Ferti-lome Over the Top II Grass Killer is not labeled to treat Torpedo Grass. Most of the herbicides will only suppress the torpedograss for a short time. It is recommended to spot treat the torpedo grass with a non-selective herbicide such as Round Up Quick Pro and then reseed or sod in the treated areas.
