Citrus has always been synonymous with Florida.
The orange adorns the state license plate. The University of Florida's famed football stadium was named after an orange magnate. There is even a county called Citrus.
Throughout the decades, the citrus industry has always stood strong — through freezes, hurricanes and rampant development.
But now the $9 billion industry is facing its biggest threat yet, putting at risk the state's economy but also its very identity. Blame a mottled brown bug no bigger than a pencil eraser that carries a lethal disease.
In China, where the problem was first discovered, it's called huanglongbing. Translation: "the yellow dragon disease." In Florida, it's known simply as "greening."
It arrived here via an invasive bug called the Asian Citrus Psyllid, which carries bacteria that are left behind when the psyllid feeds on a citrus tree's leaves. The tree continues to produce useable fruit, but eventually disease clogs the vascular system. Fruit falls, and the tree slowly dies. The psyllid isn't native to Florida, but it is believed to have arrived from someone who perhaps unknowingly brought a slip of a tree from Asia. Some think it then spread on the winds of hurricanes a decade ago. There is no cure for greening, and no country has ever successfully eradicated it.
All of that has Florida's growers in a frenzy to find a way to stop it. Nearly all of the state's citrus groves are affected in varying degrees by greening disease, and researchers, growers and experts agree that the crisis has already started to compromise Florida's prominence as a citrus-growing region. Florida is second in the world, behind Brazil, in growing juice oranges, producing about 80 percent of juice in the U.S.
This past growing season, the state produced 104 million boxes of oranges, which comprise the bulk of Florida's overall citrus crop. In 2003, two years before greening was discovered and prior to several devastating hurricanes, 243 million boxes were picked...
