欧盟《综合法案X》在5月获得欧洲理事会批准，该法案提议允许无人机精准喷洒农药，以替代传统飞机施药方式1。欧盟的目标是通过这一举措到2030年将化学植保用量减半1。然而，这项政策同时放宽了农药有效物质的审批规则，引发科学家的严重关切。
根据现行规定，农药有效物质的批准期限为10年，自2011年以来已有59种物质未获得重新批准1。新政策将批准期满后的过渡期从18个月延长至3年1，批评者警告这可能导致有害物质获得无期限批准，淘汰定期重新评估机制1。草甘膦等有害物质因此可能长期存在市场1。
农业经济学家托马斯·道姆指出，"无人机本身不能节省任何农药"1。他进一步指出，杀菌剂必须预防性使用，无人机精准喷洒方案对其无效1。
The European Union's proposed Comprehensive Regulation X, approved by the European Council in May 2026, aims to reduce chemical plant protection product use by half by 2030 through the deployment of precision drone technology for pesticide application 1. However, the initiative has drawn significant scrutiny from scientists and agricultural economists who contend that the policy may ultimately undermine rather than advance the bloc's sustainability goals.
Agricultural economist Thomas Daum has pointed out that "drones themselves cannot save any pesticides," challenging a core assumption underlying the proposal 1. The concern intensifies when considering fungicides, which must be applied preventatively—a requirement for which precision drone spraying offers no advantage 1. Critics argue that while drones may enable more targeted application, this alone will not reduce overall pesticide consumption. More troublingly, the regulation threatens to weaken the approval framework for active pesticide substances. Historically, such substances have been granted approval for ten-year periods, with 59 substances failing to secure renewal since 2011 1. The new framework would extend the transition period following approval expiration from 18 months to three years 1, and experts warn this could lead to indefinite market authorization for certain active ingredients, effectively eliminating the requirement for periodic reassessment 1. Substances such as glyphosate could potentially remain on the market long-term as a result 1, contradicting the precautionary principle that underpins EU environmental policy.
Experts have suggested that integrated pest management approaches offer a more effective alternative to both the current pesticide regime and the drone-based spraying model proposed in the regulation 1.
