Workshop on Comparative Assessment of Plant Protection Products

Lisbon, 2018-10-24/25


The EPPO Workshop on Comparative Assessment of Plant Protection Products will be held on 2018-10-24/25 in Lisbon and it is organized in collaboration with the Directorate-General for Food and Veterinary of Portugal. The Workshop will start on Wednesday 24th of October at 09:00 and finish on Thursday 25th at 12:30, with an optional technical visit in the afternoon.



The Workshop is organized upon request from EPPO Member Countries concerned with the comparative assessment of plant protection products which contain an active substance that has been identified as a candidate for substitution according to Regulation EC 1107/2009 on the placing of plant protection products on the market.


This Workshop is a follow up of the EPPO Workshop on comparative assessment held in 2009 (view 2009 Workshop conclusions )  which looked at the efficacy related aspects and that recommended the preparation of an EPPO Standard on this issue. PP 1/271 Guidance on comparative assessment was then first approved in 2011 and revised in 2015.


The Workshop will provide an excellent opportunity to share experiences of applicants and EPPO countries on the implementation of EPPO Standard PP 1/271 as different approaches may have been developed at national level. The event will also reconsider the conclusions and recommendations from the previous Workshop and identify whether there are areas for further work or guidance in relation to the EPPO Standard.

The Workshop will be divided into a plenary session comprising introductory lectures from applicants and national authorities followed by breakout sessions divided into different groups.


The audience is expected to be composed of officials from national regulatory authorities, delegates from crop protection companies (including ECPA), consultant firms applying GEP trials and other stakeholders involved in the application or evaluation of comparative assessment. The number of participants will be limited to 100 and the organizers will try to ensure participation of all interested parties.

Further information and the Workshop programme will be posted at a later stage.


To better identify the current approaches on Comparative Assessment, a questionnaire has been sent to all EPPO Countries. The analysis of the result of the questionnaire will be presented at the Workshop.
