During the 2024 Dublin Plant Protection Symposium, held on November 20th and 21st, Jeroen Meeussen, Regulatory Adviser from the International Biocontrol Manufacturers Association (IBMA), presented the latest developments in biological control (biocontrol) in the EU.
To start his presentation, Jeroen defined the biocontrol sector and highlighted IBMA’s role in its development. Biocontrol, although still lacking a formal EU definition, is an industry focused on using macrobials, microbials, natural substances, and semiochemicals as sustainable alternatives in agriculture. The IBMA acts as the voice of biocontrol technologies, promoting innovation in sustainable agriculture. Additionally, the IBMA advocates for proportionate regulations to facilitate the market introduction of biocontrol solutions.
Jeroen then covered updates in each biocontrol subsector, starting with microorganisms. He introduced a new database containing references to methods and guidance documents addressing data requirements for microbial active substances and PPP datasets. Jeroen also discussed new regulations on Digital Labelling (proposed amendments to Regulation 547/2011) which will be effective in January 2026. Many are concerned, especially regarding microbials that they will be unfairly categorised if placed in Category C despite being low-risk.
The next subject addressed were semiochemicals, substances emitted by plants, animals, and other organisms for inter- and intra-species communication. A new guidance document, SANTE/12815/2014 Rev. 11, introduces definitions for semiochemicals, including Straight Chain Arthropod Pheromones, Other Chained Arthropod Pheromones (OCAPs), and Other Arthropod Pheromones (OAPs).
For natural substances, Jeroen emphasised that the existing guidance on botanicals works well for single entities and simple mixtures, but more detailed guidance is needed for complex mixtures, focusing on the identity of natural substances, lead component risk assessment, and study designs.
For invertebrates, Jeroen recommended the EPPO list for safe IBCAs like insects and nematodes, stressing standards to show no adverse effects and the need for a Commercial Use Indicator backed by evidence.
Jeroen concluded his presentation by discussing the future of biocontrol. With global agricultural priorities increasingly focusing on sustainability, biocontrol enjoys broad political support. Establishing a harmonised EU definition and fit-for-purpose risk assessment can ensure timely market access for biocontrol products without compromising safety. Finally, the IBMA proposed for a new biocontrol agency to be established similar to the European Medicines Agency.
