What did Health Canada determine
about 2,4-D with its most recent decision?
After 25 years of analyzing all the pertinent science and considering the public’s input in 2005 and again in 2008, Health Canada’s Pest Management Regulatory Agency (PMRA) has determined that 2,4-D may be used safely according to label directions. With specific regard to use on lawns, the PMRA stated:

Health Canada has determined that 2,4-D meets Canada’s
strict health and safety standards.

Risks to homeowners and their children from contact with treated lawns and turf are not of concern.”
