re: What can kill Torpedo Grass in flower beds?

I grow a pretty big vegetable garden and have, over the years dealt with just about every invasive weed you can think of. Torpedo grass, nut grass, bush killer vine, oxalis, purslane, etc. and it is a never-ending battle.

Seems just when I get one weed under control, or at least manageable, something else comes along and takes hold.
