Trichoderma Biological Control Agent: Phylogeny to Formulation discusses the biology and physiology of Trichoderma, beginning with its discovery in nature and continuing through its application in industrial organic agriculture production. It highlights the features of Trichoderma enabling the reader to identify strains with the best parameters for a given scenario, and guide their preparation for commercialization as protective agents against fungal phytopathogens and biostimulators in particular plant crops. Trichoderma spp. is a filamentous rhizosphere fungi distinguished by its capacity to invade plant roots and induce resistance. Trichoderma filamentous rhizosphere fungi are a dominant component of numerous soil ecosystem mycobiomes and knowledge of Trichoderma's features, such as its secondary metabolic activity and the nature of its interactions with plants and other microbes, is important in identifying effective applications in agriculture. *Trichoderma Biocontrol Agent*'s coverage of both direct and indirect biocontrol capabilities against a vast array of soil phytopathogens make this book a valuable resource for researchers and academics seeking to improve their effective application in sustainable plant health and agriculture.
