Consultation on Zoxamide and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2022-06

Notice to the reader:

The online consultation is now closed.

Health Canada is consulting Canadians on the proposal to continue registration of zoxamide and all associated end-use products registered for sale and use in Canada, provided new risk measures are put in place.

Zoxamide is a fungicide registered for the control of fungal diseases on potatoes, grapes and onions. Zoxamide is a valuable disease management tool for vegetable and grape growers due its rainfastness, residual properties and low to medium risk for resistance development.

With respect to human health, risks from all uses were shown to be acceptable under the current conditions of use. Zoxamide risk to non-target terrestrial organisms (earthworms, beneficial arthropods, honeybees, birds, wild small mammals and terrestrial plants) are considered to be acceptable for all registered uses with no additional mitigation measures. Risks from spray drift and runoff of zoxamide, at the currently registered rates, were identified for certain aquatic organisms. Risk mitigation measures proposed to protect aquatic organisms include additional precautionary label statements and spray buffer zones.

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

For more information on the proposed decision open the “Proposed Re-evaluation Decision”.
