Crynodeb:Banana cultivation is currently affected by many pests and diseases that decrease the production, but the etiology of some of them is unknown. One of the problems at the postharvest level is Banana finger rot disease, which is attributed to being caused by fungi, bacteria and nutrient deficiencies. The objective of the present work was to identify, morphologically characterize and evaluate five commercial products as a control alternative to the fungal pathogen found in banana fingers at the post-harvest level. After its isolation and pathogenicity tests, identification keys were used to determine its morphology. The morphological identification for fungi is somewhat limited since there are various microorganisms with similar characteristics. Morphological identification for fungi is somewhat limited and more complex than it appears to be, since there are several microorganisms with similar characteristics. Observing the macro and microscopic characters with their respective in vitro tests, it was possible to determine that the possible causal agent belongs to the genus Fusarium. Once the pathogen had been morphologically identified, its growth was studied in vitro with five commercial products (Copper, Cuprospor, Primebact Plus, Timorex Gold and Progranic Mega) in low, medium and high doses according to the manufacturer's recommendations. A completely randomized design with 16 treatments in three repetitions using the ANOVA and subsequent Tukey test at 95 % probability, evaluating the percentage of inhibition and number of spores for each experimental unit. The Copper product in high concentration presented an inhibition percentage of 88.8 % and an approximate concentration of 335 111 spores per ml, on the other hand, Cuprospor in high concentration obtained an inhibition percentage of 85.5 % and a concentration of 630 222 spores per ml, these being two superior treatments in growth inhibition compared to the control.
