The SedgeHammer 13.5 gram box already contains a surfactant so no additional surfactant would be needed. If you are using the 1.33 oz bottle of SedgeHammer, we would recommend using Non-Ionice Surfactant for Herbicides. If using the 1.33 oz. bottle, use 0.9 g (one spoonful) in 1-2 gallons of water with 2 teaspoons of a nonionic surfactant.
