Should I be concerned about Palmer amaranth in my prairie strips?
Yes. Palmer amaranth is a noxious and aggressive weed that is now widely distributed in Iowa. It is difficult to control and can strongly affect crop production. It was unintentionally brought into the state on agricultural equipment and within seed mixes for native plantings as well as in cotton seed and gin trash used in dairy rations. Additionally, some seeds of this species could have come in via hay and/or livestock bedding. Read more about FAQ: Should I be concerned about Palmer amaranth?
