BASF has submitted a proposed label for its dicamba product, Engenia, to the Environmental Protection Agency (EPA) for registration after the label was vacated earlier this year.

The proposed rules would reduce the concentration equivalent level of concern equivalent from 15 parts per billion to 3.4 parts per billion, reduce atrazine usage to a maximum of 2 pounds per acre per year, prohibit aerial spraying, and ban atrazine applications to saturated soils, as well as within 48 hours of forecasted heavy precipitation.

The U.S. Environmental Protection Agency recorded nearly 3,500 reports of off-target dicamba movement in 2021, despite stricter rules enacted in 2020.

The U.S. Environmental Protection Agency has agreed with companies and agriculture groups that additional time is needed to comment on proposed rule changes for atrazine.
