The European Union has officially banned the herbicide flufenacet, with product authorizations to be withdrawn by December 10, 2025

The reasons for the ban are detailed as follows: 1. Clear Endocrine Disrupting Characteristics (EDC): The European Food Safety Authority (EFSA) assessment confirmed that flufenacet meets the criteria for an endocrine disruptor targeting the thyroid hormone pathway (T-mode). This means the substance has potential to interfere with the endocrine systems of humans and non-target organisms (such as wildlife), potentially triggering adverse health effects and posing long-term threats to the ecological environment. 2. Unacceptable Groundwater Pollution Risk: The assessment found that flufenacet's key metabolite trifluoroacetic acid (TFA) is confirmed to have reproductive toxicity. In all groundwater exposure scenarios reviewed by the EU, TFA's predicted environmental concentration (PEC) significantly exceeded the legal limit of 0.1 μg/L set by the EU Groundwater Directive (2006/118/EC). This indicates that in actual agricultural applications, TFA is highly likely to continuously seep ...
