Abstract

Nine preplant herbicides were tested for the control of glyphosate-resistant (GR) Canada fleabane in corn. At eight weeks after treatment (WAT), the herbicides that resulted in the greatest control and least amount of density and biomass of GR Canada fleabane were dicamba/atrazine (99%), mesotrione atrazine (97%), saflufenacil/dimethenamid-p (97%), and dicamba (94%).
