As early as I can remember I have always loved orange juice with breakfast and throughout the day. Like many Americans in the morning ,orange juice is a colorful and healthy way to stay on top of a cold, and away from the expensive doctor.
Could you imagine a breakfast without orange juice? Well I couldn’t, but it may be in the horizon. A disease called citrus greening has been seen in Florida. Citrus greening (Candidatus Liberibacter asiaticus) is a bacteria disease that is not harmful to humans but will kill and decline the production of a tree in as little as 5 years. This disease is not treatable once the tree has it. According to the University of Florida, citrus greening is found in Asia, Africa, Indian subcontinent, Brazil, and the United States.
The disease causes the fruit to become smaller, and have a green tint even when ripe. Also, according to APHIS, it also causes leaves to turn yellow, blotchy mottling, poor flowering, and dieback. The spread of the disease is done by Asian citrus psyllids when they feed on the leaves or stems, says APHIS. Other host plants include grapefruit and lemon, and limes.
Diseases are spreading from country to country every year. I don’t want to see a morning or go a hot afternoon without some lemonade or orange juice, and I think the rest of America can say the same. If you want to help, APHIS says to please look up citrus greening and the psyllids and if you are in Florida, or other states with citrus and you see symptoms contact your local USDA office.
