PBI Gordon Q4 Plus Post Emergent Liquid Herbicide 1 gal. Jug (QGCY)

Fast, visible unwanted plant control is the clear advantage of Q4 Plus, delivering broad-spectrum performance when unwanted growth is actively developing and turf needs quick recovery. PBI Gordon Q4 Plus Post Emergent Liquid Herbicide combines four proven active ingredients to knock down tough broadleaf and grassy plant intrusions with noticeable results in days, not weeks. This multi-mode formulation targets some of the most challenging invasive plants in turf, including crabgrass, clover, dandelion, nutsedge, and foxtail. Quinclorac provides strong grassy plant control, while sulfentrazone enhances speed of action and improves nutsedge performance. 2,4-D and dicamba expand broadleaf control, ensuring more complete coverage across mixed infestations. The liquid concentrate mixes easily and applies evenly, making it well suited for spot treatments or full-area applications in residential, commercial, and institutional turf. Designed for use on established warm- and cool-season grasses, Q4 Plus delivers aggressive vegetation control while maintaining turf safety when applied according to label directions. Its quick visual response helps turf managers evaluate results faster and make timely follow-up decisions with confidence.
