Currently, plant pathogens and pests pose a serious threat to agriculture, causing significant losses in food production and nutritional value. Conventional crop protection methods based on the use of synthetic pesticides to combat these phytopathogens have developed resistance and residue problems, leading to the contamination of soil and water ecosystems. Therefore, eco-friendly methods have gained momentum in sustainable agriculture because of their dual role as biopesticides and biofertilizers. Among the different species of fungi that are widely utilized as biocontrol agents and biofertilizers, Trichoderma is often exploited as a biocontrol agent against a wide range of pest and pathogen populations. Trichoderma species of the genus Trichoderma produce numerous bioactive compounds, including cell wall-degrading enzymes and secondary metabolites, with antifungal properties against a diverse range of phytopathogens. Trichoderma can protect plants and retain microbial populations under different soil conditions and is marketed as a formulation for biofertilizers, soil amendments, and biopesticides. Several species of Trichoderma are well-known mycoparasites, in which one fungus is killed by another. However, few of these species can antagonize other organisms such as plant parasitic fungi, nematodes, and plant pests, making this fungus a versatile biocontrol agent. Recent case studies on Trichoderma species have demonstrated that their integration into different cropping systems enhances plant growth via nutrient uptake, development of plant resistance, and improved soil health through rhizospheric interactions. This dual functionality is particularly relevant in the context of climate change and contributes to sustainable agricultural strategies.
