Antagonistic fungi belonging to the Trichoderma family are the most frequent active ingredients of biological preparations all over the world due to their multifunctional activity in the soil. Theoretical mode of action of Trichoderma active ingredients are the next:

•    Antibiotics production against plant pathogen organisms.
•    Mycoparasitic ability to attack other fungi (plant pathogens) mycelia. Trichoderma hyphae growing surround of other fungi mycelia, penetrate and feed from them.

•    Elicitor effect of Trichoderma treatments is known that may cause induced systemic resistance of the host.
•    Saprophytic competition means colonization of the niche before other (plant pathogen) fungi.
•    Secondary metabolites production for plant regulation by plant hormones and hormones like chemicals.
•    Trichoderma species are able to alter nutrients for the plants (Mn4+® Mn2+, Cu2+® Cu1+, Fe3+® Fe2+).     
•    Trichoderma species are able to decompose phytotoxins produced by plant pathogen fungi.
