Research Interests

My research has been in weed interference. Studies on the zone of influence of two broadleaf weeds in soybeans have been completed. These studies have determined the threshold values for jimsonweed and cocklebur in soybeans grown in Indiana. I have recently started research to determine the effect of foxtail on corn. These studies are part of the NC-202 project that is being conducted in several north central states.
