Eliminating Torpedograss in the Lawn

Kill patches of torpedograss in the lawn with glyphosate. It will take out a bit of the turf but you can remove the dead vegetation and reseed. A kinder, gentler method in Bermuda grass or zoysia grass is to use a formula with quinclorac. In centipede turf, use sethoxydim.

Keeping this in consideration, how do you treat Torpedograss?

There are no herbicides to selectively control torpedograss in other types of lawn grasses, such as St. Augustine grass. You can kill patches of torpedograss with glyphosate (keep this off the desirable grass as much as possible). When the torpedograss is brown, remove it and resod the spot with your lawn grass.

Additionally, does vinegar kill Zoysia grass? Zoysia is a very tough grass, which is great in warm climates, as it grows so thick that it prevents the growth of weeds, and because it also grows more sideways than up, it requires less mowing. If boiling water does not work, you can kill it using a propane torch to burn it. Vinegar has also enjoyed good success.
