So far, looks good
By Rhoda on 10/15/2020
I was skeptical because after applying it last month, I saw no change in the wild violets that I'm trying to get rid of. I don't understand mixing ratios so it was probably my fault. I bought more because the wild violets are taking over my bermuda grass. I carefully mixed it this time and applied it with the garden sprayer. The first time I used the garden hose and a spray bottle. I used triple the amount of blue color because I didn't want miss any spots. After spraying, I did not water the grass as I did the last time. A few days later it rained. That was last week. I've been walking the yard everyday since then. The wild violets are bent over but I'm not sure if that means they are dead. I really have to wait until Spring to see if any of this is working. I was expecting the grass to be stressed but don't see any evidence of it, like the first time when it turned brown. So, the wait begins. I gave it 5 stars because it get rid of the weed that looks like a mimosa plant and the one that looks like a head of lettuce.

Works well
By Chris on 09/18/2020
Followed the directions and slowed the growth of the weeds might put down another treatment with same amount. Grass didn't yellow after first application so if they dont go away I will put down an extra oz of this solution...

WOW -- August 2020
By Mdb on 09/03/2020
August 2020. We purchased this because the yard was full of all types of weeds. Lots of Crabgrass, Clover, Nutsedge and Oxalis and whatever else I couldn't really identify. We did not use any pre-emergent this year at all and because of so much heat and rain the weeds just kept coming till the entire yard was almost completely covered. We purchased and sprayed Q4 product in when we could find a dry window. It worked wonders. It was a killer and worked fast. We would definitely purchase and use this product again. We plan to reseed early September because the label reads for TTF you can reseed in 7 days.

Onion Grass Terminator
By Michael on 04/15/2022
I talk to a representative of DMO about my abundant onion grass throughout yard. She recommended Q4 Plus Turf Herbicide. A week after application the results were amazing. Highly recommend this product. Only regret, should have bought a gallon.

Worked for me
By Aaron on 02/02/2020
I had a bad infestation of barnyard grass in my Bermuda. This product works on the barnyard grass. Here's the thing. It doesn't really tell you how much to spray in the manual so I had a hard time knowing if I should saturate the weeds or lightly spray. So I did an experiment. On half of the yard I spot sprayed mildy. I wouldn't say I soaked the weed but I made sure it was wet. On the other half I very quickly and lightly did a misting blanket spray. Here's what I observed. On the side where I sprayed heavier I had a bunch of browning Bermuda. It even killed a bit of the Bermuda unfortunately. On the side I blanket sprayed (misted) I had only a little yellowing (and it might have just been the barnyard grass dying) but it worked very very well! I was surprised how little I had to spray to wipe out the barnyard grass and it worked very well doing so. So, now I know for this summer. It doesn't take much to kill barnyard grass. Spray lightly.

Excellent stuff
By Ken on 06/23/2023
Used this a week ago and already killed off thistle and crab grass that inundated my Bermuda grass. Used 2oz per gallon of H2O and worked AWESOME! Did not cut grass 2 days prior and waited 24 hours to water after treatment. 5 star product for my problems with lawn.

Q4 Plus Turf Herbicide review
By Jeff on 08/08/2023
Q4 Plus works great. I had various weeds, dandelions, purslane, yellow nutsedge, and clover on a couple of my properties. After using Q4, the weeds were dying within a few days. I use this stuff 2 times a season and fertilize with PGF complete and have the best yard around.

Weeds
By Danlb on 09/01/2015
Excellent product. I live in an HOA where the landscape company isn't familiar with weed control so I get all my neighbors weeds. I am a little bit of a nice lawn snob and despise weeds in my lawn. Now I can concentrate on aerifying and overseeding before winter.

Great product
By Adam on 04/23/2017
This product was recommended by a lawn care professional that I know and i am glad he told me to buy it. This product is superior to anything you buy at a lowes or Home Depot. One word of advice is follow the instructions for mixing and application and above all be patient. You will notice your weeds start to whilt in a few days and then completely be gone. Shipping was quick and I am very happy with this company where I purchased this product and will be buying more products.

It worked very well
By Chuck on 11/15/2024
I hadn't identified what weeds I had in my lawn so I tried this produce to see if I could have success. It did a great job on clearing the weeds. It worked pretty well on the nutsedge weeds also. I used my 2 gal sprayer and hit each weed, took a bit longer but seemed to get the job done.
