Abstract

Many people are aware of the problems Palmer amaranth is causing farmers in the mid-south and southeast United States. Palmer amaranth is a close relative to Iowa’s number one weed problem – waterhemp. Like waterhemp, Palmer amaranth is a species with a propensity to evolve herbicide resistance. Glyphosate resistant Palmer amaranth devastated the cotton industry, which has fewer chemical options than available in corn and soybean. This article will describe Palmer amaranth and the risk of it appearing in Iowa.
