OECD Conference on RNAi based Pesticides

 

OECD Conference on RNA interference (RNAi) based pesticides

10-12 April 2019 OECD, Paris


The OECD Conference on RNAi based pesticides provided an overview on the current status and future possibilities for the regulation of externally applied dsRNA-based products that are proposed for use as pesticides. The event facilitated exchanges between policy makers, academia, industry on their implications in health, environment, and regulation. 

The focus on regulatory needs and aspects of risk assessment also aimed at informing the use of public and government funds in support of research on the use of externally applied dsRNA in agricultural agencies and institutes. 

Finally, hearing from regulatory authorities that have reviewed dsRNA-based crop traits helped informing regulatory policies at the national and international level and facilitate the development of a harmonised approach for regulating externally applied dsRNA-based plant protection products.

The Conference not only provided an overview but also inputs and recommendations for guidance(s) to be developed by the Working Group on Pesticides (WGP) and especially by its Expert Group working on RNAi-based pesticides. The guidance document(s) developed was made publicly available as practical tool(s) for policy makers and regulators of pesticides all over the world.

SESSION 1: Summary of the State of the Art: dsRNA based Product Use in Agriculture

Objective

The first session provided a background on the molecular mechanism of RNAi and relevant related pathways, reviewed the current understanding of cross-kingdom RNAi, examined the species-specificity of these dsRNAs on non-target species and discussed challenges related to the RNAi-efficiency in insects.

Speakers
 

The second session dealt with the research to date that investigated the factors that affect insects’ responsiveness to environmental dsRNA, covered approaches to assess biodegradation of dsRNA in different matrices and explored the role of certain technology to predict genetic changes and the impact in terms of efficacy of the RNAi products in target pests. It also summarised the published literature related to dietary uptake of external dsRNA in humans and addressed the lessons learnt from human therapeutic use of dsRNA.


DAY 2 - 11 April 2019

SESSION 2: Summary of Regulatory & Risk Assessment Experience with dsRNA-based Products

Objective

The third and final session focused on how problem formulation can guide risk assessments for spray applications of pesticides containing dsRNA, and considered potential pathways and testable risk hypotheses in the context of environmental risk assessment. It also covered the experience of experts involved in the risk assessment of genetically-modified crop plants, which incorporate the machinery to synthesise RNA molecules specifically directed against a pest species feeding on the crop (so-called ‘plant-incorporated protectants’, or PIPs).
