Endophytic fungi protect and benefit the plants in a natural way. The objective of this paper was to determine the entophytic activity of the fungus Pochonia chlamydosporia var. catenulata (Goddard) Zare and Gams var. catenulata strain IMI SD 187 (KlamiC^®) and its effect on plant growth promotion of banana and plantain vitroplants. The ‘CEMSA ¾’ (AAB), ‘Pisang Ceilan’ (AAB), ‘FHIA-01’ (AAAB) and ‘FHIA-18’ (AAAB) cultivars were used. The vitroplants were transplanted to polypropylene trays and black polyethylene bags with bovine compost substrate, and they were then randomly distributed in the acclimatization area. Two applications were made with KlamiC^® (5,6 x 10⁵ clamidospores.vitroplanta^-1) The variables evaluated were the vegetative growth and the substrate and root colonization by the fungus, using a completely randomized experimental design with 70 repetitions per treatment with KlamiC^® and the absolute control without KlamiC^® for each cultivar. The data were analyzed by a simple analysis of variance followed by Fisher’s LSD test. A significant increase of growth was produced in the plants treated with KlamiC^® compared with the controls. Substrate and plant rhizosphere was colonized by the fungus, with a lower percentage in the cultivar ‘FHIA-18’ (AAAB) con 4,15 %
