One of the label requirements for the dicamba products labeled for over-the-top use in soybean (Xtendimax, Tavium, Engenia) is that applicators must complete a special dicamba training annually.
If you need to complete this training, go to the Agribusiness Association of Iowa website, and you will find links to the companies’ websites with their training information. Note that the links are found under the heading “Product Labels and Information, see image below.
Training from one company qualifies as dicamba/auxin training for all dicamba-based products.
As a reminder, any person responsible for mixing, loading, applying, or cleaning dicamba application equipment must be a certified private pesticide applicator or commercial pesticide applicator in the state of Iowa and must attend a dicamba training prior to handling the product each growing season. Iowa certified handlers and other employees cannot handle these products.
Additionally, please make sure you read over the entire label for whichever dicamba product you will use prior to using it this growing season. As of February 16, 2022, Iowa doesn’t have any additional label requirements for these products. This could potentially change, so it is recommended to double check prior to spraying to see if Iowa has any additional label requirements.
