Don't be so glad to read this. You're not much better off with zoysia. I've had emerald zoysia since 2005 with a couple spots of TG. Thought I was finally done with it last year, but I have a tiny spot (one or two stems with blades)that re-appeared this year. I used to have much more than that, albeit still two isolated areas. I do think I will prevail soon under my current regimen. I find Quinclorac works better than Drive XLR8. But I mix either one as directed, spray the blades wet. Then I sprinkle the area lightly with the Quinclorac granules, and mist again to partly dissolve. What's on top dies dead. And I really do think that sprinkling the granules gives a residual effect in the soil through the next rain, and if repeated, finally wins out. I have won out most of the affected area, and expect to for this last little spot that reappeared. I just started trying the sprinkling last year, and I'm better off now than at any time since 2005. It does stress the zoysia, but hasn't killed it. If I had centipede or st aug and was going the nuke route, I'd do what I described. Glyphosate/Roundup just doesn't have a lasting effect, even when applied straight at 41%. I really think you need residual quinclorac in the soil to prevail.

Yes, I would. And I would hold off re-sodding for a while, as the new sod probably wouldn't tolerate it for a while unless you remove dirt and replace it with fresh dirt. It's hard to know how big of an area you're dealing with. But it looks to be well-flourishing in those small pics posted. And I know this won't sound appealing, but if it were me, I'd write off having good grass there this year. I'd make the initial application as described, repeat a month later even if it hasn't come back, and wait an extended period of time after the second round to see if any comes back before re-sodding, or you risk starting all over. That timeline takes you to fall. Maybe even let less difficult weeds fill in the area until next year. Then work on those easier weeds first thing in the spring before re-sodding, even if it takes round up at that point. Then re-sod. If it's too big of an area to do that, I don't know what to say. It cannot be overstated how difficult torpedo grass is to deal with, and how resilient it is. I'd compare it to cancer, but it's more like gangrene. I wish you the best. It's going to take ridiculous effort and diligence to cure.

I have some also. Can't tell if the part of my yard is centipede or Bermuda. It's kind of a mix. Anyone see a problem with trying quinclorac and if it nukes the grass then so be it. Just re sod after?

You could post pics. The people here can tell you if it is centipede or Bermuda

I am going to give that a try. Since it is at side of house, I can wait it out a while

Will talk to neighbor soon. Yes I know it may be a long shot to get him to nuke his whole yard.

If I had a lot of torpedo my approach would be different. I would focus on walling off my garden beds with subterranean sheet metal then let the torpedo grass flourish and embrace it. As long as it’s not popping up in the garden it’s a green grass that doesn’t look bad mowed short and requires no fertilizer.

Embrace it.

My grass is a mix. It's definitely in the Bermuda. I ordered the quinclorac. I will give it a shot. It's that or roundup

It doesn’t get super green and you have to mow it every 3 and a 1/2 hours to keep it short.

Yea but what’s the alternative? The guy is talking about constantly dusting chemicals when it’s just going to come right back from the neighbors. Some battles just aren’t worth fighting.
