Protecting California Citrus from ACP

By Charmayne Hefley, Associate Editor

[embedvideo id=”ZWgOOjpxwE8″ website=”youtube”]

California’s $2.2 billion fresh citrus industry that supplies 85 percent of the nation’s fresh citrus is currently healthy and vibrant despite the background threat of the Asian Citrus Psyllid (ACP), according to Kevin Severns, a citrus grower in Sanger, CA; general manager of the Orange Cove-Sanger Citrus Association, a cooperative citrus packing house in eastern Fresno County; and chairman of California Citrus Mutual.

“We’re quite concerned about it,” Severns said about the ACP—a tiny bug that is a known carrier or vector of “huanglongbing” (HLB), a devastating, incurable disease of citrus trees that has already demolished the citrus industry in Florida. “We’ve been able to keep the bug at bay to this point,” Severins continued, “at least here in the Central Valley, but we’re very concerned about it. There are a lot of issues to be concerned about with this bug.”

California has taken note of the devastation of Florida’s industry, Severns said, and is taking steps to ensure the safety of California’s citrus. “Having gone to Florida with many of our citrus growers,” Severns explained, “I heard Florida growers tell we must control the bug. So we’re trying to keep this bug at bay and not allow [the infestation] to expand. We’ve had varied success in different areas of California, but so far, we’ve been able to keep the bug’s expansion here in the Central Valley to a minimum. We continue to have finds from time to time, but we haven’t yet had an explosion of the population of the ACP.”

Severns said, “We have a very successful partnership with the California Department of Food and Agriculture (CDFA).” While trapping ACP is critical, he emphasized the importance of enlisting the help of residential folks with citrus in their backyards to get involved in the conversation, to look for this pest, and to join in the fight. “The trap is very limited in its ability to pick up ACP, so it’s very important that we have visual surveys in which growers and homeowners actually go out and look at their trees for the bug.”

Severns said current measures against the spread of the ACP is helping to buy time for researchers to find a cure for HLB. “We realize every place on earth where the ACP has gone, eventually has been followed by HLB,” Severns said, “so we’re trying very hard to buy time and give our researchers and scientists a chance to come up with a solution to this disease—whether it is a resistant type of citrus variety or a cure for the trees.”

Preventing the spread of ACP and HLB, from commercial citrus growers to residential citrus growers, will require that everyone works together. To learn more, go to CaliforniaCitrusThreat.org or contact your local Ag Commissioner.

UPDATE! Expanded ACP Quarantine

UPDATE! Expanded ACP Quarantine in Stanislaus and Merced Counties

Two ACPs Found in City of Turlock

Stanislaus County has been placed under quarantine for the Asian citrus psyllid (ACP) following the detection of two ACPs within the City of Turlock. The expanded ACP quarantine also includes a portion of northern Merced County along its border with Stanislaus County. The quarantine zone measures 101 square miles, bordered on the north by East Service Road; on the south by August Avenue; on the west by Blaker Road; and on the east by North Hickman Road. The quarantine map for Stanislaus and Merced is available online at: www.cdfa.ca.gov/go/acp-maps.

The quarantine prohibits the movement of citrus and curry leaf tree nursery stock, including all plant parts except fruit, 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 which are designed to keep ACP and other insects out. 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.

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 Alameda, Fresno, Kern, Madera, Merced, San Benito, San Francisco, San Joaquin, San Luis Obispo, San Mateo, Santa Clara, and Stanislaus 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. All citrus and closely related species, such as curry leaf trees, are susceptible hosts for both the insect and disease. There is no cure once the tree becomes infected; the diseased tree will decline in health and produce bitter, misshaped fruit until it dies. In California, HLB has only been detected in 2012 and 2015 on residential properties in 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 trees are urged to call CDFA’s Pest Hotline at 1-800-491-1899 or your local agricultural commissioner’s office (Stanislaus County (209) 525-4730; Merced County (209) 385-7431). For more information on the ACP and HLB, please visit: www.cdfa.ca.gov/go/acp.

#CitrusMatters Spreads Info

#CitrusMatters Helps Spread Word on Serious Citrus Greening Disease

By Kyle Buchoff, Assistant Editor

Steve Olson, senior product manager for Bayer CropScience has a big passion for citrus, an important U.S. crop currently at risk to Huanglongbing (HLB), also known as citrus greening, a bacterial citrus plant disease. The vector of the deadly disease is a tiny insect known as the Asian citrus psyllid. Bayer CropScience launched the #CitrusMatters initiative this year to fully convey the significance of HLB to the California public.

Olson said the initiative focused on California’s urban settings because more than 60 percent of homeowners in California grow citrus trees in their yards. “We felt we could have some influence on broadening public awareness of this very significant disease.”

“So we introduced the #CitrusMatters initiative with California Citrus Mutual to help spread through social media the importance of citrus and how people enjoy citrus,” said Olson. “We were trying to make that emotional connection, and I think to a degree we have had some success. We held a #CitrusMatters Day in San Diego on May 8 and in Los Angeles on July 2, and tried to engage mass media. I think it is a very important undertaking to really bring awareness to homeowners who have citrus in their backyards.”

Fighting ACP in California

Fighting ACP In California to Stay Well Ahead of HLB

By Patrick Cavanaugh, Deputy Editor

With more than 275,000 acres of citrus trees in California, keeping the Asian Citrus Psyllid (ACP) out of groves is a serious concern. Bob Blakely, vice president of California Citrus Mutual, based in Exeter, talked to California Ag Today about how growers are fighting ACP in California.

“We’ve been very proactive, ever since the first psyllid was found here back in 2008. We already had an action plan in place when that psyllid was found. We have engaged with and educated the public and the media, and we have very good cooperation with the state’s citizens,” Blakely said.

Blakely noted the industry is using a variety of methods, “We are usually able to go in and treat urban areas in Southern California, where ACP is now endemic, with crop protection materials. If we determine we cannot control it with pesticides, we implement a new biological program by releasing the parasitoid Tamarixia (a tiny non-native wasp) in residential areas. The new wasp is becoming well-established, and we are hoping the species will help manage ACP populations.”

“We hope to prevent ACP from creating the type of damage seen in Florida, where the citrus industry has been reduced by 50%,” said Blakely. “We are way ahead of the game here in California. We have managed to slow ACP spread in commercial areas in order stay ahead of the spread of the HLB disease the bug carries. We hope a reasonable cure can be found so we can prevent the kind of devastation we are witnessing in some other states.”

ACP Devastates Florida Citrus

ACP Devastates Florida Citrus Industry; California Continues Vigilance

By Patrick Cavanaugh, Deputy Editor

California Citrus growers must not underestimate the potential damage from Asian Citrus Psyllid (ACP), according to Bob Blakely, vice president, California Citrus Mutual, based in Exeter.

Given multiple ACP detections in California this year, Blakely used Florida’s ACP catastrophe as an example of how devastating the pests can be. “We are challenged here in California with ACP,” Blakely began, “which vectors the fatal disease known Honglongbing, (HLB), also known as citrus greening. But, it is nothing like what they are dealing with in Florida, since HLB [the disease itself] was discovered there less than ten years ago. “Florida’s citrus acreage, which measured just under 1 million acres prior to the calamities they’ve been facing,” said Blakely, “has been reduced by almost 50%.”

Bob Blakely, VP, California Citrus Mutual

While occurrences of Citrus Canker Disease as well as urbanization also contributed to the reduction in acreage, Blakely stated, “the big killer, citrus greening, is mostly responsible for the reduction of citrus acreage to the lowest level in decades.”

Because Florida has become so infested with ACP and HLB, reestablishing the industry there will take some time. “They are replanting and trying to replant healthy trees,” Blakely explained, “but they know those trees are short-lived compared to trees in California. We have hundred year-old groves. Florida farmers are just hoping to raise those trees and get a few years of production out of them before HLB re-infects them and they must be replaced again,” said Blakely.

Citrus Growers Determined to Succeed

Frustrated Citrus Growers Are Determined to Succeed

By Patrick Cavanaugh, Deputy Editor

While farmers have been dealing with some tough times, Bob Blakely, vice president of California Citrus Mutual is optimistic about future generations of citrus growers, “Perceptions and attitudes are really all over the board; we’ve got growers who are really frustrated and ready to throw it in. But most growers are staying in, thinking they can still make it in the citrus industry.”

“California growers are known for their tenacity in the face of challenges,” Blakely commented. “It’s exciting to see young farmers come on, even though they continue to fight the regulatory battles and higher farming costs. But these young guys have the same determination the prior generation had when they started. So, I am optimistic about the future of the citrus industry in California.”

One of the major threats to citrus is the Asian Citrus Psyllid (ACP) and its potential to spread the disease Huanglongbing (HLB), as it has in Florida and Texas. “We are very concerned about the recent HLB finds. Here again, they have been discovered in residential areas, which is no surprise to us. That is typically where diseases first show up. At the present time, the ACP are contained. We are starting to delimit that area, and residents are very cooperative in allowing those trees to be removed.”

URGENT HLB Quarantine UPDATE

HLB Quarantine Update

A Huanglongbing (HLB) quarantine is now in effect in part of Los Angeles County following the detection of HLB in four citrus trees.

On July 10, a kumquat tree on a residential property was confirmed to be infected with the incurable HLB disease. After extensive surveying and testing in the area, three more diseased trees were found nearby. The four diseased trees were on four separate properties close to one another. The tree varieties include kumquat, lime, mandarin and calamondin.

California Department of Food and Agriculture (CDFA) has already removed two of the diseased trees and is currently working with the homeowners at the other two properties to remove those trees as soon as possible. See the CDFA press release below for more details on the resulting quarantine.

QUARANTINE FOR HUANGLONGBING DECLARED IN SAN GABRIEL, LOS ANGELES COUNTY

SACRAMENTO, July 22, 2015 – An 87-square mile quarantine in the San Gabriel area of Los Angeles County has been added to the existing huanglongbing (HLB) quarantine in the Hacienda Heights-area following the detection of the citrus disease huanglongbing, or citrus greening.

Additional information, including a map of the quarantine zone, is available at the CDFA Save Our Citrus website. The quarantine boundaries are: on the north, E. Orange Grove Boulevard; on the east, N. Lemon Avenue; on the west, Griffin Avenue; and on the south W. La Habra Boulevard.

This area is part of a much larger quarantine already in place for the Asian citrus psyllid (ACP), the pest that spreads bacteria causing huanglongbing (HLB). The new quarantine will prohibit the movement of all nursery stock out of the area, while maintaining existing provisions allowing the movement of only commercially cleaned and packed citrus fruit. Any fruit that is not commercially cleaned and packed, including residential citrus, must not be removed from the property on which it is grown, although it may be processed and/or consumed on the premises.

“The success of any quarantine depends on cooperation from those affected,” said CDFA Secretary Karen Ross. “The stakes couldn’t be higher for California citrus. We urge residents in the San Gabriel-area to do all they can to comply.”

CDFA, the USDA and the Los Angeles County Agricultural Commissioner’s continue their work to investigate the source of the disease, to survey and test for it throughout the Los Angeles Basin, and to continue with ground treatment of citrus trees within 800 meters of the find sites – which began earlier this week. In the long term, the strategy is to control the spread of ACPs while researchers work to find a cure for the disease.

Huanglongbing has been confirmed four times in San Gabriel, in a kumquat tree on a residential property, in a lime tree on an adjacent residential property, and in calamondin and mandarin trees on residential properties in close proximity to the original find. The disease is bacterial and attacks the vascular system of plants. It does not pose a threat to humans or animals. The Asian citrus psyllid can spread the bacteria as the pest feeds on citrus trees and other related plants. Once a tree is infected, there is no cure; it typically declines and dies within a few years.

Huanglongbing is known to be present in Mexico and in parts of the southern U.S. Florida first detected the disease in 2005, and the University of Florida estimates that the disease causes an average loss of 7,513 jobs per year, and has cost growers $2.994 billion in lost revenue since then. Huanglongbing has also been detected in Georgia, Louisiana, South Carolina and Texas as well as Puerto Rico and the U.S. Virgin Islands.

A total of 15 states or territories are under full or partial quarantine due to the presence of the ACP: Alabama, American Samoa, Arizona, California, Florida, Georgia, Guam, Hawaii, Louisiana, Mississippi, Northern Mariana Islands, Puerto Rico, South Carolina, Texas, and the U.S. Virgin Islands.

The Asian citrus psyllid was first detected in California in 2008 and quarantines for the pest are now in place in 17 California counties. If Californians believe they have seen evidence of huanglongbing in local citrus trees, they are asked to please call CDFA’s toll-free pest hotline at 1-800-491-1899 FREE.

HLB Found in LA

Huanglongbing Detected on LA County Pre-Symptomatic Kumquat Tree

By Patrick Cavanaugh, Farm Director; Laurie Greene, Editor, California Ag Today

#CitrusMatters (provided by Bayer CropScience, in partnership with California Citrus Mutual)

“It’s disappointing, but fortunately it was found in a residential area,” commented Joel Nelsen, president of California Citrus Mutual (CCM), on the second discovery of Huanglongbing [wong-long-bing] (HLB), or citrus greening, in California. CCM refers to HLB as “a death sentence for California citrus” as once the plant is infected with this bacterial disease, there is no known cure.

Joel Nelsen, president, California Citrus Mutual

“HLB was detected in plant material taken from a kumquat tree in a residential neighborhood in the San Gabriel area of Los Angeles County,” Nelson stated. “The 20-year-old tree was in the front yard of a residence and had not yet shown any symptoms.”

The San Gabriel neighborhood is located about 15 miles from Hacienda Heights, where the first HLB case in the state was detected in 2012 in a residential citrus tree. The An aggressive trapping program for the Asian citrus psyllid (ACP), a pest known to spread the HLB bacteria as it feeds on citrus trees and other plants, has been ongoing ever since this first finding, including in the San Gabriel area.

“It’s fortunate that the homeowner is quite cooperative,” said Nelsen, “and other neighborhood homeowners are allowing officials to run PCR tests (polymerase chain reaction) on samples of their trees to determine if the disease is present.” PCR analysis is a sensitive research technique for detecting and identifying small numbers of bacteria in plants via DNA amplification.

Nelsen declared, “This find is exactly what the Citrus Pest and Disease Prevention Program is designed to do. PCR testing of a random sampling of leaves and stems in the area, as our program prescribes, enabled us to hit a positive” before symptoms appeared.

“We do not know how long the tree had been diseased,” said Nelsen, “but we do know that we have been trapping ACPs there for a long time and had not found any HLB before. You do not want to

find anything,” Nelsen said, “but when you do, you want to find it before it becomes an epidemic.”

In a statement on Friday, California Department of Food and Agriculture (CDFA) Secretary Karen Ross said, “Citrus is a cherished part of our landscape and our shared history, as well as a major agricultural crop.” CDFA has been planning and preparing for HLB detections since before the first ACP was detected in the state in 2008. Quarantines are now in place in 17 California counties.

Los Angeles County Agricultural Commissioner Kurt Floren will mobilize his team over this week to check on citrus trees in plant nurseries that fall within the 800-meter radius around the infected tree area. A spray protocol is already in place for all citrus trees within the 800-meter radius.

“More traps are going out so we can try to delineate the scope of the problem. Hopefully it will be nothing more than this one tree, like the solitary diseased tree we found in Hacienda Heights,” Nelsen said.

BREAKING NEWS ON HUANGLONGBING CITRUS DISEASE

HUANGLONGBING CITRUS DISEASE DETECTED IN SAN GABRIEL AREA OF LOS ANGELES COUNTY
CDFA
Release #15-031

Sacramento, July 10, 2015 – The California Department of Food and Agriculture (CDFA) and the United States Department of Agriculture (USDA) have confirmed detection of huanglongbing (HLB) citrus disease, or citrus greening. The disease was detected in plant material taken from a kumquat tree in a residential neighborhood in the San Gabriel area of Los Angeles County.

This is the second time HLB has been detected in California. The first detection occurred in 2012 in a residential citrus tree in Hacienda Heights, about 15 miles from San Gabriel.

HLB is a bacterial disease that attacks the vascular system of plants. It does not pose a threat to humans or animals. The Asian citrus psyllid (ACP) can spread the bacteria as the pest feeds on citrus trees and other plants. Once a tree is infected, there is no cure; it typically declines and dies within a few years.

“Citrus is a cherished part of our landscape and our shared history, as well as a major agricultural crop,” said CDFA Secretary Karen Ross. “CDFA is moving quickly to protect the state’s citrus. We have been planning and preparing for HLB detections with our growers and our colleagues at the federal and local levels since before the ACP was first detected here in 2008.”

A CDFA crew has removed and disposed of the infected tree and is preparing to conduct treatment of citrus trees for ACP infestation within 800 meters of the find site. By taking these steps, a critical reservoir of disease and its vectors will be removed, which is essential.

An intensive survey of local citrus trees and psyllids is underway to determine if HLB exists anywhere else in the area. Planning has begun for a quarantine of the area to limit the spread of the disease by restricting the movement of citrus trees, citrus plant parts, green waste, and all citrus fruit except what is commercially cleaned and packed. As part of the

SAVE OUR CITRUS app is a free USDA iPhone to report and identify the four leading citrus diseases: citrus greening, citrus canker, citrus black spot and sweet orange scab. Report your symptoms, upload a photo and citrus experts will respond.

quarantine, citrus and closely related plants at nurseries in the area will be placed on hold.

Residents of quarantine areas are urged not to remove or share citrus fruit, trees, clippings/grafts or related plant material. Citrus fruit may be harvested and consumed on-site.

CDFA, in partnership with the USDA, local agricultural commissioners and the citrus industry, continues to pursue a strategy of controlling the spread of ACPs while researchers work to find a cure for the disease.

HLB is known to be present in Mexico and in parts of the southern U.S. Florida first detected the pest in 1998, and the disease in 2005, and the two have now been detected in all 30 citrus-producing counties in that state. The University of Florida estimates that the disease causes an average loss of 7,513 jobs per year, and has cost growers $2.994 billion in lost revenue since HLB was first detected in that state in 2006.

HLB has also been detected in Georgia, Louisiana, South Carolina and Texas, as well as Puerto Rico and the U.S. Virgin Islands. A total of 15 states or territories are under full or partial quarantine due to the detected presence of the Asian citrus psyllid: Alabama, American Samoa, Arizona, California, Florida, Georgia, Guam, Hawaii, Louisiana, Mississippi, Northern Mariana Islands, Puerto Rico, South Carolina, Texas, and the U.S. Virgin Islands.

The ACP was first detected in California in 2008, and quarantines are now in place in 17 California counties. If Californians have questions about the ACP or HLB, they may call CDFA’s toll-free pest hotline at 1-800-491-1899 or visit: http://www.cdfa.ca.gov/phpps/acp/.

LA Declares Citrus Matters TODAY

LA Citizens And Commercial Citrus Growers Highlight Deadly Citrus Disease And Why Citrus Matters

LOS ANGELES (July 2, 2015) – California’s citrus industry is threatened by the Asian citrus psyllid (ACP), a tiny pest that can transmit the world’s deadliest citrus disease, Huanglongbing (HLB). Currently, all of Los Angeles County is under quarantine[1] for the psyllid, which continues to spread across the state. Along with Bayer CropScience and California Citrus Mutual, City Councilmember Gil Cedillo announced TODAY, July 2 that, “Citrus Matters” to Los Angeles. During the event, commercial citrus growers from the region were recognized for their contributions to the state of California and acknowledged the devastating disease that could destroy the state’s citrus industry. The announcement also serves to highlight the role Los Angeles residents must play in protecting California’s $2.4 billion commercial citrus industry through the #CitrusMatters initiative.

To date, the psyllid has reached 15 counties throughout Southern California[2]; however, HLB has been recorded in only one tree in California[3] – a lemon/pummelo tree found on residential property in the Hacienda Heights neighborhood of Los Angeles in 2012. For every Californian who cares about citrus, that tree, which has since been removed and destroyed, serves as a warning that all citrus trees are at risk of being affected, from the trees that decorate their neighborhood to the commercial groves nearby.

The #CitrusMatters initiative from Bayer CropScience and California Citrus Mutual encourages all residents of California and Los Angeles – where there are more citrus trees on residential property than in commercial groves – to take action to help prevent the spread of the ACP. It is essential that homeowners with citrus trees on their property understand how to protect their trees and know what to do if they suspect trees are infected. If left untreated, the insects can move quickly from one tree to the next, eventually spreading to the commercial groves that cover much of Southern and Central California.There are a number of ways the Los Angeles community can get involved with the campaign to help prevent the spread of ACP and protect California citrus, including:

Spreading the word and increasing awareness about the disease, the ACP and why they love citrus, using the hashtag #CitrusMatters. Through each use of the hashtag (now through September 30), Bayer CropScience will contribute $1, up to $25,000, to advance existing and future research to find a solution to HLB in California.
Visiting CaliforniaCitrusThreat.org to access HLB and ACP resources specific to Los Angeles County.
Monitoring their trees, contacting the California Department of Food and Agriculture (CDFA) Exotic Pest Hotline at 1-800-491-1899 if they think they’ve spotted an infestation and having their trees checked.
Becoming familiar with solutions[4] available that can protect against ACP in their trees

The citrus industry has a storied history in Los Angeles. Southern California’s first orange grove[5] was planted at San Gabriel Mission in 1804, and the state’s very first commercial citrus operation[6] was established in what is now downtown Los Angeles.

“Almost all of us native Los Angelenos have some kind of memory of grabbing a lemon off of the trees in our yards growing up or stepping outside during the spring and taking in the fresh scent of orange blossoms,” said Cedillo when he presented the announcement. “The city of Los Angeles recognizes the contribution citrus adds to California’s economy and our residents’ lives.”

“The Los Angeles area has played a vital role in the industry’s history,” said Joel Nelsen, president of California Citrus Mutual. “We’re excited to see residents celebrate citrus and rally around our mission to protect it from the spread of HLB.”

The #CitrusMatters initiative is part of the ongoing effort by Bayer CropScience to provide citrus growers across the nation with solutions to help combat ACP and HLB. To learn more about the #CitrusMatters initiative and how homeowners, commercial citrus growers and citrus lovers alike can help save citrus, visit CitrusMatters.us.
