RESUMO

The main objective of this work is the development of a mathematical model for spatial spot’s dispersion that presents a colonies coalescence process whith non regular boundary. For to describe this dynamic, is employed the Fractal Geometry, which is adequate for to represent the irregular characteristics of the frontiers growth. In this work, the mathematical formulation for the model is argued based on the invasion process of a plant disease, particularly those that manifest as spot shape on the leaf surface that characterize the dispersion in small scale, associated with a long distance dispersal represented by its propagules. The biological examples that motivated this work can be found, specially in the invasions of phytopathologies in the shape of the leave lesion caused by some fungi class in large plantations.
