Palmer Amaranth Now Identified in At Least Nine Iowa Counties

Palmer amaranth is an invasive weed that is native to the southwestern United States. Over the last three years, however, the weed has made its way into Iowa and has been identified in at least nine counties, most recently in Madison, Clayton, Washington, and Crawford counties.

Palmer amaranth is related to waterhemp, a common weed found across Iowa. In addition to traditional weedy traits, the characteristic that makes those two weeds unique, and hard to manage, is their ability to evolve resistance to herbicides.

Both Palmer amaranth and waterhemp are adapted to a production system that relies on herbicides. Waterhemp is a relatively non-competitive weed so many farmers have learned to accept lower levels of weed control. If Palmer amaranth spreads across the state and farmers try to manage it like they do waterhemp, it will have a huge negative economic impact.
