EPA worked with pesticide manufacturers, farmers, state regulators, and other stakeholders to develop the following label changes for over-the-top use of dicamba on dicamba-tolerant cotton and soybeans through the 2020 growing season:

• Only certified applicators may apply dicamba over the top (those working under the supervision of a certified applicator may no longer make applications)
• In counties where endangered species may exist, the downwind buffer will remain at 110 feet and there will be a new 57-foot buffer around the other sides of the field (the 110-foot downwind buffer applies to all applications, not just in counties where endangered species may exist)
• Enhanced label to improve applicator awareness on the impact of low pH’s on the potential volatility of dicamba
• Prohibit over-the-top application of dicamba on soybeans 45 days after planting after planting
• Applications will be allowed only from 1 hour after sunrise to 2 hours before sunset
• Enhanced tank clean-out instructions for the entire system
• Label clean up and consistency to improve compliance and enforceability
• Clarify training period for 2019 and beyond, ensuring consistency across all three products
