Tenacity Herbicide will suppress Bentgrass after a few applications but is not labeled to suppress bermuda. Please follow the product label for application. Be sure to apply during cooler times of the day to avoid harming your desired turf grass.
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.
Tenacity Herbicide can be used when the clover or other weeds are actively growing. It also can be applied when seeding with some grass types. You can check with your local cooperative extension office Master Gardener for specific timing in your area.
You can use Tenacity Herbicide at the same time as a fertilizer either as a pre or a post emergent provided you use both at the correct usage rates per the labels.
Per the label for Tenacity Herbicide, it is best to treat nimblewill with 2-3 applications which are 2-3 weeks apart. If the nimblewill is still green, then you can go ahead and retreat now. If it is already dormant, then it would be best to wait until it is green again to treat with herbicides.

The label for Poa Constrictor does not mention anything about tank mixing with another herbicide such as Tenacity Herbicide. Per the Tenacity label: Other tank mixture partners may be safe but have not been tested. Turf managers wanting to tank mix Tenacity with other herbicides should test on a small basis for compatibility, safety and efficacy before treating large areas.
We would recommend doing a compatibility test before treating.
Your timing is really going to depend on a lot of factors, such as the weeds you are targeting and if/when you are seeding. We would exercise caution if you are applying multiple herbicides at the same time, especially since Trimec is already a blend of 3 active ingredients. Mixing Trimec and Tenacity would be used only as a spot spray, and we would still do a small jar test before mixing a tank of these as well as testing an inconspicuous area of the lawn for tolerance first. You should only use Tenacity as a broadcast pre-emergent application if you are renovating or overseeding the lawn, and most Trimec products require you to wait 2-4 weeks after application before you can reseed. Please let us know if you have additional questions about your application.
Tenacity Herbicide should not be sprayed on edible crops, including almond trees. The product should be applied outside of the dripline of the trees, and take special care not to allow any overspray or drift to contact the tree.
Tenacity Herbicide is only labeled for use on turfgrasses. It could harm ornamental grasses if applied over them.
