We do carry selective post-emergent herbicides that may harm the bahiagrass and safe for fescue but because they are closely related, we recommend contacting your local Master Gardener for a recommendation for treatment in your area. Please let us know the product and if it something that we currently do offer, we will try to obtain it for you.
