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.

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.

HLB has been detected just once in California – in 2012 on a single residential property in Hacienda Heights, Los Angeles County. HLB 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, and the two have been detected in all 30 citrus-producing counties in that state. The University of Florida estimates the disease has tallied more than 6,600 lost jobs, $1.3 billion in lost revenue to growers and $3.6 billion in lost economic activity. The disease is present in Georgia, Louisiana, South Carolina, and Texas. The states of Alabama, Arizona, Hawaii, and Mississippi have detected the pest but not the disease.

Residents in the area who think they may have seen the Asian citrus psyllid are urged to call CDFA’s Pest Hotline at 1-800-491-1899. For more information on the Asian citrus psyllid and huanglongbing disease, please visit: www.cdfa.ca.gov/go/acp

Ag Official on Asian Citrus Psyllid in Tulare County

Marilyn Kinoshita, Tulare County Ag Commissioner, talks about the Asian Citrus Psyllid and how its affecting growers in the area.

“Our growers have the heavy commercial production as opposed to the ranchettes in San Diego Count, so we got more emphasis on spray treatments immediately after a find. We’ve had really good success rate, and so our trapping program is top-notch, so if psyllids are found, we have the ability to eradicate immediately and keep it under control that way,” said Kinoshita.

The Asian Citrus Psyllid, or ACP, is a tiny insect that acts as a carrier of the citrus disease Huanglongbing, also known as citrus greening disease. this bacterial disease is transmitted by the ACP, after it feeds on affected plant tissue.

Without proactive measures such as quarantine and eradication treatments, ACP could have dire consequences for the entire California citrus industry.

“We always knew that we were going to be ground zero. Because we’ve got the most packing sheds in the state, and the most juice facilities, and we’re receiving products from Mexico, Texas, Arizona, and Southern California and our growers need to stay diligent. We got all but 13,000 acres of citrus within the quarantine area, and so that can cause some problems with not having the entire county included,” said Kinoshita.

Citrus Greening Disease has only recently become a problem for California. The first infected plant was discovered in March 2012. It has still caused a concern in that short period of time, as the California Department of Food and Agriculture has found that here is no physical, cultural, or biological methods to completely eradicate ACP.

“So far we are dealing with it, and I have heard that this fall would kind of be the ‘trigger point’ that the Southern California counties saw at the two and a half year point of having Psyllids in their county. So we will see,” said Kinoshita.

UPDATE: ACP Quarantine and Advocacy for Unimpeded Eradication

by Laurie Greene, Editor

CDFA filed a proposed emergency amendment TODAY to expand the ACP quarantine area in response to an “infestation” of the Asian citrus psyllid (ACP), Diaphorina citri, detected in the Farmersville/Visalia area (June 4, 2014), Tulare County. One adult female was found in the area. The proposed 14-mile expansion will include the Visalia area, and the state’s vast ACP quarantine will cover 46,544 sq. miles.

CDFA Secretary Karen Ross

The regulation defines emergency as” a situation that calls for immediate action to avoid serious harm to the public peace, health, safety, or general welfare.” The government code provides,”if the emergency situation clearly poses such an immediate, serious harm that delaying action to allow public comment would be inconsistent with the public interest, an agency is not required to provide notice.”

CDFA Secretary Karen Ross believes that this emergency clearly poses such an immediate, serious harm that delaying action to give the notice would be inconsistent with the public interest. Therefore, Ross proposed that the CDFA Director may adopt reasonably necessary measures such as bypassing the mandatory notice five working days prior to emergency action in order to carry out emergency provisions. Additionally, she requested that the Director be permitted to establish, maintain, and enforce quarantine, eradication, and such other regulations necessary to circumscribe and exterminate or prevent the spread of any pest which is described in the code.

This comes after the California Citrus Industry’s recent backlash against the Executive Committee of the California Citrus Pest and Disease Prevention Committee’s proposed easing of the state’s ACP quarantine and eradication efforts.

Joel Nelsen, CA Citrus Mutual President

And, while CDFA uses the word, “infestation”, Joel Nelsen, President of California Citrus Mutual, commented at the recent United Fresh Convention in Chicago, “There were two more ACP finds found in the northeast part of Tulare County. They were individual finds. Intensive trapping and tapping on the trees, looking for the ACP, hasn’t found any more. So one would argue that we’ve got a population—given the finds in the last year—but we’re still talking single digits.” Nelsen believes this demonstrates the eradication programs are working. “We’re supposed to find the ACP before finds a commercial citrus industry, and we’re doing that.”

Nelsen said the Executive Committee’s recent proposal to significantly modify the program was, “based upon some subjective analysis by a team of scientists who in fact believe that there’s more out there than what we can find.”

“So,” he continued, “we’re obligated to prove a negative; and as long as we do the intensive trapping program, as long as we continue the mandated treatment program, as long as we’re aggressively looking for the Asian citrus psyllid—I don’t see how, and industry doesn’t buy into the fact, you have an endemic population. We’re not finding them in volume; everything is isolated.”

“So, when the industry first became aware of this possible change in the treatment zones of the quarantine mandates, the industry challenged CDFA.”

Now, not only does the ACP program remain intact, but TODAY, CDFA Secretary Ross proposed measures for an unhindered and immediate eradication response by CDFA to ACP discoveries.

Ventura County ACP Report Less Than Uplifting

Joanne O’Sullivan, a licensed PCA and QAL (Qualified Applicator), and a Citrus Pest & Disease Prevention Program Grower Liaison in Ventura County, reported TODAY that four new urban settings with 25 or more citrus trees on the property have been discovered in Asian citrus psyllid treatment areas in recent weeks. These four finds are within the same area as the commercial Camarillo find in March.

CDFA deems these orchards also as commercial; therefore, the homeowners are financially responsible for the treatment.

O’Sullivan said, “The first two homeowners I contacted were more than willing to cooperate and take on the financial costs of spraying. They understand it is necessary for the benefit of both their trees and the health of Ventura County’s citrus industry. The third homeowner opted to remove 15 of his trees and CDFA then sprayed the remaining ten. The last and remaining homeowner will take a bit more convincing, but I am confident they will come to see the great benefits of working with us.”

“On a less uplifting note,” O’Sullivan continued, “it has been an unlucky month for Fillmore and Piru producers. Piru has been hit again in the Bardsdale area with two ACP confirmations in the same week. These same growers had completed the ACP psyllid spray protocol in November of last year. It goes without saying that the producers are less than delighted to be repeating treatment again so soon.”

She reiterated a very important element in the ACP/HLB program, ”The goal of the [Ventura County ACP-HLB] Task Force has been to delay as long as possible the introduction of HLB into Ventura County. As a result of the progressive and aggressive work from producers, packers, pest advisors, operators and the CDFA and county trapping programs, Ventura remains one of the most successful ACP/HLB programs in the state.

A critical element of ACP treatment protocol for organic growers is the importance of scouting post-treatment. All blocks must be aggressively monitored following applications, using the sampling protocol that is included in the ACP CONFIRMATION IN YOUR AREA packet.

Current protocol requires organic producers to sample every two weeks after the third treatment. Sampling every two weeks allows the grower to document control. Early detection and swift eradication is our best defensive against the introduction of HLB and its devastating effects on Ventura citrus producers.

Every producer – commercial and organic – should be familiar with the signs of Asian citrus psyllid. Literature on identifying ACP is available at the CRB, UCIPM, UC Cooperative Extension as well as from CDFA. Share it with your workers. If you have any doubts about your ability to identify adults, nymphs, and eggs, please contact me, I am always glad to meet with you on your ranch and help you scout.

In closing, I was forwarded an interesting short news article outlining the economic hit Florida has taken as the result of HLB, with annual production dropping from 1,000,000 boxes of fruit to 750,000. This news story is a not- so-gentle reminder of why it is vitally important that everyone working together in a cooperative spirit can keep Florida’s scenario from happening in California.

Take a look:

Asian Citrus Psyllid Quarantine Established in San Luis Obispo County

Breaking News: NEW ACP Discovery

Victoria Hornbaker, APHIS Citrus Program Manager, announced TODAY the first confirmed Asian citrus psyllid find in San Luis Obispo County as reported in a San Luis Obispo County Ag Commissioner’s press release.

Hornbaker also announced a Science Advisory Panel Report Stakeholder meeting will be held on April 16, 2014 at 9 am at CDFA headquarters, 1220 N Street, Room 220, Sacramento, CA 95814. To participate via conference call, please call 866-692-3158 and use participant code 87947483.

The meeting agenda follows this article.

Martin Settevendemie, Agricultural Commissioner/Sealer, County of San Luis Obispo announced detection of an adult Asian Citrus Psyllid in an insect trap on March 26^th in a residential landscape near Arroyo Grande. The discovery prompted a high-density trapping delimitation survey of the immediate and adjacent area – about a nine square mile area – and no other ACPs were found.

A quarantine restricting the movement of citrus nursery stock and citrus fruit within a five-mile radius around the detection site has already been established by the California Department of Food and Agriculture to prevent the spread of this serious plant pest. “We are working with growers to get everyone in compliance with the regulation. This will help them understand what the requirements are to move any product outside of the quarantine area,” said Settevendemie.

CDFA announced that they will be conducting spray eradication treatments approximately 800 meters around the detection to eradicate this pest.

The first detection of the Asian Citrus Psyllid in California occurred in San Diego County in 2008. Since then, it has been found throughout southern California.

“This insect pest is of serious concern to California’s commercial citrus because it is responsible for spreading Huanglongbing, also called citrus greening disease, a plant disease that is fatal to all types of citrus trees. This includes citrus trees in countless landscapes across the county as well as local commercial citrus orchards valued at over $13 million in 2013,” according to Settevendemie.

Over the past ten years nearly 50% of the commercial citrus groves in Florida have been killed by this disease. The University of Florida estimates the disease has tallied more than 6,600 lost jobs, $1.3 billion in lost revenue to growers and $3.6 billion in lost economic activity for the state. The disease does not affect human health.

A single orange tree infected with Huanglongbing was found in a Los Angeles County backyard in 2012. To date no additional detections of the disease in California have occurred.

Staff from the San Luis Obispo County Agricultural Commissioner’s office and officials from the California Department of Food and Agriculture continue to search for this pest by monitoring hundreds of insect traps placed in urban neighborhoods and commercial orchards throughout the county.

“It is difficult to close off all potential pest pathways into the county. An engaged community of all county residents is critical in successfully excluding pests such as Asian Citrus Psyllid,” said Settevendemie.

Community members can do the following to protect backyard citrus trees and the local citrus industry:

        Buy Local! Purchase citrus trees from reputable local sources selling plants that have been routinely inspected by the Agricultural Commissioner’s staff.
        Do not transport citrus plants or plant parts into the county from quarantine areas. Call 805- 781-5910 for information about quarantine areas.
        Check residential landscaping often for signs of unusual symptoms or strange insects. Contact the local University of California Cooperative Extension’s Master Gardener Program at 805-781-5939 for help in identification of unusual plant symptoms or pests.
        If asked, allow the Agricultural Commissioner’s staff to place an insect trap in your yard and cooperate with officials if it becomes necessary to exclude or eliminate Asian Citrus Psyllid from San Luis Obispo County.
