Monsanto announced today that the EPA has approved XtendiMax herbicide with VaporGrip Technology, a low-volatility dicamba herbicide for in-crop use with Roundup Ready 2 Xtend soybeans and Bollgard II XtendFlex cotton. This gives farmers the option to use dicamba in the Roundup Ready Xtend Crop System in 2017.
Availability will require state approvals.
“Based on the great demand we’ve seen in 2016, we know our farmers are looking forward to the benefits of the Roundup Ready Xtend Crop System, including in-crop use of dicamba and glyphosate,” said Brett Begemann, Monsanto president and chief operating officer. “Growers have been asking for this…technology for years, and we’re excited to be able to provide it in 2017.”

EPA’s registration is for a formulation of dicamba that contains an additive that reduces volatility. This formulation is different from the products that are alleged to have been recently used illegally. EPA continues to investigate these issues in several locations in the Midwest.
The label requires very specific and rigorous drift mitigation measures. Restrictions on the use of the product to further reduce the potential for exposure from spray drift include: no application from aircraft; no application when wind speed is over 15 mph; application only with approved nozzles at specified pressures; and buffer zones to protect sensitive areas when the wind is blowing toward them.
Weeds that are becoming increasingly resistant to glyphosate-based herbicides cause problems for farmers. This registration will provide an additional tool to reduce the spread of glyphosate resistant weeds. This final decision is designed to ensure that weed resistance is successfully managed, including reporting by the registrant to EPA of any suspected resistance, as well as remediation and grower education.
EPA is placing time limits on the registration to allow the Agency to either let it expire or to easily make the necessary changes in the registration if there are problems with resistant weeds or pesticide drift. Nevertheless, herbicide resistance is adequately addressed by the terms of the registration, and the Agency does not expect off-site incidents to occur.
This dicamba formula for use on dicamba-tolerant soybean and cotton has been registered for sale and use in Alabama, Arizona, Arkansas, Colorado, Delaware, Florida, Georgia, Illinois, Iowa, Indiana, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Virginia, West Virginia, and Wisconsin.
EPA proposed this decision on March 31, 2016. EPA’s final regulatory decision and supporting documents, including a response to public comments, are available in docket number EPA-HQ-OPP-2016-0187 at www.regulations.gov.
