Consultation on Chlorpyrifos and Its Associated End-use Products: Updated Environmental Risk Assessment, Proposed Re-evaluation Decision PRVD2019-05
Health Canada is proposing the cancellation of many uses of chlorpyrifos due to risks to the environment, with a small number of uses acceptable for continued registration in Canada.
Chlorpyrifos is a broad spectrum insecticide that is widely used to manage insects in production of fruits, vegetables, cereals, grains, legumes, tree nuts, oilseeds, greenhouse and outdoor ornamentals and turf. It is also applied in non-residential, outdoor areas to control mosquitos and destructive tree insects in and around non-residential buildings.
To protect the environment, almost all agricultural uses are proposed for cancellation. Uses acceptable for continued registration with label changes are:
- Standing water - temporary pools for larval mosquito control
- Outdoor adult mosquito control
- Structural indoor and outdoor (non-residential)
- Outdoor ornamentals (container stock only) for control of Japanese beetle larvae
- Greenhouse ornamentals
Updates to the labels of the remaining registered products include standard environmental statements to prevent effects on non-target species or aquatic systems.
For a full list of products containing chlorpyrifos, please consult Appendix I in the PRVD or visit the Pesticide Label Search database.
For more information on the proposed decision open the “Proposed Re-evaluation Decision”.
