I had a lot of weed grasses in my yard and they were invasive and spreading over the whole yard. Tenacity targets weed grasses and kills them while leaving the rest of the yard in tact and that is exactly what it did. All of my weeds are dying. One thing you must note is that this herbicide needs to be watered after it dries on the plant so that the plant takes it in. It will not work if you just spray it on and don't get rain or water it for a couple of weeks. It's pricy but I know of no other chemical that will kill weed grasses and leave what you want, alone.

A Miracle Herbicide!
By Margaret on 08/14/2012
I had a lawn that was completely taken over by bentgrass. I used round up on the lawn and put in an entire new lawn. All was well for a year or two. Then the the bentgrass came back in a few isolated areas. I would have to round them up at the end of the season and reseed. This went on for a number of years. When I learned about Tenacity I was thrilled and gave it a try. It works wonderfully! Yes it is pricy, however it beats having to round up the bentgrass, clear it out, put down more top soil and reseed. Try it...you won't be disappointed.

Great product! Does exactly what it advertises!
By Debi on 09/07/2012
My mom completely re-sodded front and back lawns and within 3 years it had been invaded by bentgrass. My new lawn was hydro-seeded 5 years ago in a new subdivision that used to be a golf course. Our methodology was to use Roundup in the fall (when the bent grass really seems to take off in growth) and then reseed the large killed off areas, hoping that the Roundup did a thorough job in killing the bentgrass. This becomes very tedious every year, not to mention the expense. We waited a few years for Tenacity to be available to the public and have both been having great results with the product. The good thing is that the remaining blades of good turf remain green in the kill zone. That gives me hope that I may not have to reseed, just wait for the good turf grass to fill in by itself. Our lawns are a combination kentucky blue and fescue blends. My only complaint is that the product is so concentrated and thick. The high concentration makes it even more critical to measure accurately! Not too crazy about the enclosed syringe measuring device. I feel it is too difficult to use and the potential to spill is high. I would love if there could be a more diluted Tenacity product to purchase for the average homeowner. That would make the product easier to measure, plus ensure a bit of wiggle room on the measurements?

No more Crabgrass!!
By Rob on 08/23/2012
This product really works. It does take time, so be patient. I still have to apply the second application to finish off the Crabgrass!!! It won't take much, the plants are almost dead now after 2 weeks.

Appears to be working!!!!!!!!!!!!
By Del on 06/17/2012
I was skeptical about whether Tenacity could kill the Nimblewill in my lawn and still leave my Blue Grass and Fescue alone. It's been 2 weeks since the first application and it appears to have definitely wounded the Nimblewill. The second application was applied yesterday, so we'll see if it kills it or not. It's a "pricey" chemical, but is easy to use and hopefully effective. If it works it sure beats Roundup and reseeding.

Obvious it's working...
By William on 08/15/2012
Lawn was overrun with a variety of weeds (bermudagrass, Nutsedge, clover). Applied at the higher rate (8 oz. per acre but converted down for residential lawn size) as directed, putting a little extra directly on problems spots. Day Four: Noticed large weed patches turning a bright green Day Seven: Weeds turning white and some turning brown, curling and clearly dying. Good fescue grass appears unaffected and fine.

Slow but sure...
By Dan on 08/09/2012
Don't expect results immediately. I used Tenacity with a surfactant. I wasn't sure at first if the herbicide worked. After about a week, the Nimblewill started to turn white. None of the surrounding grass seems to have been harmed. Great product!

Applied Tenacity to eradicate nimblewill about 10 days ago. The weed is turning white and dying as represented. I am very encouraged, as the weed was overtaking an otherwise decent lawn.

Finally, a way to kill Creeping Bentgrass
By on 09/05/2013
A year ago I killed my front yard (90'x80') with round up, tilled in compost and added about 8 yards of topsoil because it was infested with light green areas of poor quality grass which I know realize was creeping bentgrass. Starting late July this year I noticed areas of the lighter green grass popping up again so after some internet research I found out about Tenacity. This product is amazing! I mixed it up a week ago and applied with a 1 gallon tank sprayer (I recommend mixing 4 to 5 gallons at a time because Tenacity is thick and hard to measure small amounts) and sprayed entire front lawn, a couple of days ago I noticed the new growth on the bentgrass is white and yesterday even more of the bentgrass is losing it's color and turning white, the best part is the good lawn grass is still looking great, my lawn is a 33/33/33 mix of blue, ryegrass and fine fescue mix for NE. Don't be put off by price, this stuff works and goes a long way!

no more crepping bentgrass
By on 07/12/2013
Finally a working solution to crepping bentgrass. I was fighting bentgrass for the last 4 years and it always came back even after killing everything with roundup and redoing the whole lawn. This really works and after 1 week you can see first results. Make sure you use a surfactant.

I have used tenacity in several situations, and overall, it has been fairly effective. I originally purchased it to control nimblewill, post emergence. It was only moderately effective, although I think the nimblewill already had too much of a head start. The mature nimblewill did have white leaves, but I did not see any effect on the plant growth (or death). It has been effective against crabgrass, also post-emergent. I have also used it against Japanese Knotweed, post heavy injections into the stems with Roundup concentrate, on the regrowth after 3 doses of the above. There has been whitening of some leaves, but I have only today retreated this patch of one of the worst weeds I have ever seen. I am hopeful that the 2nd treatment will be more effective than the 1st one. By the way, my wife really didn't like the white patches in the lawn!

Death of Nimblewill grass
By David on 10/02/2015
It took a while, but the grass and other weeds are all white/dying. I used three teaspoons of "Dawn Ultra" & one teaspoon of Tenacity to two gallons of water, per a study by Ohio State University.

By Bill on 09/18/2012
I'm not sure I used the right dilution. Instructions only cover one acre. How about mixing in oz/teaspoons per gallon for hand sprayer. I used a little over one teaspoon/gallon. Have soon no results but maybe I'm too impatient. Can you help?

After trying everything to try and get rid of nimberwill in the yard, I was just about to use another application of roundup when I discovered Tenacity. So far it seems to be working and is very effective on crabgrass as well.

I have been searching for a product to control both broadleaf and weedy grasses in my centipede yard in eastern NC. The initial price of the product was difficult to overcome, but I am glad that I tried the product. Spot treatment for post emergent control requires only 2.5 cc /gal of Tenacity and I added a surfactant. Within 3 days I could see white tips on the treated areas without any damage to the centipede. At 10 days the areas are browning, again without any damage to the centipede. Treated areas included; Florida betony, mimosa weed, bahia, crabgrass and a number of others. Looking forward to using this product on the Florida betony during the fall and spring blush.

Only works temporarily
By Gary on 09/10/2014
It did work as advertised but the bentgrass came right back 100% in the same spots within 30 days. This product was applied professionally for two applications.

Had quack grass starting to take hold in my yard. Used Tenacity and after 5 days I can already see the product working. Quackgrass is turning white and the surrounding lawn looks good.

Tenacity Kicks Nimblewill Butt
By Greg on 10/08/2014
Even the small container of the selective herbicide goes a long way for spot weed control as you use a miniscule amount of product, via the included syringe, for a pump sprayer. One needs patience as it takes an application, then another a couple of weeks later, for the nimblewill / nimbleweed to turn color. it will also turn neighboring grasses white as well, yet they will grow out according to the instructions. I am about to start re-seeding the thick areas of weed that will now pull out easily as it is dead.

Never ending battle of Bentgrass
By Kathy on 10/23/2014
I heard so many great things about Tenacity that I needed to try it to remove my lawn of bentgrass. This is my 3rd application and I still have bentgrass. It does work but expect at least 6 weeks of an unsightly lawn with each application. You will also have to keep reapplying it so your lawn will look unsightly again. Also it is costly but you only need 1/2 teas per gallon of wate.r Could be because of the amount od bentgrass that I have but I wish it would work quicker and more effectively. One plus, is that it does not damage the good turf.

Works great to remove bentgrass
By Jp on 09/24/2014
I had a large section (about 4,000 sq. ft.) of Kentucky bluegrass/fescue/perennial rye lawn which had long been seriously infested with creeping bentgrass, as well as some bermudagrass or nimblewill (I can't tell the difference between them) and wild violet. I used 2 applications (at the label recommended rate) of Tenacity, 10 days apart, starting the first week of September. I applied as a spot spray with a backpack sprayer. A week after the second application, I did indeed have large patches of white lawn. 10 days after the second application, The bentgrass appears to be completely dead, and the lawn grasses appear to be slowly recoloring. The Tenacity had little to no affect on the wild violets or the bermuda/nimblewill. It did nail a few plaintains, dandelions and some crabgrass. Since it's late in the season, I'll go back to hitting the wild violets and bermuda/nimblewill with Acclaim/Triclopyr, which does work well in a single application. Although the Tenacity is quite expensive, I've never seen anything else work like this on bentgrass. DMOPC.com's price for Tenacity was less than half the price from my local retail supplier. Along with that, a little of this product goes a very long way.

Nimble weed control
By Bem on 10/05/2014
Put it down at half strength to control nimble weed. It appears to be killing nimble weed but the tall fescue doesn't look so good as well. Everything turning white, Hopefully grass will come back

Tenacity for crabgrass in blue/rye grass central IN
By on 06/16/2013
I usually use pre-emergent crabgrass (CG) control, but I needed to fill in bare spots from last years drought. I used Tenacity at 1 tsp per gallon with 3 tsp of non-ionic surfactant, i.e., 5 oz per acre as a spot treatment... difficult to do since CG is so ubiquitous. It seems to kill young CG well after 3 days dry & sunshine but washes off with rain after about 36 hr requiring re-treatment. It will kill other wide blade grasses (mature ones) that you may not recognize as CG and it's a little rough on newly emerged ryegrass in my hands at this rate. I just keep hoping to knock the CG back as the season continues.

I decided to buy this as my Niblewill problem had gotten so out of control I would have had to replant half my lawn. Mixed according to directions and I'm watching the darn pest turn white. Also working on my clover, crab grass, and other broad leaf weeds. Used a 2 gallon tank sprayer to apply. So far so good.

2 applications at 2 weeks apart - CRABGRASS DEAD! I used half bottle for my front lawn - about 100 x 100 feet (along with Turbo surfactant) in a hose sprayer. This stuff is darn good - grass (mix of blue, fescue and rye) all good - just the crabgrass and other weeds. Worked better than Trimec - which did not seem to do much at all. The crabgrass first turned white - and now is starting to die out and getting brown. I will now rake or pull out the crabgrass stubs to make room for new grass seeds in Sep. Very pleased.

Tenacity - great against crabgrass
By M on 09/26/2015
Crabgrass was rampant in my backyard. Sprayed once using a tank sprayer and surfactant as directed and virtually all of the crabgrass is now dead. Great product! Also appears to be working on what I call "wire grass", not sure of the technical name but it's weedy and grows low and wide like a rope or wire.

Tenacity is excellent stuff! While most standard herbicides at the big box stores will take care of the easier to kill weeds Tenacity will get rid of the tougher ones. It really did a number on poa annua and crabgrass in my lawn with no permanent damage to the turf. I did get a little bleaching in my tall fescue but the color came back and all is well. Don't expect overnight results. Tenacity takes nearly 2 weeks to show visible results. Haven't used it as a pre-emergent yet but plan to this fall during my overseed.

I've used Tenacity for a couple of years. It's a good product. Very safe and easy to use. Best of all, it works on Bermuda grass and Nutsedge without damaging the regular grass. It can also be used in conjunction with overseeding or new seeding. For larger areas, I use Trimec since it is less costly per gallon, but for spot spraying and Bermuda, Tenacity is the most effective. Too, the price from domyownpest.com was the best I found.

Only Herbicide That Works
By John on 08/05/2015
After trying numerous products to rid my lawn of creeping bentgrass I discovered Tenacity online and decided to give it a try. Within a few days the very invasive grass turned bright white and eventually started to die. I couldn't be happier. It's a little pricey, but a little goes a long way.

Worked as Expected
By Mike on 10/20/2014
This is a product I have been looking for to control my poa annua and creeping bentgrass. After I treated it took awhile, but sure enough my weeds stared turning a whitish color. It took a couple weeks to start seeing results so you have to be patient. I have just applied a second treatment and can't wait for next spring to see final results.
