available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

Introduction
This document has been developed to provide guidance for a consistent approach to justify the claims
associated with the use of plant biostimulants in agriculture.
The definition of plant biostimulants to be used in the regulation on fertilizing materials 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 should never be considered to guarantee effectiveness
under all conditions, as many factors may 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. This document is applicable to all application types of plant biostimulants in agriculture.
