No, Tenacity Herbicide is not labeled for Horse's Tail (Equisetum arvense), so we would not recommend using this product for it.
It may be fine to mix both Tenacity and Gordon's Trimec together but has not been tested by the manufacturer. We recommend that you perform a jar test to an inconspicuous area first prior to a full application to confirm if you wish to use them both together.

There are no restrictions on the label for Tenacity Herbicide regarding timing around application of beneficial nematodes. Unfortuunately, not too much is known about the possible effects of using herbicides when applying beneficial insects. We would not recommend mixing or applying Tenacity immediately after appying the nematodes. We recommend contacting the manufacturer of the nematodes you are using for their recommendation on how long to wait between these applications and which is best done first.
Tenacity Herbicide is only labeled to suppress Poa Annua as pre-emergent. Tenacity Herbicide DOES NOT have any post emergent control when the poa is actively growing.

We would not suggest mixing Tenacity and a glyphosate product as there would not be much benefit in doing so. You could mix a pre-emergent like Dimension 2EW or Prodiamine 65 which would cover many broadleaf and grassy weeds.
When Tenacity Herbicide is used for post-emergent control of weeds the weeds are sprayed directly. According to the product label, when used postemergence, susceptible weeds absorb Tenacity through foliar contact and soil absorption. The foliage of treated weeds cease growth after application, then turn white (loss of chlorophyll) and death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control.
Tenacity Herbicide should not be used if the seed you are putting down is more than 20% fine fescue. If you have a fescue blend that is less than 20% fine fescue, then it should be safe to use Tenacity before or at the same time as seeding. Please refer to the product label for full application instructions.
