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

​​​​​​

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.

Always read and follow the most current pesticide label requirements as application requirements may differ between Wisconsin and Minnesota.
