U.S. Citrus Industry Applauds House Ag Committee Chairman GT Thompson for Prioritizing Emergency Citrus Disease Funding

On behalf of the U.S. citrus industry, we extend our sincere thanks to Chairman GT Thompson and the House Agriculture Committee for including critical funding for the Emergency Citrus Disease Research and Extension Program in the budget reconciliation draft released this week.

This investment represents a vital commitment to the long-term health and competitiveness of citrus growers in Florida, Texas, California, and across the country. The Emergency Citrus Disease Research and Extension Program is essential to combating devastating diseases like HLB (citrus greening), which continue to threaten the viability of citrus production in the United States.

“As leaders of the citrus industry, we have long advocated for dedicated federal support to address citrus disease challenges through science-based solutions,” said Matt Joyner, CEO of Florida Citrus Mutual. “Chairman Thompson’s leadership reinforces that the needs of our growers are being heard.”

Dale Murden, President of Texas Citrus Mutual, added: “This is an encouraging step forward for the citrus industry. Our growers are navigating increasing biological threats and economic pressures, and investments like this make a real difference in ensuring a future for U.S.-grown citrus.”

“California’s citrus growers, like our counterparts in Florida and Texas, are facing unprecedented challenges,” said Casey Creamer, President/CEO of California Citrus Mutual. “Chairman Thompson’s inclusion of this program is a strong signal that citrus is part of the future of American agriculture.”

While this funding is an important victory, the citrus industry continues to support passage of a comprehensive, bipartisan Farm Bill that incorporates the broader set of transformational policy reforms outlined by the Specialty Crop Farm Bill Alliance – including improvements to crop insurance, mechanization investments, and fair trade policies.

Whenever Congress invests in American agriculture, specialty crops—including citrus—must be part of the equation. U.S. citrus growers produce nutritious food for American families while contending with significant cost, regulatory, and climate-related pressures. This funding is a meaningful step, but additional action is needed to ensure the long-term competitiveness and sustainability of our industry.

Update on Citrus Yellow Vein Clearing Virus

By Citrus Insider

Two new detections of citrus yellow vein clearing virus (CYVCV) have been confirmed in rural residential citrus trees in the city of Visalia in Tulare County. The detections resulted from an ongoing survey and sampling activities conducted by the California Department of Food and Agriculture (CDFA). CYVCV had previously been confirmed in the city of Tulare, also in Tulare County.

CDFA staff have been conducting survey and sampling activities of CYVCV host plants in Tulare County on residential properties throughout the area to determine the extent of the disease and potential impacts, and surveys will be ongoing for the near future. Survey results – along with CDFA’s robust pest prevention system that focuses on exclusion and monitoring, as well as CDFA and the U.S. Department of Agriculture’s (USDA) experience responding to other vectored disease threats – will be critical in developing an appropriate joint regulatory response.

CYVCV can be spread by vectors as they move from tree to tree, feeding on foliage. The vectors include citrus whitefly, green citrus aphid, melon or cotton aphid, and cowpea aphid, which are all known to be present in California. CYVCV can also be spread through the grafting and movement of infected propagative materials, rootstocks, or contaminated tools and equipment.

While there is no treatment for this disease, as of now, the best mitigation measure is to control the vector and sanitize tools and equipment. To the greatest extent possible, growers are encouraged to urge their field crews to clean and sanitize all their equipment thoroughly between jobs or when moving between groves.

For questions about CYVCV, please call the CDFA Pest Hotline at 1-800-491-1899 or contact your local Grower Liaison.

Asian Citrus Psyllid Study: Vigilance Urged but ‘No Cause for Panic’

By Mike Hsu, UCANR

Preliminary results indicate 3.5% of ACP collected showed signs of bacterium that can cause huanglongbing

An ongoing study in the commercial citrus groves of coastal Southern California is looking at whether Asian citrus psyllids – the insect vector of huanglongbing “citrus greening” disease – are carrying the bacterium that can cause HLB.

Thus far, the project has tested more than 3,000 adult ACP collected from 15 commercial citrus sites across the region, of which 138 – just over 3.5% – had some level of the bacterium present, according to researchers from UC Agriculture and Natural Resources, UC Davis, UC Riverside and the University of Arizona, Tucson.

“While the results are a cause for concern, the situation in California is much better than in Florida and Texas, where ACP carrying the bacterium make up the majority of the population and HLB is widespread in commercial citrus,” said Neil McRoberts, a UC Davis plant pathologist and UC Integrated Pest Management program affiliate advisor. “The results indicate that there is no room for complacency, but also no cause for panic.”

Since the first HLB-infected tree in California was found in 2012, nearly 4,000 infected trees have been detected and removed from residential properties in Southern California, mainly in Orange and Los Angeles counties. According to McRoberts, “to date, no HLB has been found in commercial citrus” in California.

He stressed, however, that the aforementioned ACP study – funded by the HLB Multi Agency Coordination Group and managed by USDA-APHIS – does not involve any testing of trees for HLB and focuses only on looking at the insect which spreads the bacterium.

McRoberts also emphasized that the project’s detections of the bacterium cannot be considered “official” because the researchers’ lab procedures differ from the official testing protocols of the California Department of Food and Agriculture.

“Follow-up sampling by CDFA staff would allow official samples to be collected for further investigation, but is entirely voluntary for the growers involved,” he said, adding that his research team is currently wrapping up the sampling phase of the project, with data analysis continuing into 2023.

While commending the “huge coordinated effort” by the California citrus industry, California Department of Food and Agriculture, UC ANR and other partners to suppress the ACP vector and slow the spread of HLB, McRoberts also urged continued vigilance.

“Our study results indicate that it is not time to declare the emergency status for ACP/HLB in California over – the situation is still evolving,” he said.

Notice of the 2022-2023 Assessment Rate for the California Citrus Research Program

Upon the recommendation of the Citrus Research Board (Board), the California Department of
Food and Agriculture (Department) has established an assessment rate to be levied on California
citrus producers during the 2022-2023 marketing season, which is the period of October 1, 2022
through September 30, 2023. The assessment rate for the 2022-2023 marketing season has been
set at three and two-tenths cents ($0.032) per 40-pound standard field box, or the equivalent
thereof, of all types and varieties of citrus, as defined by the California Citrus Research Program,
marketed by producers and received by handlers or processors during the season. The
assessment rate for the 2022-2023 marketing season is two-tenths of one cent ($0.002) per
standard field box higher than last season’s rate.

In order to facilitate the collection of assessments, each handler or processor of California citrus is
required to remit assessment payments to the Board office on behalf of producers from whom they
receive citrus, including their own production. In turn, handlers and processors are authorized to
deduct such assessment payments from any money owed to such producers. Assessment forms
and additional instructions for reporting and remitting assessments on behalf of producers will be
provided to all citrus handlers and processors by the Board office.

Funds generated by this assessment are used to conduct general production research, a variety
improvement research program, a quality assurance program on agricultural chemical residues,
pest and disease control functions, and other activities pertinent to the California citrus industry.

If you have any questions regarding this assessment rate or the activities of the California Citrus
Research Program, please contact Marcy Martin, President of the Citrus Research Board, at (559)
738-0246, or Steven Donaldson with the Department’s Marketing Branch at (916) 900-5018.

Confirmation of New Citrus Virus in California

By Citrus Insider

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has confirmed positive identifications of Citrus yellow vein clearing virus (CYVCV) in the city of Tulare detected during California Department of Food and Agriculture’s (CDFA) routine multi-pest survey. This is the first detection of CYVCV in the United States. CDFA is surveying for the disease in Tulare County residential and commercial properties and will survey in Fresno and Kings counties in the coming months to fully determine the extent of the disease’s presence (which is currently limited to the city of Tulare). The survey results will inform the regulatory approach taken by CDFA and APHIS.

CDFA began initial delimitation survey work in March in a 1-mile core radius area around the initial find site. Since then, CDFA has conducted additional surveys in the surrounding areas, which have resulted in additional CYVCV confirmations in the city of Tulare, expanding the survey area. CDFA is conducting these surveys to gain knowledge on the extent of the infestation and potential impacts of CYVCV, and surveys will be ongoing for the near future. Since the detection of this virus is new to the United States, these learnings – CDFA’s robust pest prevention system that focuses on exclusion and monitoring, as well as CDFA and USDA’s experience responding to other vectored disease threats – will be critical in developing an appropriate regulatory response.

CYVCV can be spread by vectors as they move from tree to tree feeding on foliage. The vectors include citrus whitefly, green citrus aphid, melon or cotton aphid, and cowpea aphid, which are all known to be present in California. CYVCV can also be spread through grafting and the movement of infected propagative materials and rootstocks, or contaminated tools and equipment. While there is no treatment for CYVCV, as of now the best mitigation measure is to control the vector and sanitize tools and equipment. To the greatest extent possible, growers are encouraged to urge their field crews to clean and sanitize all their equipment thoroughly in between jobs or when moving between groves.

For any questions about CYVCV, please call the CDFA Pest Hotline at 1-800-491-1899 or contact your local Grower Liaison.

New HLB Research Lab Opening For Citrus

Citrus industry, UC Riverside Celebrate Opening of New Research Lab

By Alyssa Houtby, CA Citrus Mutual Director of Government Relations

Recently, leaders from the California citrus industry and the University of California, Riverside gathered to celebrate the grand opening of a Biosafety Level-3 Lab that will be used by researchers to identify a cure for the devastating citrus plant disease Huanglongbing, or HLB.

The state-of-the-art lab is the product of a partnership between the State’s citrus growers and UC Riverside aimed to protect California citrus trees from the deadly citrus plant disease Huanglongbing, or HLB.

“HLB is the single greatest threat to the future of the California citrus industry,” says CCRF Board Chairman and General Manager Booth Ranches LLC, Dave Smith. “The Biosafety Level-3 Lab is a testament to the industry’s proactive and optimistic spirit. In a matter of months, the citrus industry raised over $8 million to fund the construction of this facility and now, together with our partners at UC Riverside, we are one step closer to finding a cure for HLB.”

Located just 2-miles off campus on Marlborough Avenue, the lab will allow researchers to conduct work with plant pathogens that previously couldn’t be done in Southern California.

Construction of the $8 million lab began in 2016 and was entirely funded by the California Citrus Research Foundation through donations by citrus growers and packers.

The grand opening was marked by a ribbon-cutting ceremony and Citrus Industry Appreciation Luncheon at which several university, government, and citrus industry leaders spoke about the significance of the lab to the future of the California citrus industry.

The disease, spread by an invasive insect called Asian citrus psyllid, has been detected in over 1,500 backyard citrus trees in Los Angeles, Orange, and Riverside Counties. Citrus growers are proactively working to keep the disease out of commercial citrus groves until research finds a cure.

Casey Creamer, President of the non-profit grower advocacy group, California Citrus Mutual outlined the scope of the challenge and the extensive effort by citrus growers, federal, state, and local governments, and homeowners to protect all citrus trees.

“California is the largest citrus-producing region in the world that has not been ravaged by HLB. For over a decade, growers have worked proactively to protect the state’s $3.3 billion citrus industry and the millions of citrus trees in backyards. The construction of this lab and the partnership with UC Riverside is a significant milestone in the fight to save California citrus,” said Creamer.

Also represented at the event was the industry-funded Citrus Research Board (CRB). “The industry has invested millions of dollars over the past 10 years into research on Asian citrus psyllid and HLB,” said CRB Chairman Dan Dreyer. “However, research is useless without partners. I’m confident that the partnership between the Citrus Research Foundation, UC Riverside, California Citrus Mutual, and the Citrus Research Board will deliver actual solutions to the industry’s greatest challenge.”

UC Riverside has a long history of collaboration with the citrus industry and is home to the Citrus Variety Collection, the Citrus Clonal Protection Program, and the Citrus Experiment Station which was founded in 1907.

“We are proud to continue the tradition of collaboration and partnership with the citrus industry as we work together to find solutions to HLB,” said UCR Chancellor Kim Wilcox. “Citrus is an iconic part of California’s history, and the Biosafety Level-3 Lab is a natural extension of the mission of UC Riverside to enrich the state’s economic, social, cultural, and environmental future.”

The event was emceed by the Citrus Research Foundation Executive Director Joel Nelsen who praised the industry for its foresight and investment in research. “For over 10 years, citrus growers have partnered with government, homeowners, and the University to prevent HLB from taking hold. The construction of the Biosafety Level-3 Lab and our partnership with UC Riverside is an investment in the future of California citrus. I’m confident now more than ever that our future is bright.”

The collaboration between citrus growers and UCR drew praise by a number of local elected officials as well as State and Federal representatives in attendance.

“Not only does this lab pay homage to Riverside’s rich history in citrus cultivation and research dating back to the establishment of the Citrus Experiment Station in 1907, it builds upon that history to push us to the forefront of research critical to the survival and success of citrus cultivation in the state and nation,” stated Senator Richard D. Roth. “Thank you to UC Riverside, the California Citrus Research Foundation, and others in the industry for your partnership in this critical investment!”

Congressman Ken Calvert, unable to attend the event in person, said in a prepared statement, “The threat Huanglongbing poses to California’s commercial citrus industry cannot be overstated. The opening of the Biosafety Level-3 Laboratory for Huanglongbing Research at UC Riverside is welcome news and a critical step towards protecting our citrus from this devastating disease. All of our citrus stakeholders, including the federal government, must continue to provide the research resources necessary to end this existential threat.”

Four researchers have been approved to begin work in the Biosafety Level-3 Lab. The Citrus Research Foundation and UC Riverside will oversee the current projects as well as the selection of future projects.

Produce Passes All Residue Testing in 2017

FDA Produce Residue Sampling “Once Again” Verifies Safety

Last week the Federal Food and Drug Administration (FDA) released its 2017 pesticide residue sampling data results. FDA concluded: “The latest set of results demonstrate once again that the majority of the foods we test are well below the federal limits set by the Environmental Protection Agency.”

Note the term “once again” in FDA’s statement. They used it because government residue sampling data year after year reaffirms the safety of our food and the exceptionally high level of compliance among farmers with laws and regulations covering the use of organic and conventional pesticides.

Let’s get a little technical for a moment and focus on how FDA residue sampling is protective of consumers. FDA employs a three-fold strategy to enforce the Environmental Protection Agency’s (EPA) tolerances or safety standards for pesticide residues.
If you haven’t heard – September is National Fruit and Vegetable month. Yes, it is time to celebrate the only food group health experts and nutritionists agree we should all eat more of every day for better health and a longer life.
While decades of studies have shown the nutritional benefits of fruits and vegetables are overwhelming and significant, the safety of both organic and conventional produce is also impressive. Government sampling data shows an over 99% compliance rate among farmers with the laws and regulations required for pesticide applications on organic and conventional fruit and vegetable crops. This led the United States Department of Agriculture to state that: “The U.S. food supply is among the safest in the world.”

Many health organizations are promoting National Fruit and Vegetable month to remind consumers about the importance of increasing consumption – only one in 10 of us eat enough of these nutrient-packed foods each day.

However, studies show a growing barrier to consumption is fear-based messaging which inaccurately calls into question the safety of the more affordable and accessible fruits and veggies. This messaging is predominantly carried by the same activist groups year after year despite studies which show that “prescriptions” for fruits and veggies could reduce health care costs by $40 billion annually. Or that 20,000 cancer cases could be prevented each year.

Marcy Martin To Head Citrus Research Board

Martin Selected Following Year Long National Search

Marcy L. Martin was named today as the new president of the Citrus Research Board (CRB). The appointment was announced by CRB Chairman Dan Dreyer, who said that Martin was selected after a nearly year-long national search for the very best candidate to lead the organization.

Martin joins the CRB with more than 25 years of experience with California commodity organizations. She most recently served for 14 years as director of trade for the California Fresh Fruit Association (CFFA), where she advocated on behalf of the state’s fresh grape, blueberry, pomegranate and deciduous tree fruit production in governmental, legislative and policy issues. Prior to that, she had been controller of the California Apple Commission for ten years.

In 2015, then U.S. Department of Agriculture (USDA) Secretary of Agriculture Tom Vilsack appointed Martin to the Agricultural Technical Advisory Committee (ATAC) for Trade in Fruits and Vegetables. In his announcement, Vilsack said of those who were appointed, “They are an invaluable asset as we work to enact trade agreements and trade policies that deliver the greatest economic benefit for U.S. agriculture and for our nation as a whole.”

“California’s citrus growers, packers and shippers have demonstrated through their keen understanding that an industry must invest in sound research to meet the challenges of a constantly evolving environment, marketplace and consumer,” said Martin. “The Citrus Research Board, industry, staff and research community have stepped up to take on looming challenges, specifically huanglongbing, that have devastated citrus production within other regions, both domestically and globally. This is an area I am passionate about, and I look forward to bringing my experience in the technical and regulatory arena to the team.”

Dreyer said, “The Board is pleased to have Marcy Martin taking the helm of CRB. Her extensive experience with commodity organizations and local, state and federal regulatory agencies will be a key ingredient to the success of CRB projects and priorities. She comes to the CRB with extensive knowledge of fresh tree fruit production and the agricultural use of plant protection products. Our Board members were impressed by her dedication to and passion for agriculture.”

“The California citrus industry is an important economic contributor and an icon of the Golden State,” Martin said. “Citrus is part of our American and Californian agricultural footprint – a commodity we need to preserve and foster. I’m honored to be part of this continuing tradition.”

Martin officially will join the CRB on October 1 and will be based out of the CRB headquarters in Visalia, California. She will take the reins from Interim President Franco Bernardi.

“We cannot thank Franco enough for his dedicated service to the CRB throughout the past year,” said Dreyer. “He did an excellent job in guiding the organization through a challenging period, and the Board has been truly grateful for his leadership.”

Action Needed to Amend SB1

Urge your Representatives to AMEND SB 1

From California Citrus Mutual

This week the Assembly will consider Senate Bill 1 by Senate Pro Tem Toni Atkins.

SB 1 proposes dangerous changes to how the state implements the Endangered Species Act (ESA) and will have devastating impacts on how water is managed in California.

The bill seeks to preserve environmental regulations against perceived rollbacks by the Trump Administration by empowering state agencies to immediately adopt the “baseline” standard in place before January 19, 2017 (the day before President Trump was inaugurated).

As currently written, SB 1 would lock in the existing biological opinions that determine how much water must flow out of the Delta to protect native fish species. This directly influences how much water is available to ALL water users south of the Delta.

The State and Federal agencies are currently in the process of updating the biological opinions, which will result in lower flows and more water for communities and agriculture. But, by locking in the existing biological opinions, SB 1 prohibits State from using the best available science to manage how water moves through the Delta.

Recent amendments do not go far enough to address the ESA provisions.

California Citrus Mutual and many other agricultural and business-sector groups have proposed constructive amendments to address these concerns. The Pro Tem’s office, however, did not make substantive changes to the bill before it was passed out of the Assembly Appropriations Committee on Friday despite pressure from the Governor’s Office.

The Legislature will adjourn next Friday and it is imperative that SB 1 be amended THIS WEEK.

We are calling on our Assembly Members and Senators to urge the Senate Pro Tem to accept amendments to the ESA section.

Please click on the link below to send a letter to your representatives asking them to support amendments to the ESA section in SB 1.
