What benefits of Trichoderma viride have been cited in the scientific literature?
Seven categories of benefit are cited for Trichoderma viride in the peer-reviewed literature. Biocontrol studies report that T. viride suppresses mycelial growth of Fusarium culmorum, F. cerealis, Botrytis cinerea, and Colletotrichum sp., and reduces soybean root rot disease index by approximately 15%—findings relevant to growers evaluating Trichoderma viride for biological disease suppression or as a fungicide alternative.
Research on Trichoderma viride biostimulant potential cites phosphorus solubilization of insoluble inorganic and organic phosphorus fractions, with increased phosphorus content measured in inoculated seedlings. The same literature reports seedling growth promotion—gains in aboveground dry weight, root morphology, chlorophyll fluorescence parameters, and photosynthetic pigment content.

2Potential claims from the literature
Reported to solubilize insoluble inorganic phosphorus and mineralize insoluble organic phosphorus, increasing phosphorus content in inoculated plant seedlings
Reported to suppress mycelial growth of fungal pathogens including Fusarium culmorum, F. cerealis, Botrytis cinerea, and Colletotrichum sp., and to reduce soybean root rot disease index by approximately 15%
Reported to inhibit biosynthesis of the mycotoxins deoxynivalenol (DON), nivalenol (NIV), and zearalenone (ZEN) produced by Fusarium species, and to convert ZEN into its hydroxylated derivative β-zearalenol
Reported to promote plant seedling growth, including increases in aboveground dry weight, root morphology, chlorophyll fluorescence parameters, and photosynthetic pigment content
Dual inoculation of T. viride with dark septate endophytes reported to enrich beneficial rhizosphere microbiota and alter soil nutrient status under drought stress, potentially supporting cultivation of medicinal plants in dryland conditions
Reported to form common endophyte networks connecting plant root systems and transfer amino acid-derived carbon resources from donor plant soil to receiver plant tissues
Reported to participate in enhanced degradation of polycyclic aromatic hydrocarbons (PAHs) through positive synergistic interactions with plant-growth-promoting rhizobacteria in co-culture
