Greg from Green Bay, Wi writes

To kill extensive bentgrass, is it best to apply the first application of Tenacity as soon as the grass begins to come back or wait until the grass is completely back and fully green?

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.
