摘要

The primary objective of modern agriculture is to improve farming practices with a strong emphasis on sustainability. Trichoderma species are recognized for their potential to benefit crops through both direct and indirect mechanisms. This review examines the diversity and ecological versatility of Trichoderma spp., highlighting key biocontrol mechanisms, including competition for space and nutrients, mycoparasitism, production of bioactive compounds, and the induction of plant defense mechanisms against phytopathogens. Special emphasis is placed on how abiotic and biotic factors modulate the metabolic pathways involved in the synthesis of antifungal secondary metabolites. Understanding these regulatory mechanisms is crucial for optimizing the application of biocontrol strategies, such as Trichoderma-based ones, under field conditions to advance their integration into sustainable agricultural systems. Trichoderma strains and their metabolites have demonstrated effective control over fungi, nematodes, and other pathogens across diverse crops in both greenhouse and field settings. Furthermore, interactions with other beneficial microorganisms or agrochemicals have enhanced disease suppression and crop performance. Challenges remain regarding formulation stability, field efficacy, and large-scale production and combination of metabolites. Future directions include the use of autochthonous strains, the design of synthetic microbial communities, the application of metabolic engineering, as well as the combination of two or more strategies.
