Used product on stubborn grass in flower beds. Required over a week to see results. Applied second application and growth of grass has been retarded and grass leaves are turning yellow. I assume the grass is dying, so I am pleased. Beats having to pull the grass. No adverse affect on Iris, Daylillies, and other flowers in the garden. I used the Hi-Yield sticker in conjunction with this product, as recommended by manufacturer.

It seems to be killing burmuda grass but also harming my St. Augustine so I have been springing with sprigs from edging lawn. There should be a product that kills wild Burmuda grass without harming your lawn. Vantage used to be such a product and it killed Bahia grass also. Let me know when you get such a product.

As Vantage (which contained 13% sethoxydim) is no longer available I bought this product to kill carpetgrass in my centipede lawn. The High Yield post-emergent herbicide (HYPEH) did not list carpetgrass to be selectively controlled as it was listed on the Vantage label. I treated the weed during a drought so was not sure the product would be effective. After 2 weeks (and Hurricane Dorian's 7 to 8 inches of rain) the carpetgrass is yellowing and some appears to be dead. As with Vantage I may high to re-treat the carpetgrass. HYPEH is supposed to control bermudagrass but the effect not apparent yet. I used the H-Y Spreader Sticker with the HYPEH. Hoping HYPEH will kill all of the carpetgrass and bermudagrass. I have not observed effect on Bahia grass (because I have not looked) but it should also be killed as Vantage did kill it.

I had some Bermuda grass growing in the centipede grass, this stuff killed the Bermuda grass without fully killing the centipede grass. The centipede did yellow a little bit and was stunted, but was not killed.
