EU Withdraws Approval for Herbicide Tritosulfuron Amid Unresolved Safety Concerns

Background on Tritosulfuron

Tritosulfuron, first included as an approved active substance in 2008, has been used extensively in plant protection products across the EU. Initially added under Directive 91/414/EEC, it transitioned to Regulation (EC) No 1107/2009, which oversees the market placement of such substances.

Decision and Rationale

The non-renewal follows the European Food Safety Authority's (EFSA) 2023 risk assessment. While no explicit risks were identified, the assessment left critical areas unresolved. The applicant's withdrawal of their renewal request in May 2024 solidified the Commission's stance to cease approval.

Implementation Timeline

The Commission's Implementing Regulation (EU) 2024/2777 mandates that EU Member States revoke tritosulfuron-based product authorisations by May 2025. Grace periods, where granted, are restricted to 12 months post-withdrawal, concluding in November 2025.

Supporting Information

This regulatory action underscores the EU's commitment to stringent safety and environmental standards under Regulation (EC) No 1107/2009. While tritosulfuron products will be phased out, stakeholders retain the option to reapply under Article 7 of the same regulation.

This step by the European Commission reflects its precautionary approach to public health and environmental safety, even in the absence of immediate, identified risks.
