Agriculture Secretary Tom Vilsack announced on Wednesday several steps that the U.S. Department of Agriculture (USDA) is taking to address the increase of herbicide-resistant weeds in U.S. agricultural systems.

“Weed control in major crops is almost entirely accomplished with herbicides today,” said Vilsack. “USDA, working in collaboration with the Environmental Protection Agency, must continue to identify ways to encourage producers to adopt diverse tactics for weed management in addition to herbicide control. The actions we are taking today are part of this effort.”

USDA said the steps it is taking to help farmers manage their herbicide-resistant weed problems in “a more holistic and sustainable way” include:

  • USDA’s Natural Resource Conservation Service (NRCS) will offer financial assistance under its Environmental Quality Incentives Program (EQIP) for herbicide-resistant weed control practices that utilize Integrated Pest Management plans and practices.
  • Later this year NRCS will be soliciting proposals under the Conservation Innovation Grants (CIG) Program for innovative conservation systems that address herbicide resistant weeds.
  • USDA’s Animal and Plant Health Inspection Service (APHIS) will actively promote use of best management practices (BMPs) in design protocols for regulated authorized releases of genetically engineered crops and will include recommendations for BMPs with the authorization of field trials of HR crops.
  • USDA is partnering with the Weed Science Society of America (WSSA) and is providing funds to develop education and outreach materials for various stakeholders on managing herbicide–resistant weeds. The Secretary has directed Dr. Sheryl Kunickis, director of the USDA Office of Pest Management Policy, as the point person leading this effort with the USDA.

“With EPA’s announcement on the registration of new uses for herbicide mixtures containing the herbicides 2,4-D and glyphosate (in the Enlist formulation) in conjunction with new genetically engineered crop varieties, farmers are being offered one more new tool to better manage emerging populations of herbicide-resistant weeds in corn and soybeans crops,” USDA said. In its decision for 2,4-D use on genetically modified corn and soybean, EPA has outlined new requirements for registrants as part of a product stewardship program.

The USDA Office of Pest Management Policy worked with EPA to address the issue of herbicide resistance through appropriate label language that will require registrants to develop a stewardship program for the herbicide, develop training and education on proper use of the product that includes diversifying weed management, investigate and report nonperformance, and develop and implement a remediation plan for suspected herbicide-resistant weeds, USDA said.

“EPA intends to require the same stewardship plans for all new applications for product registration on GM crops with the goal being to encourage effective resistance management while maintaining needed flexibility for growers,” USDA said.

USDA said it will continue to work to ensure that growers have the diverse tools they need to address the management of herbicide resistant weeds.
