Saving Florida’s Citrus Industry Through Collaboration and Innovation

Thermotherapy trucks cover infected citrus trees with a canopy to heat treat them significantly reducing the amount of disease in the trees and increasing their productivity.

The Florida citrus industry is under siege and the invader is a tiny bug called the Asian citrus psyllid (ACP).  The ACP spreads a disease known as Huanglongbing (HLB) or citrus greening, and together they are destroying groves that have been cultivated by families for generations.

But all is not lost.  USDA’s Animal and Plant Health Inspection Service (APHIS) is working closely with State and Federal partners such as the Agricultural Research Service and National Institute of Food and Agriculture, as well as State departments of agriculture and the citrus industry in Florida, California, Arizona and Texas to develop short-term solutions to help protect groves while researchers focus on longer-term projects that may one day put an end to this devastating pest and disease combo.

Soon, citrus producing states across America, including Arizona, California, Florida, Louisiana and Texas, will be full of fresh citrus. But gone are the days of sharing the fruit trees or seeds with friends and family out of state or even in the next county.

You’ve heard the saying “move it or lose it.” When it comes to citrus trees, it’s “Move It AND Lose It.” When you move citrus trees, you risk losing America’s citrus altogether – think breakfast with no fresh oranges, grapefruit or even juice. Read more »

Out with the snake, in with horse! January 31 marks the start of the Chinese New Year.

Although it is not harmful to humans or animals, the disease is fatal for citrus trees and has no known cure. Read more »

If citrus disease were to spread out of control, it has the potential to destroy the entire U.S. citrus industry, causing the loss of billions of dollars and millions of jobs. Read more »
