Most people are aware of the multiple findings of Palmer amaranth across Iowa this month. Palmer amaranth has been identified both in crop fields and in conservation plantings using native seed mixes. Early detection is essential in order to prevent the new weed from getting permanently established in fields where it has been introduced. A new bulletin on identification (CROP 3105) will help people new to Palmer amaranth differentiate it from waterhemp and the other weedy pigweeds found in Iowa.
