Get the Real Thing
In recent years, we have seen an increased substitution of corn gluten feed and distillers grain for real corn gluten meal. This is often sold at feed stores or local garden stores. These products are not the real thing. They are not corn gluten meal and they will not work. If you want real corn gluten meal, be sure that you are buying from a licensed dealer or someone who is carrying product from a licensed dealer. For a list of these licensed dealers, go to http://www.techtransfer.iastate.edu/en/for_industry/technology_search/cgm_licensees.cfm.
