The European Union (EU) Observatory for Nanomaterials (EUON) announced on November 12, 2024, that it published a new study evaluating nanomaterials applications in biocidal, plant protection, and fertilizing products used in agriculture. The study, “Collection and review of information on nanomaterial-based and nano-enabled plant protection products, biocidal products and fertilising products,” addresses knowledge gaps on applications, exposure, and hazards of nanomaterials and nano-agrochemicals, as well as the advantages of using them. According to the abstract, a literature search “found 3,052 relevant documents from databases with scientific literature and grey literature, assessing nano-agrochemicals’ market presence and their comparative efficacy and safety.” The authors’ analysis found that “nano-agrochemicals often offer enhanced performance, suggesting a shift towards sustainable agriculture.” The study notes that existing regulations such as the Plant Protection Products Regulation (EC) No 1107/2009 and Fertilising Products Regulation (EU) 2019/1009 “lack specific provisions for nanoforms, unlike the Biocidal Products Regulation (EU) 528/2012.” Recommendations include updating legislation to define and consider nano-agrochemicals, establishing a framework for standardized use instructions, creating an EU-level nano-agrochemicals database, and implementing a notification system for manufacturers.
