Consultation on Isoxaflutole and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2021-02
Health Canada is consulting Canadians on the proposal to continue registration of all uses of isoxaflutole and associated end-use products registered for sale and use in Canada.
The re-evaluation of isoxaflutole pesticides, including human health and environmental risk assessments, indicated that risks were shown to be acceptable when isoxaflutole is used according to proposed conditions of registration, which includes new mitigation measures.
To protect human health, risk mitigation measures include:
- Label improvements including a spray drift advisory statement
- A restricted-entry interval of 12 hours to protect workers
To protect the environment, the following risk mitigation measures are proposed:
- Standard label statements to inform users of the potential toxic effects of isoxaflutole to aquatic organisms and terrestrial plants
- Spray buffer zones to protect aquatic and terrestrial habitats
- A leaching advisory statement
- Precautionary label statements to reduce the potential for runoff of isoxaflutole to adjacent aquatic habitats for sites with characteristics that may be conducive to runoff and when heavy rain is forecast
For a full list of products containing isoxaflutole, 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".
