GB maximum residue level (MRL) amendments: adopted July 2026

The GB MRL Statutory Register has recently been amended and new statutory levels have been set.

To meet the requirements of international trade, and to accommodate a new authorisation of a plant protection product in GB, new MRLs have been set in the GB MRL Statutory Register for the following active/commodity combinations. The date the new MRLs came into force is also detailed:

10 July 2026

  • Potassium phosphonates/asparagus

31 July 2026

  • Flonicamid/ potatoes, lettuces, escaroles/broad leaved endives

The evaluation reports, reasoned opinions and decision documents supporting the new MRLs are available on the HSE website.

Stakeholders should note that pesticides is in scope of the Sanitary and Phytosanitary (SPS) agreement currently being negotiated between the UK and the EU. Once negotiations on the SPS Agreement have concluded, HSE will communicate further on any implications the agreement has for the sector.
