Microbial inoculants consist of living microorganisms that when applied to seeds, plant surfaces,
or the soil form beneficial relationships with plants and aid in plant development. The effects of
these inoculants are almost as varied as the microbes themselves. Some facilitate nitrogen
fixation, others enhance nutrient uptake, reduce fertilizer demand or suppress pathogens by
competing with them for the same resources. Some networks of fungi even pass immune activation
signals from a stressed plant to neighboring plants.

Bacillus subtilis


One of the most heavily researched bacteria, Bacillus subtilis has over 200,000 identified strains.
Known to act as an antagonist against a wide variety of pathogens, including Fusarium, Pythium,
Rhizoctonia, Sclerotinia and even nematodes.

Bacillus licheniformis

This common soil bacteria can break down resilient proteins in plant residues. Research also
associates it with nematode suppression and plant hormone synthesis.

Bacillus thuringiensis

This naturally-occurring bacteria has been shown to produce a variety of proteins with insecticidal

Lactobacillus plantarum

This common bacterium, produces lactic acid and other compounds to suppress competing
microorganisms in its environment.

Trichoderma harzianum

This fungus can create a symbiotic relationship with plant roots, protecting against pathogens such
as Pythium and Fusarium.

Trichoderma longibrachiatum

This fungal strain acts as an antagonist against nematodes and other, disease-causing fungi.
Research indicates it may also have positive influence on plant nutrient uptake and hormone

Aspergillus spp.

Not all molds are bad. Some strains of Aspergillus produce enzymes that break down hard-to- digest
plant fibers, improving soil structure and organic matter, or releasing energy and nutrients for
improved feed efficiency in animals.
