Abstract

S-triazine resistance in giant foxtail (Setaria faberi Herrm.) has been reported previously, but not in the midwestern U.S. corn belt or Iowa. A study was conducted using a chlorophyll fluorescence assay to confirm the presence of resistance in one S. faberi population in Iowa. Variable chlorophyll fluorescence assays confirmed that a population of this species with this type of resistance exists in Iowa. This is the first report of s-triazine resistance in S. faberi, and the fourth species with this type of herbicide resistance, found in an Iowa agroecosystem.
