- 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.
