According to a recent State Federal Insecticide Fungicide and Rodenticide Act Issues Research and Evaluation Group (SIFIREG) Dicamba Work Group guidance document and the Iowa Department of Agriculture and Land Stewardship Pesticide Bureau, only certified applicators can mix and handle the following dicamba products:

  • XtendiMax® with VaporGrip® Technology (EPA Reg. No. 524-617, Bayer)
  • Engenia® (EPA Reg. No. 7969-345, BASF)
  • FeXapan® with VaporGrip® Technology (EPA Reg. No. 352-913, Corteva)
  • Tavium® plus VaporGrip® Technology (EPA Reg. No. 100-1623, Syngenta)

Anyone who is responsible for any part of the use and application process, which includes mixing, loading, application, or cleaning dicamba application equipment, must be a certified and licensed private pesticide applicator or a commercial pesticide applicator and must attend a label-required dicamba training. Iowans certified in the Handlers category and other mixing and loading employees cannot handle these products even if they attend the required dicamba training.
