“Current Applications of Trichoderma in Agriculture Biocontrol of Fungal Pathogens And Enhancement of Plant Growth”

Abstract

Filamentous fungi of the genus Trichoderma, commonly found in the rhizosphere, are a prevalent component of various soil ecosystem mycobiomes and are known for their ability to colonize plant roots. Understanding Trichoderma's characteristics, including its metabolic activity and interactions with plants and other microorganisms, is crucial for its effective application in agriculture. Interest in Trichoderma is growing due to its direct and indirect biocontrol capabilities against a wide spectrum of soil-borne phytopathogens. These fungi employ a range of complex mechanisms, such as mycoparasitism, degradation of pathogen cell walls, competition for nutrients and space, and activation of plant defence responses. Given the continuous threat posed to plants by various pathogens, particularly filamentous fungi, and the increasing resistance of these pathogens to chemical pesticides, there is a pressing need to develop alternative biological protection strategies. Among non-pathogenic microorganisms, Trichoderma stands out as a promising candidate for sustainable agricultural practices due to its extensive biofertilization and bio stimulatory properties. Most Trichoderma species function as plant growth-promoting fungi, capable of producing phytohormones and the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase. This review consolidates current knowledge on the role of Trichoderma, emphasizing its significance in promoting plant growth and its effectiveness in the biocontrol of fungal phytopathogens.
