A unique effort from growers, administrators, policy makers and researchers are working on a solution for this immense X. fastidiosa threat.
No cure has been found, but the understanding of Xylella fastidiosa and glassy-winged sharpshooter biology has markedly increased since 2000, when the California Department of Food and Agriculture, in collaboration with different universities, such as University of California, Davis (UC Davis); University of California, Berkeley; University of California, Riverside, and the University of Houston–Downtown started to focus their research on this pest.
The research explores the different aspects of the disease propagation from the vector to the host plant and within the host plant, to the impact of the disease on California's economy.
All researchers working on Pierce's disease meet annually in San Diego in mid-December to discuss the progress in their field.
All proceedings from this symposium can be found on the Pierce's disease website, developed and managed by the Public Intellectual Property Resource for Agriculture (PIPRA).

There are no resistant Vitis vinifera varieties, and Chardonnay and Pinot noir are especially sensitive, but muscadine grapes (Vitis rotundifolia) have a natural resistance.
Pierce's disease is found in the southeastern United States and Mexico.
Also it was reported by Luis G. Jiménez-Arias in Costa Rica, and Venezuela, and possibly in other parts of Central and South America.
There are isolated hot spots of the disease near creeks in Napa and Sonoma in northern California.

Work is underway at UC Davis to breed PD resistance from Vitis rotundifolia into Vitis vinifera.
The first generation was 50% high-quality vinifera genes, the next 75%, the third 87% and the fourth 94%.
In the spring of 2007, seedlings that are 94% vinifera were planted.
