Dicamba Training Requirements

 

Certain dicamba formulations can be used to control weeds in cotton and soybean plants that are genetically engineered to tolerate dicamba.

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

The registration for all dicamba products will automatically expire on December 20, 2020, unless EPA further extends it.
