Torpedo grass…..
I think I may have won my battle. I caught it early. Pretty sure it came in with my landscape. Luckily the rain allowed me not to cut my grass and I saw it popping out. I just Nuked it with round up until I didn’t see it anymore. Been a couple weeks and haven’t seen any new. I’ll just cut the dead patches and re sod the area.

Now on to the dove grass and other miscellaneous shite that I haven’t been able to spray for since it rains everyday

Roundup is pretty effective on it. I had some come in with my river sand. I used roundup and some quinclorac and it seems to have knocked it out.

With all this damn rain I’m gonna need a couple bottles of sedgehammer though.

re: Torpedo grass…..
Took every precaution when I built my house and sodded my yard. Then this shithead landscape company put in some dirt mix that was full of some kind of Bermuda looking shite. Knocked that out so m pretty sure because of the timing of the torpedo it had to be from him. frick moving. Got too much in this house. I’ll dig up my yard and go synthetic if anything

re: Torpedo grass…..
No zoysia and it’s short which is why I was able to catch it early. Haven’t cut grass but once in the last month.

Quinclorac should kill it I thought?

It will be back. Sorry to tell you. I've had a couple unnoticeable, small spots in emerald zoysia since 2005. Tried everything from hand-applying straight 41% roundup with gloves and rubbing all of the foliage with it, to baking soda, to quinclorac and drive xlr8. ive been able to keep it from spreading. but it always rears it's ugly head again after you think you have it. never had it reach the seeding stage ever. But the roots just don't die. i've always just spot sprayed. but maybe a wide swath with quinclorac/drivexlr8 would be better and keep it from pulling life from untreated soil. idk

re: Torpedo grass…..
No I nuked the area with roundup. 3-4 times over the last month.

I still think it will be back. I don’t even like reading that word

I sincerely hope you never see it again. I really do. And you might not for some time, maybe even a whole year or more. Then when you least expect it, you'll see that one blade emerge again, and you'll feel that lump in your throat. I hope I'm wrong. I'd have a hard time being confident unless I did what you did and then excavated the whole area a few feet deep in an attempt to remove all traces of it. But that's not really practical. You did the best you can practically. Otherwise, just have to hope for the best.

While you have the dead spot, if you don't mind having a bare spot until next year, you could try a residual/soil sterilant herbicide. That would be an extreme measure not intended for home use, and maybe an consideration if there's a "next time". This is an example:

Pramitol

quote:

Pramitol 25E is a non-selective pre and post-emergent bare-ground herbicide concentrate popular for industrial and commercial applications. Bare Ground means exactly that, wherever Pramitol is applied, nothing will grow for one year or more. Apply before or up to three months after weed emergence. Dilute in water or oil and apply as a foliar application, before construction, or in or under asphalt to control johnson grass, bindweed, wild carrot, and other hard to kill weeds and grasses. Pramitol 25E will not control woody vegetation. Pramitol is ideal for use around buildings, storage areas, roadways, airports, highway medians, lumberyards, pipelines, fences, recreational areas, and similar areas where total weed and grass control is needed.


This is another. You can further research these types of nukes, as they may require licensing to purchase.

re: Torpedo grass…..
Game plan is to let it sit dead for a few more weeks and see if anything new pops up. Then dig up grass, another application or two then re sod. I’ll post back later win or lose

It really blends with zoysia and I keep my yard at 3/4” or so. I’m going to skip a cut or two after this one this weekend.

re: Torpedo grass…..
When I lived in gonzales there was a local cooperative that gave some great ideas on what works on Torpedo grass. It was pretty insightful- I never had much success with roundup.
Good luck. Torpedo grass is the worst.

re: Torpedo grass…..
A kinder, gentler method in Bermuda grass or zoysia grass is to use a formula with quinclorac. In centipede turf, use sethoxydim. This will kill the torpedograss but not damage the lawn. Many other lawns have no recommended selective herbicide.

re: Torpedo grass…..
Maybe try that if it pops back up. I’ve searched those selective for zoysia but didn’t have time. Wanted to knock it out. I’ll start digging the dead spots next week and re sod the area
