Training Requirements and Application Reminders for XtendiMax® herbicide with VaporGrip® Technology - SD

​​​​​​​​

The Roundup Ready® Xtend Crop System is designed to help control herbicide resistant and tough-to-control broadleaf weeds in soybean. Two of the components of the system are Roundup Ready 2 Xtend® soybean and a dicamba formulation product, XtendiMax® herbicide with VaporGrip® Technology.

Dicamba and glyphosate herbicides can be utilized to manage weeds as a burndown, pre-planting, and as an in-crop option on Roundup Ready 2 Xtend® soybeans. Also, XtendiMax herbicide with VaporGrip Technology offers potential soil activity for up to 14 days on certain small-seeded broadleaf weeds depending on rainfall and soil type. The wide application window allows for control of small weeds (less than 4 inches) when they are more vulnerable, such as marestail at early burndown. The ability to use this product through the planting window will allow for Roundup Ready 2 Xtend soybeans to get a head start towards their high yield potential with minimal competition from weeds.

A weed management program should also include traditional residual herbicides in pre-emergence and post-emergence applications that have different sites of action. Targeting weeds that have not yet emerged or are small (less than 4 inches) will contribute to a more successful weed management program.

Use of XtendiMax herbicide with VaporGrip Technology has various application requirements that can vary by state including nozzle selection, set-back distances from sensitive areas, spray volume, etc. A few key points when applying XtendiMax herbicide with VaporGrip Technology include:

  • Do not use ammonium sulfate (AMS) or ammonium-based additives with XtendiMax herbicide with VaporGrip Technology.
  • Apply when wind speed measured at the boom is between 3 and 10 mph and do not spray during an inversion.
  • Do not exceed 15 mph ground speed.
  • Use only approved tank-mix partners found at www.xtendimaxapplicationrequirements.com. Refer to all product labels to determine mix order or perform mix compatibility tests.
  • Mandatory recordkeeping documentation includes daily sprayer cleanout, start and stop times, wind speed, wind direction, and temperature at boom height, as well as the type of equipment used to make these measurements. Commercial and non-commercial applicators must complete records within 48 hours.

Always read and follow the most current pesticide label requirements.
