Best action would be to move!
However, UF's Lawn Handbook says to use
Asulam [methyl sulfanilylcarbamate]
which is sold as Asulox®

jhurst, the selective control for torpedograss in bermudagrass is Drive 75DF by BASF. Asulam (Axulox) will have little or no effect.

Drive 75DF can only be applied at 2 pounds per acre per year, and that's not enough to to remove torpedograss in one year. Therefore, it should be applied in small increments, e.g., three applications of 2/3 pounds per acre, which causes a slow kill.

It may take three or years of serial treatments to get rid of torpedograss.

Is there a selective control for torpedo grass that can be used in centipede lawns?

You can use Vantage to control torpedo grass in centipede. I,ve used it with good success. You will need to reapply to keep torpedo grass under control.

I have just purchased the Drive 75 for torpedo grass in zoysia, central Fl. I am going to do three treatments every two weeks at a reduced rate. I need to find some methylated seed oil to mix with it.
I found lesco spreader sticker but I don't wan't to buy a gallon. Any ideas where to find small quantities of a adjuvant??
I am only spot treating with a sprayer.

The only way to get rid of torpedo grass in flower beds is to carefully dig very deep around the grass without injurying it. Then flood the grass and the area around it with a grass and weed killer and leave it exposed for a week or two before replacing the soil. It is a very tough weed and grows underground in extensive networks.

I have some areas with Torpedo Grass in my St Augustine lawn and also in a flower bed. Ican kill it with MSMA but it kills the desirables as well.

Last year after pulling and digging a lot, I sprayed a circle with cooking oil. In the heat of the summer it killed the rhizomes. I am planning on trying the cooking oil with a jersey glove this year just without the pulling.
