MSMA (monosodium methanearsonate) and DSMA (disodium methanearsonate) killed 27 to 90% of the broomsedge (Andropogon virginicus L.) plants when applied at 1.1 to 6.7 kg/ha in July.

What herbicide kills broomsedge?

If only small amounts of broomsedge are present, spot spraying with glyphosate may be an option. While glyphosate is effective, if applied to actively growing broomsedge, it will also kill the surrounding desirable grasses.

How do I get rid of broomsedge?

Lousy feed: Broomsedge grows well in late season, but it's a lousy feed. Manage it by clipping it now and fertilizing to promote cool-season grasses. If you have it at full height now from last fall, consider clipping it down so it doesn't block sunlight form the new grass growth underneath it.
