Brief Project Summary:

A field site in west Kentucky containing a mixed population of both Palmer amaranth and waterhemp was identified in 2015 that has displayed resistance to both glyphosate and postemergence applications of fomesafen [Flexstar], a prophyrinogen oxidase inhibitor (PPO) herbicide. This field site is unique since mixed populations of Palmer amaranth and waterhemp in the same field are not common. Field and greenhouse trials along with laboratory analysis will be used to investigate the characteristics of this population and to evaluate alternative control strategies that can be used to effectively manage these weeds. The focus of the field study is to evaluate soil-residual and postemergence herbicide...
