What Story saw in the orchard in Polk County, Fla., wasn’t an anomaly. It’s the new norm in the Sunshine State, where about half the trees in every citrus orchard are stricken with an incurable bacterial infection from China that goes by many names:
huanglongbing, “yellow dragon disease” and “citrus greening.” Growers, agriculturalists and academics liken it to cancer. Roots become deformed. Fruits drop from limbs prematurely and rot. The trees slowly die.
The bacteria is spread by a tiny, invasive bug, also from China, called Asian citrus psyllid. It acquires the bacteria while feeding on the leaves of infected trees, then transmits it when feeding on healthy trees — akin to the way mosquitoes transfer malaria…
Even those who are optimistic about a scientific breakthrough say that if the infection continues unabated for another decade or so — admittedly a worse-case scenario — Florida’s $9 billion citrus industry could be destroyed.
