While Palmer amaranth is garnering much of the attention, there are other resistant weed battles being fought in the region. According to Brian Jenks, a weed scientist at the NDSU North Central Research Extension Center, waterhemp is probably the bigger issue in eastern North Dakota.
“A couple other weeds we’re concerned about because of resistance are kochia and horseweed. We see kochia blowing across fields, spreading seeds and leaving trails,” says Jenks. “Another is narrowleaf hawksbeard in the western part of the state. It can easily blanket a field in just a year or two, resembling a canola field.”
Jenks spoke at the Wild World of Weeds Workshop in Fargo. Hear more of the conversation.
