PBI Gordon Q4 Plus Post Emergent Liquid Herbicide 2.5 gal. Jug (QGCY)

When tough unwanted growth is already visible and spreading, fast, broad control is the advantage that matters most. PBI Gordon Q4 Plus Post Emergent Liquid Herbicide delivers that speed and spectrum by combining four proven active ingredients into one powerful solution designed to clean up mixed plant infestations quickly and efficiently. Q4 Plus targets both grassy and broadleaf undesirable plants in a single application, making it a dependable choice for professional turf programs. Quinclorac provides strong post-emergent control of crabgrass and other listed grassy invaders, while sulfentrazone accelerates burn-down and improves nutsedge performance. The addition of 2,4-D and dicamba expands control across a wide range of broadleaf unwanted plants, helping eliminate escapes that single-mode products often miss. The liquid concentrate mixes easily and applies evenly, supporting consistent results whether used for spot treatments or full broadcast applications. Formulated for use on established cool- and warm-season turf, Q4 Plus delivers aggressive vegetation control with turf safety when applied according to label directions. The larger 2.5-gallon jug is ideal for contractors and large properties, reducing handling time and improving application efficiency across multiple jobs.
