Product Information
Q4 Plus Turf Herbicide
Q4 Plus Turf Herbicide has replaced Q4 Turf Herbicide.
Q4 Plus Turf Herbicide is a selective post-emergent herbicide. That means that it kills selective weeds and works after the weed has sprouted. Q4 Plus has a combination of four actives: Quinclorac, Sulfentrazone, 2,4,-D and Dicamba for a powerful knockdown on grassy and broadleaf weeds. This special formulation makes it unique among herbicides because it gets quick results with a broad, although selective, range of irritating weeds. Q4 Plus Turf Herbicide controls yellow nutsedge, crabgrass, foxtail, certain grassy weeds, and other troublesome broadleaf weeds in cool-season turf areas.
Mode of Action and Symptoms of Q4 Plus
The effects of Q4 Plus begin with stunting, then a gradual reddening and yellowing followed by plant death.
Quinclorac is absorbed through the root system and the other 3 active ingredients are contact herbicides, giving you multiple modes of action.
