Re-evaluation Decision

Under the authority of the Pest Control Products Act, all registered pesticides must be regularly re-evaluated by Health Canada’s Pest Management Regulatory Agency (PMRA) to ensure that they continue to meet current health and environmental safety standards and continue to have value. The re-evaluation considers data and information from pesticide manufacturers, published scientific reports and other regulatory agencies. The PMRA applies internationally accepted risk assessment methods as well as current risk management approaches and policies.

Iprodione is a contact fungicide with protective and curative action. It is used to control a broad range of fungal pathogens on a wide variety of greenhouse, orchard and field crops, ornamentals and turf. Currently registered products containing iprodione are listed in Appendix I. Registered product labels containing iprodione in Canada can be accessed through the PMRA’s label transcription service.Footnote 1

This document (Re-evaluation Decision RVD2018-16, Iprodione and Its Associated End-use Products) presents the final regulatory decisionFootnote 2  for the re-evaluation of iprodione, including the required risk mitigation measures to protect human health and the environment. All products containing iprodione that are registered in Canada are subject to this re-evaluation decision.

This re-evaluation has undergone a 120-day consultation period on the Proposed Re-evaluation Decision PRVD2016-09, Iprodione, Footnote 3 which ended on 15 July 2016. The PMRA received comments relating to health, environment and value. These comments are summarized in Appendix II of RVD2018-16 along with responses by the PMRA. These comments and new data/information resulted in revisions to the risk assessments (see Science Evaluation Update of RVD2018-16), and subsequently, in changes to the proposed regulatory decision as described in PRVD2016-09. A reference list of data used as the basis for the proposed re-evaluation decision is included in PRVD2016-09, and further data used in the re-evaluation decision is listed in Appendix VII of RVD2018-16.

Regulatory Decision for Iprodione

The PMRA has completed the re-evaluation of iprodione. Under the authority of the Pest Control Products Act, the PMRA has found the continued registration of some products containing iprodione to be acceptable for sale and use in Canada. An evaluation of available scientific information found that some uses of iprodione products meet current standards for the protection of human health or the environment, when used according to the conditions of registration which include required amendments to label directions. Certain uses of iprodione are cancelled to address potential risks of concern for human health. Label amendments, as summarized below and listed in Appendix VI of RVD2018-16, are required for all end-use products. No additional data are requested.

Risk Mitigation Measures

Registered pesticide product labels include specific instructions for use. Directions include risk mitigation measures to protect human health and the environment. Following these directions is required by law. As a result of the re-evaluation of iprodione, the PMRA is requiring further risk mitigation measures in addition to those already identified on iprodione product labels.

Human Health

  • Removal of the following uses from the labels of commercial class products:
    • Garlic seed dip.
  • Cancellation of the following uses from the labels of commercial class products:
    • Foliar treatment of canola, alfalfa, strawberries, raspberries, peaches, plums, prunes, cherries, apricots, grapes, lettuce, cauliflower, cabbage, snap beans, kidney beans, white beans, onions, leeks, and ginseng;
    • Turf;
    • Foliar treatment of greenhouse and outdoor cut flowers;
    • Greenhouse tomato and cucumber;
    • Seed treatment of canola and mustard;
    • Potato seed treatment for seed potatoes.
  • The following uses are acceptable for continued registration when required mitigation measures, as outlined below, are implemented:
    • Foliar application to outdoor and greenhouse potted ornamentals (non-cut flowers);
    • Soil drench application to outdoor and greenhouse ornamentals (including cut flowers);
    • Greenhouse lettuce;
    • Conifer seedlings;
    • Potato seed treatment for table and processing potatoes;
    • Imported treated carrot seed.
  • Required mitigation measures:
    • Mixers/loaders and applicators: increased personal protective equipment (PPE) and prohibition of certain handheld application equipment (mist blower and fogger).
    • Postapplication workers: increased restricted-entry intervals (REIs) for some activities and limited number of applications for most crops.
    • For potato seed treatment (table and processing potatoes):
      • Increased PPE and limit to amount treated per day.
      • A plant back interval (PBI) of 30 days is required for all crops except root vegetables (crop group 1) and leafy brassica greens (crop group 5b). The PBI requirement for crop group 1 and 5b is 12 months.
    • To protect bystanders from spray drift: a statement to promote best management practices to minimize human exposure from spray drift or spray residues resulting from drift.

Environment

  • Spray buffer zones to protect non-target habitats from pesticide spray drift (1 to 2 m for freshwater habitats).
  • Standard runoff reduction labelling.
  • Hazard statements on product labels warning of the potential to contaminate groundwater through leaching.
  • Warnings on foliar use product labels regarding toxicity of iprodione to aquatic organisms, birds, and bees.
  • Hazard statement on all seed treatment product labels stating that any spilled or exposed seeds must be incorporated into the soil or otherwise cleaned-up from the soil surface.
  • Warning on greenhouse product labels that use may harm bees and other beneficial insects used in greenhouse production.

International Context

Iprodione is currently acceptable for use in other Organization for Economic Co-operation and Development (OECD) member countries, including the United States, and Australia. In November 2017, the European Commission published a decision of non-renewal of iprodione as a plant protection product. Therefore, the PMRA has initiated a special review under subsection 17(2) of the Pest Control Products Act. No other decision by an OECD member country to prohibit all uses of iprodione for health or environmental reasons has been identified.

Next Steps

To comply with this decision, the required mitigation measures must be implemented on all products labels sold by registrants no later than 24 months after the publication date of this decision document. Appendix I lists the products containing iprodione that are registered under the authority of the Pest Control Products Act.

Other Information

Any person may file a notice of objectionFootnote 4  regarding this decision on iprodione within 60 days from the date of publication of this Re-evaluation Decision.
