Customer Reviews for Tenacity Herbicide

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.

Large patches of poatravalis in my fescue has been driving me nuts. Applied tenacity at full rate with a surfactant and 7 days later poatravalis is almost completely white and growth rate and seeding has almost stopped. Second half rate application to follow. So far only slight damage to fescue has occurred. Applications were done while temps were in the 70's and avg soil moisture.

Don't let the small container size fool you - a little bit goes a long way. It needs a non-ionic surfactant to be mixed with it, so be sure to order some when you order this product. It works by stopping chlorophyll production in the plant, so as the target starts to die, it turns white and your lawn looks unusual for a while. The fact is - this herbicide works on some tough to eradicate plants. It takes two applications.

I bought for Chickweed control and fall Chickweed pre-emergence. Will not see results until the Spring. On the plus side it has turned quite a few of the other weeds/grasses in my yard white. I just hope they die and do not come back. I used in a 2 gallon sprayer with non-ionic surfactant and a marking solution. Takes awhile to do the whole yard but well worth it if it controls the weeds and germination seeds better than the big store brands - Scxxts etc... I will re-apply in mid March and try for pre-emergence control of anything I might have missed.

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.

I purchased and used the Tenacity Herbicide for my 1 acre lawn and followed the directions provided by mixing 1 tsp per gallon of water and adding surfactant. First, the price at DoMyOwnPestControl was the cheapest. My local nursery in Northern Virginia tried selling me the same product for twice the price. Second, I chose this product as recommended by my local nursery because the Ortho Crabgrass Killer spray bottle, which attaches to my water hose had not worked 1 month prior. Third, after using the product, I noticed that the crabgrass and other weeds started to eventually turn white; then died. Within 2 weeks of using the product, I mowed my lawn, dethatched, core-aerated, oversed, and topdressed. Therefore, it is too early for me to determine how long it's effects will last. Overall, I will rate this at 4 out of 5 stars. It is a great product, does the job, is certainly cheaper at this website. The remaining star is what remains to be seen in the future...

Within the first two weeks, I noticed that some grass was turning white, which, according to the instructions, was supposed to happen. The net grass is still brown, and I am hoping after the second treatment, which was done a couple of days ago, will do the trick. I bought the product specifically for bent grass, and I hope that it works.

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.

Upgrade my review to 4 stars as the Tenacity appears to be working and I have applied a 2nd application after 3 weeks. I thought it was outstanding that I was called by Do My Own Pest Control and was offered a partial refund for the product that leaked out and review the other comments in my review. Great Customer Service!

The product works very well for crabgrass control, preforming best with two applications followed by a light rain. It takes about two weeks to see the full effect but results are very good when other products have failed even with repeated applications. The crabgrass turns white, then dies out to brown. Very pleased with how far the concentrate goes.

I rated 4 star since I still have to followup with two treatments, but I wanted to share that some of the nimblewill is already turning white....losing its chlorophyll. Once I am 100% done and it works I would go to 5 stars, but don't know that yet. Some expensive, advise USE AS DIRECTED, but if does work, it is worth it! Do use in conjunction with the Non-Ionic Surfactant for Herbicides. You can buy that here too!

I have tried pulling bent grass out, also treating it with all types of killers and nothing seemed to work until Tenacity. It takes a while to see the results, but it definitely works! I'm just hoping that it kills the root and doesn't return!

This product has gone beyond my expactions. I like the idea the weeds turn white so you can see what has been missed.many neighbors has seen it work and ask about it. They like the idea it does not harm their lawn and see the results.I like the fact you can put down new seed with no harm to the seed.

In nothing I read did it mention that this was a very slow acting herbicide; as in weeks versus days or hours. Even at the recommended dosage, a simple spray will kill (crabgrass, and wild strawberries were my targets). I'm questioning its effectiveness at pre-emergent control... As a test I did the following: 1) Spray entire plot with roundup to kill of existing grass, clover, and wild-strawberry 2) On half the plot I used a full sterilization technique (cover with clear plastic for two weeks to kill off any seeds, etc.), 3) After the two weeks I tilling the entire plot. Then once I tilled the ground I sprayed the Tenacity then planted my Kentucky Bluegrass seed: the wild strawberry came up on the unsterilized side. It came up and the leaves turned immediately white, so it is working, but postemergence not pre. Using this on an existing lawn, as others have mentioned, means that you're not only gonna have ugly weeks in your yard, you're gonna have ugly TOTALLY WHITE weeds in your yards for about 2-3 weeks. I would say this is best for a newly planted plot, or if applied to existing lawns, right before leaves drop (or right afterwards if you rake up leaves), and then again in the early spring.

Seems to be more effective than others but we haven't won the battle yet. Make sure you add the spreader so you dont waste time and money.

I applied Tenacity last week and the weeds are whitening up. Still waiting to see if they die all the way. I did an application on part of my lawn too early in spring when the temps were still getting into the 30's at night and I don't think that application worked. Still another week or two to go to see if the weeds completely die.

Tanacity works very well however the cost is prohibitive for large properties. I'll buy more when the cost is seriously reduced.

strong stuff! A small amount makes a big dent in weeds, but doesn't kill the grass. It takes a few days to see results, but it's definitely worth every penny!

Sprayed this mixed with triclopyr the other week to kill some random weeds along with some ivy. My fescue (tttf) is freaking out from it and the spots sprayed have been light green/white for almost a week now. The weeds themselves have started to die off. Until the grass recovers though, I've got some nasty looking spots in the yard

I am very pleased with the Tenacity application with surfactant and dye. Easy to mix. I marked off 5' x 100' areas and treated these as I covered my lawn. My system and application were all but perfect. The syringe was a real disappointment. I could not pull product into the syringe. It may have been defective, but it would not work for me. I had to use other measuring devices.

A little goes a long way so the actual cost per dose is a bargain

I read several reviews of the product before ordering. I followed the instructions in applying, but it took over 5 days to see any effects ( rather than the two I'd been led to believe). So far, I'm seeing significant die back of the crab grass. A second dose seems advisable, so I'll tentatively say that I'm happy with the results..........

It too quite a long time, but it has killed the crabgrass. You do need to use a fine spray and cover it really well. I'm going to use crabgrass preventer next spring. It's been extremely bad this year, so hopefully I can get it under control now.

Product worked as advertised. Killed off the crabgrass without bothering the rest of the lawn.

5 stars for domyown.com. Tenacity had yet to work. Second application today. Hoping for better results.

I only applied it 2 weeks ago and it seems to be working. It takes bit longer then most of the other herbicides that I have used in the past. Don't get discouraged if a week goes by and you don't see any change, be patient Can't say much more until I see the end result.

Crabgrass has been overtaking my lawn and just about everyone else has the same problem in my neighborhood. Tenacity attacked and killed most of the crabgrass pretty quickly. It is working on other weeds at a slower pace it seems. I do believe the lawn needs a second treatment which I will apply before Sept. 1st. I will update this review after that. I used a surfactant and a dye with this product. Looking forward to using Tenacity as a pre emergent next spring.
