The information below provides general guidance related to dicamba products registered for over-the-top use in dicamba-tolerant soybeans. Applicators must follow all federal label directions and Illinois-specific requirements. 

Which dicamba products are labeled for over-the-top use in dicamba-tolerant soybeans?

The following dicamba products are registered by EPA for over-the-top use in dicamba-tolerant soybeans:

• Engenia Herbicide

• Stryax Herbicide

Applicators should consult the current federal label for each product for complete directions, restrictions, and application requirements.

Where can I find the federal labels for these dicamba products?

Federal labels for Engenia, Stryax, and Tavium are available on the IFCA Labels, Forms and Other Resources page and through product manufacturer websites or the EPA pesticide label database.

Applicators should ensure they are using the current federal label prior to application.

Is special training required to apply dicamba over the top of soybeans?

Yes. The federal labels require annual dicamba-specific training for applicators using these products.

Training is offered by product registrants and other approved providers. Applicators must complete one approved dicamba training program each year before applying these products.

Training resources are available on the IFCA Labels, Forms and Other Resources page.

Do applicators need to check EPA Bulletins Live! Two before applying dicamba?

The federal labels direct applicators to check EPA’s Bulletins Live! Two system to determine whether endangered species protections apply to the application site.

If a bulletin exists for the application area, applicators must follow any additional requirements listed in the bulletin.
