The bacterium that causes Pierce’s disease (PD) (Xylella fastidiosa) is transmitted to grapevines by the glassy-winged sharpshooter GWSS. Insecticides were evaluated for efficacy and residual activity against GWSS on grapevines and in citrus. Results from field trials indicate that pyrethroids and neonicotinoids are promising control agents against immatures and adults. Preliminary results indicate that the chitin inhibitor IGR, buprofezin, controls immatures. Information on efficacious and environmentally compatible chemical control is needed to develop integrated pest management to protect California vineyards from PD. Also, information is needed to develop insecticide resistance management within crop management production systems.
