European foreword
This document (prEN 17700-1:2023) has been prepared by Technical Committee CEN/TC 455 “Plant
biostimulants”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede CEN/TS 17700-1:2022.
prEN 17700-1:2023 includes the following significant technical changes with respect to
CEN/TS 17700-1:2022:
— Addition of some definitions;
— Addition of a model of check form in Annex B.
This document has been prepared under a Standardization Request given to CEN by the European
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;
— Part 4: Determination of quality traits, resulting from the use of a plant biostimulant;
— Part 5: Determination of availability of confined nutrients in the soil or rhizosphere.

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.

1 Scope
This document specifies the general principles for justifying the product claims for plant biostimulants.
It is applicable to all application types of plant biostimulants.
General principles consist of and define all general parameters, requirements and quality criteria, and
are intended to be applied in order to assess the efficacy of trials used for claim(s) validation as a result
of the use of a plant biostimulant.
This document is aimed primarily at manufacturers, laboratories, researchers, technical centres,
companies that will put the products on the market, notifying authorities, notified bodies, and market
surveillance authorities.
