Consultation on methyl bromide and its associated end-use products, Proposed Re-evaluation Decision PRVD2024-03

Current status: Open

Opened on 28 March 2024 and will close for consultation on 26 June 2024

Health Canada is consulting Canadians on the continued registration of the following uses of methyl bromide: general space fumigant, enclosed space fumigant and gas tight (tarpaulin) fumigant to treat empty structures or stored food/feed and non-food/non-feed commodities listed on the label.

The use of methyl bromide as a pre-plant soil fumigant is proposed for cancellation since the value was not shown to be acceptable because these uses do not meet the criteria for an exemption under the Montreal Protocol and is no longer used as a pre-plant soil fumigant for the crops registered on the label.

Methyl bromide is a broad-spectrum fumigant, effective as an insecticide, acaricide, fungicide, animal toxicant, molluscicide, nematicide, and herbicide. It is registered as a general space fumigation of structures (for example, warehouses, grain elevators, food processing plants, restaurants), enclosed space fumigation (i.e., chamber/vault; vacuum chamber; containers; and transport vehicles and gas tight covering (tarpaulin) fumigation). For these uses, it may be applied to empty structures or used to treat stored food/feed and non-food/non-feed commodities as listed on the label. It is also registered as a pre-plant soil fumigant for ornamental plants, forest nurseries and tomatoes.

With the proposed risk mitigation measures and label amendments, potential risks to human health and the environment are considered to be acceptable for methyl bromide and its end-use products when used as a general space fumigant, enclosed space fumigant, and gas tight (tarpaulin) fumigant to treat empty structures or stored food/feed and non-food/feed commodities, as specified on the label. Proposed mitigation and label amendments are summarized below and in Appendices III and IV of the proposed re-evaluation decision.

For a full list of products containing methyl bromide, please consult Appendix I in the Proposed Re-evaluation Decision or visit the Pesticide Label Search database.
