New Tank-Mixes Approved with Monsanto’s XtendiMax

Monsanto announced it has received approval for certain glyphosate tank-mixes with XtendiMax herbicide with VaporGrip Technology. The company recently listed the following products containing potassium salt formulations of glyphosate on www.xtendimaxapplicationrequirements.com as approved tank-mix products:

  • Roundup PowerMAX®Herbicide
  • Roundup PowerMAX® II Herbicide
  • Roundup WeatherMAX®Herbicide
  • Honcho® K6™ Herbicide
  • Abundit® Edge Herbicide

“Monsanto is committed to offering growers the lowest dicamba volatility potential solutions we can offer them. Monsanto believes that tank mixes of dicamba with potassium salt formulations of glyphosate have lower volatility potential than tank mixes with IPA and DMA salts of glyphosate based on humidome testing via published ASTM methodology,” the company said. For this reason, Monsanto plans to include only glyphosate products containing potassium salt of glyphosate as approved tank mix products with XtendiMax with VaporGrip Technology to the website at this time.

Approved glyphosate products will be limited to a maximum use rate of 32 fl oz per acre for each application when tank-mixed with XtendiMax with VaporGrip Technology for in-crop use with Roundup Ready 2 Xtend® soybeans and cotton with XtendFlex® technology.  This maximum use rate for glyphosate is consistent with expert recommendations for effective weed management within Roundup Ready PLUS® Crop Management Solutions.  In addition, the listed glyphosate options will require the use of SPECIFIC approved drift reducing adjuvants (DRAs) when tank-mixed with XtendiMax with VaporGrip Technology (see website for details).

In addition to the newly listed glyphosate products, we added two additional approved drift reducing adjuvants, AG16098 and CapsuleTM, providing additional DRA options along with the previously approved product Intact™. Specific DRAs are required for certain products specified on the tank mix website.  Monsanto supports enabling flexibility for growers to tank mix the most appropriate combinations for the best weed management recommendations specific to each grower’s field.

As a reminder, only after tank-mix products and/or nozzles are listed on the established tank-mix website are they considered approved and lawful to use or recommend as stated on product labels. All approved tank-mix products and nozzles for XtendiMax with VaporGrip Technology are listed on: www.xtendimaxapplicationrequirements.com.
