Unfortunately Bermuda grass is so closely related to St. Augustine grass that there is nothing that will remove Bermuda from St. Augustine and not hurt the Bermuda as well. In your situation it is recommended to spot treat the Bermuda with a glyphosate product and kill it directly, and then replant St. Augustine in those areas. GlyPhoSel Pro would be a good one to use.
