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 is not to 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 are 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.

3.4
light stress
negative impact of light intensity and/or spectrum on the plant in a specific crop environment
EXAMPLE high irradiance or low irradiance, UV radiation3.5
mechanical stress
negative impact of a mechanical force on the plant or the root zone in a specific crop environment
EXAMPLE wind, hail, agricultural operations3.6
water stress
negative impact of water or high solutes concentrations (supra-optimal and sub-optimal water level) or
excessive transpiration on the plant in a specific crop environmentEXAMPLE drought, high air vapour pressure deficit, flooding
3.7
chemical stress
negative impact of chemicals (supra-optimal or sub-optimal chemical compounds or presence) on the
plant in a specific crop environmentEXAMPLE salt stress, mineral toxicity induced by heavy metals or excessive application of mineral nutrients,
adverse pH conditions, ozone stress, phytotoxic effects of xenobiotics3.8
xenobiotic
chemical substance found within an organism that is not naturally produced or expected to be present
within the organismEXAMPLE heavy metals, pesticides, ozone
4 Terminology of the claim
The type of claim(s) included in the Technical Specification can be addressed to one or more of the above
defined abiotic stress(es) – see 3.3 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
according to CEN/TS 17700-1:—.EXAMPLE “improve tolerance to drought stress on woody perennials”, “improve tolerance to cold stress on
tomato”---------------------- Page: 8 ----------------------

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...
