I have Monkey grass with St Augustine grass growing in it. Is there something I can spray on the area that will kill the St Augustine grass but not the Monkey grass?

Monkey grass should not be affected by grass specific herbicides, like Grass B Gon. They are designs to harm lawn and weed grasses rather than ornamental grasses. Just to be safe though, test on a small area before spraying the whole area.
