SUMMARY Exploratory spatial analysis of corn blight Exserohilum turcicum (leonard and suggs) in strata leaf of corn, in Villa Mercedes, San Luis Spatial studies are necessary to determine the spreading characteristics of disease outbreaks, for example locations of the inoculum source, shape and directionality of a causal agent, and to establish management strategies. To know the effect of the host in the distribution and multiplication of corn "blight", Exserohilum turcicum Leonard and Suggs, they were spatially analyzed in different strata leaf blight epidemics with the SURFER® program. Epidemic curves were plotted and severity geointerpolativos maps were developed. The exploratory spatial analysis of epidemics showed an acropetal spatial distribution. The spread of the disease on the plant depends on the hybrid, witch will determine the appropriate management for disease. It is necessary to continue with studies that allow to obtain temporal and spatial epidemiological parameters for comparing epidemics and to provide management options for the disease

Keywords : Spatial distribution; Exserohilum turcicum; Geointerpolative maps.
