Canada’s PMRA continues to conclude 2,4-D is acceptable for continued registration. The PMRA has concluded that 2,4-D does not pose a health risk under the current conditions of use in Canada. This decision comes after a review of extensive scientific data, including the latest assessments of the European Food Safety Authority (EFSA), International Agency for Research on Cancer (IARC), and the United States Environmental Protection Agency (USEPA). The PMRA has also concluded that there are no reasonable grounds to believe that 2,4‑D may cause an unacceptable environmental risk and value continues to be realized by Canadian farmers, ranchers, rights-of-way managers and homeowners.


2,4-D Research Task Force has prepared and submitted comments in response to the EPA’s Registration Review Draft Risk Assessments. The Task Force notes the EPA’s overall finding of no human health concerns and supports continued product stewardship to reduce any calculated levels of concern for non-target organisms, in order to preserve 2,4-D’s many beneficial uses. The EPA’s draft human health risk assessments states that the following risks are not of concern: dietary, residential, non-occupational, volatilization/residential bystander and aggregate risk estimates. Recent EPA review documents have noted that; “2,4-D is not likely to carcinogenic in humans.”


Review of EPA’s Draft Human Health Risk Assessment for 2,4-D align with previous findings. This review reinforces previous assessments by the EPA: 2,4‑D can continue to be used according to label instructions to protect food production and the environment. Ready to have your voice heard?

The 2,4-D Task Force is pleased to partner with the American Soybean Association and the Arkansas State Plant Board in the production of a new video to encourage producers to have on target applications.
Good neighbor relationships are vital to farmers, ranchers, and producers. To continue our strong heritage of stewardship, the 2,4-D Task Force encourages farmers to communicate with their neighbors, read and follow all label instructions and follow any additional state restrictions to avoid pesticide misuse.
