It works
Product works well on crab grass, it is slow activating 2-3 weeks but it killed the stubborn crabgrass and it did not affect the St. Augustine

Works Wonders on Weedy Bermuda Grass
I am in the south and bought a house with Bermuda. Unfortunately my back yard was more weeds than Bermuda. This was my first step in killing the weeds and having my Bermuda expand. I will definitely be using this again to work on my front yard in the spring if my pre emergent doesn't get everything. I would recommend. Don't be shocked by the small package

Great product!
This herbicide was just what I was looking for - something that would kill the weeds, but not my Saint Augustine grass! Especially in the summer when it’s difficult to kill the weeds, but not the grass, this product did just what I wanted. After two or three weeks, I see that the product is working; the weights are tying or dead, and the grass is thriving!

Works as intended
I used this to take care of some different types of weeds that were in my lawn that consists of Bermuda and st augustine. It said it was safe to use the type of grass and it didn’t hurt it at all. It was easy to use. When I applied it I didn’t notice a difference the first few days, but then probably after about a week the weeds started to shows signs of wilting and drying out. Then after 2 weeks I could tell that most of the weeds were mostly brown compared to the green grass. I did notice some weeds were still alive but I probably missed them the first time I sprayed but that’s on me. I would recommend spraying another time maybe after to 2-3 weeks to ensure that the weeds are killed. This product is really good at what is does it killed weeds that I didn’t know were there. Overall I recommend this product if you have weeds in your lawn.

Seems to work (slowly), surfactant recommended
Seems to work (slowly) on Dallisgrass, I'll update this review if it doesn't. I mixed the powder w/ water at the highest/strongest ratio recommended in the instructions. Something I noticed is that the solution seems to bead up on the plant. This doesn't seem ideal. I'd recommend mixing this powder w/ a surfactant meant for mixing w/ herbicides.
