OFA has provided input to the Pest Management Regulatory Agency (PMRA) as part of the consultation process for proposed special review decisions of dicamba and its associated end-use products.

OFA urges PMRA to reconsider its proposed cancellation of dicamba uses, arguing that dicamba-tolerant corn and soybean systems are a critical innovation for managing difficult to control and herbicide-resistant broadleaf weeds. OFA maintains that cancelling all post-emergent dicamba use in soybeans and eliminating its use in dicamba-tolerant soybean seed production is overly restrictive, not fully supported by current science, and risks significant economic and supply-chain consequences for Canadian farmers, particularly amid trade instability with the United States.

OFA recommends targeted risk-mitigation measures such as narrower application timing, enhanced buffer zones, and clear temperature-based stewardship requirements to address off-target movement while preserving farmer access to the tool. OFA further stresses that any regulatory changes must allow at least one full growing season for implementation to avoid serious disruption to farm operations and the food supply, and calls for more transparent, earlier, and ongoing stakeholder engagement in PMRA’s regulatory processes.
