Controlling over 90 different broadleaf weeds and sedges is easy with ArmorTech 4-Runner, by United Turf Alliance. An alternative to 2,4-D formulations, 4-Runner provides the broad-spectrum control lawn care operators expect—and starts showing observable results within hours of application. 4-Runner is a post-emergent herbicide that contains four powerful active ingredients that work together to provide quick, effective control, all while being gentle on turfgrass.

Excellent Tolerance

While it may be tough on weeds, it’s not tough on turf, making it a safe choice when treating customers’ lawns. It exhibits a high level of tolerance, and it is safe to use on cool- and warm-season turf types. It also has excellent cool-weather performance, too, outperforming conventional amine 3-way herbicides.

Broad-Spectrum Control

4-Runner provides broad-spectrum, post-emergent control over some of the most tough-to-handle weeds and sedges, including clover, oxalis, dandelion, ground ivy, and yellow nutsedge. Read 4-Runner’s label for a full list of the 90+ weeds it controls. Since it works fast, it should be easy for customers to notice when 4-Runner is working, and its effectiveness means you’ll likely have fewer callbacks, too.

4-Runner Use Rates

On cool-season turfgrass types (Kentucky bluegrass, annual bluegrass (Poa annua), annual ryegrass, perennial ryegrass, tall fescue, and fine fescue), spray 1.1 to 1.7 fluid ounces per thousand square feet. If the turf being treated is exhibiting heat or drought stress, use a reduced rate. Apply 4-Runner when weeds are actively growing and are small for the best control.

On warm-season turfgrass types (bermudagrass, centipedegrass, zoysiagrass, and bahiagrass), spray 1.0 to 1.3 fluid ounces per thousand square feet. LCOs should use lower rates on centipedegrass until its injury tolerance can be gauged. 4-Runner should not be applied on warm-season turf during green-up or during its transition to dormancy in the fall. As with cool-season grasses, spray 4-Runner when weeds are small and actively growing to get the best results. 

Applying 4-Runner

Applying ArmorTech 4-Runner is straightforward. 4-Runner should be mixed with 0.2 to 5.5 gallons of water per thousand square feet. When spot spraying, spray one gallon of solution per thousand square feet. When using low-volume equipment, keep application rates low (as little as 0.2 gallons per thousand square feet).

Don’t apply 4-Runner on:

  • newly seeded areas until turf is well-established.
  • areas that have been sodded, sprigged, or plugged for at least four weeks.
  • grass seedlings until after the second mowing.
