More suspected Palmer amaranth plants found in North Dakota

September 10, 2018

BISMARCK, N.D. (AP) — More plants that are suspected to be the aggressive pigweed species Palmer amaranth have been found in McIntosh County.

The Agriculture Department says the plants were in fields near the one where Palmer amaranth was positively identified earlier this summer . It was the first time the weed had been found in North Dakota. The newly discovered plants are going through DNA analysis.

Palmer amaranth can grow as tall as 7 feet. It’s strong enough to stop combines and resist many herbicides.

The weed has devastated crops in other parts of the country. Purdue University research indicates a heavy infestation can cut soybean yields by as much as 79 percent and corn yields by up to 91 percent.

Agriculture Commissioner Doug Goehring is encouraging farmers to scout fields this harvest.
