Proposed re-evaluation decision

Under the Pest Control Products Act, all registered pesticides must be 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 different sources including from pesticide manufacturers, and other regulatory agencies. Health Canada applies internationally accepted risk assessment methods as well as current risk management approaches and policies.

Kaolin is a naturally occurring clay mineral and has a long history of use in a variety of consumer and food products. It is a mineral particle used in conjunction with several other integrated pest management practices as a broad-spectrum crop protectant to decrease damage from listed insect pests, sunburn and heat stress on crops. Kaolin is registered for use on pome and stone fruit, tree nuts, carrots, cucurbits, dry beans, grapes, leafy vegetables except Brassica vegetables, potatoes, raspberries and strawberries, and onions and shallots. Kaolin can be applied as a spray using air blast, high-pressure hand-held or boom sprayers.

This document (PRVD2021-12, Kaolin and the Associated End-use Product) presents the proposed regulatory decision for the re-evaluation of kaolin. Kaolin products have value in providing a pest management solution. When the current label directions are followed, potential risks to human health (occupational, dietary, residential and bystander) and the environment (aquatic and terrestrial organisms) are considered to be acceptable. However, label updates are proposed to meet the current labelling standards (Appendix II of PRVD2021-12). Updates to standard label statements related to human health (wording around protective dust masks and avoiding spray drift) and environment (wording to reduce runoff and protect aquatic habitats and drinking water) are proposed.

Under the authority of the Pest Control Products Act and based on the evaluation of currently available scientific information, products containing kaolin listed in Appendix I of PRVD2021-12 are being proposed for continued registration in Canada.

Registered pesticide product labels include specific directions for use. Directions include risk mitigation measures to protect human health and the environment that must be followed by law. As a result of the re-evaluation of kaolin, no further risk mitigation measures for product labels are being proposed. To meet current standards, label updates are proposed in Appendix II of PRVD2021-12.

All products containing kaolin registered in Canada are subject to this proposed re-evaluation decision. This document is subject to a public consultation,Footnote 1 during which written comments and additional information may be submitted to the PMRA. The final re-evaluation decision will be published taking into consideration the comments and information received during consultation.

Next steps

The public, including the registrants and stakeholders, are encouraged to submit comments and additional information during the 90-day public consultation period upon publication of this proposed re-evaluation decision.

All comments received during the 90-day public consultation period will be taken into consideration in preparation of re-evaluation decision document,Footnote 2 which could result in revised risk mitigation measures. The re-evaluation decision document will include the final re-evaluation decision, the reasons for it and a summary of comments received on the proposed re-evaluation decision PRVD2021-12 with Health Canada's responses.
