What kind of grass is this and how do I get rid of it?

I'd venture to guess that is Torpedo grass.

If it is torpedo, the easiest way to get rid of it is to contact your real estate agent to list your house, then move somewhere else.

There's no getting rid of it, but for centipede you can apply sethoxydim 2 or 3 times over the course of a month or so and really knock it back. Then applying sethoxydim once a year is pretty effective.

Dangit. I was afraid of that.

I didn't do any river silting myself but I wouldn't be surprised if the developer cut corners. Guess it will just be a pain in my arse until I move.

Torpedo grass can grow out of your arse too.

In 2005 I got some river dirt hauled and sodded with emerald zoysia. I didn't know about TG back then. I had two spots emerge with TG. I'm lucky that's all there was. One spot by the road and one behind the house. After 17 years, I have two spots of TG. One spot by the road and one spot behind the house.

Over the years I've stayed on it and have never let up. It hasn't spread. Straight 41% Roundup rubbed on by hand only temporarily kills it. It always comes back. A couple times it even got kinda thick in the spot by the road. But right now, it's as close to eradication as I've been. Zoyisa is pretty tolerant of Drive XLR8 and Quincloric 75 that say they control TG. They certainly don't control it when used as directed. But I've been spot spraying with the Drive, and sprinkling the Quin 75 granules on it and around it while wet with Drive, to get a lasting effect and ground penetration through multiple rains. I think the sustained, uninterrupted attack is working/ Certainly better than anything else I've tried. I started that last year, and I only have two sprigs that came up by the road, and one sprig behind the house. They've been re-treated that way and are currently gone. But with TG, unless you go a few years without seeing any at all, I don't think you can really say you got it. But I think I will preemptively sprinkle the granules over the area in the fall and maybe again in the winter. I'm more encouraged than ever that it may be possible to end it. The zoysia does take a hit with this regimen, but not even as much as spot spraying with roundup, which TG laughs at. Unfortunately, I think with Drive and Quin75, you'd easily kill your centipede. I don't have centipede, so I'm not real familiar. But it seems there is something you can use on centipede for TG that Zoysia doesn't tolerate. I don't remember the name. It probably doesn't work when used as directed, but maybe using it along the lines of how I am, may help. But I have to say, if your whole yard looks like that, I don't think you'll ever get rid of it. I started with a much smaller distribution.

For the post above that said his neighbor killed with roundup and re-sodded- I can almost guarantee it will come back, unless maybe he sprayed it completely dead with several follow ups before re-sodding.

Edit: Google
In centipede lawns, you can use the herbicide sethoxydim (Vantage or Poast) to suppress torpedograss. It does not hurt centipedegrass if applied as directed. Repeated applications (at least three) through the summer will keep it suppressed -- not eradicated. If you ever stop spraying, it will come back.

Maybe some form of using that the way I've used Drive XLR8 and Quinclorac 75 may have a chance.

If I were trying to kill everything and start over, rather than use Roundup (guaranteed to come back imo), I'd go heavy and repeated with Drive and Quin75 and probably wait until well into the next spring to watch for re-emergence, before re-planting.

Prayers sent.

If you were in Texas with grass like that you would be the talk of the town right now.
Point being looks good to us
