Image Kills Nutsedge Concentrate is not labeled to kill torpedo grass. Unfortunately, most of the herbicides we carry will only suppress torpedograss for a short time. In most cases, it is recommended to spot treat the torpedo grass with a non-selective herbicide such as Round Up Quick Pro, and then replant in the treated areas in a couple of weeks when the torpedograss is gone.
