Monitor Wind Speed When Applying Herbicides

Follow guidelines for wind speed during herbicide applications.

Environmental conditions play a significant role in determining effective spray coverage and weed control. Ignoring wind speed can result in off-target movement and crop injury. Low or no wind movement can indicate a temperature inversion, which can increase movement of small spray particles and herbicide vapors. High wind speed can increase drift potential and off-target herbicide movement.

Use these guidelines when applying DuPont™ FeXapan™ herbicide Plus VaporGrip® Technology:

Wind Speed

Apply FeXapan™ when wind speed is between 3 and 10 miles per hour as measured at the height of the boom for application.

  • Apply FeXapan™ when wind speed is between 3 and 10 miles per hour as measured at the height of the boom for application.
  • Do not apply FeXapan™ when wind speed is less than 3 miles per hour.
  • Do not apply FeXapan™ when the wind is blowing toward adjacent non-dicamba tolerant susceptible crops; this includes NON-Dicamba Tolerant Soybean and Cotton.

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