I tank mix this with Talstar P (insecticide), and sometimes some 2-4D (clover/broadleaf) - in a 25 gallon ATV sprayer I modified to use on my zero turn/battery powered yard cart. It works quite well.

Also you wouldn't normally mix tenacity with 2-4d as they impact most of the same types of weeks. Including clover
Tenacity is a broad spectrum herbicide that has a slow knockdown taking 14-21 days for full impact.
Tenacity will kill crabgrass at 1-2 tiers, but may require a second application if you're crabgrass is at the 2-3 tier point of maturity
Tenacity will act like a pre-emergant for emerging weeds for 2 weeks. You can re-seed grass before or immediately spraying afterwards with tenacity.
Mixing with triclopyr ester is popular and accelerates the speed of absorption, but additional handling care will be required.
Tenacity has a lower toxicity than most other herbicides, but that goes out the window when you add triclopyr, as that product needs special care when wet or in a vapor format.
I've had no problems killing clover with a single application of tenacity. I can not say the same about creeping charlie, Tenacity harms/stunts creeping charlie, but 2-4d works better for that specific weed. The root network size and scale is likely a factor. I'm spot testing a tenacity+triclopyr mix, which includes creeping charlie. The speed of the action is definitively faster, near x2 speed, but the impact to the creeping charlie does not appear to be as strong as I wanted. I went light on the triclopyr component of the mix at 2oz per gal, which is likely why this mix wasn't as effective. Triclopyr itself is very effective on creeping charlie and is insta-death in regard to being applied to clover.
Tenacity is my go-to broad spectrum twice-a-year herbicide, and has demonstrated minimal impact to the critters living in my year... unlike some of the other alternatives.

I'm presently testing a tenacity+triclopyr mix which includes creeping charlie.... for a limited stop application. 4 gal mix spot treatment over a 20k square foot area. The speed of the action is definitively faster, near x2 speed, but impact to the creeping charlie does not appear to be as strong as I wanted.

If you have a BIG crabgrass problem you need other tools.
The following 2 herbicides are capable of killing most (>90%) 4-5 tier crabgrass in a single application if applied correctly (Northern Lawns):
- Quinclorac (smells horrible, but has the best price/performance ratio) example "Drive XLR8", or Quinclorac 75
- Acclaim Extra Selective (moderate smell, very expensive)
There are mixed herbicides that have some quantity of Quinclorac in them, those do not have the proper mix (qty/ratio) to do what quinclorac applied at the correct rate can do.Both of the herbicides above have application temperature restrictions,
Quinclorac requires methylated seed oil as its surfactant, which is incompatible with tenacity's recommended surfactant, exactly why you don't tank mix the two products.
Weeds can/will build up a resistance to herbicides. So far there have been few signs of any weeds becoming resistant to Tenacity, so yearly or bi-annual applications of tenacity should work for now.
Do not use the 2 more powerful herbicides I listed above often. If your weeds become resistant to them you're effectively screwed. Consider them your tactical crabgrass "Nuclear" option short of a product that kills everything.
The best solution to get rid of crabgrass is NOT to use a herbicide, It's to properly apply pre-emergent. It will take 2 years to resolve 85% of your crabgrass issues with this method but it requires no herbicide. Crabgrass needs to sprout from a seed every season. So if you prevent that weed from sprouting you don't have crabgrass. The only problem is the existing seeds can exist in your soil for several years, but it's the seeds that are either on or near the surface that cause most of the problem.
Simply put, apply pre-emergent correctly and at the right time for 2 years in a row, your lawn will have significantly less weeds. If your neighbor doesn't do this and you are downwind, you will be fighting this battle forever, however as long as you apply pre-emergent (at the correct time) you still will require significantly less herbicides.

There is currently no link to insect impact either. I like having bees too.
