Processes and Procedures for Plant Protection Products – Changes to the Detailed Technical Sift Criteria.

On 29th June 2016 HSE introduced new processes and procedures for the authorisation of plant protection product applications under Regulation (EC) No 1107/2009.  Changes to the criteria for the Detailed Technical Sift are now being introduced, following receipt of feedback.  The key changes being introduced, on 27th November 2017, are:

General issues (e.g. discrepancies in the GAP, label, addressing EFSA data gaps) relevant to all specialist areas have been included in a new separate section Minor issues, those not considered reasons for rejecting an application but may need to be addressed for an authorisation, will be highlighted to applicants in the conclusion of the DTS. Highlighting these issues early in the evaluation process will provide additional time for them to be addressed by applicants Based on experience a number of rejection criteria have been removed from each specialist area Links to UK and EU guidance documents have been included to support applicants preparing an application for submission The mammalian toxicology section has been separated out into mammalian toxicology and operator exposure

The changes to the DTS criteria are outlined in the guidance document ‘Overview of the Processes and Procedures for the Authorisation of Plant Protection Productions in the UK under Regulation (EC) No 1107/2009.
