Works Quickly to Kill Sedge Not Lawn

Worked faster than I thought. I applied it to the yellow nutsedge in the lawn and thought it would take 2 to 3 weeks to work, but the sedge started to die and brown up within 2 days. I will watch it to determine if it needs another application. There was too much to pull out manually and this made me try this herbicide.

Worth the research and money

For 3 yrs now my neighbor and i have had this weed in our lawns. My lawn is like a golf course and i would always pull this weed out manually. After doing research on Nut Grass and seeing whats available to use i came across this product by Ortho. After reading the reviews of this product i tried it this month. In just 2 days the nut grass turned yellow and is dying out. I wish you could get this product in a larger bottle say 64 ozs. so you could use a pump sprayer to cover your entire lawn. I would highly recommend this product to any one, it works great.

Mature nutsedge turning brown in less than 2 days

I am quite satisfied so far. After 3+ years of infestation and pulling and digging to get rid of the sedge I am starting to see results. I mowed 2 days ago, then we had a day of showers (I thought this might help the grass from being damaged), so I sprayed this directly onto my nutsedgey lawn to test/ spot treat the nutsedge. The sedge is already golden-brown and dying while my bluegrass/fescue is still thriving. No damage even though I sprayed on a warm morning, the sunny high reached 88 degrees, and it is late in the season (early August). They say it is better to spray in early spring. I hope I don't have to do another round of treatment like most folks review this product, but I expect I will have to since it is so late in the season and we've been infested for years. If spraying again means a future of no sedgy lawn, I am hooked and it is worth it. Could have been a bit cheaper, come in a larger bottle, or even a trigger that I don't have to manually spray over and over again (my wrist hurts and I only sprayed a small section 2 feet by 10 feet).
