Customer Reviews for Tenacity Herbicide

Works like a charm. If applied according to the label, it goes a long way. The syringe measure that comes with the bottle is bulky and wasteful (good for company who makes and sells the herbicide, bad for the paying consumer). Invest in a cheap single pan balance (mine cost $15 from Amazon. 0.01 gm accuracy) and weigh the herbicide. It is easy and assures exact amount/s. Colorant is also a must. Highly recommended. Will definitely buy again.

I USED TENACITY JUST OVER 2 WEEKS AGO. IT SEEMS TO BE DOING A GOOD JOB. THE GOOD GRASS IS FILLING IN. I'VE TRIED 3 OR 4 OTHER METHODS OVER THE YEARS. NONE WORKED. SEVERAL OF YARDS AROUND ME HAVE ALSO TRIED TENACITY. ALL SEEM TO BE DOING THE JOB.

I've been somewhat of a lawn maniac for a couple of decades. So I've used what I felt were the best products available to me and my knowledge. I've never been a user of weed and feed products and for the past 10 years or so have been more of a pump spray user focused on spot spraying trouble spots because it was apparent to me that the products I was using stunted the grass in the lawn as a side effect of killing the weeds and yet the weeds always returned. Tenacity in a very short period of time has completely changed that dynamic. With a new home build and yard a couple of years ago, I've used this opportunity to achieve a lawn consisting of a 100% tall fescue blend and knocking down the weeds on land that for over 100 years was a dairy farm had become a real challenge. Nothing I did seemed to provide the results I wanted. 1 month after 2 full yard applications of Tenacity and a surfactant at the label recommended rates of mixture I have a lawn with not a single weed, the lawn is coming in thick and rich this Spring and to such an extent that it is purely stunning. While working in the yard have had a surprisingly high number of neighbors stop and comment on how amazing the lawn is and am happy to share the handful of things I apply to my lawn and Tenacity is at the top of that list. I'll continue to do a couple of applications of Tenacity each year 3-weeks apart for the rest of my life in order to gain the preemergent barrier. As far as I'm concerned, and the result show it... Tenacity is absolutely my lawn Jesus. It's also my lawn wallet Jesus.

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.

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.

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.

I have an infestation of Nimblewill in my bluegrass besides various other species of grassy weeds and other typical annoying weeds (plantian, clover, wild violet, purslane). The local very popular garden expert suggested Tenacity. ONE little teaspoon of Tenacity plus 3 teaspoons of surfacant in 2 gallons of water in a pump sprayer, in one week ALL my test patches on the existing weeds and grasses show they are definitely dying, but NOT the blue grass! I may not need to do the second application, but even so if I have to, it's well worth it.

This product does the job! Kills crab grass slowly but does not hurt your St. Aug lawn. Product kills several other lawn weeds as well. Highly recommend!!!

I used it on my St. Augustine grass in S. Florida. About the only thing that turned white was the crabgrass, so it is very helpful for that. Spray your entire yard and the crabgrass will become very visible as white in a week or two. It's hard to see all the crabgrass otherwise. So I would recommend it for crabgrass, but not other nasty S. Florida weeds such as sedges or chickweed.

I used Tenacity, Serfactin and blue dye as directed. I applied it to crabgrass in a Bermuda lawn. In 3 days, I could see the crabgrass turning white. Success!! In a week , I will apply to new crabgrass. This was a perfect combination to kill a lot of crabgrass. I used a one gallon hand pump sprayer.

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.

I am so impressed with the product so far that I felt compelled to submit a review. I was skeptical about the low dose rate of this herbicide, but it's viscous content went very far. I used it in my tow-behind sprayer (15gal) with nozzle manifold to treat about 15,000 sqft. It has been about 14 days and my crabgrass-infested yard is very white with some of the crabgrass starting to die off. This has really illuminated the weeds in my yard because they all turn white. Second application to be made in about a week, which will hopefully kill off the crabgrass for good

My Centipede lawn in North Carolina had a lot of die-off over the cold and wet winter. Crabgrass filled in the bare spots. One treatment with Tenacity (and Dawn detergent as a surficant) and the crabgrass turned white - as advertised. I'll hit it again, which I'm sure will kill the crabgrass and allow my Centipede to overgrow the bare spots over the remaining summer weeks. Tenacity is expensive, but really works! A little goes a long way.

I have been using this most of the summer. It works very well on crabgrass and not so well on common purslane. It works pretty well on creeping Charlie. The best thing I like about this is that I have a lawn with bluegrass and with tall fescue mixed in. I asked an expert how to get rid of the tall fescue and he said roundup was the only thing. I tried this by accident trying to kill other weeds and noticed it affected the tall fescue with it getting white. I know it is supposed to be safe for tall fescue but if you repeat an application once a week for 3 weeks it will usually kill the tall fescue and leave the bluegrass looking fine. The next door neighbor even asked me to get rid of his patches of tall fescue and it is doing it.

Laid down product on 1000 sqft on a Saturday, 7-10 days later I have existing weeds turning yellow and white. Weeds that are just breaking the surface are almost immediately turning yellow and white as well. Currently I have a bunch of white dying pre and post weeds on my lawn. Product works great so far, just need to have patience and it will surprise you.

I bought this to kill nimbleweed and it appears to have done it's job. It's not cheap, but a little goes a long way, 1/2 teaspoon to a gallon of water. I also bought the surfactant and Mark It Blue to mix with it. Currently a satisfied customer. Shipping was quick.

It took 5 days to see any effect despite perfect application conditions. Took nearly two weeks to see the full impact of weed killing. One nice aspect this of this over other sprays I've used is how it targets weed grasses. The instructions are correct, a second application is needed 2-3 weeks after the first for complete elimination.

My yard had lots of clover, dollar weed plus other weeds and trash type grass that I had no idea way the were. I sprayed a couple days before a rain. Just like the instruction said, the weeds etc., turned white and died. Since I was treating just my residential yard, I used a handheld pump sprayer. I sprayed the spots I missed 2 weeks later, and they are turning white now. Definitely recommend this product.

I am a first time user of this product and I must say that it works very well. I sprayed on Saturday (7/11/2020) and I can visually see results after 6 days (Friday 7/17/2020). The weeds are starting to turn white. My lawn, however seems healthy, I am not seeing any discoloration as described by others. I recommend this product.

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.

I have been fighting crabgrass in my Centipede lawn for years. I found Tenacity and applied it per the instructions (spot spraying). As advertised, the weeds turned white, which made it much easier to identify them for the second application, after which they were gone. This is a terrific product!

A little hesitant at first,specially with the price for a small container. I have used all kinds of weed control on my centipede grass, Speed Zone Southern the latest. They all worked ok until Tenacity. This stuff so far is killing all weeds I have tried it on, and my grass is green with no ill effects. Heed the instructions as it is very powerful. It took it a couple of days before results started slowing appearing, leaves turning white. It instructs you to also add a coloring agent as it being so strong they want no overspray. Very impressed

Used Tenacity on my Creeping Bentgrass problem. Put down two applications and the Bentgrass appears to have died, turning brown while leaving the good grass alone. Since its nearing the end of the season I will wait until next spring to see if the Bentgrass returns and the good grass fills in the dead, brown areas, reseeding if necessary. If it does return then will definitely apply again to finish the job. This product worked like a charm and I would definitely buy it again.

My Tennessee "fescue" lawn was about 50% crabgrass. I applied Tenacity with a surfactant in early August according to label directions. By day 4 the crabgrass had turned white while the fescue seemed unaffected, I made a 2nd application of Tenacity on day 12, and by day 19 most (I estimate 90% or more) of the crabgrass was dead or nearly so and the fescue still appeared unharmed. As a post emergent crabgrass killer, Tenacity seems to work well. I hope it's as good when used as a pre emergent.

So far I have applied it twice (2 / 2 application cycles on different portions of my lawn) , only tip I will say is be patient. It takes 2 weeks before you see results, But it is awesome stuff, and well worth the cost. I have tried many other things but this stuff just works. I mixed 4 oz into 15 gallons of water along with the recommended amount of Surfactant and used it on brand new lawn and established lawn in MN, waited 1-2 weeks between my 2 application. So far im thrilled with the results, works as advertised.

Just as others have described, the bentgrass begins to turn white in a week to 10 days, then dies off. The surrounding bluegrass is unaffected. This is my first application and I see a few places that were missed so will go over it again. It was mid-August when applied. Previous applications of "round-up" did not result in satisfactory control because the bentgrass always came back up from over the winter. Hopefully the Tenacity takes care of it. It's good that I have enough left to do another application in the spring.

I had nimblewill spreading across my yard at a rapid pace. Spot treating with Tenacity took care of the problem. It does take a while for it to work, so be patient. But it does work and won't kill other grasses!!! It destroys everything else you don't want in your yard, too. Great stuff.

Tenacity not only kills the nimblewill, but does and excellent job as a post emergent on crabgrass. It actually kills the crabgrass quicker than the nimblewill.

"LOVE" this product, prior to it being available to consumers. Getting bentgrass out of my Kentucky Bluegrass lawn was a nightmare. Had to kill the bentgrass, dig up huge brown bentgrass spots, put down sod. One year I put down 45 rolls of sod. Only to have the bentgrass return to the spots I missed. Each Fall I spray entire lawn X2, this herbicide targets certain weeds, the rest of grass is left alone. I just have spots of white (weeds dying). Spray entire lawn in the Spring, just too make sure I got them all. No more problems with bentgrass!
