EPPO Standards on efficacy evaluation of plant protection products: update of the PP1 database
The EPPO Standards for the efficacy evaluation of plant protection products (PP1) describe the conduct of trials carried out to assess the efficacy of plant protection products against specific pests. They are addressed to all institutions, official registration authorities, public institutes or private firms carrying out such trials. All PP1 Standards[1] are stored in a database: https://pp1.eppo.int
The database has now been updated with the new and revised Standards that were approved by EPPO Council in September 2020.

[1] General Standards (e.g. design, conduct, reporting and analysis of trials, phytotoxicity, effects on succeeding crops, analysis of resistance risk, minor uses) can be accessed free of charge. Access to specific Standards (e.g. aphids on potato, weeds in cereals) is provided for an annual fee. Subscriptions should be made directly online via the database.
