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.”

New Study on Weeds and Yield Loss in Dry Beans

The Weed Science Society of America completed a study on the impact of weed control on dry beans grown in the U.S. and Canada. Dry bean data was collected for a ten year period between 2007 and 2016. Researchers found that 71 percent of the crop would be lost if weeds were left uncontrolled, resulting in a cost to growers of about $722 million annually. The most troublesome weeds include common lambsquarters and kochia, as well as species of pigweed and nightshade.
