Bio Advanced Bermudagrass Control RTS is labeled to kill bermudagrass but it is not safe for St Augustine. There is not a selective herbicide to eliminate bermuda out of St Augustine since they are very closely related. You can use a non selective like glyphosate to spot treat it and then resod the areas 2 weeks after the last application.

Since the Bio Advanced Bermudagrass Control RTS is labeled for use only around ornamental plants, we cannot recommend that you spray this within the dripline of any ornamental plants such as grapevines.

Bonide Grass Beater is labeled for use for grass control around grapes; there is a 50-day pre-harvest interval for that product. Otherwise, you may use a non-selective herbicide such as Avenger Herbicide as needed.
