Palmer amaranth (Amaranthus palmeri), an aggressive pigweed species similar in appearance to waterhemp, has been positively identified for the first time in North Dakota in McIntosh County. Palmer amaranth is native to the southwestern U.S. but was accidentally introduced to other areas and has devastated crops in the South and Midwest. It had not been identified in North Dakota until now. The public is urged to work with local weed officers, extension agents and other experts to identify and report suspect plants. More information on Palmer amaranth and other noxious and invasive weeds is available here. To report a suspect plant, contact the North Dakota Department of Agriculture at 701-328-2250 or North Dakota State University Extension at 701-231-8157 or 701-857-7677.
