据欧盟食品安全局（EFSA）消息，2024年8月12日，欧盟食品安全局就活性物质绿草定（triclopyr）的农药风险评估发布同行评审。
经过评估，将绿草定作为除草剂用在已建牧场和非娱乐休闲草地(田间使用）的基础上，欧盟食品安全局提出了适用于监管风险评估和建议的最大残留限量的可靠端点，列出了监管框架要求的缺失信息，发现问题时会进行报告。部分原文报道如下：
The conclusions of the European Food Safety Authority (EFSA) following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State Poland and co-rapporteur Member State Hungary for the pesticide active substance triclopyr (variant triclopyr-butotyl) and the assessment of applications for maximum residue levels (MRLs) are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012, as amended by Commission Implementing Regulation (EU) No 2018/1659. The conclusions were reached on the basis of the evaluation of the representative uses of triclopyr (variant triclopyr-butotyl) as a herbicide on established pasture and non-recreational amenity grassland (field use). MRLs were assessed in rice. The reliable end points, appropriate for use in regulatory risk assessment and the proposed MRLs, are presented. Missing information identified as being required by the regulatory framework is listed. Concerns are reported where identified.
