History: Setaria faberi was introduced into the US accidentally as a seed contaminant in the 1920s and is more commonly found in rural areas than in urban places. It is now considered naturalized in much of the US, Canada and Mexico. There is evidence that Setaria faberi produces secondary alleopathic chemicals that inhibit the growth of nearby plants.
