Customer Reviews for Tenacity Herbicide

Mallard was infested with crab grass. Three days after I applied the product I started to notice all the crabgrass turn white. Buy one week everything was dead aside from my grass. Got a nice built in pre emergent too!

Do My Own had the best price and delivered the product in a quick time and as expected. Couldn't ask for more. After one application a lot of Bentgrass is dying out and a few other stubborn weeds. Two more applications should have me set.

used as directed post emergent with a surficant ( dawn dish soap ) 3-5 days most crabgrass was white or turning, going to mow, wait 2 days then apply 2nd application. My yard has never looked so good. DO NOT USE THE SYRINGE THAT COMES WITH IT ( mine was junk / sticks / hard to use ). I wanted to knock 1 star for the syringe but the product itself did exactly as claimed.

I have read some of the negative reviews, and it makes me wonder if they are mixing incorrectly, applying incorrectly, or using expired product. Our lawn (perennial rye) developed significant crabgrass patches. Sprayed with Tenacity mixed with a NIS, and in just under 7 days, crabgrass went white as expected. Awaiting second application, and looking forward to hopefully a crabgrass free lawn next spring. BTW, we had broadcast a dry pro-brand pre emergent, but apparently too late.

It took a few days to kick in but after a week crab grass is starting to die. It also looks like it took care the nutsedge grass too. An added bonus.

Fast easy reliable service. The verdict is still out on the effectiveness of Tenacity. One week since spraying dandelions in my lawn not quite sure of results. Have tried other products that killed them quicker but also got the lawn as well.

Worked great within 2-3 days I could see my crabgrass had turned white and died off. Works better than any store bought herbicide I have used.

Had no idea that my lawn is full of weeds until recently i started looking up lawn care and came across Tenacity. One application is all worked for my lawn, 80% of the lawn turned white in 5 days and all weeds gone in 9 days.

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.

Works really well kills crab grass and vaporizes it to a dead white like it's supposed to do. No more photosynthesis so weeds turn white. Much better than OTC weed killers.

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)

First I was thought I made mistake to buy this product. After 2 weeks it shows magic result, can't even believe it kills from the root. I had very nasty weed the backyard now everything is gone. Even save lots of money. I suggest use surfcant with this product to see the better result.

After planting a bag of Scotts ever grow grass seed my lawn grew an abundance or weeds including crabgrass. I applied Tenacity according to the directions. I applied a second mixture ten days later. My grass is now being allowed to grow and the crabgrass and other weeds are dead and all brown. This stuff is amazing.

I have wrestled with crabgrass in my yard for the eight years we've been here. This product wiped it out... mid summer with it establish and growing again. The bluegrass in invades every year was untouched. I can't wait to see the result next year as a PRE-emergent.

When it comes to controlling established crabgrass, this is the only product I have found in 37 years of lawn maintenance that does the job right out of the gate. No damage to existing turf when used as directed.

Been trying to get rid of yellow nutsedge out of my yard for years and I think I got it with Tenacity. I had tried many other herbicides and could not get rid of the nutsedge. I Highly recommend Tenacity. It will turn the nutsedge and any crabgrass white and it can look kind of bad during the killing phase but did not hurt my fescue grass.

I tried tenacity to see if it would kill my nutsedge. It worked! Very happy

I'm always skeptical about a new chemical, but Tenacity worked exactly as it claimed. Use it lightly and consider mixing in TurfMark so you can see it go down. It kills crabgrass in a few days without harming centipeed grass. I spot sprayed and 3 days later you could see the crabgrass starting to die.

Despite treating in spring with the blue fertilizer, I had a lot of crabgrass in my yard. I was hesitatnt to treat because of the heat, biut it was getting out of control. So I used for Tenacity for the first time with good results. At this time the crabgrass is all white, dying and the lawn is not affected.

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.

This is the active ingredient to the three part ingredient recipe. It appears to be working, the crab grass turned blue immediately after spraying and then white after about a week after application and now appears to be turning brown and hopefully dying.

Did not expect any results. Be patient. Then check out the tips on quackgrass! Yep. Live in Indiana and it worked. Was going for nutsedge and poa annua, may need a couple more rounds.

Did a great job on my yard with crabgrass and clover. I will do a second application. The syringe worked very well to get an accurate amount per gallon.

I maintain about a half acre of turf and this was very effective on my young as well as established crabgrass. I used it with a nonionic surfactant as recommended to get it to adhere to the crabgrass. Within one week there were visible signs that it was working and a week or so later the vast majority was nearly killed off. Two weeks later, I touched up some areas that I had missed and some areas of well established weeds that weren't totally dying off yet.

So I was an idiot and didn't put down weed killer earlier this spring/early summer because I was afraid of burn spots and I had crap grass ALL over my lawn. I tried a cheap version of crab grass killer and it failed but had to wait a week or so to really see that it didn't kill anything. At this point I wasn't looking to play around and need to spend top $$ on the best stuff on the market and that's this stuff, Tenacity! I used my own 2 gallon pump sprayer, Surfactant, and a blue dye on my roughly 4000 sq ft yard and I could not be happier with the results! It took about a week to start to see the crab grass weeds only start to turn white and I did another application about 2 weeks later like they recommend. It is now a month later and their is not a single crab grass plant in my yard!!!!! Some of the grass was bleached but after another week of mowing ill cut those grass blades tips off from growth and my lawn will be perfect. In conclusion, buy this stuff and just fork over the extra cash for it. It is worth every penny to not see all the different annoying weeds in your yard. I plan on putting down seed this weekend to over seed and I wont have to worry about it preventing seed from growing which all other products say you cant do. I am going to recommend this to anyone out their moving forward!

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.

Super easy ordering process, product arrived on time. I studied and reviewed Tenacity online from multiple reviewers and it has worked as claimed. Note before purchasing: know your grass type and understand what this product will and will not do. Great product and highly recommended.
