A History of Citrus Greening

Citrus greening originated in China nearly a century ago and impacts oranges, as well as grapefruit, lemons, and limes. Today, citrus greening is threatening groves around the world including Florida, California and Brazil.

Citrus Greening was first confirmed in Miami, Florida in 2005 and the disease spread rapidly, creeping up the Florida peninsula. By June 2006, twelve counties in Florida were confirmed to be afflicted with the disease. Today, a reported 80% of orange trees in Florida are now affected and it is estimated by the end of the growing season, nearly every orange growing region in the U.S. will be impacted by the disease.
