Proposed future GB MRL (maximum residue level) amendments

Ethoprophos, fenamidone, methiocarb, propiconazole and pymetrozine are no longer approved active substances in GB and all plant protection product authorisations have been withdrawn.

As harmful effects on human health cannot be excluded, it is proposed to lower all MRLs for these active substances to the limit of quantification.

You can view the draft Reasoned Opinions of the MRL review for ethoprophos, fenamidone, methiocarb, propiconazole and pymetrozine on our website.

The proposed date of adoption/publication of the new MRLs is 24 October 2022 and the proposed date of entry into force of the new MRLs will be six months after the date of adoption/publication.

To meet the UK’s international trade obligations, the measures have been notified to the World Trade Organization.

On completion of this process, an update on the final MRLs agreed, along with the date of entry into force, will be communicated via HSE’s ebulletin service.
