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:
Always read and follow the most current pesticide label requirements. Additional up-to-date information about the Roundup Ready Xtend Crop System and the use of XtendiMax with VaporGrip Technology, including approved tank-mix partners and the use of drift reduction adjuvants (DRAs), are available at the following website: XtendiMaxApplicationRequirements.com
Mandatory Training: Under the revised Environmental Protection Agency (EPA) registration for XtendiMax herbicide with VaporGrip Technology, the product is now a restricted use pesticide and requires users to be a certified applicator (private or commercial) AND receive mandatory dicamba or auxin-specific training.
