Consultation on Kaolin and the Associated End-use Product, Proposed Re-evaluation Decision PRVD2021-12

Notice to the reader:

The online consultation is now closed.

Health Canada is consulting Canadians on the proposal to continue registration of products containing kaolin for sale and use in Canada, provided that the proposed updates to label directions are in place.

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 certain 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 products have value as a pest management solution. When the current label directions are followed, potential risks to human and the environment are considered to be acceptable. As a result of the re-evaluation of kaolin, no further risk mitigation measures are being proposed. However, label updates are proposed to meet the current labelling standards.

For a full list of products containing kaolin, 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".
