Two Palmer Findings in Two Weeks

/in , /by
Palmer amaranth has been confirmed in Stutsman County, North Dakota. A county weed officer noticed some suspect plants in a field and notified the landowner. One week prior, the noxious weed, along with large amounts of waterhemp, were identified in a Benson County, North Dakota soybean field. It’s not exactly known how the weed got there, but the Benson County Extension agent thinks the weeds may have been there for many years.
 
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 and multiple modes of action. It is a highly invasive weed that can dramatically cut crop yields.

Potential Palmer Findings in North Dakota

New potential cases of Palmer amaranth are being investigated North Dakota. NDSU Extension Weed Scientist Joe Ikley looked at two different fields in the last two weeks, one in Benson County and the other in Nelson County. “I walked fields and found plants that looked like Palmer amaranth. Samples have been collected and sent to the lab to confirm if it’s Palmer,” says Ikley. “We want to confirm before we put an action plan in place because it’s a noxious weed.”
