Citrus Farmers Facing Deadly Bacteria Turn to Antibiotics, Alarming Health Officials

A pernicious disease is eating away at Roy Petteway’s orange trees. The bacterial infection, transmitted by a tiny winged insect from China, has evaded all efforts to contain it, decimating Florida’s citrus industry and forcing scores of growers out of business.
