New EPA Labels for Dicamba used on DR Soybeans

By now, most are aware that EPA approved new labels for the dicamba products used on dicamba-resistant (DR) soybeans. Major changes to the dicamba labels for DR soybeans include:

  • Must use an approved volatility-reduction agent.
  • Follow revised cutoff dates. There are slight differences in wording among registered products:
    • Xtendimax w/VGT:  Apply before June 30 or up to R1 stage, whichever comes first
    • Engenia:  Apply before June 30
    • Tavium w/VGT: Apply before June 30 or up to the V4 stage, whichever comes first
  • Always maintain a 240-ft buffer between last treated row and downwind field edge. This is an increased from the previous 110 ft buffer. Roads, mowed grass and tolerant crops can be included in the buffer. The previous Xtendimax label also included a 220 ft buffer at 44 oz. The 44 oz rate has been eliminated from the label.

Other restrictions still apply:

  • Apply only one hour after sunrise through two hours before sunset
  • Apply when wind speed at boom height is between 3 and 10 MPH
  • Do not apply during temperature inversions
  • Do not apply product if sensitive crops or certain plants are in an adjacent downwind field
  • Do not apply if rain is expected in next 48 hours that may result in runoff
  • Maximum boom height of 24 inches
  • Maximum ground speed of 15 MPH
  • Dicamba specific training is still required
  • A 310 ft downwind buffer and 57 ft omni-directional buffer required in counties with endangered species. This applies to the counties of Allamakee, Clayton, Delaware, Dubuque, Jackson, Iowa and Hardin. The labels direct users to an EPA website that provides up-to-date information on endangered species.


Effectiveness of Using Low Rates of Plant Nutrients

This is a new publication summarizing research results from the upper Midwest. Although some producers may think about using low rates of fertilizer to reduce input costs, this can adversely affect yields if soil fertility drops below optimal levels. Read about the research to help your decision-making. The publication is a free download available at:
