PP 1/271 (3) Guidance on efficacy aspects of comparative assessment

Specific scope Plant protection products ( PPP ) may be subject to a process of comparative assessment ( CA ) to determine whether substitution by alternative PPP s or other control methods is possible. Substitution should only be made if, among the other alternatives, there are no significant economic or practical disadvantages. This Standard provides guidance and a decision support scheme to determine whether the substitution of a PPP is appropriate in view of agronomic considerations. This includes practical and economic impacts of identified alternatives (both chemical and non‐chemical), as well as resistance risk management. The Standard does not address comparative safety from the human and environmental perspective (for EU Member States, guidance is available covering human health and environmental aspects of CA: ‘Draft Guidance document on Comparative Assessment and Substitution of Plant Protection Products in accordance with Regulation (EC) No 1107/2009 SANCO/11507/2013 rev.12, 10 October 2014’. SANCO 11507/2013 recommends a stepwise approach with the agronomic assessment conducted first, for which specific reference is made to using this EPPO Standard. Expert judgment is required in answering the questions (which may include the need to seek specialist advice). Specific approval and amendment First approved in 2011‐09. Minor revision approved in 2015‐09 (to harmonize requirements with DG SANCO Guidance Document 11507/2013. Revision approved in 2019‐09 following discussion in the EPPO Workshop on Comparative Assessment of Plant Protection Products (Lisbon, 2018‐10‐24/25)
