Trump Election May Help California Agriculture

President-Elect Trump May Help Make California Agriculture Great Again!

By Patrick Cavanaugh, Farm News Director

The election of Donald J. Trump as the 45th President of the United States may prove very significant for California. He and his future administration may be able to make sense of the devastating water deliveries diverted from California farms to protect fish species that may already have become extinct, in order to comply with the Endangered Species Act.

Joel Nelsen, president, California Citrus Mutual and a leader in California agriculture, is encouraged by the election results. “You know, the Donald Trump election was a bit of a surprise to me. You can always hope, but the numbers did not look that good. Now that he is our president-elect, I think we can be somewhat optimistic about the next Congress and this next administration,” Nelsen said.

Nelsen said the optimism is going to be on several fronts. “One, I think we have an opportunity now to move water legislation that contains real storage and creates water for a bigger population in California,” he said.

“We also have an opportunity to slow down a rogue agency—which I would call Environmental Protection Agency (EPA)—and their activity specific to crop protection tools. We can get an effort going to modernize the Endangered Species Act. Nobody wants to eliminate species, but let’s face it, when that was first signed and passed, it was two generations ago. I think we need to take another look at that,” he said.

Nelsen noted there are some opportunities on the horizon. He hopes the upcoming Congress and new presidential administration will generate some positive activity for the California agriculture industry .

Nelsen and other California ag leaders will soon return to Washington to make sure things are getting done. “A couple of us are going back next week for the lame-duck session because we are hoping Congress will pass a budget that will fund the Asian Citrus Psyllid and Huanlongbing program,” he said. “There is no money for it in the USDA budget. As a result, the support at the federal level is less than what it could be or should be.”

“Because the current administration is going to be in office until January 19, 2017, the activists have until then to get things moving in a direction that cannot be stopped from their perspective. I don’t think these next two months will necessarily be quiet.”

“We must have a mindset that others will attempt to do what they think cannot be done. It will be up to many of us in leadership positions to ensure that there’s still a balanced approach with this administration before the next one comes in,” Nelsen said.

BREAKING NEWS: ACP QUARANTINES IN MERCED AND MONTEREY COUNTIES

ASIAN CITRUS PSYLLID (ACP) QUARANTINES IN MERCED AND MONTEREY COUNTIES

Quarantines are now in place in both Merced and Monterey Counties due to recent Asian citrus psyllid (ACP) detections.  One ACP was detected near the City of Merced in Merced County and two ACP in one trap within the City of Salinas in Monterey County.

The quarantine zone in Merced County measures 123 square miles, bordered on the north by Kenney Avenue; on the south by W Dickenson Ferry Road; on the west by Shaffer Road; and on the east by

E Yosemite Avenue. Monterey County’s quarantine measures 111 square miles and is bordered on the north by Pesante Road; on the south by the Salinas River; on the west by Castroville Road; and on the east by Gabilan Creek. The quarantine maps for both Merced and Monterey Counties are available online at: www.cdfa.ca.gov/go/acp-maps. Please check this link for future quarantine expansions in these counties, should they occur. Quarantines in new counties will be announced separately.

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, Kings, Madera, Merced, Monterey, 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 for HLB and once a 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 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 (Merced County (209) 385-7431; Monterey County (831) 759-7325).  For more information on the ACP and HLB, please visit: www.cdfa.ca.gov/go/acp.

Patience: How Homeowners Can Help ACP Detection

Authorities Need to Monitor ACP Detection, Confronted With Impatient Homeowners

by Patrick Cavanaugh, Farm Director

44111-CCM-Web_Headshot_Joel-Nelsen
Joel Nelsen, President of California Citrus Mutual

Joel Nelsen, the president of the Exeter-based California Citrus Mutual noted that most homeowners do not realize how intensive it is for authorities to monitor traps for the Asian Citrus psyllid (ACP) at their homes.

“Most people don’t realize how intrusive this process is,” said Nelsen. “You’ve got a member of the County Ag Commissioner’s office driving down a street. He sees a citrus tree in a front yard, or he can see it’s tall enough in the back. He knocks on the door. The homeowner’s not home, so he has to come back.”

“Later, he comes back to the home and again, knocks on the door and finds that the homeowner is home. He says, ‘Can I put a trap out here to find out if you’ve got the Asian citrus psyllid?’ The homeowner hopefully says, ‘Yes.’ He comes back in two weeks. He looks at the trap. There’s no ACP. He comes back two weeks later, and if the homeowner is home, he looks at the trap,” Nelsen explained.

“It’s a constant bother to that homeowner,” Nelsen said. “Eventually, they find more than one ACP. Then the inspector says: ‘Can I spray a crop protection material on your tree and kill the Asian citrus psyllid?’”

“Hopefully the homeowner says, ‘Yes,’” said Nelsen.

CCMLogoNelsen noted that the inspector visited five times already within a two month period, and now he needs to do inspect elsewhere, so having that homeowner be amenable to that much intrusiveness is a significant goal.

Nelsen noted, “The consumer education program that forms the partnership between us and them, from our perspective, is vitally important so the consumers understand what Huanglongbing (HLB)—the fatal citrus disease carried by ACP—is”.

“Then when you find Huanglongbing (HLB),” said Nelsen, “and hopefully it’s very minimal, that homeowner is more likely to agree that the tree must be removed. Fortunately, everybody has said: ‘Yes.’”

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.

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. All citrus and closely related species, such as curry trees, are susceptible hosts for both the insect and 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 .

NEW TULARE COUNTY ASIAN CITRUS PSYLLID DETECTIONS NEAR EXETER  

BREAKING NEWS 

 

The Tulare County Agricultural Commissioner’s office announced TODAY that one additional Asian Citrus Psyllid (ACP) has been detected on a trap south of the city of Exeter. The latest interception was confirmed by the California Department of Agriculture (CDFA). Maps and current information are available on the Agricultural Commissioner’s website by visiting: http://agcomm.co.tulare.ca.us/default/.

CDFA has already begun to saturate the affected area 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 Asian citrus psyllid 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 until it dies. To date, HLB has been detected on just one residential property in the Hacienda Heights neighborhood of Los Angeles.

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

Residents in the area who think they may have seen the pest are urged to call CDFA’s Pest Hotline at 1-800-491-1899 or the Tulare County Agricultural Commissioner at (559) 684-3350. Media inquiries related to technical questions about Asian Citrus Psyllid and Huanglongbing disease are encouraged to contact Katie Rowland, Account Coordinator for Nuffer, Smith, Tucker Inc. at (661) 817-3638.

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

Asian Citrus Psyllid Quarantine Expansion in Kern County

An additional portion of Kern County has been placed under quarantine for the Asian citrus psyllid (ACP) following the detection of one psyllid in a residential neighborhood south of the City of Bakersfield in Kern County.

CDFA officials are going door to door to notify owners of the spray mandate.

The new Asian citrus psyllid quarantine zone measures 113 square miles in and around the City of Bakersfield, bordered on the north by New Stine Road; on the east by S Fairfax Road; on the south by Millux Road; and on the west by Interstate 5.  This area is in addition to the previously announced quarantine areas in Kern County.  A map is available online at:  www.cdfa.ca.gov/plant/go/acp-quarantine.

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.

Asian Citrus Psyllid Quarantine Expansion in Tulare County

An additional portion of Tulare County has been placed under quarantine for the Asian citrus psyllid (ACP) following the detection of two psyllids in separate traps in an unincorporated area northwest of the community of Ivanhoe in Tulare County. This brings the total quarantine area in Tulare County to 856 square miles.

The new quarantine zone measures 110 square miles in Tulare County, bordered on the north by Avenue 384; on the east by Road 180; on the south by E Main Street; and on the west by Road 80.

The new quarantine zone will connect existing quarantine zones already in place. A map is available online at: http://pi.cdfa.ca.gov/pqm/manual/pdf/maps/3435ACPTulareCounty.pdf

Also, a single ACP has been detected west of Exeter near the community of Farmersville recently and may lead to another quarantine expansion later this month. The parameters and size of that additional new regulated area are still being determined.

In addition to the developments in Tulare County, ACP quarantines remain in place in Fresno, Kern, Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, San Luis Obispo, 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 pest 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.

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 HLB, please visit: www.cdfa.ca.gov/go/acp.
