Changes to the iprodione pesticides registration

All pesticides used in Canada must be registered under the Pest Control Products Act. Pesticides are re-evaluated to ensure that they continue to meet health and environmental requirements. Re-evaluation may result in the revocation of a product or product uses. Health Canada may also request changes to a product's label, including mitigation measures, use sites and application methods.

Iprodione is a fungicide used on greenhouse, orchard and field crops, ornamentals and turf. Highlights of the re-evaluation decision for the active ingredient iprodione, published on June 21, 2018, are summarized below.
