at 2-3 week intervals. You do not want to wait for it to be fully re-established to start treatment.
