​​State-Specific Restrictions for Dicamba on Soybeans in 2020

The Illinois Department of Agriculture (IDOA) announced additional label restrictions for the 2020 growing season for the herbicide dicamba. After careful consideration, IDOA Director John Sullivan has determined the Department will be forwarding 24 (c) registration requests to the United States Environmental Protection Agency (USEPA) for Illinois specific labels for the use of dicamba on soybeans in 2020 requiring the following additional provisions:

 

  1. DO NOT apply this product 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 forecast are available at https://www.weather.gov.)

  2. DO NOT apply this product after June 20, 2020.

  3. Before making an application of this product, the applicator must consult the FieldWatch sensitive crop registry (https://www.fieldwatch.com) and comply with all associated record keeping label requirements.

  4. Maintain the label-specified downwind buffer between the last treated row and the nearest downfield edge of any Illinois Nature Preserves Commission site.

  5. It is best to apply product when the wind is blowing away from sensitive areas, which include but are not limited to bodies of water and non-residential, uncultivated areas that may harbor sensitive plant species.

“The number of off-target complaints received during the 2019 growing season rose dramatically, and the Department is taking action to reduce those numbers,” said John Sullivan, Director, IDOA. “These additional restrictions were reached after careful consideration with our Environmental Programs team at the Department, as well as input from stakeholders in the agriculture industry.”

In addition to these provisions’, applicators must follow the federal guidelines when it comes to applying dicamba, including taking an annual certified applicator training course.

The intent of these additional restrictions is to reduce the potential for off-target movement of this product, thereby reducing the potential for possible adverse impacts to dicamba-sensitive crops/areas. Dicamba is primarily used on soybeans to control post-emergence broadleaf weeds. The decision to pursue state-specific Special Local Needs (SLN) labels was made in response to the record number of misuse complaints the IDOA received during the past three years. 


Special Dicamba Training​

Label revisions for 2019 require specialized training for users as outlined in this section.

On October 31, 2018, USEPA issued revised labels for the three Dicamba-containing products that are labeled for use on soybeans:  Engenia (BASF), XtendiMax (Monsanto), and FeXapan (DuPont).  At this time, it is a violation of the Illinois Pesticide Act and the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) to apply any other Dicamba products in a post-emerge application to soybeans.

There are several significant changes in these product labels for use in crop year 2019, including:  

  • Two-year registration (until December 20, 2020); 
  • Only certified applicators may apply dicamba over the top (those working under the supervision of a certified applicator may no longer make applications); 
  • Prohibit over-the-top application of dicamba on soybeans 45 days after planting and on cotton 60 days after planting;
  • For cotton, limit the number of over-the-top applications from 4 to 2 (soybeans remain at 2 OTT applications);
  • Applications will be allowed only from 1 hour after sunrise to 2 hours before sunset;
  • In counties where endangered species may exist, the downwind buffer will remain at 110 feet and there will be a new 57-foot buffer around all other sides of the field to protect sensitive areas (the 110-foot downwind buffer applies to all applications, not just in counties where endangered species may exist);
  • Clarify training period for 2019 and beyond, ensuring consistency across all three products;
  • Enhanced tank clean-out instructions for the entire system;
  • Enhanced label to improve applicator awareness on the impact of low pH's on the potential volatility of dicamba;
  • Label clean up and consistency to improve compliance and enforceability;


If you plan to apply these products to soybeans in 2019, the Illinois Department of Agriculture will require all users of these products to adhere to all label requirements including completion of a training program that utilizes training materials developed by the registrants of the products, namely Bayer/Monsanto, BASF, or Corteva/DuPont.


Dicamba-specific training is required prior to applying these products in the 2019 growing season and each growing season thereafter.  If you received dicamba-specific training last year, you must still complete the training again in 2019.

If you received the required dicamba-specific training for the 2019 growing season prior to the implementation of the state-specific Special Local Needs labels for the three dicamba-containing products for use on soybeans, you are not required to re-take the training.


Training administered by a representative of one of the three registrants will be offered in a classroom setting. Online training will also be accepted.  Details of online training will be posted by registrants on their respective web sites:


Training Locations & Dates

The available classroom training dates and locations for Dicamba training through IFCA and IDOA are featured at https://ifca.com/IllinoisDicambaTraining.  The industry is working to make training opportunities available after the private applicator training and testing clinics for 2019. The aforementioned website will be updated with training dates and locations as they become available, so please visit it regularly and register to attend a session at your earliest convenience.   

Please go to the website and pre-register for these events so that the organizers of the training can ensure adequate seating and training materials.

Those who participate for the entire training class will receive a certificate of completion that can be utilized as proof of training for recordkeeping purposes.
