Microorganisms, natural partners for plants

Plants are naturally colonized by billions of microorganisms. Some of them have beneficial effects on their host plant through both direct and indirect mechanisms.

Lallemand supplies high quality products, composed of beneficial microbes or microbial derivatives, which enhance plant health and productivity.

Symbiotic microorganisms: feed, stimulate and protect your crops.

Phyllosphere, Rhizosphere and endosphere




The phyllosphere refers to the total above-ground portions of a plant. It hosts diverse communities of microorganisms that form the phyllobiome.

The phyllobiome acts to mitigate abiotic stresses and to protect the plant from diseases and invertebrate pests.




The rhizosphere is the region of the soil in contact with the roots of a plant. It is a highly favourable habitat, in which there can be up to 10 billion microorganisms in each gram of soil. This rhizobiome plays an essential role in regulating nutrition, growth, disease and invertebrate pests.




Endophytes are symbiotic microorganisms that live within a plant. These endophytes enhance host growth and nutrient acquisition, improve the plant’s ability to tolerate abiotic stresses, and enhance resistance to invertebrate pests or plant pathogens.
