Q4 Plus Broadleaf Weed Herbicide (Controls Nutsedge, Foxtail, Crabgrass) - 1 Quart

PBI Gordons Corp


Q4 Turf Herbicide for Grassy & Broadleaf weeds

Q4 Plus Turf Herbicide is a patented product containing four active ingredients, Quinclorac, Sulfentrazone, 2,4-D, and Dicamba, for control of a broad spectrum of both grassy and broadleaf weeds through multiple modes of action in established cool-season and bermudagrass turf areas. This combination offers the professional turf manager more knockout power and the speed associated with the Gordons line of Proform products. Weeds controlled include yellow nutsedge, crabgrass, foxtail, and many more. Q4 Plus is highly selective on coolseason turf grasses. Use sites include lawns, golf courses, cemeteries, public parks, sports turf, sod farms and other sites. Labeled species include bluegrasses, perennial and annual ryegrasses, fescues and bermudagrass. Q4 Plus is rain-fast in 6 hours and has a one week reseeding interval. Q4 Plus has dramatically less discoloration on cool-season turf compared to MSMA. Call-backs are a thing of the past when your clients and members can see fast results, usually within 24 to 48 hours.

      My go to post emergent herbicide

      It’s the best I’ve found. Seed Word is very dependable. Just sent a quart to family member. I’ll keep using Q4 & Seed World.
