Evaluation Manuals
The Evaluation Manual is a technical instructions and gives information on assessment standards, assessment framework, and calculation models that are used to conduct the assessments.
Ctgb developed a special evaluation manual for Biopesticides; below you will find the EM for conventional PPP.
Evaluation Manual – version 2025-2 the latest version
The Evaluation Manual describes the assessment framework used by the Ctgb for the assessment of applications for authorization of plant protection products. Data requirements, risk assessment methodologies and approval criteria are discussed in the Evaluation Manual, which combines the collective context of laws and regulations, policies, and the guidance documents that describe the methodology for assessment of plant protection products and active substances. The Evaluation Manual presents the European evaluation framework, with an additional section on the national framework. Requirements related to Dutch specific elements are listed in the latter section.
The manuals are periodically updated in accordance with new legislation and guidances. They are published in English. In this version of the Evaluation Manual for each chapter a change log is added in which the adjustments in comparison to the previous version are disclosed. In the manuals reference is made to external sources by hyperlinks.
Version 2025-2, published March 2025
The National Parts of the Evaluation Manual Chapters Environmental fate and behaviour: fate and behaviour in water, and Ecotoxicology: Terrestrial ecotoxicology: Non target arthropods and plants have been amended. Reference is now made to the Environmental Activities Decree (EAD) instead of the Activity Decree (AD) due to the inclusion of the AD into the EAD per January 2024. The changes between AD and EAD in the area of PPP are policy neutral, which implies that no changes are made in the general rules for PPP (for instance the obligation of at least 75% spray drift reduction and the purification degree of greenhouse wastewater of at least 95%). The general conditions set for the use of PPP in the EAD are used as a basis for the authorisation procedure, especially with regard to the environmental exposure.
