In September 2016, Palmer amaranth (Amaranthus palmeri) was initially discovered and confirmed in Minnesota. Efforts to eradicate this weed are critical to Minnesota’s commodity crop producers.

Palmer amaranth is on the Minnesota Noxious Weed List as an “Eradicate” weed. This legal status means the plant must be destroyed and that no transportation, propagation or sale of this plant species is allowed.

Report possible infestations to the Minnesota Department of Agriculture (MDA) at https://www.mda.state.mn.us/reportapest. You can use their Report a Pest online reporting form, email them at reportapest@state.mn.us, or call 1-888-545-6684.
