One company announced the U.S. EPA registration of Allstar™ Herbicide, a new fast-acting herbicide for use on cool-season turfgrasses developed to single-handedly control grassy weeds, nutsedge and tough broadleaf weeds like spurge, clover, dollarweed, ground ivy, oxalis, wild violet and Virginia buttonweed. 

Allstar features a unique combination of four active ingredients – 2, 4-D, Quinclorac, Sulfentrazone and Triclopyr – to provide turfgrass professionals with a quick and effective tool to control an extensive spectrum of difficult-to-control weeds throughout the summer season.

″Lawn care professionals working with cool-season lawns have been looking for a fast-acting, cost-effective solution for stubborn weeds like ground ivy, oxalis and wild violet,″ said Jamie Heydinger. ″Allstar’s formulation has prioritized effective loading across four key actives to provide customers with greater confidence in treating complex summer weed challenges without callbacks.″

Allstar’s fast-acting formula provides visible results within hours of application and is labeled for many cool-season lawns with tall and fine fescues, annual and perennial ryegrass, Kentucky bluegrass, annual bluegrass, rough bluegrass, and Bentgrass, as well as hybrid and common Bermudagrass and zoysiagrass.

With a wide treatment window spanning the summer season, Allstar is designed as a cost-effective solution for turfgrass challenges with persistent difficult-to-control weeds. Allstar availability and state registrations are anticipated through the fall of 2024 for use on residential and commercial lawns, sports turf and golf course fairways and roughs.
