    The Western Ghats of India, recognized as one of the world's eighth "hottest hotspots" of biological diversity. Trichoderma, a well-known biocontrol agent, was explored from this hotspot. A total of 260 Trichoderma spp. isolates were studied, with 9% exhibiting strong biocontrol potential and crop growth-promoting activity. The study identified three novel isolates-Trichoderma caribbaeum var. caribbaeum, Trichoderma lixii, and Trichoderma brevicompactum-reported for the first time from the Western Ghats. Molecular characterization, based on ITS-rRNA and tef-1α gene sequence analysis, identified major isolates as T.koningiopsis, T. asperellum, T. caribbaeum var. caribbaeum, T. lixii, T. brevicompactum, T. atroviride, and T. erinaceum. Seed biopriming with the effective Trichoderma strain TR11 reduced the maydis leaf blight disease index to 32.92% and improved plant growth promoting attributes in maize. Defensive enzyme activities were increased 2.5 to 4.2-fold in various treatments with the TR11 isolate, along with enhanced lignification postpathogen inoculation, indicating strengthened plant defense mechanisms. The promising strain Trichoderma brevicompactum-TR11 produces secondary metabolites, among them 5% were found having role in biocontrol activity such as octadecanoic acid, palmitic acid-TMS, 5-(4-Deleted: Bioprospecting Trichoderma spp. from the 35
