Snapshot 2.5 TG - 50 lbs. is not labeled to control nutsedge/grass. Pennant Magnum is the only pre emergent labeled for nutgrass/nutsedge and can be used in ornamental gardens and landscape plantings for both containerized and field grown ornamentals. Please view the full list of tolerant ornamentals this product can be used on starting on page 18 to 26 from the product label.
