Is there anything on the market to kill twitch grass? I have a great crop of it this summer.
Killing Twitch Grass

There is nothing that will kill only twitch grass. Round-up will kill it, but it will also kill the lawn or plants that the twitch grass is growing in and around.
The best way to get rid of it without endangering the surrounding plants is to hand pull it. It's hardiness is what makes it such a pain.
