PBI-Gordon announced that Arkon Herbicide Liquid has been approved for use in most U.S. states (excluding California and Alaska). The EPA previously approved federal registration for the herbicide.

Arkon is labeled for use on established cool- and warm-season turfgrass species across a wide variety of use sites, including golf course greens, fairways and roughs, residential and commercial lawns, sports facilities, and sod farms. It will be available for sale nationwide in 2024 and will be included in PBI-Gordon’s Green Dividends Early Order Program in fall 2023.

Utilizing the innovative and proprietary active ingredient Pyrimisulfan, Arkon provides post-emergent control of sedges (yellow, purple and annual), kyllinga (green false green, cockscomb and annual), dollarweed, chickweed, henbit and many other labeled broadleaf weeds. Additionally, research has shown that the liquid herbicide reduces the number and viability of nutsedge tubers.

Part of PBI-Gordon’s “Powered by Vexis” family of herbicide products, Arkon is a low-rate, non-phenoxy product. The application rate is as follows:

In addition to many years of proprietary and independent testing before launching the herbicide, PBI-Gordon provided demonstration product Arkon to more than 460 end users earlier in 2023 — which gave them insider access to the product before it hits the market. The participants in the program represented a wide range of turfgrass professionals from across the country.

“The impact of our Arkon demo program went far beyond the experience of the participants,” said Jason Manz, PBI-Gordon vice president of strategic marketing and business development. “The excitement and anticipation it built within the industry have positioned Arkon as the ‘go-to’ post-emergent nutsedge and kyllinga product in 2024.”

Arkon’s active ingredient Pyrimisulfan is the result of an exclusive partnership between PBI-Gordon Corporation, Kumiai Chemical Industry Co., Ltd., and their US subsidiary K-I Chemical U.S.A Inc.
