Natural Guard Lawn Weed Killer Selective RTU is not OMRI listed.
Natural Guard Lawn Weed Killer Selective RTU is a cool weather broadleaf weed killer, it will not effect any grasses.
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 a non selective herbicide and kill it directly, and then replant St. Augustine in those areas.
We do carry a few professional Round up products as well as glyphosate/Roundup alternatives.
Natural Guard Lawn Weed Killer Selective RTU is not labeled for the treatment of lespedeza.
