Saint Augustine grass and Bermuda grass can coexist but there will be issues. Saint Augustine grass needs less fertilizer and usually grows faster. So it could make mowing the grass a frequent chore.
Plants are a complex mixture of thousands of different chemicals and do not have a "chemical formula."
Grass seed

There is not really any weed control out there that will kill one type of grass and not the other. If you want to get rid of Bahia grass in St. Augustine, you best bet is to spray the areas of Bahia grass with Roundup (the ready to use kind with the blue sprayer). Avoid as much of the St. Augustine as you can as Roundup is non selective, and then in the bare areas left by the dead Bahia grass you can put new St. Augustine in 7 days later. If the bare areas left are not too large, you can fertilize the St. Augustine encouraging it to spread into the bare areas.
