Abstract

The objective of this study was to observe the effectiveness of Sedgehammer 75WDG (Halosulfuron) and Dismiss 4F (Sulfentrazone) on yellow nutsedge (Cyperus esculentus) control. It was conducted at the Iowa State University turfgrass research area in a non-irrigated area of mixed grass species that contained a high population of yellow nutsedge. The Sedgehammer was combined with the X77 surfactant at 0.25% v/v. No surfactant was used with the Dismiss. Plots measured 5 × 5 ft for a total of 25 ft² and the study was replicated three times. Treatments were applied in the equivalent of three gallons of water/1000 ft².
