Review: Pleased - Definitely my favorite weed killer! I grew a patch of sunflowers this year and Bermuda grass took over along with many different weed types. Got this, problem gone. Did take a little while before I saw results but once it did, everything was gone! It took no time to mix it up and spray it on. Be cautious not to spray your ornamentals because they will die! It’s strong, kills everything it touches.

### ⭐ Does not kill lawn grass/fescue
*by L***B on May 21, 2024*

I thought I was buying the equivalent of Ortho Grass-B-Gone which works great, at least for a time. But Ortho does not come in a concentrate which I wanted for re-application til the grass died permanently. Only when I looked at the fine print, did it mention killing quack grass and crabgrass, yet lawn grass, e.g., fescue and bluegrass are missing from the list. In certain areas of my garden beds I have a lot of lawn grass popping through the ground cover and at the base of perennials. So the grass can't be handpicked. This product did not work at all for my purpose. A $42 waste of money and time spraying on 2 different occasions.
