are a diverse group of substances that can be applied to plants to achieve beneficial effects in terms of their growth, nutrition and tolerance to biotic or abiotic stresses, regardless of nutrient content.

Plants, like all living things, are not independent entities in their environments, but rather are both hosts and partners of micro-organisms: bacteria and fungi.

As a result of these external and internal associations, adaptations emerge that enable them to respond better to biotic and abiotic stresses. The purpose of biostimulants is to strengthen these associations and thus their crop protection role.

Examples of biostimulants include protein hydrolysates, seaweed extracts, silicon, chitosan, humic and fulvic acids, phosphite, mycorrhizal fungi, Trichoderma, plant growth promoting rhizobacteria (PGPR), etc.

As in the assays to evaluate the effect on greenhouse plants described previously, we conduct studies to demonstrate the role of different biostimulant formulations.

Other tests are also carried out to detect effects on beneficial micro-organisms and biotic or abiotic stresses, such as improved tolerance to salinity and water stress. These qualities are highly appreciated in biostimulants.
