What herbicide kills weeds in fine fescue?

Dicamba, mecoprop, triclopyr, and 2,4-D are herbicides that kill weeds in fine fescue. The best known fine fescue is red fescue (Festuca rubra) because of fine leaves for soft matting, low fertilization and irrigation need, and shade and sun tolerances. It tends to overseed dormant Bermuda grass lawns and will tolerate established turfgrass herbicides except for 2,4-D + dichlorprop + dicamba.
