No, Gordons Ornamec 170 will kill your St Augustine turfgrass. 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 St. Augustine as well. In your situation, it is recommended to spot treat the Bermuda with Round Up and kill it directly, and then replant St. Augustine in those areas.
