 Defining plant biostimulants : aiming at a
consensus
 Regulation of plant biostimulants
 Difference between biostimulants and biofertilizers
 Challenges
 Apportunities

4. INTRODUCTION
 “Materials that, in minute quantities, promote plant
growth” (1997, Zhang and Schmidt)
 “Biostimulants are materials, other than fertilizers,
that promote plant growth when applied in low
quantities” (Kauffman, 2007)
 European biostimulant industry council
 Biostimulant coalition, USA

5. HUMIC SUBSTANCES
 Sources:
 Organic matter
 Composts & vermicompostes
 Mineral deposits
 Agricultural by-products
 Soil fertility
 Root nutrition
 Respiration
 Stress protection
 Hydroponically grown maize

6. PROTEIN HYDROLYSATES & N-
CONTAINING COMPOUNDS
 “Amino acids and peptides mixtures are obtained by chemical
and enzymatic protein hydrolysis from agro-industrial by-
products, from plant and animal source”
 Betaines, polyamides, non-protein amino acids
 Anti-stress properties
 TCA cycle
 Antioxidant activities
 Microbial biomass and activity
 Soil reparation
 Soil fertility

7. SEAWEED EXTRACTS & BOTANICALS
 20 seaweed products
 Growth promotion
 Gel formation
 Water retention
 Soil airation
 Fixation and exchange of caton
 Fixation of heavy matels
 Soil microflora

8.  Seed germination
 Hormonal effects
 Botanicals:
 Food ingredients
 Plant protection products
 Allelochemicals

9. INORGANIC COMPOUNDS
 Chemical elements that promote plan growth and may be
essential to particular taxa ,but are not required by all plants
 MAIN ELEMENTS
i. Al
ii. Co
iii. Na
iv. Se
v. Si
 Complex bio stimulants like extract of seaweeds and
animal waste
 Inorganic salts of beneficial elements

10. BENEFICIAL FUNGI
 Mycorrhizal fungi
 Arbuscule forming mycorrhiza (AMF)
 Rhizobacter
 Metagenomics
 Fungal based products
 Fungal entophytes like trichoderma SPP.

11. BENEFICIAL BACTERIA
 Bacteria interact with plants in all possible ways
 Mutualism and parasitism
 Bacterial niches
 Participation to the biogeochemical cycles
 Main bio stimulants
 Mutualistic endosymbiosis of the type rhizobium
 Mutualistic rhizospheric PGPRs (plant growth promoting
rhizobacteria )

16. REGULATION OF PLANT BIOSTIMULANTS
 Very complex
 Difference between biostimulants, bio fertilizers, soil
improvers
 Route for regulation in Europe
 National regulation on fertilizers(fertilizers rout)
 European pesticide law
 Plant protection products (PPPs)

17. MARKET OF BIOSTIMULANTS
 Market data is scarce
 Limited reliability
 Regulatory status diverse
