Long-Lasting Weed Control Before Weeds Ever Appear
Resolute® 65WG is a professional-grade pre-emergent herbicide designed to stop weeds before they can germinate. Powered by 65% Prodiamine, Resolute creates a long-lasting barrier in the soil that prevents grassy and broadleaf weeds like crabgrass, goosegrass, annual bluegrass (Poa annua), foxtail, spurge, and more from ever taking hold.
This product is ideal for homeowners who want season-long weed prevention with fewer applications and results you can trust.
Important: Resolute 65WG does not kill existing weeds. It must be applied before weed seeds germinate.
Established residential lawns
Sod farms & non-putting-green turf
Landscape beds & ornamental areas
Warm-season and cool-season turfgrasses
🚫 Not for use on golf course putting greens
Resolute 65WG works by forming a protective barrier in the soil that prevents newly germinated weed seeds from developing roots and shoots. Once watered in with ½ inch of rainfall or irrigation, the product locks into the soil and provides months of residual control.
