Customer Reviews for Tenacity Herbicide

Seen some you-tube presentations on this and decided to give it a try. I used for spot-treatment and my observations: - takes at least a week to see if it's working - it's marginal when it comes to taking out mature crabgrass - For the cost/hype, I had expected it to be able to handle more weed varieties.....which it did not. There are other similar products that I expect to try once I use up this bottle

i bought this product and used it twice over a seven week period on my entire lawn. I am very disappointed. I was extremely careful to use it exactly as directed and made sure to use when there was no rain in the forecast for 2-3 days (turned off sprinklers too) and with a recommended surfactant and dye to make sure I didnt over apply with a four gallon backpack sprayer. It did turn my grass white for a few weeks and killed a few dandelion weeds and patches of something else but didn nothing to the crabgrass or clover. I may try one more time in september but next year I'll try something else with dicamba as an ingredient or use it in a tank mix with dicamba. (I have a sentimental attachment to banvel.)

Followed the instructions but It did not work the way it should. Only 20% crabgrass died. Used it second time with double the recommended quantity and even than it did not kill all the crab grass. Used with surfactant and blue dye.

Sprayed as directed and added another product to make sure that is stayed on the weeds. Here it is almost 2 weeks now and still not much change as I would have expected. Especially, given the cost of this product. Wanted to get away from that deadly RoundUp garbage product. At least that made the weeds dry up and disappear.

I purchased this stuff in effort to kill off random patches of bentgrass. The product does warn that if you over apply then it may cause temporary bleaching to your good turf. I am here to warn you that while it did a good job of killing off the unwanted Bent grass, I am now going on week four of a nearly all-white lawn. My TTTF was dark green and healthy all season. And after applying two applications EXACTLY according to the label, the whole lawn looks smoked. I've since hit it with starter fertilizer and organic, plus liquid Humic to try to force some growth and regain my green grass. It's slowly coming back in sections but I am sincerely concerned for what's to come this fall and even next year. In short: don't believe the hype. This stuff is very expensive and does legitimate damage to your established turf.

I read lots of good reviews and gave Tenacity a try. I followed the recommendations to the letter, surfactent, dye etc. I hadn't mowed for two weeks before application and didn't mow for a week after. I waited for the weeds to get white and die as the reviews promised, but it never really happened. There was some lightening of some weeds (not all) but they didn't die. It's been about a month since my application and it just isn't going to happen. I was trying to kill crabgrass but the crabgrass was more tenacious than the Tenacity. I'm about a $100 bucks lighter and the crabgrass is laughing at the Tenacity.

This pre-emergent weed killer is overrated. I applied two different applications 3 weeks apart with limited to no results after 5 weeks. Following directions exactly 1/2 tsp per gallon along with 2 tsp non ionic surfactant and turf marker. Nothing. Spend your money elsewhere.

After reading the instructions, I mixed the herbicide at double the strength suggested and my wife applied the mixture to some grasses she wanted to remove from our landscaping. Nothing died.

I did two applications 2 weeks apart. It's Killing the weeds...very slowly, However it also bleached good grass. Looks like my yard is dead and I'm surrounded by dark green lawns. Neighbors think what the heck is up with it. lawn bleaching reached max in 3-4 days. From what I read it could be like this for a month or more. I'll be switching to other weed killer that does not make the lawn look so bad.

I used a 3 gallon backpack sprayer to cover about 1/4 acre front lawn. It took 10 fills and mixes according to the recommend 1-1/2 tsp Tenacity to 3 gallons of water recommended and a whole lot more time than with granular products and a spreader. It seemed to turn sections of grass whiter than the chickweed I was trying to eliminate. Jury is still out on the effectiveness, but I would try something else next time

Not effective..... in the past few years I used it on different weeds, never effective, and I exactly followed the instructions on how to use this herbicide. For people think it's effective, it's better to show results in pictures, cuz it never worked on my weeds.

I purchased tenacity and applied on my lawn. First application was done but about 6 hours after it rained. Waited a few days and applied again, a few days after the weed leaves started to turn yellow, but not died from the root, as a few week after they grow back again. Also, tenacity seems nit effective to some weeds at all. Not sure what to do, as I wanted to reseed shortly, but would like to get some space for the seed.

It killed my marathon 2 sod as well as weeds, so what was portrayed as an easy fix has now become a large project. Disappointed.

My lawn has had a crabgrass problem for the last two years. Tenacity seems to be the answer. I sprayed several areas of the Centipede grass to see if it is as effective as the advertising states. After about ten days the sprayed area is not doing well with the grass turning totally brown and it appears it is dying. I mixed it 1/2 teaspoon per gallon. Perhaps the grass will come back but I have my doubts. The spray dye was worthless. When I sprayed it, a little bit of blue tint could be seen but minutes later I could not tell where I sprayed. I read other reviews that stated the same thing.

I hired a landscaper and asked him to use the Tenacity that I purchased. I watched a YouTube video that highly recommended the product. While the crabgrass visibly died back, all of the other weeds on my lawn flourished. The landscaper has since put down a granular product he prefers. I immediately noticed a difference. Since we are already in October, I didn't feel we had the time to try a second application of Tenacity because we still want to dethatch the yard, aerate, and seed. I may consider trying Tenacity as a pre-emergent in the spring.

I bought the Tenacity Herbicide along with the Spreader Sticker and the Dye. Instructs are clear and with the included syringe it was easy to mix and spray with my Husqvarna 4-Gallon Backpack Sprayer. The first application did have no effect at all. Further applications killed some of the weeds, but did not get rid of the broad leaf grass. In fact, after all the grass turned white, the crab grass was the first to recover. After another application, I have spots where nothing but broad leaf grass remains. I am awarding 2 points because it kills some weed. But there are a lot of cheaper alternatives out there in the market. For the purpose that I bought this, it did not work at all.

Followed instructions to the "T". Applied to clover as described. Nothing happened. My St. Augustine grass turned colors but that's about it. I believe the clover called over its friends and had a party. The surfactant and dye worked but the Tenacity not so much.

Takes too long to work. Takes too long to start working, then you have white patches for it seems like weeks. There are much better, quicker acting treatments out there. I tried it twice. Same results.

Spent the $ sprayed the weeds, twice, and the clover just laughed and mocked me. After two applications the clover had leaves showing some damage from the application, but overall they just carried on spreading here there and everywhere. Very disappointed in the product!

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?

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!

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.

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

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.

I had plenty of rain in the week after Tenacity application. Within 5 to 7 days the weeds, including crabgrass, buffalo grass, clover and other broad leaf plants began to turn yellow and then white, and die. Where the application was heavier the color change was more dramatic. I seeded with fresh good quality seed, a blend of the new varieties of K-31 and other cool season home turf grasses. As of 16 days I have very little new grass appearing in my yard. It has been a wet spring in Chattanooga,therefore water is not the problem. I am beginning to wonder if the claim that you can apply Tenacity and seed all in the same day of two is really true. I hope so; the seed costs me almost $1,000. If the grass seed does pop up I will be sure to add that to this note. As a herbicide, it seems to be doing well. I am going to wait to apply the second application of Tenacity until I see what the grass seed really does do.

I'm using this on bluegrass lawn to control wild violets, crabgrass and nimble-will (sp?) The action is terribly slow and then requires a second application prolonging the desired results. Weeds do seem to be declining except for clover which is relatively unaffected. The white spots throughout my lawn are really irritating to have for 3-5 weeks AND it is really expensive.
