Unfourtunally Pennant Magnum Herbicide is labeled for pre-emergent control of yellow nutsedge but does not list green kyllinga on the product label. Unfortunately there is not a pre-emergent labeled for green kyllinga. Green Kyllinga is controlled with post emergents like Sedgehammer + Herbicide. Please check the product label fo make sure your turfgrass is listed as tolerant.
