EU pesticide reforms spark backlash from scientists over weakened safeguards

Researchers from 27 European institutions have raised concerns over the proposed Omnibus Package. They warn it could weaken key safeguards in the EU’s pesticide approval system. Their analysis highlights several risks tied to the planned changes. Under current rules, active substances in pesticides undergo regular re-evaluations. Since 2011, this process has led to 59 substances being denied reapproval due to health or environmental risks. The Omnibus Package, however, would grant most active substances indefinite approval, removing the need for periodic reviews.

The proposal also shifts the burden of proof from manufacturers to authorities. It would extend the phase-out period for banned substances to up to three years. Additionally, it reduces the role of scientific evidence in national product authorisations.

The researchers argue that these changes could discourage innovation in pesticide development. They point out the lack of systematic monitoring to detect risks after approval. The package also omits an automatic review mechanism for approved substances. The researchers urge the EU to maintain strict safeguards. They call for public access to approval studies and stronger post-authorisation monitoring. They also recommend assigning evaluations based on expertise and keeping the burden of proof on manufacturers.
