## Description

Quali-Pro Negate 37WG Herbicide

Review: WORKED INCREDIBLY WELL. - Quali-Pro Negate 37WG did an outstanding job controlling Poa annua in my lawn. I only mixed a small amount to use for each application. After applying, the Poa annua began yellowing within a couple of days. After a week, most of the poa anua have already died off. Some were able to survive so a second application was needed. After the second application, all poa anua completed died off. It did not damage my bermuda grass at all. This is one of the most effective products I've found for stubborn Poa annua, and I'd definitely buy it again.
Review: Verified Purchase - Victory over Poa Annua infestation this year! TifGrand Bermuda - 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.

## Questions & Answers

**Q: What is a recommended sprayer for this product?**
A: Hand pump sprayer or back pack sprayer. Negate is a very potent product and generally is used in large tanks such as 50-100 gallon tanks. Finding the correct measurement for a hand pump sprayer or back pack sprayer is difficult but not impossible.
For smaller applications, where accurately dosing small quantities of the Negate granules, I create and store an intermediate solution with 1 TBSP of Negate granules to 14 ounces of water. This solution can then be used at 1 ounce per gallon for 1000 sq. So you will be diluting it twice!

Thank You

**Q: Will this damage/kill Kentucky blue grass or perennial rye grass?**
A: Negate 37WG should not be applied to Kentucky Bluegrass turf. Negate 37WG is only labeled for application to warm season bermudagrass and zoyiagrass when used on residential lawns.

**Q: After applying this to my lawn that's full of poa annua, how long should I wait to cut my grass?**
A: Each herbicide may be different, but 99% of the herbicides I use tell you not to mow the grass for at least two days prior and two days after the application.  And obviously you don't want to apply when rain is in the forecast.  You may want to mix with or do a different application of a pre-emergent such as prodiamine or dithiopyr.  If you're using Dithiopyr as a post-emergent, I believe you need to apply it as a spray for foliar absorption.  If you put it down as granules, it doesn't have the post-emergent effect from what I've heard.  These pre-emergents will help prevent any new or existing seeds from successfully germinating and allow your warm season turf to spread and fill in the area without competition.  1 TSP would be all I need for my lawn, and that' still overkill.  1 TSP would give me enough to treat my lawn several times.

**Q: Can I over-seed bermudagrass after I use Negate?**
A: According to the label, you can overseed 28 days after applying Negate 37WG.

Thank You

### ⭐⭐⭐⭐ Negate 37 WD Herbicide
*by M***M on April 12, 2024*

Used Negate 37 WD Herbicide on annual bluegrass in a hybrid Bermuda lawn. Two applications 2 weeks apart were needed in the areas where the annual bluegrass was thickest. One application was needed in other areas. The only thing I don’t like is that you have to mix the entire container at one time, and unless you have a large area to spray you end up with some leftover herbicide after four weeks. Tried two applications of Image for Nutsedge prior to this. This only killed some of the annual bluegrass. Applied the first application of Negate 37 WD March 19, 2024 and the second application two weeks later. We had no rain for 3 days after the first application, and no rain for 2 days after the second application. There is no evidence of any damage to the hybrid Bermuda grass. Would recommend this product.
