Soybean growers in Illinois will need to follow stricter regulations when applying dicamba in 2020.

On Oct 11., the state agriculture department announced it is seeking additional label instructions from the Environmental Protection Agency (EPA) when it comes to spraying dicamba on soybeans.

Pending EPA approval, producers must comply with the following provisions in addition to existing federal regulations.

  1. Do not apply this product if the air temperature in the field at the time of application is over 85 F or if the National Weather Service’s forecasted high temperature for the nearest available location for the day of application exceeds 85 F.

  2. Do not apply this product after June 20, 2020.

Illinois had 246 registered complaints in 2017, 330 complaints in 2018 and 724 complaints in 2019.
