Canada – Clethodim, Proposed Maximum Residue Limit (PMRL2024-21)

Current status: Open
Opened on 2 October 2024 and will close for consultation on 16 December 2024

Health Canada is consulting the public and seeking your feedback on a proposed maximum residue limit (MRL) increase for the use of clethodim on lowbush blueberries.

An MRL is the highest amount of a specific pesticide residue allowed on a particular food when a pesticide is used according to label directions.

The proposed MRL increase for clethodim on lowbush blueberries is being requested to support the Canadian use of clethodim on lowbush blueberries with cranberry data that better represent the proposed use than the highbush blueberry data used to calculate the previously established MRL.

This proposed MRL change allows lowbush blueberries treated with clethodim, or any processed food derived from it, to be grown and sold in Canada. This MRL change also applies to this food being imported into Canada.

Clethodim

Clethodim is a herbicide currently registered for use in Canada on various fruit, vegetable, grain, herb and spice commodities.
Clethodim was first registered in Canada in 1992.

What is the proposed MRL decision 
This consultation is on the proposed decision to: 

Increase the MRL for clethodim from 0.2 parts per million (ppm) to 0.5 ppm on lowbush blueberries.

Health Canada conducted scientific evaluations to determine the potential impact on human health of the new clethodim use. The scientific evaluations show that the proposed revised MRL for clethodim would continue to meet Health Canada’s requirements for the protection of human health.
