Eliminate broadleaf weeds and grasses with Quincept, a powerful weed killer for use on residential and commercial land. It contains three active ingredients to target, treat and prevent invasive weeds and grasses from ruining lawn turf and landscaping. It controls numerous hard-to-kill weeds in many different application sites such as parks, roadsides and home lawns. If you need something more powerful than a traditional weed killer, get total control with Quincept herbicide.

How Quincept Herbicide Works

Quincept contains quinclorac, dicamba and 2,4-D as the active ingredients. These three ingredients combine to eradicate broadleaf weeds and grasses by promoting uncontrolled growth and death. You can apply it as a clean-up herbicide in the spring to treat areas that missed a pre-emergent application. It also works effectively in the summer to kill postemergent weeds that pose problems to beneficial plants and turf.

Where to Use Quincept Herbicide

Use Quincept herbicide where weeds cover turfgrasses and plants in residential and commercial areas. It keeps barnyardgrass and chickweed out of residential landscapes and dandelion from invading parks and recreational fields. Some of the more common application sites include:

  • Exterior commercial establishments
  • Parks
  • Athletic fields
  • Church grounds
  • Picnic areas
  • Golf courses
  • Cemeteries
  • Sod farms
  • Airports
  • Roadsides
