Rob from Ozark, Ar writes
I have a wildflower meadow which is being outcompeted by broomsedge, which is a native grass. I don't want to start from scratch by killing everything with Roundup.
Gordons Ornamec Over-The-Top Grass Herbicide is not labeled to control broomsedges, only certain types of grasses. We would recommend to contact your local cooperative extension office and speak to the master gardener for more information regarding control and only mentions using glyphosate to kill it. Most of the literature we're finding has to do with cultural control rather than herbicide control. Here's a link we were able to find, I hope it will be useful: http://plants.usda.gov/factsheet/pdf/fs_anvi2.pdf
