The EPA announced it has approved label amendments that further restrict the use of over-the-top dicamba in Iowa and Minnesota.
View EPA Site for Dicamba

The revised labeling prohibits over-the-top dicamba application:
  • On dicamba-tolerant crops after June 12 in Iowa

Also, the EPA is now requiring that all growers (not just growers in Iowa and Minnesota) using XtendiMax must check:
within 7 days of application in case their state has made any local label updates. Growers using XtendiMax must have all relevant labeling in their possession at the time of application.

Dicamba training is now part of the EPA label. Training from any of the companies below qualifies as the required training for this restricted use pesticide. Please direct any questions about product labeling or training requirements to the Iowa Department of Agriculture and Land Stewardship Pesticide Bureau.

Online training from one provider qualifies as dicamba/auxin training for all dicamba-based products.
