Dicamba Facts image

EPA has approved new dicamba labels intended for over-the-top (OTT) use on dicamba-tolerant (DT) soybeans and cotton. XtendiMax with VaporGrip Technology, EPA Reg. No. 264-1210; Engenia Herbicide, EPA Reg. No. 7969-472; and Tavium Plus VaporGrip Technology, EPA Reg. No. 100-1623, registrations will expire in 2025.

Some of the new requirements to the three new dicamba labels include:

  • Requiring an approved pH-buffering agent (also called a Volatility Reduction Agent or VRA) be tank mixed with OTT dicamba products prior to all applications to control volatility.
  • Requiring a downwind buffer of 240 feet and 310 feet in areas where listed endangered species are located.
  • Prohibiting OTT application of dicamba on soybeans after June 30 and cotton after July 30.
  • Simplifying the label and use directions so that growers can more easily determine when and how to properly apply dicamba.

Applicators should use these three products in accordance with label directions.
