Fusilade II Herbicide is labeled to be used on St. Augustine grass to control bermuda grass only when tank mixed with Recognition Herbicide.
Fusilade II Herbicide is safe for established Blue Star Creeper when applied to young grassy weeds listed that are actively growing as directed. We recommend spot treating with a non-selective for the broadleaf weeds and use a pre-emergent herbicide in the spring and fall prior to weed germination.
Fusilade II Herbicide should not be applied to areas where edibles are or will be planted.
Fusilade II can only be used to remove bermuda grass from Tall Fescue and Zoysia Grass when used at reduced rates but it is not labeled for use on St Augustine grass so we cannot recommend it for this use. We are not aware of a product that is labeled to remove Bermuda grass from St Augustine.
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 GlyPhoSel Pro and kill it directly, and then replant St. Augustine in those areas.
Updated Jan 2025:Fusilade is not labeled to be used on St Augustine for bermuda grass control when tank mixed with Recognition Herbicide. Following these instructions Recognition Herbicide 2(ee) Supplemental Label-St. Augustine
