This unique product provides both pre-emergent and post emergent control of both grassy and broadleaf weeds – including nutsedge, goosegrass, ground ivy and others. Systemic action from the leaves down and the roots up inhibits cell division and disrupts photosynthesis. Works equally well on cool and warm season grasses. Weed Beater Complete is a synergistic combination of prodamine and sulfentrazone. Exhibits excellent cool weather performance. 10lbs treats up to 5,200sq ft.
