OECD Working Party on Pesticides

  • Assists member countries to develop and implement innovative tools for testing, assessment and management of pesticides;
  • Facilitates the optimal use of resources by providing a forum for identifying and overcoming obstacles to work sharing;
  • Assists in minimising non-tariff barriers in the trade of pesticides by aligning data requirements and assessment approaches.

Survey of Regulators and GJRs

GRJs are a potential mechanism to enhance registration of minor uses

8

Advantages:

  • Better understanding of other regulators
  • Increased collaboration
  • Harmonised residue definitions
  • Harmonised MRLs

Disadvantages:

  • Differences in timeframes
  • Different processes and results
  • Labour-intensive
  • Challenges with finding common GAP

Survey of Regulators and GJRs

  • Collaboration can reduce burden on regulators
  • Participation dependent on capacity and funding
  • Wider participation requires manufacturers to be proactive in seeking GJR partners
  • Other regulatory mechanisms can also deliver outcomes for MU
    • Data sharing
    • Extrapolation
    • Crop grouping
    • Regulatory incentives

9

    • International data
    • Reduced data requirements
    • Reduced fees
    • Bridging to existing uses

Improvements to GJRs

  • Same formulation and GAP are essential
  • Close alignment of assessment procedures and timeframes
  • Better coordination and communication
  • Improvements in data bridging (e.g., include as many uses as possible in single submission)
  • Increase extrapolation possibilities for residues
  • Accept broader range of trials from other countries

Conclusion

  • OECD Pesticide Programme works to streamline the process of pesticide approval and registration
  • Pesticides and pest management practices continue to evolve
    • Opportunities and challenges
  • Addressing challenges in a harmonised way creates a level playing field for industry and generates savings for industry and regulatory authorities alike
