Consultation on Difenoconazole and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2021-06
Health Canada is consulting Canadians on the proposal to continue registration of difenoconazole and all associated end-use products registered for sale and use in Canada.
With respect to human health, occupational and postapplication risks were shown to be acceptable when difenoconazole is used according to proposed conditions of registration, which include new mitigation measures, such as updated engineering controls, personal protective equipment, statements reducing potential drift and hazard statements on seed tags. Dietary risks were shown to be acceptable when used according to current conditions of registration.
Based on available scientific information, potential risks to the environment were shown to be acceptable when difenoconazole is used according to the proposed conditions of registration, which includes new mitigation measures such as additional precautionary label statements and spray buffer zones.
Difenoconazole controls a wide range of fungal diseases on different field crops, fruits, vegetables and turf as a foliar spray, post-harvest spray and as a seed treatment. It is of particular importance for the control of Fusarium dry rot in potato as there are few registered alternative active ingredients to manage this storage pathogen.
For a full list of products containing difenoconazole, 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".
