This is one weed I can’t seem to manage. It’s popping up all over my yard, flower bed, rock bed, hedges by the pool. I literally thought of torching my yard and starting over. What can I do to get rid of this monster?

Start over. If it’s in your lawn and flower bed you’ll have to redo everything. Remove all shrubs, round up lawn and flower bed, round up again in two weeks, kill your neighbor and hide the body, set his yard on fire, level lawn while it’s bare, sod.

Funny you say that, that’s what the people at Plant tech recommended.

But if it’s in the neighbors yard, won’t it just come back? Ideally I would like to set everyone’s yard on fire, but that’s not feasible. I even put Pramitol 25E on it, and I feel like it didn’t phase it much at all.

If it is in the neighbors yard then it will be a nonstop, constant battle.

move out. The only thing you can do is control it.

What’s the strongest chemical I can buy that I can apply in the rock bed and temporarily treat it?

sethoxydim will suppress torpedo, but it will come back, so you have to treat regularly. It will kill Bermuda but safe for centipede and st aug.

Just buy glyphosate concentrate and don't dilute it.

If you have Zoysia, then Quinclorac will suppress it but you'll still lose.

Sethoxydim will kill St. Aug before it suppresses torpedograss.

I appreciate ronk's passion here. My yard was beautiful when I bought my house. The neighbor had just built shortly before that. The dirt my neighbor's contractor brought in was full of torpedo seeds and now, three years later, it's travelled 100 feet across my yard to my driveway, even with sethoxydim treatments twice per year.

Even if you go scorched earth with glyphosate, salt, battery acid, whatever, satan himself will spawn it back to life. I'm pretty sure the floor of hell is covered in torpedo grass and the devil is having the same problem.

I’m pretty sure this is true, I’ve used everything I can think of and it hardly phases it. I’m thinking of ripping everything up and decking the rest around my pool, and doing artificial turf and bushes around the rest.

They brought in soil with root segments in it. Torpedo doesn’t have a viable seed, according to Dr Strahan

I bought one of these Flame King and burned a good bit of my torpedo grass. Will hit it again if any survives.

not my experience. I read a comment saying while it's not labeled for it, they have seen their st was able to withstand it. I have spot sprayed one application earlier this year and didn't see any st Aug die. I hope I'm right because I just sprayed again this evening. Granted my yard is a mix of st Aug, centipede, bermuda, torpedo, crab, sedge, green killingya.

Good luck. My front yard is centipede and my back yard is St Aug. I can confirm it kills St Aug.
