CONTROLLING THE SPREAD OF XYLELLA FASTIDIOSA, THE CAUSAL AGENT OF OLEANDER LEAF SCORCH, BY DISRUPTING VECTOR ACQUISITION AND TRANSMISSION
This report describes research which involved the development of a management strategy for Oleander Leaf Scorch (OLS), a devastating disease which is affecting and ultimately killing oleander plants, a mainstay of the California Department of Transportation (CALTRANS) right-of-way planting. The report documents experiments which focused on determining the impact of a soil-applied systemic insecticide Merit, on the transmission of a plant-pathogenic bacterium, Xylella fastidiosa, to oleander by the glassy-winded sharpshooter (GWSS). The research found that applications of Merit induced GWSS mortality on OLS-diseased and healthy oleanders. Results were inconclusive regarding the impact of Merit on the acquisition of the OLS bacterium from treated-infected oleanders, and its inoculation by infectious GWSS into treated-healthy oleanders.
