Abstract

Most people are aware of the concerns regarding Palmer amaranth moving into Iowa. As discussed in an earlier article, distinguishing Palmer amaranth from waterhemp can be difficult in the vegetative stage. The majority of Amaranthusplants should currently be in the reproductive stage, greatly simplifying identification. Palmer amaranth produces long terminal branches on its inflorescences, capable of reaching lengths of three feet. The flowers of female Palmer amaranth plants have sharp bracts that are painful to the touch.
