North Dakota advises public to look for Palmer amaranth
Staff Writer |
The North Dakota Department of Agriculture (NDDA) is advising the public to be aware of and learn to identify Palmer amaranth (Amaranthus palmeri), a pigweed species that is similar in appearance to waterhemp and has the potential to be devastating to North Dakota agriculture.

“We have been actively monitoring and investigating suspect plants over the past couple of years, but have not yet identified Palmer amaranth in North Dakota. It has been found in South Dakota, Iowa and Minnesota in recent years,” Agriculture Commissioner Doug Goehring said.
“Early detection will be the key to effectively eradicate or manage this weed if found in the state.”
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 is a prolific seed producer that can emerge throughout the growing season.
It grows rapidly at 2-3 inches per day in optimum conditions and is prone to herbicide resistance. It is a highly invasive weed that can dramatically cut crop yields.
The public is urged to work with local weed officers, extension agents and other experts to identify and report suspect plants. Palmer amaranth may spread through multiple channels, including: contaminated seed mixes; equipment and machinery movement; animal agriculture feed and bedding; and wild birds.
NDDA recommends that anyone planting a seed mix on any scale, especially those targeting pollinator or wildlife conservation, ensure they are using reputable sources for seed, are aware of where the seed was originally sourced from, know what seeds are in the mix and monitor for unwanted species. ■
