MCPP, 2, 4-D and 2, and 4-DP on centipede?

Hey i have dandelions in my yard and a friend of mine gave me a bottle of triple threat by complete solution. It specifies not to use it on dichondria, st. augustine, and something else. I didn't see anything on the label about centipede. The active ingredients are MCPP, 2, 4-D and 2, and 4-DP. I was thinking that it couldn't be sprayed on my yard since centipede and st. augustine are tit for tat on tolerability. Let me know...

The one and only time I used a conventional Three Way amine on centipede, I remember it stunting, burning and yellowing the centipede. It also failed to completely kill the weeds I intended to kill. 2,4-DP, and MCPP are probably the worst things to apply to centipede. My broadleaf mix of choice for centipede or st augustine is metsulfuron + Quicksilver. It hurts the weeds way more than the centipede.

Hey: That centipede will die if you even get the bottle close to it...St. Augustine is far more tolerant with some chemicals than centipede. Do Not Use it!

You simply cannot use any type of 2,4-D compound on Centipede.
Atrazine may control some of the tap roots like Oxallis and Allum spp. present, and I am certain there are other herbicides available.

Thanks that is what i was thinking and then......... Low and Behold on the LABEL it reads...

NEWLY SEEDED LAWNS may be treated after they have been mowed at least
3 times. BENT, RED FESCUE, CENTIPEDE AND CARPET GRASSES: Use onehalf
the recommended rate (2 teaspoons of product per gallon of water covers
200 sq. ft.). Make 2 applications 10 days apart. Do not apply to Dichondra,
Lippia, St. Augustine and Clover lawns.

Confusing but i am with you all on this chemical.. Like i said a friend of mine gave it to me because the minimum order was four 1 gallon containers. He used it on his zoysia which automatically made me think it wasn't going to work.

hey fella's I have applied illegal amounts of 2 4 D on my centipede trying to kill a specific weed. I mean gallons per acre and the centipede walked thru it like is was just being watered. Iwas to the point I didn't care if I killed the grass as long as i killed the weed. Well, it killed neither. I would not recommended this action nor would I try this on a customers lawn. I always apply 2 4 D for broadleaf weed control along with "poast" for grass weed control. And 2 4 D will kill fescue (St, Augustine) at the drop of a hat.
