Post-hurricane Analysis of Citrus Canker Spread and Progress towards the Development of a Predictive Model to Estimate Disease Spread Due to Catastrophic Weather Events

Fig. 13. Example of the application of WRIVs to post-storm discoveries of citrus canker in Hardee County. (A) WRIVs were calculated for hurricanes Charley, Frances, and Jeanne in a "blowing from" orientation.  (B) The predominant vector indicated that canker infection was likely in a NNW direction. CCEP personnel then inspected a grove planted with a susceptible cultivar in line with the predominant WRIV and were able to identify a new citrus canker infection.
