“…In particular, chitinase was the most highly correlated hydrolytic enzyme, emphasizing its relevance for biocontrol of FG. This result is consistent with the hypothesis that Trichoderma sp., are able to repress pathogen through synchronization of mycoparasitism and antibiotic production [22,34,35]. Finally, we detected 70 different chemical compounds in T. asperellum ZJSX5003.…”

The efficacy of seven strains of Trichoderma asperellum collected from the fields in Southern China was assessed against Fusarium graminearum (FG) the causal agent of corn stalk rot of maize were in vitro for their antagonistic properties followed by statistical model of principal compound analysis to identify the beneficial antagonist T. asperellum strain. The key factors of antagonist activity were attributed to a total of 13 factors including cell wall degrading enzymes (chitnase, protease and b-glucanases), secondary metabolites and peptaibols and these were analyzed from eight strains of Trichoderma. A linear regression model demonstrated that interaction of enzymes and secondary metabolites of T. asperellum strain ZJSX5003 enhanced the antagonist activity against FG. Further, this strain displayed a disease reduction of 71 % in maize plants inoculated with FG compared to negative control. Pointing out that the T. asperellum strain ZJSX5003 is a potential source for the development of a biocontrol agent against corn stalk rot.

“…Hyperparasitism and volatile metabolites may be involved in the inhibition of Fusarium oxysporum, Rhizoctonia solani and Botrytis cinerea [22]. Cell wall degrading enzymes (CWDEs) such as chitinase, glucanase, and proteases are thought to be closely related to the mycoparasitism of Trichoderma strains [18, 23,24]. Inhibitory volatile substances such as alkylpyrons may also contribute to the biocontrol activity of some Trichoderma strains [25][26][27].…”

Trichoderma spp. are widely used as bio-fungicides in agriculture. Induction of plant defense and mycoparasitism (killing of one fungus by another) are considered to be the most important mechanisms of Trichoderma-mediated biological control. In the present study, Mycoparasitism for the three tested pathogens. Moreover, one hundred eighty five (185) isolates were also showed inhibitory but their antagonistic potential <50% of the mycelial growth while 50 isolates showed <40% mycelial growth of F. oxysporum, 61 isolates showed <50% mycelial growth for R. solani and 3 isolates showed <50% mycelial growth for B. cinerea. These potential isolates of Trichoderma may be further exploited as a biocontrol agent against F. oxysporum, R. solani and B. cinerea as well as other soilborne phytopathogenic fungi.

“…Trichoderma-derived cell wall degrading enzymes and fungal metabolites from T. asperellum CCTCC-RW0014 have a synergistic inhibitory effect to control fungal pathogen Fusarium oxysporum f. sp. cucumerinum [17]. It is well-known that several oligosaccharides from fungal cell wall components stimulate phytoalexin secretion and lignin or callose formation in plants [19,20].…”

Fungal cell wall oligosaccharides are being focused on the biological management of crop diseases by elicitation of defense responses. In the present study, an approach was taken to enhance the pearl millet disease resistance using biotic elicitors for eco-friendly management against downy mildew pathogen through seed priming approach. Crude oligosaccharides extracted from four different Trichoderma spp. enhances the disease protection ability in pearl millet. Seed priming with T. asperellum along with the osmopriming agent, mannitol had shown better protection with improved seedling vigor compared to controls. Modulation of defensive enzymes such as peroxidase and lipoxygenase also confirms the elicitation of resistance responses in the host with increased enzyme activity at different time interval patterns.
