In February, the USEPA announced that three dicamba-containing products were approved for over-the-top (OTT) applications in soybean fields in 2026, with validity for only two years pending further review. Those three products are: Stryax (Bayer), Engenia (BASF), and Tavium (Syngenta). The new national restrictions are as follows:
- a maximum of two applications of 0.5 pounds of dicamba per acre may be made annually, totaling a maximum of 1.0 pound of all dicamba products annually
- 40 oz/A of approved Volatility Agent must be added to every application
- Growers must achieve 3 runoff/mitigation points from EPA's certified conservation practices menu
- Only certified applicators may use this product.
- Certified applicators must complete annual training specific to OTT dicamba use
- Do not apply product if sensitive crops or certain plants are in an adjacent downwind field.
- Apply between one hour after sunrise and two hours before sunset when wind speed at boom height is between 3 and 10 mph.
- Do not apply during temperature inversion.
In addition to the USEPA label restrictions, the following Illinois label restrictions apply:
- no OTT dicamba application when the temperature at the time of the application is over 85 degrees F, or if the National Weather Service’s forecasted high temperature for the nearest available location for the day of application exceeds 85 degrees F
- no applications made after June 20
- before applying a pesticide containing dicamba on soybeans, the applicator shall consult the FieldWatch sensitive crop registry and comply with all associated recordkeeping and label requirements.
