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 not 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.

5 Justification of plant biostimulant claims regarding abiotic tolerance
5.1 Introduction
In open field conditions it can be difficult to fully control specific abiotic stress factors due to their
inherent variability and due to the fact, that, often several abiotic stresses may be present at the same
time (combinational stresses). Therefore, to fully validate an abiotic stress tolerance claim with both a
negative (untreated and unstressed) control and a positive (untreated and stressed) control it should
take place under controlled conditions (e.g. growth chamber, growth room, greenhouse).
In controlled conditions or where a negat
