Syringe Failure
By Pete on 04/30/2019
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.

Tenacity for Chickweed
By Skip on 09/09/2014
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.

Good product

So far so good
By Eric on 09/09/2022
Easy to mix, the directions on the bottles are pretty clear. The dye washes off with water so don't be alarmed if you get it everywhere. At first I didn't think it was going to work but after about a week all my crabgrass turned white, so be patient. Overall I satisfied with the results.

Tenacity works
By James on 09/01/2016
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.

Clover, crabgrass and dandelions
By Jeffery on 03/18/2022
As with most folks, I was expecting to spray one day and see dead weeds the next day. Well, it didn't work quite that fast but within 2 weeks all of the clover was dying. I haven't looked for or seen any crabgrass and there are still some dandelions here and there. I will apply again when its time. There is enough left for at least one more application. Clover was my biggest problem, and that problem has been handled. If the second application gets rid of my other problems than this product deserves 5 stars.
two weeks
By Tom on 05/06/2022
Well I'm not sure if how good it really is. I applied it once two weeks ago and am just now seeing some results but very slightly. It wasn't supposed to rain the next day after applying to lawn. But it did. And it keeps on raining. Am going apply second treatment as soon as I can get a break from the rain.
Works, but takes a long time

Tenacity first application
By Bob on 09/02/2022
This is my first time using Tenacity. The primary reason is to kill the Creeping Charlie that has started invading my lawn. I made a 2 gallon batch according to instructions. Tenacity 1 tsp., dye 1 tsp., and surfactant 3 tsp. . After watching several you tube videos, I was careful to not over apply. After 1 week the grassy areas have turned white, but the Creeping Charlie is barely affected. I am prepared to make additional applications according to need. I am aware this could take a couple of months so I am not disappointed at this time. Bob S.
It works
By Richard on 03/19/2021
I found Tenacity to be effective against Nimblewill in St.Augustine lawns. Follow directions carefully. Repeat as directed and you should see a positive outcome. Before use, understand how Tenacity works and what to expect.

Great Product
By Dawn on 03/25/2023
Love Tenacity but 1st time buying from this company. Wish you would include instructions on how to use the bottles. Appears they have premeasured areas, but couldn't figure out how to make them work. As expected, all the weeds in my yard started dying within a week. Will reapply within the recommended 2-3 week timeframe so should have a beautiful lawn by mid spring. Definitely recommend Tenacity!! 4stars because of the bottles, not the product.
Purchased again
By Marcia on 08/27/2023
The kit works fine for a small job. Through reading reviews I found out what my 3 main problems are, bentgrass, nimblewell and crabgrass. I literally had to spray my entire 7,000 square foot yard with a 2 gallon sprayer. Just completed my second application. Planning to do a third application in another 2 weeks then power rake the dead areas and aerate the entire yard before overseeding the yard. First off this is not a fast acting herbicide. After 2 weeks I see it killing more nimble weed and crab grass than the bent grass. It's set back but not dead yet. I wish I would have started 2 weeks earlier, but hopefully in another 2 weeks I see a good kill.

Pros and cons
By Michelle on 09/15/2023
Excellent product. Used it for the first time this year and my yard looked amazing. Getting the product in a timely manner was frustrating. Twice had a failed delivery due to damage caused leakage. Company blamed shipper. Shipper blamed company. I really don't care who was at fault. Just package it well enough that it gets to the customer the first time.

Results aren't immediate, but effective
By Sandi on 10/06/2023
Together with the High Yield Sticker solution, Tenacity herbicide very effectively killed crab grass with one application. It wasn't immediate, 3 days after application, I wondered if it would work. One wk after application it was very evident, the crabgrass was dieing. The quackgrass however is requiring a 2nd application and maybe even a third in the spring. But no worries there is plenty product in both bottles. Did it spare the grass ? I can't tell, because the quackgrass choked pretty much all of that out.
Crabgrass turned yellow and dying
By Debbie on 04/05/2024
Hey. I sprayed the combo of stuff on a side yard that had crab grass, dormant Bermuda, and fescue. It took over a week to notice any changes....long enough to think it didn't work. But then I started to see a yellowing of some of the blades. That has continued. Now I am seeing a few of the yellow blades turn white. I'm waiting for the whole cycle to complete before I spray the whole front yard. Sadly I purchased fescue seed contaminated with the crabgrass so my once beautiful lawn is going to look terrible for a while. But thank to this product I don't have to pull up the crabgrass.
Seems to be working
By Vincent on 08/16/2019
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 Attack
By Mark on 08/09/2019
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.

Effective weed tretment
By Ken on 05/15/2020
Almost perfect
By Aaron on 05/28/2020
Did two applications per instructions with NIS 2.5 weeks apart. So far the dandelions are nearly gone and the chickweed is really stunted. Unfortunately only the very young clover has died off and even more clover has grown in the last 3 weeks. Any advise would help here.

Happy lawn
By James on 03/20/2020
Mixed the three solutions sprayed on lawn as per instructions and it took about a week to activate and suddenly all the clover crab grass and dandelion's started turning white. Good bye nasty weeds! This is a great find my neighbors will all be ordering soon thank you again. I have tried many other chemicals to get ride of clover nothing worked I would never use the nasty toxic stuff from Monsanto, this is the safest solution I could find.
