The Panel discussed the preparation of Standards for conducting field trials to evaluate the efficacy of herbicides and plant growth regulators. The standard text used for Standards for herbicides was reviewed and a plan made to check if a revision of a number of adopted Standards on herbicides and PGRs was needed.

The Panel considered the following two draft General Standards of relevance to the Panel which were sent for country consultation after the Panel meeting:

  • General principles for the development of co-formulated mixtures of PPP;
  • Efficacy considerations and data generation when making changes to the chemical composition of PPPs.

The Panel finalized the proposal for EPPO Codes for groups of weeds and prepared a first proposal for EPPO Codes for PGR targets. These classifications, once finalized, will be presented to the EPPO Working Party on Plant Protection products for approval and integration into the EPPO Global Database.

The date for the next meeting for the Panel on Efficacy Evaluation of Herbicides and Plant Growth Regulators will be decided by the Working Party on PPP.
