“…Concerning the fresh mass of shoot and roots, treatments with T. asperellum on substrate infestation presented higher fresh matter when compared to treatment with F. oxysporum and control, which could be justified by fungi of the genus Trichoderma, as well as excellent agents of biological control, also act as promoters of plant growth (SILVA et al, 2007;MILANESI et al, 2013;ZACHOW et al, 2016). Some Trichoderma species are able to increase the root system surface and improve nutrient availability, and in conjunction with it, increase plant growth, crop production and resistance to some diseases, enhancing the plants ability to resist abiotic stresses (HARMAN et al, 2004;LUCON, 2009;LIU et al, 2016). For the use of beneficial microorganisms, such as Trichoderma spp., to be effective, it is necessary to know the biological interaction capacity of these agents, since they exert multiple effects on the colonized plant, including the action of secondary metabolites produced by Trichoderma species (VINALE et al, 2008).…”

The increase in flower cultivation in recent years has been reflecting the higher incidence of soil pathogens that can cause serious problems. This study aimed to evaluate the biological control of Fusarium wilt in gerbera with Trichoderma asperellum. The evaluated treatments were: T1) Control, only sterile substrate; T2) Substrate + Fusarium oxysporum; T3) Substrate + Fusarium oxysporum + Trichoderma asperellum; and T4) Substrate + Trichoderma asperellum. For this, the pathogen was isolated from gerbera with disease symptoms and, subsequently, it was identified according to morphological characters. Furthermore, the degree of antagonism of T. asperellum against F. oxysporum was evaluated through the culture pairing test. For greenhouse evaluations, commercial autoclaved substrate was used and infested with corn grains infected by the pathogen. Morphological identification confirmed the pathogen species as Fusarium oxysporum. In the culture pairing test, it was found that T. asperellum did not present a high degree of antagonism. The plants cultivated on substrate infested by the pathogen had no visible symptoms of wilt, but the substrate infestation with the pathogen provided lower values of fresh and dry mass of shoots and roots. The treatment with T. asperellum obtained higher values of fresh and dry mass of both shoots and roots, and also more vigorous inflorescences in relation to the plants treated with the pathogen

“…are well-known as plant growth-promoting fungi, which could enhance the plant uptake of nutrients, producing plant growth hormones and protecting cultivated plants from pathogen infection . Several studied emphasized the role of Trichoderma as a biofertilizer in vegetable crop production such as tomato (Khan et al 2017;De Palma et al 2019;Sani et al 2020), cucumber ) and cabbage (Liu et al 2016;Ji et al 2020).…”

T HE world's burgeoning population faces a great challenge concerning food security, which could be achieved through different sustainable agricultural practices. Trichoderma, as a ubiquitous fungus, is one of the most promising microorganisms that might offer several avenues for sustainable agriculture. Trichoderma spp. may guarantee a better solution for conventional problems in agriculture through several approaches including the protection of cultivated plants from undesirable abiotic and biotic conditions under changing environments and promoting their growth in poor or limited soil nutrients. The promising role of Trichoderma for vegetable production as a biocontrol and biofertilizers has been confirmed but its role as a plant pathogen still needs more studies. Trichoderma could inhibit or suppress the growth of soil phytopathogens, promoting plant growth and soil health, through activation of many mechanisms including synthesis of antibiotics, mycoparasitism and competition for nutrients and space against plant deleterious microorganisms. The sustainable approaches of Trichoderma including biofortification, bio-remediation and phyto-remediationas well as exploring future research opportunities will be also addressed in this work.

“…Recently, the focus on the role of SMs in this process is increased because of the discoveries of several metabolites with the same growth-promotion effect. Among SMs described as elicitors of plant growth, 6-PP, peptaibols, harzianolides, and polyketide chrysophanol are known (Liu et al, 2016, Zeilinger et al, 2016Mukherjee et al, 2013;Vinale et al, 2008a).…”

“…In fact, European Commission has approved fi ve species as biopesticides: Trichoderma atroviride (strain IMI 206040, T11, AGR2, I-1237, SC1); Trichoderma asperellum (strain ICC012, T25, TV1 and T34); Trichoderma gamsii (strain ICC080); Trichoderma harzianum (strain T-22 and ITEM 908); Trichoderma polysporum (IMI 206039) [http://ec.europa.eu/food/plant/ pesticides/eu-pesticides-database]. However, Trichoderma-plant and Trichoderma-phytopathogenic fungus interactions are much more complex, mainly because they involve not only the direct effect of hydrolytic enzymes, but also the role of secondary metabolites (SMs) (Vinale et al, 2008b;Liu et al, 2016;Alwhibi et al, 2017;. SMs are numerous heterogeneous groups of compounds, which are not essential for survival but are supposed to have functions in signalling and defense (Mukherjee et al, 2013).…”

“…This volatile organic compound with the aroma of coconut is produced by T. atroviride (Druzhinina et al, 2011). Another group of SMs, polyketides, are also known as molecules that have the role in signalling, such as chrysophanol, member of a subgroup of anthraquinonons (Liu et al, 2016). They are synthesized by polyketide synthases; one of them, encoded by the gene pks4 is responsible for green pigmentation of conidia .…”

This work was focused on the characterization of novel isolate of Trichoderma atroviride O1, found in the forest around the village of Zázrivá (the Northern Slovakia, region Orava). The isolate was identified by sequencing its internal transcribed spacer (ITS) region of rDNA. T. atroviride O1 stimulated the development of lateral roots of model plant Lepidium sativum. Simultaneously, the isolate has proved its high mycoparasitic potential as it displayed the ability to attack colonies of phytopathogenic fungi (Alternaria alternata, Fusarium culmorum, Botrytis cinerea). This isolate produced secondary metabolites, which were isolated and tested for the antimicrobial activity against gram-positive bacteria Staphylococcus epidermidis and Staphylococcus aureus. The growth of these bacteria was suppressed to 10 % and 40 %, respectively. The suppression of the growth of two Candida species was also strong (10 % growth). However, growth parameters of three phytopathogenic fungi (Alternaria alternata, Botrytis cinerea and Fusarium culmorum) were less affected (75 % growth in comparison with the control). Attempts were made to characterize secondary metabolites isolated from T. atroviride O1. Known peptaibols, 20—21 amino acid long, but also shorter peptides, were detected by MALDI-TOF mass spectrometry. Thus, this study demonstrates the plant growth promotion, strong mycoparasitic potential and antimicrobial activity of the isolate T. atroviride O1, which could be in part ascribed to the production of secondary metabolites. This isolate does have a potential in the biocontrol in eco-farming. Further study, particularly, the identification of produced secondary metabolites, is needed.
