No Additional Dicamba Regulations for Hoosiers Beyond What’s on the Label

In a YouTube video sent out late Tuesday afternoon to Agribusiness Council of Indiana members, ACI President Amy Cornell said that the Office of Indiana State Chemist (OISC) will not put any additional restrictions on dicamba use beyond what is on the federal label as it is currently drafted. The OISC was considering a cut-off date of June 20, 2019 for dicamba usage, as well as a setback between a half-mile and a quarter-mile for crops that are sensitive or residential areas.

Cornell said that the OISC came to this conclusion after much discussion and collaboration between them and a dicamba working group, the Agribusiness Council of Indiana, and other ag organizations. She added her appreciation, saying, “Thank you to the Office of the Indiana State Chemist, the Pesticide Review Board, the Dicamba working group, ACI members and other agriculture organizations for working together to provide a sensible solution.”

The U.S. Environmental Protection Agency (EPA) announced that it is extending the registration of dicamba for two years for “over-the-top” use (application to growing plants) to control weeds in fields for cotton and soybean plants genetically engineered to resist dicamba back in November.

Dicamba registration decisions for 2019-2020 growing season

  • Two-year registration (until December 20, 2020)
  • Only certified applicators may apply dicamba over the top (those working under the supervision of a certified applicator may no longer make applications)
  • Prohibit over-the-top application of dicamba on soybeans 45 days after planting and cotton 60 days after planting
  • For cotton, limit the number of over-the-top applications from 4 to 2 (soybeans remain at 2 OTT applications)
  • Applications will be allowed only from 1 hour after sunrise to 2 hours before sunset
  • 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)
  • Clarify training period for 2019 and beyond, ensuring consistency across all three products
  • Enhanced tank clean out instructions for the entire system
  • Enhanced label to improve applicator awareness on the impact of low pH’s on the potential volatility of dicamba
  • Label clean up and consistency to improve compliance and enforceability
