NDSU Extension is asking farmers to scout for Palmer Amaranth in fields. The noxious weed can reduce yield up to 91 percent in corn and 79 percent in soybeans. Palmer amaranth is not yet in North Dakota. The weed is in Minnesota, South Dakota and Iowa. Palmer amaranth is a pigweed and can be identified by scouting fields for something that doesn’t look right. The seedlings have egg-shaped leaves, the stems and leaves have few or no hairs and the leaf stem can be as long or longer than the leaf blade.
