Biostimulant

Biostimulants also termed as plant conditioners or bioeffectors are substances, cultures of micro-organism, and mixtures of materials used to promote the growth of crop plants and can include natural or artificial plant growth regulators and biofertilizers. They do not include pesticides or fertilizers. The concept has been developed on the basis of the idea that plants are not isolated entities but grow within a complex ecosystem involving interactions with multiple organisms and that the strengths of these associations can be modified to enhance plant growth. The definitions vary but an attempted standard definition includes the statement that they are “a formulated product of biological origin that improves plant productivity as a consequence of the novel or emergent properties of the complex of constituents, and not as a sole consequence of the presence of known essential plant nutrients, plant growth regulators, or plant protective compounds.”
