I tried for a couple years to eradicate Bermuda grass (weed in Florida) with Roundup Pro and other similar products with no success. While I always got a top kill, it always came back. Then I found this product. I actually bought it to tree saplings along a fence line. While spraying the fence line, I inadvertently sprayed a small patch of the Bermudas Grass. A few days later the Bermuda began to yellow, and within a week or two it melted away. I then used it to treat all the other Bermuda – a 100% kill rate. In a couple of areas, I did have to treat a second time. It’s now been two years and still no sign of any Bermuda. I did spot treat a couple areas in my St Augustine grass with great results. But be aware, this will kill almost everything it comes in contact with so use with caution. If you plan to re-sod, I found it best to wait a couple months because nothing will grow where this was applied. By the way, it worked good on the saplings too.
