Finally found something that kills poa annua (annual bluegrass). Most of the other products that kill this stuff are outrageously expensive, and I was not going to pay that.

This did not look like it was doing anything, and then two weeks later, it was all brown and dead. This is unlike any other herbicide I have ever used, and you have to go on the internet to find out how to mix it for a gallon sprayer. You have to mix the entire bottle at one time in a gallon of water, and then use three ounces of that per gallon in a sprayer for spot treatments. It is only good for 2-4 weeks after being mixed.

I will be more diligent in putting out the pre-emergent next fall, but I will not hesitate to get more of the Negate 37WG if necessary.

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.

This really worked. But of course timing was a major factor in this. I used it when ground temperatures would just be low 55°. This had made a significant difference in the amount of weeds I have today. I will use it again in the fall to keep winter weeds out of my Bermuda

Year 1 of purchasing home I used over the shelf weed killers. Made the situation worse. Year 2 I used multiple over the shelf weed killers and some weeds died but POA became stronger. Year 3 I used Image weed killer for warm and cold weeds and it worked a little better than year 2 products but POA became even stronger and I felt like giving up. Year 4 (5 weeks ago) I sprayed Negate 37WG at 1oz/gallon and I can't find a weed in my yard. Only Bermuda grass is emerging. I'm happy amd ordering more of this stuff for the fall. Just buy this product you won't regret it.

Great herbicide for listed weeds. Works well on Poa Annua and many others.
