Identify commercial specialty or certified organic crops near the application site prior to herbicide application. Do not apply FeXapan™ when the wind is blowing toward adjacent non-dicamba tolerant susceptible crops; this includes NON-Dicamba Tolerant Soybean and Cotton.

Always maintain a downwind buffer between the last treated row and the nearest downwind field edge (in the direction the wind is blowing).

  • When applying 22 fl. oz./A of FeXapan™, maintain a 110-foot buffer
  • When applying 22+ to 44 fl. oz./A of FeXapan™, maintain a 220-foot buffer

No application of these products can be made in the buffer area.

The following areas may be included in the downwind buffer distance calculation:

  • Roads, paved or gravel surfaces
  • Planted agricultural fields containing corn, dicamba tolerant cotton or soybeans, sorghum, proso millet, small grains and sugarcane
  • Agricultural fields prepared for planting
  • Areas covered by the footprint of a building or man-made structure with walls and/or roof

Follow FeXapan™ stewardship guidelines to ensure effective weed control and to minimize risk of off-target herbicide movement.
