huanglongbing

Adversity isn’t a stranger to Florida citrus growers. Throughout Florida’s history of citrus production, producers have dealt with damages left in the wake of multiple hurricanes and freezes.

Larry Black is a fifth-generation citrus grower and general manager of Peace River Packing Company in Polk County, Fla. His family has been a part of the citrus industry for over a century, planting citrus trees when they settled in Fort Meade in 1852.

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.

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.

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!

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.

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.

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.

If you are like millions of other Americans, there’s a chance you have a citrus tree or two growing in your yard. As a residential citrus grower, it is very important to check your trees regularly for signs of disease.

A diseased tree in your yard may seem like no big deal; however, it can easily spread disease to other nearby trees and make its way to large commercial groves where significant damage can be done. 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.

With summer winding down and school starting soon, there’s just enough time for one last trip! No matter where your travels take you, be sure to bring back lots of photographs, souvenirs and memories—but one thing you don’t want to bring home with you is citrus.

Moving citrus may seem completely harmless, but it can come with huge consequences. One little tiny bug, the Asian citrus psyllid could be hiding on citrus fruit, trees, clippings or nursery stock. It can carry citrus greening disease, or Huanglong Bing (HLB), a certain death sentence for infected trees. Pests carrying the disease can spread it to healthy trees. Throughout the U.S. and abroad, millions of acres of citrus trees have already been destroyed.

It’s time to grab those gloves and get outside for some gardening!  April is not only a great time to plant citrus trees, but it’s also Invasive Plant Pest and Disease Awareness Month. Before wielding that shovel, take a few minutes to learn how to keep your trees healthy and prevent the spread of citrus disease.

Citrus greening disease, also known as Huanglongbing (HLB), is one of the most severe plant diseases in the world. The disease has devastated millions of citrus trees in the United States and now has the potential to eliminate the citrus industry.  Once a tree is infected with the disease, there is no known cure.
