Abstract: The objective of this work was to evaluate the ability of Trichoderma spp. to promote growth of common bean plants and to reduce severity of anthracnose (Colletotrichum lindemuthianum), as well as to identify the best performing isolates. Sixty Trichoderma spp. isolates were evaluated as to their capacity to promote growth in common bean. The seven isolates that stood out were added to the culture substrate and assessed for reduction in severity of anthracnose in bean plants treated with C. lindemuthianum conidia. The most efficient isolates in controlling the disease were identified by DNA sequencing. The IB 28/07 isolate was evaluated in the concentrations 0.5, 1, 1.5, and 2% (weight:volume), which reduced disease severity in 41.51, 55.15, 81.82, and 96.06%, respectively. The most efficient Trichoderma spp. isolates can promote increases above 30% in dry matter production and reduce disease severity between 63 and 98%. These isolates were identified as belonging to the species Trichoderma harzianum, T. strigosum, and T. theobromicola.
