Arkon Herbicide, PBI Gordon

Arkon Herbicide Liquid delivers post-emergence control of sedges and kyllingas, and listed broadleaf weeds on cool and warm-season turfgrass across a wide variety of use sites. And Arkon is proven to reduce the number and viability of nutsedge tubers.

What Arkon application rate should I use? How many applications?

• Arkon can be applied at 1.2 to 1.7 fl. oz. per 1,000 sq. ft. (3.4 to 4.7 pt. per acre).
• The maximum annual use rate is 2.5 fl. oz. per 1,000 sq. ft. (7 pt. per acre, per year).
• For hard to control weeds, consider making 2 applications at the 1.2 fl. oz. per 1,000 sq. ft. rate at least 30 days apart.

- Purple and yellow nutsedge and false-green kyllinga are problematic weeds plaguing quality turfgrass stands. Arkon Herbicide Liquid is labeled for purple and yellow nutsedge and false-green kyllinga control in cool- and warm-season turfgrasses. Hundreds of field efficacy research trials have demonstrated excellent long-term control of these weeds, and a better understanding of the residual control mechanisms was warranted. Research was conducted by the University of Georgia and Rutgers University to assess the effect of Arkon on purple and yellow nutsedge tuber reduction and viability as well as regrowth from false-green kyllinga rhizomes.
