The EPPO Panel on General Standards on Efficacy Evaluation met at the EPPO Headquarters in Paris, on 2014-02-25/26. The meeting focussed on two proposed new General Standards and on revisions of a number of published EPPO General Standards.
The following PP1 General Standards were considered:
- Evaluation of the influence of tank mix adjuvants on the efficacy of Plant Protection Products (new) which was considered ready to be presented to the Working Party on Plant Protection Products;
- Efficacy considerations and data generation when making changes to the chemical composition of Plant Protection Products (new) which is still under study by the Panel;

In several other existing General Standards the reference to the repealed Directive 91/414/EEC was updated.
The Panel also discussed other important topics including the conclusions and recommendations from the EPPO Workshop on Experiences with implementation of zonal evaluation of plant protection products (Sofia, 2013-10-22/24).
Three new examples of zonal efficacy evaluations were studied:
- Clarification of efficacy data requirements for the authorization of an insecticide against aphids, thrips and whiteflies in ornamental plants in greenhouses in the EU 14;
- Clarification of efficacy data requirements for the authorization of a fungicide for the control of yellow rust (Puccinia striiformis f. sp. tritici (PUCCSI) on wheat (Triticum aestivum (TRZAX)) in the European Central authorization zone;
- Clarification of efficacy data requirements for the authorization of a fungicide for the control of fungal diseases in pome fruit (apple MABSD and pear PYUCO) across the four EPPO zones.
The afternoon of the second day of the meeting was dedicated to discussions about the EPPO codes. These discussions were part of a joint meeting with the ad hoc Panel on Harmonization of data on plant protection products.
