Well, Quinclorac is not for use on Centipede. Vantage will kill it, but anything else it touches as well...Only other thing I can think of is Sulfursofuron. I remember when I was battling nutsedge a few summers ago, that it seemed to burn back the Torpedograss significantly. May be too expensive to be a viable option, though.

Thanks bootlegger. It's my understanding that Vantage won't Kil centipede if applied correctly. I've had some success with this product controlling Bermuda. I may give it a try and look into Sulfursofuron.

Read up on that Vantage label before applying...I thought it was just Dow's version of Roundup...I could be wrong though
Sulfosulfuron is most likely sold under the brand name Certainty. It's not listed for Torpedo, but I saw burn-back when I used it. Personally, I probably wouldn't spend the dough on a chemical that isn't listed for what I was trying to kill
If the Vantage doesn't work out, I will run a test plot with the Sulfosulfuron I have and get back to you with before and after pics .

Amazed at all the attention given to yards, and the knowledge you guys have about grasses and treatments.
Mine just gets treated with Lettergrow and Cuttitback. Looking forward to the cooler weather so I can slack up on both treatments.

I do athletic field turf management for a living, so that bleeds over into my yard as well
I, too, am ready for the cool down so I can change my focus to hunting

This heat and mini-drought has helped - no rain since 7/4.

Good luck OP torpedo is the devil! Coming from NOLA I had it in all my yards and gardens. I moved to laffy and left all my lawn equipment at the old house. Got all new and had a fresh sodded lawn....then got lazy and got a law service. They brought in torpedo and I tried to fight it off in st aug. Going as far as using a cloths pin with sponges on the ends so I could treat just the torpedo. I gave up after a cpl years...and have since moved and left all lawn equipment again. I dont even like looking at it online 
Most here dont even know what it is...

Close enough to St. Aug for me.

The most success I've had at keeping this stuff in check is applications of round up either spot sprayed or wiped on twice a week for 8 weeks. When it looks completely dead just keep spraying it

Dealing with it for the past several years here in New Orleans. Took me a while to figure out what it was, but it is the most persistent, annoying shite ever. Applying Roundup at 2x max recommended concentration by hand with gloves works, but if you are not religious about keeping up with it, it just comes back. It will also bust through any mulch or weed fabric like it's no big deal.

Still, I can't make your pics look like the pics of torpedo I have found. How do the plants connect to one another, if at all? When you pull it, do you ever end up wit hthis type structure?
I'm really hoping it isn't the torpedo grass because it seems like that stuff is hard to get rid of completely,
Another grass I've never seen is Signal, but some of the pics sure look like yours,

yall just need to squint. It looks just like St Augustine if you blur your eyes up real good.
Posted on 7/24/15 at 3:37 pm to AlxTgr
That's why I said the second set of pics was Torpedograss... The first set didn't strike me as torpedo. shite gets tricky, for sure. Dr Strahan at the AgCenter probably hates me because I email him so much for weed ID

Some grass makes rhizomes, which are root structures you can't easily kill, etc. Johnson grass is another rhizome grass, Bermuda probably is, too.
Posted on 7/24/15 at 4:21 pm to White Bear
Here some more pictures I took in the full daylight, including one I found that was flowering. I agree though, starting to waiver on the Torpedo Grass ID.
Posted on 7/24/15 at 5:27 pm to White Bear
Bermuda has stolons and rhizomes...that's why it's such a bitch to get rid of.
Posted on 7/25/15 at 9:21 am to Marineaux
The torpedo grass ID is correct. If it is real bad we scrape it out and install zoysia or Bermuda. At least you can use a selective herbicide with those.
