Details on Dicamba Registrations and Label Changes

USEPA indicated that they do not expect there to be any changes made to the federal dicamba label for over-the-top applications to soybeans prior to the 2022 growing season.  Any additional restrictions to the label will once again fall to the state level.  IDOA stated that rules filed for additional dicamba restrictions for the 2022 growing season are the exact same restrictions required for the 2021 season.  Continue reading below for more information on the recent USEPA and IDOA updates.
Federal USEPA Update
On December 21st, 2021, the USEPA provided a summary of dicamba-related incident reports from the 2021 growing season.  Some highlights from the summary provided below:
Given the new information from the 2021 growing season, EPA is reviewing whether over-the-top dicamba can be used in a manner that does not pose unreasonable risks to non-target crops and other plants, or to listed species and their designated critical habitats. EPA is also evaluating all of its options for addressing future dicamba-related incidents.
EPA is committed to helping states address issues related to incidents in their jurisdictions. If a state wishes to further restrict or narrow the over-the-top uses of dicamba, the Agency will work with them to support their goals. Additionally, due to the extent and severity of reported incidents from the 2021 growing season, EPA is unlikely to approve section 24(c) requests under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to register additional uses of federally registered over-the-top dicamba products to meet special local needs.
Registrants can propose voluntary measures to amend their labels or cancel specific products or uses.  
If EPA determines, following consideration of such a proposal, that such measures would address unreasonable adverse effects associated with the product or use, the Agency commits to conducting a public comment period prior to the adoption of any proposed decision designed to address the extent and severity of these incidents. In the absence of a voluntary request to cancel the product(s), it is unlikely that this process could occur and be fully implemented before the 2022 growing season. For more information see: Voluntary Cancellation of a Pesticide Product or Use.
If EPA determines that it is necessary to initiate cancellation of a registration for a pesticide, the following process is used: Pesticide Cancellation Under EPA's Own Initiative.

State IDOA Update
On December 3rd, 2021, Illinois Department of Agriculture (IDOA) filed rules with the Illinois Secretary of State on dicamba application to soybeans. The restrictions for dicamba use on soybeans filed by IDOA are the same restrictions required in 2021. The rules were published in the Secretary of State's Illinois Register December 17th, 2021.  IDOA provided a press release detailing the proposed rules.  The additional restirctions for dicamba application on soybeans in Illinois are listed below:
  • A pesticide containing dicamba shall not be applied on soybeans if the air temperature at the field at the time of application is over 85 degrees Fahrenheit or if the National Weather Service’s forecasted high temperature for the nearest available location for the day of application exceeds 85 degrees Fahrenheit. Local National Weather Service forecasts are available at
  • Application on soybeans of a pesticide containing dicamba shall not be made after June 20 of each year.
  • Before applying a pesticide containing dicamba on soybeans, the applicator shall consult the FieldWatch sensitive crop registry ( and comply with all associated recordkeeping and label requirements.
  • Application on soybeans of a pesticide containing dicamba shall not be made if the wind is blowing toward: any Illinois Nature Preserves Commission site that is adjacent to the field of application; or an adjacent residential area.
