Commission and the European Free Trade Association.
The EN 17700 series, Plant biostimulants — Claims, consists of the following parts:
— Part 1:General principles;
— Part 2: Nutrient use efficiency resulting from the use of a plant biostimulant;
— Part 3: Tolerance to abiotic stress resulting from the use of a plant biostimulant;

Introduction
This document has been developed to provide guidance for a consistent approach to justify the claims
associated with the use of plant biostimulants.
The definition of plant biostimulants to be used in Regulation (EU) 2019/1009 is claims-based. For this
reason, demonstrating that a product is indeed a bona fide plant biostimulant depends on a
demonstration of its effect.
The placing of a plant biostimulant on the market does not guarantee effectiveness under all conditions,
as many factors can influence the performance of a plant biostimulant in the field.
Plant biostimulants used in agriculture can be applied in multiple ways: on soil, on plant, as seed
treatment, etc.
WARNING — Persons using this document should be familiar with normal laboratory practice. This
document does not purport to address all of the safety problems, if any, associated with its use. It is the
responsibility of the user to establish appropriate safety and health practices and to ensure compliance
with any national regulatory conditions.
IMPORTANT — It is absolutely essential that tests conducted in accordance with this document be
carried out by suitably trained staff.
