Two possible cases of Palmer amaranth are being investigated in North Dakota. A sample submitted to the University of Illinois plant clinic has positively identified it as Palmer amaranth. State officials have now ordered extensive DNA analysis to confirm that finding. Palmer amaranth is a type of pigweed that has devastated crops in the South. This weed has been found in South Dakota and Minnesota, but if confirmed, this discovery would be a first for North Dakota. The North Dakota Department of Agriculture has an action plan in place. If confirmed the weeds will be hand-pulled and destroyed and the site would be monitored for a minimum of three years.
