There was a problem filtering reviews right now. Please try again later.
It does take time to work, I applied it in January just before the frost started here in Texas and the vegetation was still green. It took about 3 weeks to completely kill everything it touched, but there were visible dead patches forming after about four days.
It was even powerful enough to kill this bush that's been growing up from under my foundation for years. Even if I cut it down, it always seems to grow back. Not this time.
There is also a large open field that borders my fence line. They cut the grass, but they never cut near the fence, so I end up with this wild mess of weeds, tall grass and thorns that grow over and into the fence. I sprayed this directly on the tall grass and it's all dead.
The main reason I bought this was because half of my lawn in the back was overgrown with weed grass. So in a weeks time, half of the yard would look fine, but the other half would already be 4-5" tall with thick grass. I needed to cover a large area, and I didn't want to spend $60 at the hardware store on pre mixed bottles. This worked great. It's been two months and the only thing that has grown back is a few patches of "clover." You can see in the photo the half I sprayed vs the half I didn't.

So far I am having mixed results. After my first attempt I used 2 ounces per gallon of water in a 2 gallon sprayer.
I don't have a huge area to spray, just mostly the annoying weeds that pop up in my gravel drive.
It took about 4 days before I started to see results, and this was under very warm and sunny days. Even after a week some of the weeds are still hanging around so I doused them again.
So far the weeds that did die off have not come back but I kind of feel like I had to really soak them good to get them to die off.
I'm not 100% sure about this product yet and will know more as time goes on this summer.
The weeds in these 3 pictures were all sprayed at the same time and close to the same area, as you can see they are not very big weeds and 1 has died completely, 1 looks to be dying but the other one still looks green. This is after 1 week.
So far it's Ok.

I noticed comments about “ it killing everything”, AGAIN READ THE INFORMATION…it’s a KILLER. It WILL kill anything u put it on, so don’t spray it when it’s any kind of wind or breeze if possible. U also HAVE TO PAY ATTENTION, hold your spray wand close to what u r trying to spray to help avoid what u do not want to kill!! Leaving a bad review because of NOTHING the product did/didn’t do, but because of buyer negligence to READ/FOLLOW instructions is beyond irresponsible and irritating.
This product is a SLOW kill. 6 days and just now it's starting to turn the grass and weeds a light yellow. I needed something much faster. But I purchased this product because you can till and replant. But untill see the grass and weed are truly dead before I till them under.
The product seems to work, but these kind of products take time.
