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.

2019 Illinois Dicamba Use 

For 2019, 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 2019:

Due to the extraordinarily wet weather seen in the state this spring planting season, the Illinois Department of Agriculture (IDOA) announced it will extend the application date the herbicide dicamba can be applied on soybeans in Illinois for the 2019 growing season until July 15.

The additional restrictions on dicamba set in February will remain in effect and are as follows:

  1. Prohibiting application when the wind is blowing toward adjacent residential areas.
  2. Required consultation of the FieldWatch sensitive crop registry before application, as well as compliance with all associated record keeping label requirements.
  3. Maintaining the label-specified downwind buffer between the last treated row and the nearest downfield edge of any Illinois Nature Preserves Commission site.
  4. Recommendation 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.

Those who planted before June 1, 2019 will remain subject to the original dicamba application cutoff date, which was planting date plus 45 days. Illinois producers who planted soybeans after June 1, 2019 will be required to adhere to the newly extended July 15th dicamba application cutoff date.

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 13, 2017, U. S. EPA issued new requirements for the application of dicamba products to further minimize the potential for drift to damage neighboring crops from the use of dicamba formulations used to control weeds in genetically modified cotton and soybeans. 

New requirements for the use of dicamba "over the top" applications will allow farmers to make informed choices for seed purchases for the 2018 growing season.

  • Under the 2018 new formulations of dicamba label changes:
    • Only a certified applicator can apply the product, or someone who is directly supervised by them. 
    • The applicator must receive specialized training in applying the product. This can be technical training offered by the state, or if that is not available then they can receive training from the tech companies.
    • A producer must record the conditions when applying the product, including wind speed, application rate, and the number of acres. A bill of sale must also be kept as a record.
    • The herbicide can only be applied if the maximum wind speed is 10 mph or less and is only allowed from sunrise to sunset.
  • Farmers/applicators need to reduce drift and volatilization according to the product label by adhering to specific boom height, sprayer speed and nozzle type.  
  • Anyone employed to apply general use pesticides must have a license from the Illinois Department of Agriculture. 
  • Given the potential damage from off-target movement of dicamba to non-tolerant soybeans and other sensitive crops, all farmers need to take the following steps:
  • Identify the proximity of non-tolerant soybeans and other sensitive crops, and
  • Prioritize communication with neighbors before planting; during planting, spraying, and scouting; and after harvest.
