Negate 37WG Herbicide

I applied Negate to my Bermuda grass front yard two times last Fall. One in September & I application in November. I meant to do another application in January 2025 but the weather wasn’t good. My lawn looks great this Spring. I get compliments from my neighbors who have lawn service. I had a ton of POA annua. I still have a little bit but I would say 85% less from last year. This really works!! I will be doing more applications this Fall again as several of my neighbors have a ton of POA Annua so I’m exposed from their lawns.

Negate is expensive, but the 1.5 oz bottle covers 1 acre. Refer to attached photo (taken on March 21 in North Alabama). Wear long pants, boots, a K95 mask, gloves, and eye protection. Negate is a dry powder, made of two herbicides. I shook the Negate bottle well before opening it. I filled a 1-pint plastic bottle half-full with warm water and added 1/2 teaspoon of Negate; shake mixture for a full 5 minutes. Next, half-fill a 2-gallon sprayer bottle with warm water. Add Negate mixture and mix well. Add warm water to fill tank to the 2-gallon mark. Add 0.64 ounce Southern Ag Nonionic Surfactant and 2 ounces of Lazer Blue Dye. Mix well. The 2-gallon sprayer bottle will cover 2000 square feet. Spray grass in rows in one motion. Do not cover any area of grass more than once. In 3 or 4 days, you will start seeing results. The attached picture was taken 7 to 10 days after the application. You can see streaks of poa annua in the yard that I missed. Negate works and does not harm Zoysia or bermuda. The area next to the sidewalk is Zorro Zoysia. The area next to the driveway is mostly bermuda.

This works well to treat resistance in my weeds to previous herbicides. However, you do have to remember to mix the entire contents into a separate container first to figure out the concentrations.

I was skeptical. I was desperate. Poa laughed at my Barricade applications for the past few years.This year, nearly 1/3rd of my TifGrand Bermuda lawn was green - but from Poa Annua.I'm a regular homeowner, with an interest in having a nice lawn (unlike my neighbors), but I had to get rid of this Poa in the same way that Bill Murray had to get rid of that gopher in the Caddy Shack movie.Working with a high-powered product such as Negate made me worried about chemicals and chemical exposure. I really couldn't tell how to use this stuff, but I read a lot online. Here's what I did:Purchased this Negate. Purchased a mask (plenty of those around now), wore pvc gloves and eye protection. Also purchased a 2 Gal Dewalt brand garden sprayer from the orange box store (I used the red,medium spray tip).From an empty 1 gal. plastic milk jug, I poured the entire bottle of powdered Negate into this milk jug. I then, filled the jug up with water, maybe 3/4 full. Put the cap on the jug, thumb on the cap and shook vigorously for a few minutes. I really don't know the whole precise way of doing it, but anway. . . Next, I took a 16 oz Dsani water bottle, drank the water, then cut it in half. With a graduated cylinder as a reference measure, I poured 3 oz of water into this cut-in-half water bottle and marked a line on the water bottle with a sharpie and disgarded the water. I shook the milk jug with Negate mixture in it, again, then carefully poured 3 oz into this half water bottle. I poured the 3 oz of mixture into the garden sprayer, then filled the sprayer with 1 gal of water.I sprayed my infested area all over, not just a spot treatment, but all over the area, maybe 1,000 sq feet, at the most.After one week, I really did not see any change in the Poa. I took the milk jug with the Negate mixture that I prepared on the previous week and shook it again, and, this time, went up to a guess of about 4 ounces of Negate, then poured it into the sprayer, added a gallon of water and tried again over the same area. Five days later, I saw strong signs of my Poa Annua dying. I really wanted to see ressults in days, but it took a while.Finally, I mowed my lawn and the Poa is not coming back! Success! Yes, the temps were warming up and that kills Poa, too, but this knocked it out. My Poa is on the cool, shady, wet side of my house, but it's gone! The best part is that I did not see any evidence of damage to my TifGrand Bermuda and the Poa is not coming back.Overall, I will buy again, next year, if needed.I probably used too much of this product, in other words, it probably needed to be diluted a bit more, but hey, it worked!I took the left over Negate mixture to share with a friend who also had a Poa problem because of our cool, wet Spring.Sorry, I wish I had some before and after photos.

I was not able to spray pre-emergent this past year and had a serious poa annua problem this spring. The pictures are from 2/15, 3/15, and 4/15 and in North Texas. I sprayed an initial application on 2/15. The good news is this stuff kills poa. The bad news is my zoysia is suffering. My grass is now pretty thin in probably about 50% of my yard. I am hopeful that it will come back in the next couple of months but I did follow the mixture directions pretty carefully.I mixed half the product in a 2-liter bottle and then made 4 separate applications with a 4-gallon backpack to cover 1/2 acre. I then mixed the remaining product into another 4, 4-gallon applications and treated another 1/2 acre. Not sure if I would use again - that would depend upon what my yard looks like in June/July... If it comes back, I might up the 3-stars to something higher. The label said nothing about zoysia, but it is a warm season grass so I went for it.===5/30 Update: My zoysia is doing great. I'm fighting some spurge now that wasn't showing before, but Negate is a post-emergent and really worked well for me. Definitely recommend.

I have struggled with the spring time poa annua flair up in my central Alabama lawn for years. After reading other reviews I decided to give this product a try. I mixed the entire content with a gallon of water. I then used 3 ounces per gallon of water in a 4 gallon backpack sprayer. After about two weeks I have seen significant change. The Poa annua is turning yellow and dying. My Bermuda seems to be growing perfectly fine in the treated areas. I understand the shelf life for this product isn’t great I’m not sure about that but I will have no problem buying another bottle next year.
