Get rid of weeds fast with 4-Speed XT post-emergent herbicide. This potent weed killer goes to work quickly and starts to kill weeds in less than 48 hours. It's formulated to kill many different broadleaf weeds on residential lawns, business landscapes and other grassy areas. Whether it's dandelions or clover patches, 4-Speed herbicide knocks out weed infestations with one application.

How 4-Speed XT Works

4-Speed XT weed killer has four ingredients to help it knock down weed infestations fast: 2,4-D, triclopyr, dicamba and pyraflufen-ethyl. These ingredients combine to kill weeds in as little as 24 hours depending on the species. The primary ingredient 2,4-D affects cellular growth in weeds and inhibits their ability to photosynthesize. It works on both cool- and warm-season grasses and prevents weeds from stealing nutrients from lawns. It's applied easily with sprayer equipment and covers hundreds of acres in one container.

Where to Use 4-Speed XT

Because it doesn't harm cool- or warm-season grasses, use 4-Speed anywhere weeds have taken over the turf. Eliminate clover infestations in residential yards, knock down foxtail on commercial landscapes, and get rid of ragweed on roadsides. It has a fast-acting formula that kills hard-to-control weeds once they've emerged from the soil. When weeds pop up, use 4-Speed XT weed killer in the following places and more:

  • Business parks
  • Recreational areas
  • Golf courses
  • Sod farms
  • Rights-of-way

Target Weeds

A post-emergent herbicide is formulated to kill weeds that have already emerged from the soil. 4-Speed is made to target those weeds and knock them down quickly. It's not for use on pre-emergent weeds that are still below the soil. It's the ideal herbicide for use on chickweed and thistle, killing them in one to two days. It's also perfect for stopping ragweed growth in lawns and causing allergies in residents. Use XT post-emergent herbicide to kill these weeds and more:

  • Beggarweed
  • Clover
  • Crabgrass
  • Dandelions
  • Mallow
  • Knotweed
