KANSAS CITY, MO – Spray drift issues led to lawsuits a few years ago, as some producers of dicamba-tolerant crops were sued by other producers because of damage to their crops.
To keep the technology available for corn and soybean farmers, regulations were introduced at the federal and state levels aimed at limiting the application window for dicamba thereby reducing the potential of damage to non-tolerant crops.
In 2019, federal restrictions were placed on the application of dicamba in cotton fields from one hour after sunrise until two hours before sunset, with limited applications up to 60 days after planting.
Some states imposed additional restrictions or extensions to the federal mandate, which allowed for application further into the growing season.
Though some of the deadlines varied from state to state, in 2020 the Environmental Protection Agency (EPA) instituted a single nationwide cut-off date of July 30 for all applications of dicamba by farmers in the field.
