The document summarizes the initial and current economic effects of Pierce's Disease (PD) in California, which is spread by the Glassy-winged Sharpshooter (GWSS). Initial losses to grape growers were from removing infested vines and were estimated at $46 million. A public containment program was established involving quarantines and treating GWSS in citrus groves. Current economic effects include grape and citrus growers treating vineyards and groves, with costs reimbursed. While treatment costs are lower than vine removal, the containment program and consumer price increases impact taxpayers and consumers.
