Quackgrass is not on the label to be controlled by the Tenacity, and we cannot recommend you use it for your needs with it not being listed. We do however carry Certainty, which is a selective post emergent herbicide like Tenacity, and does have Quackgrass listed on the label for weeds controlled. You can see the dilutions and what grasses Certainty is safe to be used on, on the product label.
According to the Tenacity product label you can apply prior to seeding or post seeding of tolerant turfgrass species listed on the label, except fine fescue. If you are applying Tenacity after seeding, you should wait at least four weeks or two mowings, whichever is longer, before applying Tenacity.
Tenacity Herbicide is not labeled for post emergent control of burweed.
Tenacity Herbicide is only safe to use on dormant Bermudagrass, and it will not offer post-emergent control of poa annua, per the product label. A better choice to control existing poa annua in bermudagrass would be Monument 75WG Herbicide. Be sure to use a non-ionic surfactant with Monument as well. We also recommend using a pre-emergent herbicide such as Dimension 2EW or Prodiamine 65 WDG in late Summer/early Fall for the best control of annual bluegrass. Please see our Poa Annua Lawn Care Guide for more tips and information.

Tenacity Herbicide is labeled to be safely applied to fine fescue and is not labeled to kill it so we cannot recommend it for that use. When you are trying to remove another cool season turf type from KGB the best option is to use a product like Roundup Quikpro (or non selective/glyphosate) and then re-seed with your KBG.

Tenacity is only going to suppress poa annua when used as a pre-emergent for it. You would really only use Tenacity as a pre-emergent over the entire lawn if you are needing a pre-emergent to use at the same time as seeding or over-seeding. Otherwise, ProGrass would be a better choice for poa annua control and for use on established perennial ryegrass.

Tenacity Herbicide is our most popular product for eliminating bentgrass from other desirable turfgrasses, but it does typically require multiple applications. Late summer/fall applications will be more effective than spring applications. If you are able to spot treat with RoundUp QuikPro, that is another option. It would still be ideal to wait at least 10-14 days after applying the Roundup QuikPro before raking out the dead plants and re-seeding those areas.
