Found some torpedo grass in St. Aug and small patch in centipede

Nuking the St. Aug area with round up.
Do the same in centipede area or Sethoxdim to try and preserve the centipede?
Edit making sure I am right with pics
Neighbor has it and brought in a lot of sand a couple years ago. Definitely coning to me from that side

Do you want to keep applying it to suppress the torpedo grass in the centipede? Sethoxydim will only knock it back and suppress it, not kill it.
How much are we talking? You can buy individual squares of centipede sod for cheap.

It is definitely a small area for the centipede. What sucks is that it is within an area I sodded last year for unrelated reason.

Edited op with pics of what I think is torpedo grass within St. Aug

Your centipede gonna die in a year or two anyway, might as well just speed up that process and take the torpedo with it.

After I nuke both areas, how am I going to keep it from coming back over separated only by a driveway?
I know that shite will blow over again after grass cutting or something

Sorry but torpedo is super aggressive and doesn’t respond well to any treatments. It’s a never ending fight unless you go postal.

Regular strength Roundup or strongest strength glyphosphate available?

Mow the clean side first and the torpedo side last. Blow the torpedo clippings back in that direction.
Ronk may be able to confirm/deny, but torpedo seeds are not that viable so you don’t have to worry much about spreading seeds to the other side the next time you cut. However, the rhizomes can grow under your driveway to the other side. It’s unlikely, but possible.

Lol it’s not supernatural. Regular, above average strength mix of glyphosate will kill it. You will have to repeat treat any other sprouts that return since it can survive pretty far below the surface. But glyphosate will kill what is there.
It is a nightmare to treat for and not harm the desirable grass though. Unless it’s in zoysia or Bermuda and can use quinclorac, you’re only [kill] option is glyphosate.

You’re right. Seeds are viable but really random. What makes torpedo a dickhead is that it is like a starfish. When you mow all the clippings grow roots. One runner of torpedo grass gets chopped up into 20 pieces and then you have 20 new torpedo grass plants.

I'm so glad to read this. I got areas of Torpedo coming up in my new Zoysia.
Looks like there are a couple of Quinclorac products. XLR8 and 75DF. Which one should be used on a 6 month old lawn (if either)? And should I go with the dilution strength on the bottle or less? Think I was reading it does best under 85 degrees so I'll wait until the fall to apply. Correct me if that's wrong also. I'm new to lawn maintenance. Just don't want to kill my lawn.

Man I don’t want to sound like Debbie downer but you are fricked. You will never stop it. Even if you dig the areas up and sod. It will come back. frick your neighbor.

There is no viable means to treat torpedo grass in SA that I’m aware of once it gets going.
I’ve found it greens first in the spring so you can carefully hit it all with roundup at the start of the season before the grass wakes up but it’s just slowing it down, you aren’t stopping it.
Until and unless they develop a selective herbicide for it in SA it’s just something you will have to come to terms with.

It’s in an area that you can’t see from the front of my house. Should I sod with a different grass there? So that I can spray a more selective herbicide once it comes back?
Just don’t want it getting to my front yard if possible

As someone who's a few years ahead of you dealing with the same problem. If you don't go all in on fixing it, RIP to your lawn. I didn't, and I've come to accept that if I keep it cut decently enough you can't really tell that the imposter is there.
You can keep going with sethoxydim and may have somewhat decent luck with that keeping it suppressed, but if it's a small patch and you want long term success, nuke that small patch with glyphosate. Dig up some of the rhizomes, buy some of those flower water things that you can slip onto the bottom of roses, fill those with pure glyphosate, and slip the rhizomes in them and leave them there for a few days.
Even then, you won't win. Housing market is a seller's market right now..

This makes a whole lot of sense. I've been passing over my front yard clippings to get them all into the front ditch and the front ditch is infested with it now. This stuff really is the devil, though I'd imagine if livestock eats it it's probably heaven sent
