Spraying Antibiotics to Fight Citrus Scourge Doesn’t Help, Study Finds

The study, published last week in the journal Phytopathology, found that spraying the drug oxytetracycline on trees had no detectable impact on the bacterial disease know as citrus greening that slowly kills orange and grapefruit trees

Citrus greening has led to a 70 percent drop in citrus production across Florida since the pathogen first arrived from Asia in 2005.
