Rectangular Herbicide is the generic alternative to SquareOne Herbicide, delivering the same fast, selective post-emergence control of crabgrass and many small broadleaf weeds—specifically during turf establishment, overseeding, interseeding, and renovation. Designed for use on both cool- and warm-season turf, Rectangular helps reduce early weed competition so new turf can establish quickly and uniformly.
Rectangular offers exceptional flexibility, allowing applications up to 1 day before seeding or 7 days after turf emergence, making it usable up to 6 weeks sooner than many competing herbicides. Its optimized dual-active formulation of Carfentrazone-ethyl and Quinclorac provides rapid foliar activity plus sustained suppression to keep weeds from overtaking young turf.
Suitable for lawns, golf courses, sod farms, and athletic fields, Rectangular ensures a clean, healthy start for newly seeded turf while mixing easily as a dispersible granule. A nonionic surfactant (NIS) is recommended but not required for improved foliar uptake.
