Sixty‐two citrus rootstock and scion breeders, university administrators, citrus industry representatives, federal government officials and citrus research funding agency representatives met in Denver, Colorado to discuss barriers and find solutions to achieve more effective coordination and collaboration among citrus breeder scientists working on huanglongbing (HLB) mitigation. Participants identified four major areas of barriers based on the whole group’s discussion of the pre‐workshop survey: 1) Scientific Barriers, 2) Regulatory Barriers, 3) Intellectual Property and Tech Transfer Barriers and 4) Funder‐related Barriers. This final report outlines their findings and next steps to achieve more effective coordination and collaboration among citrus breeder scientists working on HLB mitigation.
NEW STUDY REVEALS CALIFORNIA CITRUS ECONOMIC IMPACT
Citrus Research Board Quantifies Industry Importance
May 16, 2018 – Visalia, Calif. – The total economic impact of California’s iconic citrus industry is $7.117 billion according to a new study commissioned by the Citrus Research Board (CRB).
“In updating our economic analysis, we selected a well-known expert, Bruce Babcock, Ph.D., a professor in the School of Public Policy at the University of California, Riverside, to conduct the research. His findings quantified the significant impact of citrus on California’s economic well-being,” said CRB President Gary Schulz.
According to Babcock, the California citrus industry added $1.695 billion to the state’s Gross Domestic Product (GDP) in 2016. “California citrus is a major contributor to the economic value of the state’s agricultural sector and is much larger than just the value of its sales,” he said. “Estimated full-time equivalent California citrus jobs totaled 21,674 in 2016-17, and estimated wages paid by the industry during that same timeframe totaled $452 million.”
Babcock added, “The application of management skills and capital equipment to efficiently utilize land and water to produce high-quality citrus also generates upstream and downstream jobs and income that magnify the importance of citrus production beyond its farm value.”
In 2016-17, the most recent marketing year of data compilation, Babcock found that the total direct value of California citrus production was $3.389 billion. This value generated an additional $1.263 billion in economic activity from related businesses that supplied materials and services to the citrus industry. Layered on top was another $2.464 billion in economic activity generated by household spending income that they received from California’s industry, according to Babcock, thus rendering a total economic impact of $7.117 billion.
The study revealed that 79 percent of California’s citrus was packed for the fresh market and 21 percent was processed in 2016-17, which is economically significant because fresh market fruit has a higher value than processed fruit.”
Of further note, California produced about 95 percent of all U.S. mandarins in the most recent reporting season.
California Citrus Mutual President Joel Nelsen commented, “The “wow” factor in this report is something as it relates to gross revenues and positive impact for the state, people and local communities. This enthusiasm must be tempered by the fact that huanglongbing (HLB) can destroy all this in a matter of a year if the partnerships that exist between the industry and government cannot thwart the spread of this insidious disease. Just this week, coincidentally, Brazil authorities reported a 20% reduction in fruit volume. Reading how that would affect our family farmers, employees and the state is sobering.”
The CRB study also looked at the possible impact of a potential 20 percent reduction in California citrus acreage or yield or a combination of the two that could result from increased costs associated with meeting government regulations, combatting the Asian citrus psyllid (ACP) and warding off the invasion of HLB, a devastating disease that has decimated citrus production in many other growing regions such as Florida. Babcock calculated that such a reduction could cause a loss of 7,350 jobs and $127 million in associated employment income and could reduce California’s GDP by $501 million in direct, indirect and induced impacts. The CRB currently is devoting most of its resources to battling ACP and HLB to help ensure the sustainability of California citrus.
Babcock is a Fellow of the Agricultural and Applied Economics Association and has won numerous awards for his applied policy research. The economist received his Ph.D. in Agricultural and Resource Economics from the University of California, Berkeley and his Masters and Bachelors degrees from the University of California, Davis.
The CRB administers the California Citrus Research Program, the grower-funded and grower-directed program established in 1968 under the California Marketing Act as the mechanism enabling the State’s citrus producers to sponsor and support needed research.

The California Department of Pesticide Regulation (DPR), honored four organizations for their achievements in reducing risk from pesticide use in a public ceremony on February 12, 2018.
“The variety of award winners this year demonstrates that pests—both in agricultural and urban settings—can be managed successfully using effective, low-risk methods,” said DPR Director Brian Leahy. “Integrated pest management is fundamental for managing pests thoughtfully and effectively in California.”
The IPM Achievement Awards recognize organizations that use integrated pest management (IPM) to address the diverse pest management needs throughout California. IPM is a tool that allows people to manage pests by using natural and preventative strategies, and thus reduces the use of chemical pesticides. The awards will be given in the areas of innovation, leadership, and education and outreach.
The Citrus Research Board Joint Agency Biological Control Task Force was one of the four honorees.
In 2010, the Citrus Research Board (CRB) established a task force to help control an invasive insect pest called Asian citrus psyllid (ACP), a serious threat to the $3 billion California citrus industry. ACPs, which are as small as a grain of rice, can infect backyard citrus trees (and potentially commercial orchards) with a bacteria that causes a devastating plant disease called Huanglongbing (HLB), or citrus greening disease. There is no cure for HLB and it is fatal to trees. The CRB Joint Agency Biological Control Task Force was created and is comprised of the Citrus Research Board, California Department of Food & Agriculture, University of California-Riverside, the United States Department of Agriculture and Cal Poly-Pomona.
Instead of relying solely on conventional pesticides to fight this insect, the task force developed a program using natural predators as a means of reducing ACP populations. The Task Force imported, reared and studied parasitic wasps from Pakistan that kill ACPs. These wasps are a key part of the first biocontrol program that successfully targeted and reduced ACP populations in urban areas and citrus orchards while replacing large-scale, pesticide-driven campaigns in sensitive urban sites. At this time, the project has been successfully implemented in several counties, including Imperial, San Diego, Riverside, San Bernardino, Los Angeles, Orange, Ventura, and Santa Barbara counties. The Task Force was honored for innovation and leadership.
The Citrus Research Board would like to congratulate the other three honorees; Hines Landscaping San Francisco, Manteca Unified School District Operations Department and Orange County Mosquito and Vector Control District and thank CDPR for this honor.

After the CCM Citrus Showcase lunch program, stick around and hear Beth Grafton-Cardwell, Ph.D., an Integrated Pest Management Specialist with the University of California, Riverside and the Director of the Lindcove Research and Extension Center deliver a talk about the work her team has been doing studying Asian citrus psyllid (ACP) management for the past several years in southern California. Nastaran Tofangsazi, Ph.D., a post-doctoral researcher at the University of California, Riverside, has been evaluating insecticides and conducting field trials to determine the residual impact of conventional and organic insecticides. This research is supported by a Citrus Research Board (CRB) grant and a U.S. Department of Agriculture (USDA) Technical Assistance for Specialty Crops (TASC) grant. In 2017, Grafton-Cardwell was awarded USDA Multi-Agency Coordination (MAC) Group funding to hire a team of four psyllid scouts to conduct year-round monitoring of 180 commercial citrus orchards in southern California. Their biweekly sampling is ongoing in the Ventura, San Bernardino, Riverside, Temecula, San Diego, Coachella and Imperial citrus growing regions. The orchards use various psyllid management practices, including broad spectrum, soft and organic insecticide strategies. The data the psyllid scouts are collecting is providing critical information about the impact these management strategies have on the psyllid populations and assisting Task Forces and Pest Control Districts in developing effective psyllid management programs.
An important result of this research is that the psyllid is “all about the flush,” and so the heaviest psyllid populations are occurring in areas where trees are flushing continuously, such as Ventura, Riverside and San Bernardino, and lowest in the desert areas where the flush hardens off for long periods of time. Broad-spectrum, long-residual insecticides reduce psyllid densities the most, especially during the fall when conditions are most favorable for psyllids. ACP populations often start on the edges of groves, and so border treatments could be applied when psyllids begin to develop on these edges, making subsequent whole-orchard, area-wide treatments more effective.
With the assistance of Sandy Olkowski, Ph.D., at the CRB, the psyllid collections also are providing information for the team to develop a rapid presence-absence method of ACP monitoring, sampling strategies to determine if psyllids are on the borders and treatment thresholds that could be utilized by Pest Control Advisors to assist growers with psyllid management. During the CRB’s Showcase workshop, Grafton-Cardwell will provide an overview of the psyllid management tactics that currently are being conducted around the state and the level of psyllid control being achieved.
She also will discuss new tactics being developed by researchers that could be added to the grower repertoire to improve existing psyllid management programs. These include the work of Mamoudou Setamou, Ph.D., Texas A&M University-Kingsville, who is working with screened fencing along the edge of orchards, which functions as a barrier to psyllid movement into the orchard. Grafton- Cardwell further will report on the project proposed by Philippe Rolshausen, Ph.D., to study the production of “Citrus Undercover Production System” (CUPS) at the Lindcove Research and Extension Center. This project will enclose citrus in screening to protect it against psyllids and determine the cost of production and the level of productivity of the trees. Additionally, Grafton- Cardwell will provide an update on the research of Mark Hoddle, Ph.D., into the efficacy of biocontrol releases of Tamarixia in residential areas.
