Product Description: SedgeHammer® targets bothersome weeds like yellow nutsedge and certain broadleaf weeds. This weed killer is a “WDG” which stands for “Water Dispersible Granule” meaning the product is dry, and you mix it in water and spray it.
SedgeHammer® comes in a 1.33 oz bottle of highly concentrated Halosulfuron-methyl. It comes with a small scoop and one level scoop is added to 1 gallon of water to cover 1,000 sq ft or for spot sprays. The 1.33oz bottle can cover 1 acre approx 43,500 sq ft. You will want to add a surfactant along with this product in your tank for maximum effectiveness
Because this weed killer is safe for grass, it does work a little slow. It can take up to 21 days to see full results but it works very well against yellow nutsedge and other weeds as long as you are patient.
