Replanting Dicamba Soybean

Replanting soybean fields or areas of fields likely will occur after soybean stand loss to recent cold temperatures or saturated soil conditions.  The following are general reminders about dicamba application timings and restrictions for Illinois soybean.

  • Air temperature restriction: do not apply approved dicamba-containing products if the air temperature in the field at the time of applications is greater than 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.  Applicators must consult the Local National Weather Service forecast for your field’s zip code, available at https://www.weather.gov.
  • Do not apply approved dicamba-containing products after June 20.
  • Do not apply approved dicamba-containing products more than 45 days after planting.

The calendar and timing restrictions deserve some consideration if replanting becomes necessary.  If a portion or portions of a field are replanted, use the original planting date when determining the 45-day deadline for the earlier planted areas and clearly delineate and document the replant areas separately. And remember, any replant areas will reach the June 20 application deadline before 45 days after planting.  Dicamba can provide a limited amount of residual weed control, but applying an approved soil-residual herbicide with dicamba can help extend weed control after application.
