Dicamba Resources

Dicamba Technology Demands Multiple Levels of Stewardship

Everyone involved with production agriculture in Illinois has a critical role to play in the proper stewardship of new products, such as dicamba-based herbicides, including strict adherence to all label guidelines. 

ISA continues to work with industry partners to inform growers about specific requirements related to dicamba use in Illinois.

2020 Illinois Dicamba Use 

For 2020, anyone who purchases or applies any dicamba product must be licensed by the State of Illinois as either private or commercial applicators. 

Online venues listed below are now approved in Illinois for required dicamba certification:

You must register for the online training. The online training will require that you go through the materials and be tested at the end of the module. Upon completion of the knowledge test, you will receive a certificate of completion of the training.

Responsible use of dicamba for 2020:

From Illinois Department of Agriculture: 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.

Be sure to check the manufacturer sites for the latest information on proper use of the three options of dicamba formulations—Monsanto's XtendiMax®, DuPont's FeXapan™ and BASF's Engenia®.

Additional Information:

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;
