Customer Reviews for Tenacity Herbicide

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.

This weed killer does a good job killing crabgrass and goosegrass. It does take at least seven days (as it says on the label) before the weed starts turning white. It is also a good idea to spray a second time (two to three weeks after the first one) for optimum results. It did not hurt my tall fescue grass.

The Tenacity didn't work on the grasses we wanted to get rid of. I wanted a kid and pet friendly solution, however this didn't work. I even sprayed area twice and made second batch stronger!

Used product, within two weeks the Poana in my lawn was dead.. there was discoloration to the lawn but it's appears to be returning to its natural lush green color. Plan to use again in fall prior to overhearing. I would recommend.

Worked great on my fescue lawn in Tennessee. It killed most of the weed in my lawn the first application. It will bleach your grass for a couple of weeks. Don't panic it will recover.

Until I heard about Tenacity, I thought the only way to get rid of crabgrass was to dig it out which was only partially effective and left holes in my lawn. Tenacity kills crabgrass in place allowing the normal grass to fill in as the crabgrass dies out.

I followed the instructions to the letter and saw very minimal change. I mean the dandelion died quickly but that was it. I did notice a small percentage of the creeping charlie leaves get a speckle of brown on them but they certainly didn't die. Its been 2 full week and we have had rain in that course of time but as of yet I don't see the value in this product that accurately reflects it's price. I just put down a second application and I stepped up the dosage by 50% so we will see. If this round doesn't get it I going to just have to pay a local company to rid my yard once and for all. I mean it look like it'll be months and bottles of the tenacity before this product work. I'll update if something changes but if not, well you get the picture.

After applying the product started noticing that the weed was turning white and my blue grass as well, if I would've known this I wouldn't applied the product since it's been 2 weeks and my good grass still white, I thought the product was going to target and kill just the weeds.

I am a novice at lawn care, and I learned about Tenacity through watching hours of youtube videos. I was initially skeptical this thing would work. I am here to report that after around three weeks, all the weeds in my yard have turned white. I am not exaggerating; the weeds have become white like the bottle the product came in, and the grass was not affected. I just have to wait to see if the dead weeds are permanent. I think Tenacity is a great product, and I would recommend it to anyone.

Highly recommend. I sprayed and we got an unexpected rain shower. However, it still worked. I will warn people that it will make your yard lose it's curb appeal with the yellowing spots. But I am seeing my clover and crabgrass turning yellow and dying.

Worked well on crabgrass which was the reason for purchasing. I also used the Hi-Yield non-ionic surfactant with the Tenacity. I should have used half the rate of Tenacity though. It even killed my lawn (fescue) as well. Lesson learned. It does take at least 7 days before you start seeing results.

It killed a lot of weeds in my lawn. I am using it all over my lawn and only use 1/5 of an ounce when add the water into my sprayer. I now want to add the color and so I can know where to is going. What else do you have that might interest me. Do you have a magazine that you can send me?

This year decided that i wanted to take my lawn back and have that beautiful full lawn again.... So started doing research and came across DoMyOwn.com and Tenacity. My first step given that my first application was mid May 2020; and my first objective was to get rid of all the broad leaf weeds and the crabgrass. I used a 4 gallon backpack sprayer that I bought from DoMyOwn and used the surfactant and blue dye (the blue dye is a must and very helpful) to see where i was spraying. I "DID NOT" see results during the first week and was skeptical.... However by day 7, 8, 9, 10... could see the crabgrass and other weeds starting to dye off. Specifically the crabgrass which is hard to see sometimes, now easy as it turned white by day 12...... I put another application on 20 days later, and plan on doing that again 20 days later for a total of 3 applications (i had a lot of weeds). The thing i like about Tenacity is that i was able to apply seed in May when i put that first application down, so over the last month that young grass has come up and filled in a lot of the bare spots from last year. In conjunction with Tenacity i applied Q4 to kill of the broadleaf..... Both work great and i have truly seen great results. If you decide to use tenacity, follow the directions, "USE" the little syringe to measure and dont forget to measure out the area (square feet) to ensure you are not "Over or Under" applying. For me, some of my lawn turned a little white, I think i might have over applied...... Not a big deal given it goes away after a month; the key is getting the WEEDS out in preparation to seed this fall. For the first time, i will have ZERO crabgrass and no weeds. It is the crabgrass that is hard to kill and see...... ********Also if you applying Tenacity in HOT weather, use the "Herbi-Oil" it will help stick and stay on the weed before it evaporates in hot weather...... That is something i missed and will make it more effective. Best of luck!!!!

This product is totally worth the price. It works better than any broad leaf herbicide the I have ever used. It usually kills in one application and is relatively gentle on the surrounding turf grass.

I bought this with doubt being It was based on watching some YouTube videos and other people's reviews. I have to admit that once I've applied this to carpet grass and other weeds, it did what exactly the lawn care but said. I'm amazed at this stuff and truly works. Must wait a few days to see the results but works for me and my st Augustine grass.

Very much liked the way it selectively took out the nimblewill grass that had invaded my lawn.

This stuff works great on crabgrass and sledges, but doesn't work so good on wild violets or tall fescue weeds. Overall, a lukewarm herbicide.

Despite use of pre-emergent herbicides we still had patches of crab grass. Two weeks after spraying these plants are turning white while fescue is untouched.

My lawn has been infested with bent grass for a number of years. The people at our local garden center could only recommend burning it off with roundup. Within a week of application the bent grass is dying and turning white. Now I can kill the new outcroppings before they get established and not have to reseed. This also kills some other stubborn coarse grasses and crab grass. Very satisfied. Highly recommend use of spreader sticker and blue turf mark with this product.

I had been seeing a lot of you tube videos regarding tenacity and its effectiveness. So I decided to order it and see if it actual would work on my lawn (mostly Kentucky blue grass and Fescue) as a post emergent herbicide. Weeds like crabgrass, plantain, chickweed, spotted spurge and purslane were starting to take my lawn over. I followed the direction and mixed 1/2 teaspoon tenacity per gallon along with adding in 1 1/2 tsp of Hi-Yield Spreader Sticker Non-Ionic Surfactant and finally Turf Mark Blue Spray Indicator Dye (I did 1 once per my tank) to know where I sprayed. These measurements cover 1000 sq feet which is 1 gallon in the sprayer but I then adjusted these measurements for a 4 gallon tank (Chapin Tree/Turf Pro 4 Gallon BackPack Sprayer) . I applied when temps were under 85 degrees and made sure no rain or automated sprinklers would interfere with its effectiveness. I actually kept any water off of the grass for a week to make sure it had ample time to absorb. What I observed was that weeds after 7 days started turning white, that lasted another 5-7 days, then by the 3rd week most weeds had wilted and died. The one weed that tenacity did not effect was spotted spurge but should have paid closer attention to label as that is not a weed it covers. I gave tenacity 4 out of 5 stars since it doesn't kill all weeds -does not kill spotted spurge which means I have to supplement this with another chemical.

Tenacity worked great. All of my crabgrass is turning white. Obviously I used it as a post emergent. I am looking forward to next spring to apply as a pre emergent. (I used the surfactant product along with it as recommended for post emergent applications so I would definitely get this as well)

I used Tenacity to remove bent grass from the backyard and some spots in the front yard. It worked great, the grass turned white and now it's dying.

Well we eagerly looked forward to using this product, and looked forward to results, and 14 days later still looking forward. Sorry a Spray of Dawn might do more. Wasted coins.

Bought this to kill my crabgrass. Had it bad this year. First application turned it white as it died, but was so bad that I needed another application. It does work but your lawn will be white where ever the dying crabgrass it. Worth 2 weeks of white lawn. it does work, If you need to kill crabgrass it does work.
