PBI-Gordon Arkon Herbicide Liquid, 32 fl oz (1 Quart) – Professional Post-Emergent Sedge & Kyllinga Control – Reduces Nutsedge Tuber Viability – Powered by Vexis Technology – Safe for All Turf Types

PBI-Gordon Arkon Herbicide Liquid represents a breakthrough in professional turf management, offering an innovative solution for the most difficult sedge and kyllinga infestations. Powered by advanced Vexis Technology, this liquid formulation provides exceptional post-emergence control of listed broadleaf weeds and sedges while remaining safe for both cool- and warm-season turfgrass. Unlike traditional herbicides that only address surface growth, Arkon is scientifically proven to reduce the number and viability of underground nutsedge tubers and false-green kyllinga rhizomes. In rigorous university research trials, Arkon demonstrated a 96% to 99% reduction in purple nutsedge tuber viability, effectively stopping the next generation of weeds before they can emerge. This comprehensive control extends to yellow, purple, and annual nutsedge; green, false green, cockscomb, and annual kyllinga; and problematic broadleaf weeds such as dollarweed, chickweed, henbit, and hairy bittercress. Engineered for versatility and precision, Arkon is labeled for use on high-value sites including golf course greens, tees, and fairways, as well as residential lawns, athletic fields, and sod farms . It is safe for a wide range of grass species, including Kentucky bluegrass, fine and tall fescues, perennial ryegrass, bermudagrass, and zoysiagrass. This 32 fl. oz. quart bottle features a built-in measuring chamber, ensuring accurate dosing and easy tank-mixing for consistent, professional-grade results every time. By targeting the source of the problem underground, Arkon delivers long-term population reduction rather than just a temporary fix, making it the premier choice for maintaining pristine, weed-free turf.
