Gowan receives federal herbicide registration for onions, potatoes

Gowan Co. L.L.C. has received federal registration of Sonalan HFP Herbicide for use in onions, potatoes and other crops.

The herbicide is okayed for use in onion subgroup 3-07A, hemp and stevia, and expansion from dry beans, dry peas and potatoes to crop groups; dry-shelled beans, except soybeans, crop subgroup 6-22E, dry-shelled pea crop subgroup 6-22F; and vegetable, tuberous and corm, crop subgroup 1C, according to a news release.

With federal registration in hand, labels have been sent for approval to all states where Sonalan HFP is registered.

“This effort included extensive trial work with private cooperators and universities and IR-4’s work in hemp, stevia, and crop group expansion,” Gowan officials said in the release. “This registration also marks the first U.S. tolerance of a herbicide for use in hemp.”

Sonalan HFP Herbicide is a FRAC Group 3 DNA herbicide containing ethalfluralin in a liquid EC formulation. It is tank-mix compatible with most pre-emergence herbicides for expanded control of annual grasses and key broadleaf weeds before emergence, according to the release. Ethalfluralin has been used for pre-emergence weed control in the industry for decades.

“Federal registration of Sonalan HFP for onions, hemp, and stevia illustrates Gowan’s commitment to bringing our customers effective products that improve their options and maintain a more sustainable business,” Ken Reh, product manager, said in the release. “With Sonalan HFP, growers will benefit from extended weed control, minimizing competition for water and nutrients, allowing the crop to yield to its maximum potential. In addition, Sonalan HFP is an excellent product for herbicide resistance management programs.”
