Customer Reviews for Certainty Herbicide - 1.25 oz.

Another product, like Metsulfuron, that I use to remove cool season grasses from Bermuda, but which also works on sedges, and is similarly slow like Metsulfuron. Wait a week or two in spring and the poa will die off. Together with AmTide in the same bottle with surfactant, you can eradicate fescue and poa. When mixed with MSMA later in summer, it will really knock out dallisgrass, though you could just get rid of dallis with only MSMA. It comes with a little measuring spoon in the box to help you get the right amount per gallon of water.

I applied Certainty Herbicide to eliminate nutsedge from my lawn. It has been over two weeks since I sprayed. The weed has stopped growing. The leaves show some yellowing. Now I am waiting for the KILL!

Bought this to take care of some of the cool season grasses invading my bermuda lawn along with a ton of yellow nutsedge. I did two applications mid summer at the minimum rate (probably could've done one at high rate) and after the second, the rye grass, fescue and yellow nutsedge were immediately fried. Mission complete. Highly recommend. May need two applications fyi.

It works as advertised! I applied using a pump sprayer. Followed the the directions for application and a week later weeds are dieing! Delivery was on time! Thanks do my own!

Certainty helped clear up a massive infestation of Yellow Sedge in my Bermudagrass. The surfactant obviously helped with penetration. However, I didn't find the blue indicator dye particularly useful in my residential application because I couldn't see it (medium concentration) and it makes a mess.
