In this Tuesday, June 17, 2014 photo, citrus trees affected by a disease called "greening" are burned in a grove owned by the Hunt Bros. Cooperative in Lake Wales, Fla. The Hunt family owns 5,000-plus acres of groves and is part of the co-op that contributes to Florida's Natural, the third largest juice brand in the country. Florida's $9 billion citrus industry is facing its biggest threat yet by a tiny invasive bug called the Asian Citrus Psyllid, which carries bacteria that are left behind when the psyllid feeds on a citrus tree's leaves.
