Biological pesticides

The programme (or BioPesticides including microbials - bacteria, algae, protozoa viruses, fungi -, pheromones and semiochemicals, macrobials/invertebrates such as insects and nematodes, and plant extracts/botanicals) helps member countries to harmonise the methods and approaches used to assess biological pesticides.

Best Available Techniques (BAT) to Prevent and Control Industrial Pollution

On 5 May 2022, the OECD hosted a webinar to discuss how to incorporate value chain approaches in BAT determinations and related environmental regulatory concepts as well as the challenges faced and possible solutions. Watch the webinar replay and access the presentations.

Safety Assessment of Transgenic Organisms: OECD Consensus Documents

The OECD biosafety consensus documents identify elements of scientific information used in the environmental safety and risk assessment of transgenic organisms which are common to OECD member countries.

Safety Assessment of Transgenic Organisms in the Environment, Volume 9 - OECD Consensus Documents on the Biology of Crops: Apple, Safflower, Rice

eChemPortal: Global Portal to Information on Chemical Substances

This collection of case studies includes a variety of studies where chemicals are grouped together for a risk assessment. This addition improves accessibility to risk assessment data for governments, scientists and industry.

Webinar Series on Testing and Assessment Methodologies

On 6 April 2022, the OECD organised a second webinar on the application of the assessment framework for Physiologically Based Kinetic (PBK) models. The webinar presented two case studies and illustrated how the templates of the guidance were used to report and evaluate PBK models. A discussion took place on challenges related to the regulatory evaluation of PBK models and clarifications on aims and scope of these models were provided.

OECD Seminar on Different Aspects of Efficacy Evaluation of Biopesticides

28-29 June 2021: The Seminar covered the efficacy evaluation of the different categories of biopesticides, new application techniques, efficacy evaluation of biopesticides based on plant defence inducers (PDI), comparison of efficacy requirements for biostimulants vs. biopesticides, how to evaluate different Integrated Pest Management (IPM) modules, and registration pathways with limited or no evaluation of efficacy.

Webinar Series on Emerging Science to Improve Chemical Safety

On 16 March, the OECD and the EU Joint Research Centre organised a webinar to discuss the report on Addressing evidence needs in chemicals policy and regulation. It presented the main findings of the report and a set of actionable recommendations, including how knowledge management systems can be designed in a user-centric fashion to address current challenges, with the Adverse Outcome Pathway framework being a prominent example.
