“…Moreover, Trichoderma has the ability to prime plants against subsequent attacks by pathogens. Concerning biotic stress, several plants species showed the increased resistance to pathogen attack when pretreated with Trichoderma like cotton, common bean, tomato, cucumber, pepper, lettuce, maize, and rice (Rebolledo-Prudencioa et al 2020). Different Trichoderma strains can also induce protective effects against different pathogensas presented in Table 3.…”

“…It is reported also that, chlorophyll and water contents in both leaves and roots increased significantly in wheat plants inoculated with T. longibrachiatum under salinity stress conditions. Its deference mechanism may take place through stimulating antioxidant activities of the plant defense enzymes i.e., catalase (CAT), peroxidase(POD) and superoxide dismutase (SOD), enzymes compared to wheat-untreated plants (Rebolledo-Prudencioa et al 2020). Under drought stress, it is common the reduction in plant content of chlorophyll and carotenoids as well as the severe damage in maize membrane; however, this damage can be avoided when maize inoculated with T. atroviride ID20G.…”

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.

“…The colonization of roots results in physical or biochemical responses, initiating chemical transmission, in which plants produce secondary metabolites (SM), constituting limiting factors for the invasion of the fungus in the cortical cell layers in the roots [ 19 ]. According to the barriers imposed by plants, Trichoderma fungi can produce strategies to “dribble” plant responses; this occurs via hormone production to establish a prolonged mutualistic association without the occurrence of obstacles that can make the root establishment and the symbiotic process unfeasible [ 10 ].…”

Forest production has great relevance in the Brazilian economy, characterized by several production sectors, including the production of seedlings. With the focus on maximizing the capacity of survival, development, and adaptation of seedlings, Trichoderma is highlighted as a potentially useful genus of microorganisms for promoting growth and higher product quality. In this sense, this review aims to describe the main mechanisms of fungi action in forest seedlings’ production. The different species of the genus Trichoderma have specific mechanisms of action, and the current scenario points to more advances in the number of species. The interaction process mediated by different mechanisms of action begins in the communication with plants, from the colonization process. After the interaction, chemical dialogues allow the plant to develop better because, from colonization, the forest seedlings can maximize height and increase shoot and root development. Fungi promote solubilization and availability of nutrients to seedlings, which show numerous benefits to the development. The use of beneficial microorganisms, such as fungi of the genus Trichoderma, has become a sustainable strategy to enhance seedling development, reducing the use of agrochemicals and industrial fertilizers.

“…can exert mycoparasitism, as well as the production of metabolites with antagonistic activity (De la Cruz‐Quiroz et al., 2019; Sridharan et al., 2020), siderophores (Zhao et al., 2020) and cell wall degrading enzymes (Manzar et al., 2021). In addition, this endophytic fungus works as a symbiont, favoring plants' development and increasing their resistance to biotic and abiotic stress (Rebolledo‐Prudencio et al., 2020). It can activate the induced systemic resistance response, the accumulation of proteins, the generation of reactive oxygen species, the development of lignifications, and the production of phytoalexins (Meshram et al., 2019).…”

In the present work, the evaluation of the use of Trichoderma spp. for controlling different phytopathogens of agricultural importance (Fusarium oxysporum, Rhizoctonia solani, Sclerotinia sclerotiorum, Botrytis cinerea, Colletotrichum gloeosporioides, and Phytophthora sp.) was carried out. Confrontation assays by dual culture, volatile metabolites (overlapping plate assay), and diffusible metabolites (poison medium assay) were performed to identify and select the Trichoderma strain with a greater spectrum of inhibition and the most sensitive phytopathogen. The production of hydrolytic enzymes associated with biological control by the Trichoderma sp. Trs GT2 strain (chitinase, cellulase, amylase, and lipase) was evaluated. Subsequently, the use of solid‐state and submerged fermentation to produce extracts with antagonistic activity against B. cinerea was evaluated, and the production of specific activity β 1–3 glucanase was compared. It was found that Trichoderma sp. Trs GT2 presented the greatest spectrum of inhibition against the phytopathogens evaluated, resulting in the strain of B. cinerea being the most sensitive microorganism to its effects (percentages of inhibition: dual culture 100%, volatile metabolites 100% and diffusible metabolites 28.24%). The Trichoderma sp. Trs GT2 strain showed amylase, cellulase, and chitinase activity. It also produced activity titers β 1–3 glucanase of 13.22 U/g by solid‐state fermentation (SSF) and 8.19 U/mL by submerged fermentation, as well as specific activities of (1.38 U/mg) and (14.23 U/mg), respectively. The extracts produced by both fermentation systems did not present an antagonistic effect against B. cinerea; this can be attributed to the need for interaction with the phytopathogen in question for the induction of metabolites with antagonistic activity, as well as to the confusion that the evaluation of the antagonistic effect of diffusible metabolites, through the cellophane paper technique, can generate in which the mechanism of nutrient competition can cause the inhibitory effect. This work shows that the ability of one microorganism to exert biocontrol against another can vary depending on the mechanism through which it performs and demonstrates that the antagonist‐phytopathogenic interaction can promote the production of metabolites with antagonistic activity.
