Black Sigatoka (Mycosphaerella fijiensis Morelet) disease is the greatest limiting factor affecting banana crop production across the world. The pathogen´s severity has reached epidemic levels and is exacerbated by the cultivation of monocultures and genetically uniform clones. In Colombia, losses occur in the exporting regions of Uraba and Magdalena, where its management depends on the use of agrochemicals, without achieving eradication. In the search for methods to reduce the pathogen’s effect within the banana zone of the departamento del Magdalena, Colombia, the relationship between climate, soil properties, and the presence of the disease was determined. Were utilized data from geographic informational systems, digitalized the data from the soil variables reported in the soil study conducted by IGAC (2009), records from weather stations in the region, and data showing the incidence rate of the pathogen. As a result of the study were established three areas (high, medium and low incidence rate) and discovered a positive correlation between the incidence rate of the disease with precipitation (r = 0.56), interchangeable magnesium, Mg+2 (r = 0.45), microporosity (r = 0.40), clay content (r = 0.54), and evaporation (r = 0.51). Were observed that there are soil conditions that influence the presence of the disease, variables that should be kept in mind in the management of banana cultivation.
