GETTING RID OF THE WEEDS FINALLY!
By Dwayne on 10/16/2020
After much research and reading reviews I finally decided to try the more professional product( tenacity) instead of the big box store products. All I can say is I wish I would have used it sooner instead of wasting time and money with the other products. After two weeks crab grass and other weeds are just about completely dead. I was aware of the white appearance once the product began to kill the weeds but I didn't realize until then that I had more weeds than I was seeing initially. I have made two applications and loving the results so far. This is definitely my go to weed control product from now on.

IT WORKS!
By Aj on 10/30/2020
Heard about this product on YouTube. We bought a neglected 4-acre property, and in the past 4 years, we had tried every product that we knew about, and never saw the results we wanted. Until, Tenacity herbicide!! This stuff is great and does what it says it will do. A little goes a long way, so don't be put off by the price for a "little bottle." It is super-concentrated. Because our property was so neglected for years, we simply repeated applications approximately every 6 weeks or so. And it WILL kill everything, so be careful around any trees/shrubs/flowers. Great stuff!

Best yet.
By Mike on 04/04/2022
I struggled recently with growing weeds taking over my front lawn. Living in South Carolina, deer walk thru our yards at night and leave dropping containing seeds from the weeds i've come to find in my yard. Three videos later from my research lead me to be most interestes in this product. Lawn care professionals in my area use this on the golf courses and neighboring property lines.

Slow, but amazing results
By Wallace on 06/03/2022
This herbicide takes a week or two to work, but works as advertised. I used this to spot treat crabgrass and dandelions in the spring. In a little over a week they have turned bright white without affecting the surrounding grass. Although not labeled, I also tried it on broadleaf plantain in newly seeded areas and it worked.

Tenacity works
By Gary on 04/19/2024
Well fellas I had the great idea to skip pre emerge to see if I really needed it. Unfortunately the clover and crabgrass loved this. It grew everywhere. Saw this product on you tube video. Bought the surfactant and die also. It killed all the weeds with a vengeance. Only thing you have to be patient. 1st week the weeds just laughed. 2nd week the weeds began looking like it got their attention. By third week they turned white and were dead. Now Bermuda grass coming up and weeds are no longer a problem.

Works
By Dan on 08/14/2024
The only thing I have used that kills actively growing crabgrass and I have tried almost everything on the market. I bought this house in the woods about 4 years ago. I have no illusions of having a golf course type lawn but I am not growing weeds and Tenacity is another item to use in my battle against weeds.

Tenacity is a Winner!
By Ernie on 08/16/2024
I bought this product because my new development’s HOA landscaping crew said I had to wait 2-3 years for all the crab grass and other non-desirable weeds could not be touched with weed killer because it will kill the new seed growth. BS! This worked awesome! Pics would show you white blades of witch grass and grabgrass dying, along with my new grass seed right next to them! Totally worth every penny!

works really well
By Susan on 10/07/2025
This stuff is the real deal. My backyard was covered in creeping Charlie, clover, and a good bit of crabgrass. Tenacity took out about 90% on the first go around. I had a bunch, so I figured it was ambitious to get it all the first time. My order came a day or 2 early. Which is always a plus.

Love it.
By B on 07/22/2014
Product appears to be a little pricy; however, the dosage amount needed makes it cheaper than products from the box stores and this product works better. The only draw back on this product is you have to be patient to start seeing results which I've experienced is about a week.

Tenacity
By Don on 12/03/2015
Worked beautifully to remove all forms of weed grass including bent grass and poa trivialis. Now I only have Rye grass left and the lawn is so beautiful people have asked if I just laid new turf! Would recommend this hands down, just be patient, it doesn't kill overnight and you do need to remove the dead weed grasses afterwards. Best to rake out the dead weed grasses once it has thoroughly killed them off before reseeding. The syringe is the only problem with the product, it binds up immediately. Toss it and measure out the liquid with a measuring spoon instead.

Works but be aware of results
By Rick on 04/20/2016
I've been using this on my maintenance jobs and it seems to be taking out Bent and other weed grasses. But be aware that you might kill more than you expected. I found that some of my lawns were over half bent grass and now I have some pretty damaged looking lawns. May have to reseed. It turns the dying plants a brilliant white color so may be a little shocking to customers.

Tenacity Kills Nimblewill Dead!
By Joe on 08/18/2016
Worked as advertised. 10 to 14 days after 1st application my Nimblewill turned white (kinda neat as you can see it working from across the yard). I have applied a 2nd application to make sure I got it all as this weed grass takes over, growing densely in areas where its gotten a foothold in my lawn. I used a surfactant (Hi-Yield Spreader Sticker) per label instructions. The syringe that came with the product is great. You don't want to waste a drop of this stuff. It's very effective but not cheap.

Nimblewill Killer
By Roger on 09/17/2016
Don't let nimblewill take over! In home turf it spreads in outgrowing circles and the effect is not good. Purdue Ag Agent advised dead kill or pick it out by hand - right! Tenacity has solved our problem. It took most of two seasons as I was very cautious not to over use. Advice about spraying a second time is excellent as you will miss some. Reaction time is longer than most and using a spreader is wise. Watch closely for regrowth and be careful handling. I'm a chem major; this is a great product but deserves care and respect.

Love Love Love this product
By Barbara on 05/22/2017
I had large patches of bent grass. Used this product. It took awhile to work. Transitioning from light green to white. Put on in mid April. Now the blue grass is growing thru the remains of bent grass. I will use again this fall if needed. Thank goodness for this amazing product.

Awesome
By Dan on 06/06/2017
I neighbor recommended this for my Kentucky bluegrass lawn which have several different annual blue grasses and some other fat leafed grasses in it. I have spot applied tenacity about 4 or 5 times and almost all of my annual grass has been eliminated. It is even working on the other weeds as well.
