Locating trees infected with Xylella fastidiosa is required for the management of Pierce’s disease of grape and bacterial leaf scorch of shade trees. Currently the only reliable method for finding X. fasitidiosa-infected trees is to examine every tree in the areas of concerns. A common protocol for X. fasitidiosa disagnosis is to visually examine trees based on symptoms and test with enzyne-linked immunosorbent assay (ELISA). However, X. fasitidiosa diagnosis based on symptoms is often unreliable and it is cost-ineffective when the disease incidence is >1% because so many trees could show symptoms. In this paper, we present a new cost-effective sampling program to locate plants infected with X. fasitidiosa to locate plants infected with X. fasitidiosa by using ELISA, geographic information system, global positioning system, and remote sensing.
