@LAlawnnut I have centipede and use Atrazine. I got a gallon off Amazon for around $30. It's for St. Aug and Centipede lawns. It's worked well so far.

 

MSM and a 3 way like Speedzone Southern

 

I've heard that if you look at it wrong, some centipede lawns just die... but then again, that might be St. Aug. /s

 

I sprayed MSM on my centipede early feb and it took it well.

 

I'd go with some Atrazine. I did some a little over a month ago and it got rid of a ton of weeds. I knocked out the rest with 2,4D, Mecoprop-p, Dicamba and Dithiopyr (Spectracide weed stop for lawns w/ crabgrass preventer) There's a Pre-Em in that product too for the crabgrass that'll show up later in the season. I've also heard that Atrazine can be used as a pre and post Emergent for a small variety of weed types. Good luck! Trying to wrap my head around some good methods myself.

 

I used Celsius on my centipede (or maybe I should say, I used Celsius on my Weed Lawn with a little centipede mixed in) and it definitely got rid of most, if not everything I had. Took a good 3 weeks to work though as it's still been cold.

Since Celsius is expensive for a little 10 oz bottle, it's worth checking the marketplace like I did. Got 2 oz for much cheaper and it'll last for my lawn for a good 2-3 years. 10 oz is overkill for this stuff.
