Plant biostimulants - Claims - Part 3: Tolerance to abiotic stress resulting from the use of a plant biostimulan
This EN specifies the guidelines to justify the claims of tolerance to abiotic stress resulting from the use of a plant biostimulant as defined by the FPR.
The revised Regulation on fertilising products (EC) Nr 2019/1009 includes a new PFC for plant biostimulants (PFC 6). For these products, it is obligatory to provide the information about the effects claimed for each target plant and any relevant instructions related to the efficacy. Appropriate definition and scope about the claims of ‘tolerance to abiotic stress’ and their agronomic markers are necessary to check the conformity of CE marked plant biostimulants with the requirements of the Regulation. The tolerance to abiotic stress resulting from the use of a plant biostimulant need to be standardised in the framework of the SReq
The proposed EN will allow the industry to demonstrate compliance to the requirements in the FPR while helping governments and competent authorities to monitor effectively compliance of the products. Consumers and environmental stakeholders will profit from the well-established uniform and reliable control of plant biostimulants applied to soil and crops.

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.

4 Terminology of the claim
The type of claim(s) included in the European Standard can be addressed to one or more of the above
defined abiotic stress(es) (see 3.5 to 3.7).
For instance, a plant biostimulant can improve plant tolerance to a single abiotic stress factor such as
heat stress or to multiple abiotic stress factors such as heat stress and salt stress in one or more target
crop(s).
Label shall clearly indicate that the plant biostimulant is addressed to improve tolerance to abiotic stress
with a clear indication of the type of abiotic stress(es) and the crop(s) on which the effect is demonstrated
