SPRINGFIELD, Illinois – The administrative rules proposed by the Illinois Department of Agriculture (IDOA) for the use of dicamba on soybeans have been published in the Illinois Registry today. The proposed restrictions for the use of dicamba on soybeans are the same restrictions that were required in 2021. The publication of the rules in the Illinois Registry the first notice period begins, during which the IDOA must accept public comments.

In October 2020, the USEPA announced that it had renewed Federal Insecticides, Fungicides, and Rodenticides (FIFRA) registrations for three dicamba pesticides for the 2021-2025 growing seasons. Contrary to past practice, the USEPA has stated that the only way for states to add safety restrictions to these products is section 24 (a) of FIFRA, which allows a state to add restrictions by through its rule-making process.

In February 2021, the IDOA filed emergency rules detailing additional restrictions on the application of dicamba to soybeans for the 2021 growing season. Since the Illinois Administrative Procedure Act prohibits agencies State to adopt emergency rules more than once in a 24-month period, the department is now required to continue the permanent rule-making process.

In addition to the requirements of federally approved labels, the rules proposed by the IDOA include the following requirements for the use of pesticides containing dicamba on soybeans:

  • A pesticide containing dicamba should not be applied to soybeans if the air temperature in the field at the time of application is above 85 degrees Fahrenheit or if the high temperature predicted by the National Weather Service for the available location. closest to the day of application exceeds 85 degrees Fahrenheit. Forecasts from the local national weather service are available at https://www.meteo.gov.
  • Application to soybeans of a pesticide containing dicamba should not be made after June 20 of each year.
  • Before applying a pesticide containing dicamba to soybeans, the applicator should consult the FieldWatch Susceptible Crop Record (https://www.fieldwatch.com) and comply with all associated record keeping and tagging requirements.
  • Application to soybeans of a pesticide containing dicamba should not be made if the wind is blowing to: any Illinois Nature Preserves Commission site adjacent to the scope; or an adjacent residential area.

“The number of untargeted complaints received over the past two growing seasons has declined significantly since the implementation of the changes to the label restrictions,” said Jerry Costello II, Director, IDOA. “The decision to keep these rules in place was taken after assessing several factors, including the reduction in cases of pesticide abuse involving the use of dicamba on soybeans from 2019 to 2020.”

In addition to these provisions, applicators should follow federal guidelines when applying dicamba, including completing annual dicamba-specific training and being a certified applicator.

The intention of these additional restrictions is to reduce the potential for off-target movement of this product, thereby reducing the potential for possible negative impacts on crops / areas susceptible to dicamba. Dicamba is primarily used on soybeans for postemergence broadleaf weed control.
