Trichoderma and Its Role in the Biological Control of Plant Pathogenic Fungi

Abstract

Trichoderma is one of the beneficial fungi that has been recognized 
as an effective biological control agent for managing fungal diseases 
of plants. Owing to its rapid growth, enzyme production, and strong 
competitive ability, it can suppress the growth of several important 
plant pathogenic fungi, including Fusarium, Rhizoctonia, Botrytis, 
and Pythium. Trichoderma reduces disease severity through 
multiple mechanisms, including mycoparasitism, antibiosis, and the 
activation of the plant's defense system. The aim of this article is to 
review the use of Trichoderma as an alternative approach for 
controlling plant fungal pathogens. The paper discusses the 
effectiveness of Trichoderma, its different species, the mechanisms 
involved in the biological control of plant pathogenic fungi, and 
other related aspects. The information presented will contribute to 
promoting the application of Trichoderma as a biological control 
agent, thereby reducing dependence on chemical fungicides and 
minimizing adverse effects on sustainable agriculture, human 
health, and the environment.
