Fungi from the genus Trichoderma have been extensively studied and used as biological control agents (BCAs) because of their versatile mechanisms of action. These include triggering systemic resistance, directly inhibiting pathogens, promoting plant growth, enhancing tolerance to abiotic stress, and producing auxins. However, the widespread application of the most studied Trichoderma strains has been limited by discrepancies between their potential results observed in controlled environments and the outcomes in greenhouses and field conditions. These differences are associated with context dependency, influenced by strain-specific traits, crop genotype, soil properties, and environmental factors. In this review, we examine the mechanisms of action, current challenges, and opportunities, emphasizing the importance of local strategies and detailed characterization of native strains to boost the effectiveness of Trichoderma-based products in sustainable agriculture.
