These tank-mix partners have been approved for use with FeXapan™ herbicide on Xtend® crops.

Stay up to date on tank-mix partners approved for use with FeXapan herbicide.  Use only approved tank-mix partners with FeXapan plus VaporGrip Technology.

Current FeXapan™ plus VaporGrip™ Technology supplemental labels for Xtend® soybeans and XtendFlex® cotton restrict tank mix use. FeXapan™ plus VaporGrip™ Technology may only be tank-mixed with products that have been tested and found not to adversely affect offsite movement potential of FeXapan™ plus VaporGrip™ Technology.

Approved tank-mix partners for DuPont™ FeXapan™ will be posted here as they are announced.

While tank mixes with a labeled partner are permitted on the FeXapan™ Section 3 label, an applicator must wait 28 days after 1 inch of rainfall or irrigation accumulates after applying FeXapan™ at 22 fluid ounces per acre before planting soybeans, including Xtend® soybeans. If planting Xtend® soybeans will occur before 28 days elapses, FeXapan™ must be applied alone.

Check this website no more than 7 days before application to determine which tank-mix partners are approved for use with FeXapan™ on Xtend® soybeans or XtendFlex® cotton. If a product brand is not listed, do not tank-mix it with FeXapan™.

Follow these guidelines when preparing to apply FeXapan™ plus VaporGrip™ Technology:

  • Do not use ammonium sulfate (AMS), AMS-containing products or UAN products in a tank mix with FeXapan™ herbicide plus VaporGrip™ Technology.
  • Apply a minimum of 10 gallons of spray solution per acre to ensure proper spray coverage.
  • Review other tank-mix information and stewardship guidelines to ensure effective weed control and to minimize risk of off-target herbicide movement.
