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.

The Asian Longhorned Beetle has killed more than 100,000 trees since it was accidentally introduced to this country about 20 years ago.
USDA APHIS is deeply involved with mitigating invasive pest issues, along with State and local governments. Invasive pests cost the U.S. an estimated $120 billion each year in damages to our environment, agriculture, and native species. The five invasive species described here are a few of the damaging invasive pests of concern to the Animal and Plant Health Inspection Service. You can help detect these pests and take actions to reduce their spread. Read more »
If you have citrus trees growing near you, check them out and help Save Our Citrus!
Do you have a citrus tree in your backyard? From afar it may look fine, but when was the last time you took a close look? Your tree could be hiding all kinds of clues about its health. Here are a few resources to hone your citrus sleuth skills!
Checking your citrus tree regularly is extremely important to prevent the spread of citrus disease. Four serious citrus diseases found in the United States include: Huanglongbing (also known as citrus greening or HLB for short), citrus canker, citrus black spot and sweet orange scab. These diseases are a threat to the health of U.S. citrus, and finding them early is critical. That’s why we need your help! Read more »

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. It’s no longer as simple as packing it up and shipping it, or buying a citrus tree at a road side stand to bring home.
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 »
Mary Palm, Ph.D., who is leading USDA’s multi-agency response to combat Huanglongbing (citrus greening) disease.
When I learned I was chosen to lead USDA’s new emergency, multi-agency response framework to combat one of the most serious citrus diseases in the world, I felt both humbled and honored. I relish the opportunity as a scientist to partner with other federal agencies, states, and industry to combat a disease—huanglongbing (HLB or citrus greening)—that has devastated so many citrus groves in Florida and threatens other citrus-producing states.
When Secretary Vilsack established this new framework—USDA’s HLB Multi-Agency Coordination (MAC) Group—he directed us to fund the most promising, practical research to give growers tools to use against HLB as quickly as possible. USDA provided $1 million in funding, and the 2014 Federal budget includes an additional $20 million for HLB research, which the Group will collectively determine how best to spend. Read more »
If you are sending citrus gifts, learn how to do it responsibly by visiting www.saveourcitrus.org
Out with the snake, in with horse! January 31 marks the start of the Chinese New Year. Many people will be enjoying the rich cultural traditions of this holiday such as food, parades and exchanging gifts. One traditional Chinese New Year gift is citrus fruit, such as mandarin oranges and tangerines. This fruit is said to bring luck, wealth and prosperity.
However, without proper precautions citrus can also bring something else that may not be so favorable—the Asian citrus psyllid. This pest carries citrus greening disease, also known as Huanglongbing (HLB), a disease threatening the commercial citrus industry and homegrown citrus trees alike. Although it is not harmful to humans or animals, the disease is fatal for citrus trees and has no known cure. Read more »
