Gordon's Q4 Plus Turf Herbicide for Grassy & Broadleaf Weeds
Q4 Plus from PBI Gordon is recommended for the control of crabgrass, yellow nutsedge and certain grassy weeds, such as foxtail and for the control of most troublesome broadleaf weed species in established cool-season and bermudagrass turf areas. Use sites include lawns, golf courses, cemeteries, public parks, sports turf, sod farms and other sites.
Contains four (4) active ingredients: Quinclorac + Sulfentrazone + 2,4-D + Dicamba and was designed to replace Trimec® Plus. With MSMA disappearing from use on residential and commercial turf, Q4 Plus offers the professional turf manager more knockout power and the speed associated with Gordon’s line of ProForm® products.
Q4 Plus contains 0.75 lbs. ai/acre of quinclorac for enhanced control of grassy weeds such as crabgrass and foxtail. Quinclorac is absorbed by both the leaves and roots and translocated throughout the plant. The effects on grassy weeds include stunting, gradual reddening and yellowing followed by plant death. Q4 Plus also contains sulfentrazone, adding fast-acting yellow nutsedge control as a bonus. Formulated with precise ratios of 2,4-D and dicamba, the weed spectrum is broadened. The combination of these ingredients results in systemic and contact activity with multiple modes of action.
Like Trimec Plus, Q4 Plus offers a single product control option for yellow nutsedge and grassy and broadleaf weed control in established turfgrass areas. Users appreciate the convenience of one product for crabgrass, yellow nutsedge and broadleaf weed control making this a versatile all-in-one product.
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 with 24 to 48 hours.
Q4 Plus is highly selective on coolseason turf grasses. Labeled species include bluegrasses, perennial and annual ryegrasses, fescues and bermudagrass. Q4 Plus has a CAUTION signal word, a good toxicological profile, is rain-fast in 6 hours and has a 4 week reseeding interval.
