USDA Funds $30M to Fight Citrus Greening

USDA Targets Citrus Greening with Promising Tools and Long Term Solutions

Agriculture Secretary Tom Vilsack announced $30 million in funding TODAY for 22 projects to help citrus producers combat Huanglongbing (HLB), also known as citrus greening, a devastating citrus disease that threatens U.S. citrus production. The money will fund promising projects that could offer near-term solutions as well as research funding that may develop long-terms solutions. The promising near-term tools and solutions are funded through the HLB Multiagency Coordination Group while the research projects are funded through the Specialty Crop Research Initiative Citrus Disease Research and Education (CDRE) program, which is made available through the Agricultural Act of 2014 (Farm Bill).

“Our HLB Multi-Agency Coordination Group has worked closely with the citrus industry to select and fund projects that we think will make a real difference for growers against HLB,” said Vilsack. “Funding these projects through cooperative agreements puts us one step closer to putting real tools to fight this disease into the hands of citrus growers.” Vilsack continued, “Through the CDRE research we are announcing today, we are also investing in long-term solutions to diseases that threaten the long-term survival of the citrus industry.”

USDA’s HLB Multi-Agency Coordination Group funded fifteen projects that support thermotherapy, best management practices, early detection, and pest control efforts for a total of more than $7 million. All of them are designed to provide near-term tools and solutions to Agriculture Secretary Tom Vilsack announced $30 million in funding TODAY for 22 projects to help citrus producers combat Huanglongbing (HLB), also known as citrus greening, a devastating citrus disease that threatens U.S. citrus production. the citrus industry fight HLB. The projects include:

Two projects to provide improved delivery of thermotherapy to HLB infected trees, a promising treatment that has shown to help infected trees regain productivity after treatment. One of these projects will test thermotherapy on a grove-wide scale. since studies have shown heating a tree to 120 degrees for approximately 48 hours can kill the HLB bacterium in the upper part of the tree, allowing the tree to regain productivity. This funding will address the challenge of identifying a quick and practical way for growers to use the technology on a large scale.

Six projects to provide citrus producers with best management practices in Florida citrus groves.

One project will focus on lowering the pH of the irrigation water and soil to strengthen the root systems of citrus trees to help them better tolerate HLB infection.
Three projects will support different combinations of integrated management approaches for sustaining production in trees in different stages of infection.
Two projects will test strategies for preventing tree death due to HLB infection. One of those will field test rootstocks that have shown ability to tolerate HLB infection. The other will use technologies to rapidly propagate the tolerant material for field use by the industry.

Three projects to increase early detection of HLB.

One project will train dogs to detect HLB infected trees. Detector dogs have proven to be highly adept at detecting citrus canker and early results suggest they will be an effective early detection tool for HLB.
One project will develop a root sampling and testing strategy.
One project will compare several promising early detection tests.

Four projects to provide tools to kill the Asian citrus psyllid (ACP), the vector of HLB.

One will produce and release the insect Diaphorencyrtus aligarhensis as a second biological control agent in California.
One project will use a biocontrol fungus to kill ACP adults.
One project will use a trap to attract and kill ACP adults.
One project will increase the use of field cages for the production of the insect Tamarixia radiata in residential areas, especially those that are adjacent to commercial groves in Texas. Tamarixia has already proven to be an effective biological control agent for ACP. Using field cages will enable the wider use of this effective ACP control.

In addition to these projects, USDA’s National Institute of Food and Agriculture funded more than $23 million dollars for research and education project to find lasting solutions to citrus greening disease. Examples of funded projects include developing HLB-resistant citrus cultivars, the development of field detection system for HLB, using heat as a treatment for prolonging productivity in infected citrus trees, creating a new antimicrobial treatment, among others. A fact sheet with a complete list of awardees and project descriptions is available on the USDA website.

Fiscal year 2014 grants have been awarded to two California universities, University of California, Davis, $4.6M and University of California, Riverside, $1.7M. The University of Florida, Gainesville and Kansas State University, Manhattan, are also receiving research awards.

CDRE is a supplement to the Specialty Crop Research Initiative (SCRI). The focus of this year’s funding was specifically on citrus greening disease. Because there are wide differences in the occurrence and progression of HLB among the states, there were regional as well as national priorities for CDRE. These priorities, recommended by the Citrus Disease Subcommittee, fall within four categories: 1) priorities that deal with the pathogen; 2) those that deal with the insect vector; 3) those that deal with citrus orchard production systems; and 4) those that deal with non-agricultural citrus tree owners.

One subcommittee member is Justin D. Brown, Vice President and General Manager, D Bar J Orchards, Inc. in Orange Grove, California.

The Farm Bill builds on historic economic gains in rural America over the past six years, while achieving meaningful reform and billions of dollars in savings for taxpayers. Since enactment, USDA has made significant progress to implement each provision of this critical legislation, including providing disaster relief to farmers and ranchers; strengthening risk management tools; expanding access to rural credit; funding critical research; establishing innovative public-private conservation partnerships; developing new markets for rural-made products; and investing in infrastructure, housing and community facilities to help improve quality of life in rural America.

ACP Quarantine Expands in Santa Clara County

ACP Quarantine Adds Another 61 Square Miles to the North

Announced TODAY, the Asian citrus psyllid or ACP Quarantine has expanded to include an additional portion of Santa Clara County following the detection of multiple psyllids in and around the City of San Jose.

The quarantine expansion adds 61 square miles to the north, bringing the total quarantine area to 160 square miles. A map is available online at: www.cdfa.ca.gov/plant/go/acp-quarantine. Residents with backyard citrus trees in the quarantine area are asked not to transport or send citrus fruit or leaves, potted citrus trees, or curry leaves from the quarantine area.

In addition to quarantines in portions of Santa Clara, Fresno, Kern, San Joaquin, and San Luis Obispo counties, ACP entire-county quarantines remain in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare and Ventura counties.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species, such as curry trees, are susceptible hosts for both the insect and the disease. There is no cure once a tree becomes infected, the diseased tree will decline in health and produce bitter, misshaped fruit until it dies. HLB has been detected just once in California – in 2012 on a single residential property in Hacienda Heights, Los Angeles County. This plant disease does not affect human health.

Residents in the area who think they may have seen ACP or symptoms of HLB on their citrus trees are urged to call CDFA’s Pest Hotline at 1-800-491-1899. For more information on the ACP and HLB, please visit: www.cdfa.ca.gov/go/acp.

ASIAN CITRUS PSYLLID QUARANTINE IN MADERA COUNTY

SACRAMENTO, January 7, 2015 – A portion of Madera County has been placed under Asian citrus psyllid quarantine for the following the detection of one ACP northeast of the City of Madera, in the Madera Lake area. The quarantine zone measures 100-square miles, bordered on the north by Road 603; on the south by Avenue 15; on the west by Road 26; and on the east by the Madera Canal. A link to the quarantine map may be found here: www.cdfa.ca.gov/plant/go/acp-qmaps.

The quarantine prohibits the movement of citrus and curry tree nursery stock out of the quarantine area and requires that all citrus fruit be cleaned of leaves and stems prior to moving out of the quarantine area. An exception may be made for nursery stock and budwood grown in USDA-approved structures that are designed to keep ACP and other insects out. Residents with backyard citrus trees in the quarantine area are asked not to transport citrus fruit or leaves, potted citrus trees, or curry leaves from the quarantine area.

ACP county-wide quarantines are now in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare, and Ventura counties, with portions of Madera, Fresno, Kern, San Joaquin, San Luis Obispo, and Santa Clara counties also under quarantine.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening.

BREAKING NEWS: Two New ACPs Found in One Trap Near Exeter

CDFA Has Saturated Exeter Area with Extra ACP Detection Traps

The Tulare County Agricultural Commissioner’s offices announed TODAY that two additional Asian citrus psyllids (ACP) have been detected on one trap south of the city of Exeter. The latest interceptions were confirmed by the California Department of Food and Agriculture (CDFA). Maps and current information are available on the Tulare County Agricultural Commissioner’s website.

CDFA has already begun to saturate the affected areas with detection traps in order to determine the extent of any infestation.The United States Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS) and CDFA will work collaboratively to determine what steps are taken next.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species are susceptible hosts for both the insect and the disease. There is no cure once a tree becomes infected. The diseased tree will decline in health,producing bitter, misshaped fruit untilitdies. To date, HLB has been detected on just one residential property in the Hacienda Heights neighborhood of Los Angeles.

Tulare County Ag Commissioner Marilyn Kinoshita said that her staff will continue to support the efforts of our $750 million citrus industry, as well as our residential citrus owners. “I want to emphasize that citrus fruit is safe to eat and the disease is not harmful to human health,” said Kinoshita.

Residents in the area who think they may have seen ACPs are urged to call CDFA’s Pest Hotline at 1-800-491-1899 or the Tulare County Agricultural Commissioner.

Media inquiries related to technical questions about Asian citrus psyllid and Huanglongbing (HLB) disease are encouraged to contact Katie Rowland, Account Coordinator for Nuffer, Smith, Tucker Inc. at (661) 817-3638.

The best way to fight HLB is to suppress the spread of ACPs which can carry it. So, California Citrus Research Board hired Nuffer, Smith, Tucker, (NST) a public relations firm, to raise awareness of ACPs and HLB, especially among the many California homeowners with backyard citrus trees who may unknowingly be harboring the pest, and to encourage the public to take necessary steps to save California citrus.

Research Targeting the ACP Olfactory System Shows Promise

A University of California Riverside Asian citrus psyllid (ACP) research team, led by Anandasankar Ray, associate professor of entomology, has found a new tool that targets the ACP olfactory system. The ACP olfactory system is sensitive to a variety of odorants (odor molecules) released by citrus plants; in fact the ACP depends on its sense of smell to identify its citrus hosts, and this discovery offers an opportunity to develop new attractants and repellents, according to Ray.

Anandasankar Ray, UC Riverside Associate Professor of Entomology

As reported in Entomology Today, Ray’s research has identified a blend of odorants found in nature, including myrcene, ethyl butyrate and p-cymen, that can lure ACPs to sticky traps. In the study, odor-based traps caught nearly 230 percent more ACPs than conventional traps placed on the same trees. “What’s particularly encouraging is that these three chemicals are affordable, useful in small quantities, and safe for human handling,” said Ray, with the potential of being developed into monitoring, masking and surveillance tools.

“We anticipate that this odor-based insect lure could be of use to growers in California and other parts of the world where ACP invasion is occurring,” Ray commented. “Our study also reports identification of odors that block the ACP olfactory system from detecting citrus odors and have potential for development into repellents.”

“Similar approaches can be taken to develop control strategies using odors for other insect pests of crops as well,” Ray explained. UCR has great strengths in insect chemosensory research ranging from chemical ecology to olfactory and gustatory neurobiology of behavior. With expertise ranging from very basic science to applied areas, several UCR collaborating laboratories are working to find ways to control insects that transmit diseases like West Nile virus and malaria, in addition to citrus greening disease. UCR discoveries have the potential to bring about a paradigm shift in controlling these diseases.

Study results on the lures were published in PLOS ONE, and the large-scale identification of odors detected by ACP was published in Chemical Senses.

ACP Quarantine Expands in Kern, Santa Clara Counties

By Laurie Greene; Cal Ag Today Editor

Following the detection of an Asian citrus psyllid (ACP) south of the City of Bakersfield in Kern County, an additional portion of Kern County has been placed under quarantine for the ACP. Likewise, following the detection of psyllids in the City of San Jose near Kelly Park, the first detection of ACPs in Santa Clara County and the Bay Area, a portion of northwestern Santa Clara County has been placed under ACP quarantine.

The additional Kern County quarantine zone measures 148-square miles in and around the City of Bakersfield, bordering on the north by New Stine Road; on the east by S Vineland Road; on the south by Millux Road; and on the west by Interstate 5.

The Santa Clara County quarantine zone measures 99-square miles, bordered on the north by Alum Rock Park; on the south by Santa Teresa Blvd; on the west by N Monroe Street; and on the east by Joseph D Grant County Park.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species, such as curry trees, are susceptible hosts for both the insect and the disease. Once a tree becomes infected, there is no cure; the diseased tree will decline in health and produce bitter, misshaped fruit until it dies.

Though the ACP is a dangerous pest of citrus, the fruit is safe to eat and HLB is not harmful to human health, according to Joe Deviney, Santa Clara County Agricultural Commissioner.

USDA’s free “Save Our Citrus” iTunes app

Residents in the area who think they may have seen ACP or symptoms of HLB on their citrus trees are urged to call CDFA’s Pest Hotline at 1-800-491-1899. Residents with backyard citrus trees in the quarantine area are asked not to transport citrus fruit or leaves, potted citrus trees, or curry leaves from the quarantine area. For more information on the ACP and HLB, please visit the CDFA website.

Better yet, if your citrus fruit is misshapen or discolored or your citrus tree looks sick, send a photo with the new, free SAVE OUR CITRUS app from the USDA. Residents can easily report symptoms, upload a photo and receive a response back from citrus experts. The app includes information and diagnostic tools for all four leading citrus diseases: citrus greening, citrus canker, citrus black spot and sweet orange scab.

Elsewhere in the state, ACP quarantines are now in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare, Ventura, and portions of Fresno, Kern, and San Luis Obispo counties.

The disease itself, HLB, has been detected just once in California, in 2012, on a single residential property in Hacienda Heights, Los Angeles County, and is known to be present in Mexico and in parts of the southern U.S. Florida first detected the psyllid in 1998 and the disease in 2005, but the two have spread to all 30 citrus-producing counties in the state. The University of Florida estimates HLB has caused the loss of more than 6,600 lost jobs, $1.3 billion in lost grower revenue and $3.6 billion in lost economic activity. The HLB disease is also present in Georgia, Louisiana, South Carolina, and Texas, and the ACP pest–but not the disease–detected in Alabama, Arizona, Hawaii, and Mississippi.

Asian Citrus Psyllid Quarantine Covers Tulare County Completely

UPDATE: The Asian citrus psyllid (ACP) Quarantine covers Tulare County, in its entirety, following the detection of two psyllids in the City of Tulare. The first ACP was detected in a trap in a residential neighborhood on September 10, in the City of Tulare. The second detection was on September 17, also in a residential setting within the City of Tulare. These detections, when added to previous detections elsewhere in the county, dictate that a county-wide quarantine is the most effective response to contain the pest. A map is available online at: www.cdfa.ca.gov/plant/go/acp-quarantine

The quarantine prohibits the movement of host nursery stock out of the quarantine area and requires that all citrus fruit be either cleaned of leaves and stems or treated in a manner to eliminate ACP prior to moving out of the quarantine area. Residents with backyard citrus trees in the quarantine area are asked to not remove fruit from the quarantine area.

In addition to quarantines in portions of Fresno, Kern, and San Luis Obispo counties, ACP entire-county quarantines remain in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, and Ventura counties.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species are susceptible hosts for both the insect and the disease. There is no cure once a tree becomes infected. The diseased tree will decline in health until it dies.

Inspections Underway in Central Valley for Huanglongbing, Asian Citrus Psyllid

On Alert for the Asian Citrus Psyllid

Source: Robert Rodriguez; The Fresno Bee

Armed with magnifying glasses and bug-sucking aspirators, state agriculture technicians are in Fresno, checking residential citrus trees for any signs of the Asian citrus psyllid and the tree-killing disease it can carry.

The psyllid poses one of the greatest threats to California’s nearly $2 billion citrus industry and officials want to keep it from gaining a foothold in the central San Joaquin Valley.

Inspectors will spend several weeks in the Fresno area and then move into Tulare County — the largest citrus producer in the state.

“We don’t want this disease here,” said Cora Barrera, a state technician. “It would be a disaster.”

Barrera recently checked several trees at a home near Fresno Pacific University in southeast Fresno. Using her magnifying glass, she looked for tell-tale signs on the tree’s leaves: dull orange-yellow nymphs and the waxy tubules that push honeydew away from their body. She also looked for adult psyllids that are about 1/8 of an inch and brownish.

When Barrera finds a psyllid, she catches the insect using an aspirator and drops it into a glass tube. Any bugs caught will be tested for the disease.

A team of about six state technicians, including Barrera, will visit thousands of homes in the city.

Jennifer Romero, an environmental scientist with the California Department of Food and Agriculture, said that so far no psyllids have been found nor any sign of the disease they carry, huanglongbing, also known as citrus greening.

Citrus farmers fear the disease because there is no known cure. Infected trees produce bitter-tasting fruit and eventually die. In Florida, the nation’s orange juice capital, the disease has caused $1.3 billion in lost revenue over the past several years.

So far, the disease has only been found in one residential tree in the Hacienda Heights area of Southern California. But the psyllids have spread throughout the region, and a massive quarantine prohibits the movement of citrus fruit and trees out of the area.

Despite the regulatory net, the bug has hitchhiked its way to the Valley, having been caught in insect traps in Fresno and Tulare counties. To keep the psyllid in check, farmers have sprayed their groves and the state has treated residential trees where the psyllids have been caught.

A quarantine also has been put in place that covers 870 square miles of the Valley’s citrus belt.

But all that still isn’t enough, experts say. One key lesson learned from Florida’s losing battle with the disease is early detection and prevention.

Door-to-door residential inspections have been used in Southern California since the discovery of the disease in 2012.

Using a method developed by U.S. Department of Agriculture scientist Tim Gottwald, the survey targets specific areas with potential risk factors. The factors are many, but include proximity to commercial citrus groves, roads used by trucks transporting citrus and flea markets.

Experts say citrus trees at flea markets and swap meets are sold without the benefit of government inspection and should be avoided.

So far, the state’s inspectors have surveyed more than 1,000 homes in Fresno and hundreds more remain.

Romero said fortunately for the inspectors most residents don’t mind the visits.

“We really have not had any problems and it helps that people are aware of the disease,” she said. “They also don’t want to lose their own trees.”

If the resident isn’t home, the state will leave an information sheet about the bug and disease and information for setting up a future home visit.

Gene Hannon, entomologist with the Fresno County Department of Agriculture, urged owners of citrus trees to be vigilant about checking their own trees. He also said that people should avoid bringing home any citrus from the Southern California area; buying citrus trees at flea markets; or grafting trees from Southern California or any other region with the disease.

“The more people are aware, the better able we are to keep this disease out of our area,” Hannon said. “We don’t want to have this problem.”

Everyone Plays a Part in Protecting California Citrus

Protecting California Citrus

By Victoria Hornbaker; Ag Alert

Recently, the U.S. Department of Agriculture released its final crop estimate for the Florida orange crop, reflecting a reduction of 30 million cartons in total production from the previous season. There is no denying the devastating impact that Huanglongbing has had on the Florida citrus industry since the disease was first discovered in 2005. A drive through Florida citrus country will offer vastly different scenery than that of California’s premier citrus-producing regions.

In some respects, the California citrus industry has been fortunate to learn from the situation in Florida and has taken a very proactive approach to protect itself from a similar fate. In 2009, the industry supported a mandatory self-assessment to fund a comprehensive treatment and trapping program to manage the insect carrier of HLB, the Asian citrus psyllid, and prevent HLB from taking hold.

The Asian citrus psyllid is now endemic throughout a majority of Southern California, particularly in dense, urban areas where citrus trees can be found in six out of every 10 backyards. In March 2012, HLB was discovered for the first time in a backyard citrus tree in Los Angeles County. Although there have not been any additional confirmed cases of HLB since then, as an industry we must remain vigilant statewide in order to protect our $2 billion citrus crop.

Currently, there are eight counties in California that are entirely quarantined for the Asian citrus psyllid: Imperial, Los Angeles, Orange, Riverside, Santa Barbara, San Bernardino, San Diego and Ventura. Additionally, portions of Fresno, Kern, San Luis Obispo and Tulare counties are also under quarantine for the Asian citrus psyllid.

The total quarantined area statewide is now 46,530 square miles. Maps are available online at www.cdfa.ca.gov/plant/go/acp-quarantine.

With a large portion of the state’s commercial citrus production now within quarantine zones, it is increasingly important that growers and packers are up to date on current regulations and protocols, to best manage psyllid populations and prevent the pest from spreading any further.

There are two approved options under the Bulk Fruit Movement Performance Standard available for commercial citrus growers and packers to comply with the quarantined regulations: Remove all leaves and stems/plant debris using a field cleaning machine, or apply a University of California integrated pest management-recommended material within 14 days prior to harvest.

There are no restrictions on moving fruit with leaves and stems if shipping to a packinghouse or processing facility located within the same quarantine boundary.

Asian citrus psyllids can easily “hitchhike” on citrus plant debris, so it’s important that we all do our part to minimize the movement of plant material between work sites. It is strongly recommended that growers and packers work with farm labor contractors, picking crews, pesticide applicators and hedging/topping services to ensure that all equipment, picking bags, field bins, clothing and gloves are free of stems and leaves before leaving the field.

We all have a commonality in agriculture and can understand the pressures posed by invasive insects and diseases. This is a fight that no commodity can win without the support of homeowners and consumers, which is why everyone with a backyard citrus tree should:

Not move citrus—Do not move citrus plants, plant material or fruit into or out of a quarantine area or across state or international borders.
Inspect your trees—Inspect your citrus trees for signs of the psyllid or HLB whenever watering, spraying, pruning or otherwise tending to trees.
Plant responsibly—Plant trees from reputable, licensed California nurseries.
Talk to your local nursery—Ask about products that are available to help stop the Asian citrus psyllid.
Graft with care—Use only registered budwood that comes with source documentation.
Be mindful of clippings—Dry or double-bag plant clippings prior to disposal.
Cooperate—Cooperate with agricultural officials who are trapping and treating for the Asian citrus psyllid.

By working together, we can help stop the Asian citrus psyllid and protect California citrus from Huanglongbing.
