PBI/Gordon Corporation has recently received EPA acceptance for a new turf herbicide for grassy and broadleaf weed control. The new-patented formulation contains the protox inhibitor sulfentrazone in combination with quinclorac, 2,4-D and dicamba.

Trademarked as Q4 Turf Herbicide for Grassy and Broadleaf Weed Control, the new product will join Gordon’s ProForm brand, which includes SpeedZone, PowerZone, SpeedZone Southern and Surge herbicides. The Q4 label will feature the distinctive checkered flag design in orange.

The new formulation is designed for use on cool-season turf. Adding 2,4-D and dicamba broadens the weed control spectrum and adds systemic activity to the contact activity of sulfentrazone for multiple modes of action.
