An Individual-Based Spatial Epidemiological Model for the Spread of Plant Diseases by Cendoya, Martina, Navarro-Quiles, Ana, López-Quílez, Antonio, Vicent, Antonio, Conesa, David

“…Almond leaf scorch disease, caused by the bacterium Xylella fastidiosa, was used as a case study to test the behavior of the model parameters and the variability due to the characteristics and location of initial disease introduction using a proposed simulation algorithm. The greatest variability in the results depended on the range parameter of the Matérn correlation, i.e., the distance at which two observations can be considered spatially uncorrelated, and the initial introduction. …”
