Herbicide for use in potatoes, hemp and other crops obtains federal registration

A herbicide for use in onions, potatoes and other crops to help control annual grasses and key broadleaf weeds before emergence has been federally registered.

Sonalan HFP Herbicide’s registration also marks the first U.S. tolerance of a herbicide for use in hemp, according to a release from Gowan Co. LLC.
The herbicide is also for use in stevia, dry beans, dry peas, dry-shelled beans except soybeans and some dry-shelled peas, in addition to peanuts and specified oilseed crops.

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, according to the release.

“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, Gowan 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.”

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