2,4-D Acceptable for Continued Use in Canada


OTTAWA, March 31, 2016 – Health Canada’s Pest Management Regulatory Agency (PMRA) has concluded that “Evaluation of available scientific information related to the aspects of concern for human health and the environment, indicated that the registered products containing 2,4-D are acceptable for continued registration taking into account the current conditions of use.”

“The PMRA’s assessment of scientific data base is another, consistent regulatory decision that concludes the use of 2,4-D not only protects food production but also the environment,” stated Jim Gray, Executive Director of the Industry Task Force II on 2,4-D Research Data.

“The PMRA’s findings bolster expert reviews and earlier decisions of authorities such as the World Health Organization, U.S. Environmental Protection Agency, European Commission, and European Food Safety Authority. After examining human health and environmental risk conditions, the PMRA determined that the use of 2,4-D for all registered uses in Canada meets modern standards. The conclusion is consistent with the PMRA’s previous reviews, including the Re-evaluation decisions in 2005, 2007, 2008, and 2013.

An economic analysis prepared by RIAS Inc. in 2006 examined the benefit of 2,4-D and other phenoxy herbicides. The report concluded that Canadian food producers would face $227 million in additional costs (133% increase) if phenoxy herbicides were not available. Most notably, 2,4-D has long been recognized as being a superior tank mixing partner with other herbicides, and that after seven decades of use, 2,4-D continues to show little evidence of weeds developing resistance to this product.

With this most recent regulatory decision, Canadian farmers, ranchers, grain producers, forestry and green space managers will be able to continue deriving benefit from the many low cost, effective uses of 2,4-D.

About the Task Force

The Industry Task Force II on 2,4-D Research Data is organized to provide funding for the on-going Good Laboratory Practice (GLP) research studies required to respond to the US EPA registration review and PMRA pesticide re-evaluation programs. The 2,4-D Task Force is comprised of those companies holding technical 2,4-D registrations: Dow AgroSciences (U.S.), Nufarm, Ltd. (Australia) and Agro-Gor Corp., a U.S. corporation jointly owned by Albaugh, LLC. (U.S.) and PBI-Gordon Corp. (U.S.).
