ABSTRACT=<p><italic>Trichoderma</italic> is mainly used to control soil-borne diseases as well as some leaf and panicle diseases of various plants. <italic>Trichoderma</italic> can not only prevent diseases but also promotes plant growth, improves nutrient utilization efficiency, enhances plant resistance, and improves agrochemical pollution environment. <italic>Trichoderma</italic> spp. also behaves as a safe, low-cost, effective, eco-friendly biocontrol agent for different crop species. In this study, we introduced the biological control mechanism of <italic>Trichoderma</italic> in plant fungal and nematode disease, including competition, antibiosis, antagonism, and mycoparasitism, as well as the mechanism of promoting plant growth and inducing plant systemic resistance between <italic>Trichoderma</italic> and plants, and expounded on the application and control effects of <italic>Trichoderma</italic> in the control of various plant fungal and nematode diseases. From an applicative point of view, establishing a diversified application technology for <italic>Trichoderma</italic> is an important development direction for its role in the sustainable development of agriculture.</p>
