The apocalypse is on its way – at least for oranges. Citrus greening, a disease that kills citrus trees and makes their fruit green, shrunken and inedibly bitter, is racing across the globe. The disease, which is transmitted from tree to tree by a tiny insect called a psyllid, was first reported in China in 1943. Since then, it’s spread across the globe, finally making its way to Florida’s famous orange groves in 2005.
There is no known cure. A worldwide search failed to turn up a naturally immune tree. Measures like burning infected trees and dousing the psyllids with insecticide slow but do not stop the disease. With such seemingly bleak odds, does this mean the end of oranges, lemons and grapefruits?
