There is another confirmed case of Palmer amaranth in North Dakota. The weed was found in Benson County. North Dakota Department of Agriculture plant protection officer Charles Elhard tells the Red River Farm Network there are now three confirmed cases of Palmer in the state; Benson County, Foster County and McIntosh County. “There’s two more samples at the labs we have not gotten back yet.” Elhard says the focus is on education. Palmer amaranth is a competitive and aggressive pigweed that can significantly reduce the yield in corn and soybeans. As of now, Palmer amaranth is not on North Dakota’s noxious weed list.
