Introduction
The European Committee for Standardization (CEN) was requested by the European Commission (EC) to
draft European Standards or European Standardization deliverables to support the implementation of
Regulation (EU) 2019/1009 of 5 June 2019 [1] laying down rules on the making available on the market
of EU fertilising products (“FPR” or “Fertilising Products Regulation”).
This standardization request, presented as SR M/564 and relevant amendments, also contributes to the
Communication on “Innovating for Sustainable Growth: A Bio economy for Europe”. The interest in plant
biostimulants has increased significantly in Europe as a valuable tool to use in agriculture.
Standardization was identified as having an important role in order to promote the use of biostimulants.
The work of CEN/TC 455 seeks to improve the reliability of the supply chain, thereby improving the
confidence of farmers, industry, and consumers in biostimulants, and will promote and support
commercialisation of the European biostimulant industry.
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 in Regulation (EU) 2019/1009 [1] is claims-based. For this reason,
demonstrating that a product is indeed a bona fide plant biostimulant depends on a demonstration of its
function.
The placement 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 can be applied in multiple ways: to the soil, on plants, as seed treatment, etc.
This document is applicable to all application types of plant biostimulants.
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 rules.
IMPORTANT — It is absolutely essential that tests conducted in accordance with this document be
carried out by suitably trained staff.
1 Scope
This document gives guidance on a consistent approach to justify the claims associated with the use of
plant biostimulants.
This document is aimed primarily at manufacturers, laboratories, researchers, technical centres, and
companies that intend to place plant biostimulants on the market, as well as notifying authorities, notified
bodies, and market surveillance authorities.
To be in compliance with this standard, it is important to also follow the recommendations and quality
criteria described in the standard EN 17700-1:2024 on general principles to demonstrate plant
biostimulant claims.
