Customer Reviews for Tenacity Herbicide

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.

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.

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!

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.

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.

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.

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.

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?

Finally a product that claims to handle "Bent Grass" that really does. Wound up with an infestation of a creeping bent grass from a landscaper - tried product after product. Tenacity really does work, about a week after application I started to notice white spots in the lawn. The treated areas of bent grass grew whiter yet the regular grasses stayed green. After a short time the bent grass started to wilt.

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.

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 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.

Used the Tenacity with the lawn tractor and pull behind 15 gallon sprayer to treat our approx. 1/4 acre front yard. It destroyed the nimbleweed in two weeks, leaves turned white so the lawn looks a little funny right now. We did a second application as instructed and will be sowing new grass in the near future.

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!

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.

A unique set of features sets this herbicide apart from others. Tenacity is both pre-emergent and post emergent, it works on both grass and broadleaf weeds, and it won't affect grass seed germination. Excellent product when used on a newly seeded turf to prevent weed competition.

I have used this for several seasons now. It kills the Bent Grass that comes in from the gold course I back up to. One teaspoon per gallon does it, so it lasts a long time. Doesn't harm the other grasses. Do My Own Pest Control is easy to work with. Fast delivery.

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.

Bentgrass began turning white and Nutgrass brown a week after the first application. Read the directions for applying, must be water in after applying. Costly, but for the small amount you mix with water an 8oz bottle will last a long time.

Tenacity did it's job for my lawn. I put down 2 applications and I am going to spot treat a few spots that I want to make sure my bent grass is gone. The grass is already growing in the areas where the bent grass has died, and my lawn only look bad for about 4 weeks. It now is the best looking on my block and is thick and dark green. I also sprayed it on my neighbor's crabgrass along the edge's were are yards meet, and it killed it in 2 weeks and is gone. Amazing stuff. I have not seen one weed in my yard since putting this tenacity on. Now I have areal big challenge coming up with my brothers yard going to use it on his, that will really tell me how well it kills weeds and other grasses.

I applied this a week ago to creeping bent-grass and an occasional clump of crabgrass. As promised, the grasses are turning white. I'm sorely tempted to reapply after a week but will wait one more for the second application. And for those who note how expensive this is, it's a dollar an application for 2 gallons of spray ... compare that with other herbicides.. and it's low toxicity makes it a winner...

I used this product 4 weeks ago to some of my problem areas as far as crabgrass, creeping charlie and nutgrass. It did the job! Make sure you follow the directions as far as the 1 teaspoon per two gallons though. My first batch I did not measure and it took awhile for the grass to bounce back. Definitely turns the weeds white but don't worry it bounces back.

I just put down my second application and so far I am very impressed. I'm putting it down with a 2 gal. tank sprayer. It has "done a number" on my bent grass and that is what I was primarily after. As a bonus, it is also wiping out my wild violets. I have been trying to kill those for about 10 years. I'm anxious to see what things look like in the spring. Has this really eliminated the patches of bent grass (and violets) or are they coming back in the spring?!?

I purchased an 8 oz bottle of Tenacity to control the nimblewill that is beginning to take over my yard. I applied it according to instructions, and it has begun to show results after about i week.

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.

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.

This product has done a great job of knocking down some very tough weeds in my Kentucky Bluegrass turf. Waiting to see how the residual controls as a pre-emergent as the weather warms up.

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.

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.
