  • California Citrus Breeding Program Receives Additional Congressional Support

    California Citrus Mutual (CCM) and Citrus Research Board (CRB) voiced support for the House Committee on Appropriations for including additional funds in the FY 2027 Agriculture Appropriations bill for the citrus breeding program in Parlier.

    Congress is allocating an additional $500,000 in federal funding, on top of the $1.5 million previously granted, to expand the program into California. If approved, the program will receive $2 million in federal funds annually, in addition to the funding it receives from CRB.

    “CRB was instrumental in developing the concept for the California-based program and was also involved in efforts to establish the nationwide program, while CCM advocated to secure funding,” said CRB President Marcy Martin. “Our two organizations working together on behalf of the industry have been instrumental in getting this program off the ground.”

    “I would like to thank our Appropriators and Committee leadership for their continued support of this vital program,” said CCM Director of Governmental Affairs Jacob Villagomez. “Finding solutions for California-specific growing patterns is an essential tool in fighting HLB for years to come.”

    The California citrus breeding program will focus on fresh market citrus. Funding will go towards research and development of citrus selections suited to California growing regions, changing climatic pressures, consumer taste preferences and resistance to pests and diseases, such as huanglongbing.

    The California program is an expansion of the existing national USDA Agricultural Research Service (ARS) citrus breeding program located in Fort Pierce, Florida, which is focused primarily on varieties optimized for Florida growing conditions. Work done through the Florida program has resulted in new varieties with higher yields, increased disease resistance, improved color, and a longer shelf life.

    The Florida and California breeding programs, along with the continued support from the University of California citrus breeding program at UC Riverside, will work together to deliver results for California-based growers.

    The California citrus breeding program is located at the USDA ARS field station in Parlier. Thanks to ongoing appropriations commitment, forward progress continues to be made with the addition of a dedicated scientist, completion of a greenhouse, and future plans for laboratory and office space, and hopefully securing additional ground for further expansion.

  • Citrus Greening Quarantine Expands in Southern California

    Effective immediately, the Animal and Plant Health Inspection Service (APHIS), in cooperation with the California Department of Food and Agriculture (CDFA), is expanding the area quarantined for citrus greening (Huanglongbing), caused by the Asian citrus psyllid, in California. APHIS is establishing a new quarantined area in the Ramona area of San Diego County of 93 square miles and is expanding the quarantined area in the Loma Linda area of San Bernardino and Riverside Counties by 26 square miles. These measures parallel the intrastate quarantines that CDFA established on March 2, and March 6, 2026, respectively. APHIS is taking this action because of citrus greening detections in plant tissue samples collected from residential properties. There are 25.16 acres of commercial citrus impacted by the new Ramona quarantine and 411.47 acres of commercial citrus impacted by the Loma Linda area expansion.

    APHIS is applying safeguarding measures outlined in 7 CFR 301.76 and Federal Orders pertaining to the interstate movement of regulated articles from the quarantined areas in California. This action is necessary to prevent the spread of citrus greening to non-infested areas of the United States.

    The APHIS Citrus Greening webpage contains specific changes to the quarantined areas in California. APHIS will publish a notice of this change in the Federal Register.

  • CDFA Expands Sweet Orange Scab Quarantine in La Puente

    The California Department of Food and Agriculture (CDFA) announced it is expanding its sweet orange scab (SOS) quarantine in the La Puente area of Los Angeles County (grids 456 and 457). The quarantine is effective as of April 8.

    SOS is believed to be caused by Elsinöe australis, a fungal pathogen. The disease results in the formation of pustules and lesions on the skin of the citrus.

    Regulated articles and conditions for intrastate movement under the quarantine can be found at Title 3 of the California Code of Regulations section 3443. Interested parties and local entities may request to lift the quarantine area designations by submitting a written appeal supported by convincing evidence. Appeals must be filed within 10 working days of the notification. Quarantines will remain in effect during the appeal’s pending. Appeals can be mailed to: CDFA – Citrus Division 1220 N. St. Sacramento, CA 95814.

  • APHIS Expands the Sweet Orange Scab Quarantined Area in California

    Effective March 11, USDA’s Animal and Plant Health Inspection Service (APHIS), in cooperation with the California Department of Food and Agriculture (CDFA), is expanding the area quarantined for sweet orange scab (SOS) in the Van Nuys area of Los Angeles County in California. SOS is a disease caused by the fungus Elsinöe australis. APHIS is expanding the quarantined area by 80 square miles in Los Angeles County. APHIS is taking this action because of SOS detections in plant tissue samples collected from residential properties in Los Angeles County. This expansion does not impact commercial citrus.

    APHIS is applying safeguarding measures outlined in Federal Order DA-2024-34 pertaining to the interstate movement of regulated articles from the quarantined areas in California. This measure parallels the intrastate quarantine that CDFA established on March 2, 2026. This action is necessary to prevent the spread of SOS to non-infested areas of the United States.

    The APHIS Sweet Orange Scab website has information on this disease, Federal Orders, APHIS approved packinghouse procedures, and a description of current Federal SOS quarantined areas.

  • Surveying Citrus Greening Risks in Southern California

    A screenshot of the risk-based survey for detecting huanglongbing (HLB) in Southern California. Colors represent the probability of HLB establishment or development, ranging from low risk (blue, near 0.0) to high risk (red, near 1.0). (Image provided by Weiqi Luo, North Carolina State University)

    Huanglongbing (HLB), also known as citrus greening, is the most devasting disease of citrus worldwide and has cost billions of dollars in economic losses. HLB has severely affected the citrus industry in Florida before any remedial action could be taken by growers. In California, HLB has been reported in urban backyard citrus trees that are a potential source of the pathogen. These infected backyard citrus trees threaten surrounding commercial citrus groves.

    ARS researchers in Fort Pierce, FL, and their research partners developed a refined risk-based survey (RBS) to help stakeholders survey for HLB in complex urban and suburban landscapes in Southern California. The RBS is being used by the citrus stakeholders and plant health regulators to identify and remove infected trees, which will help preserve the health of nearby citrus groves. Use of the model optimizes survey efforts and allocation of resources to combat HLB. The RBS is also updated with new detection data and refined continuously to better guide surveillance of HLB in Southern California. An online interface makes the most recent survey available to stakeholders.

  • Slight Citrus Production Decrease Predicted for Mexico

    In market year (MY) 2025/26, total citrus production in Mexico is expected to decrease slightly by 0.4 percent from the previous year, driven primarily by a decrease in orange production. MY 2024/25 fresh orange production is estimated down on heavy rains caused by tropical storms Raymond and Priscilla that hit main producing regions in October 2025 postponing harvesting in some areas until early MY 2025/26. Environmental factors, such as prolonged drought, extreme heat, and erratic rainfall, are expected to hamper production. Orange juice production is subsequently also projected down slightly on lower available orange supplies and inconsistent fruit quality. Exports of fresh citrus fruit are projected to maintain a relatively moderate upward trend for fresh lemons/limes and a marginal decrease for fresh oranges.

    Executive Summary:

    MY 2025/26 total production in Mexico of fresh oranges, lemons, limes, and grapefruit is expected to decrease by 0.4 percent from the previous year as Mexican citrus production remains challenged by adverse environmental conditions such as prolonged drought and high temperatures affecting many of Mexico’s key producing areas.

    Mexico’s total domestic consumption is up an average 4 percent across all fresh citrus, driven by a 6 percent increase in fresh lemon/lime consumption. However, consumer purchasing behavior continues to be primarily constrained by the economic environment. While included in the Mexican Department of Agriculture’s official basic food basket, or “canasta basica,” fresh citrus and other fruit products are generally not prioritized as staple food items by medium and low-income Mexican consumers.

    Fresh citrus fruit exports are expected to continue to rise due to a moderate increase in lemon/lime exports offsetting declining orange exports. MY 2025/26 fresh citrus exports are projected to be above MY 2024/25 exports due to higher available exportable lemon/lime supplies. Mexico’s imports of fresh citrus fruit are minimal and largely unchanged year to year. In 2024, according to Agri-food and Fisheries Information Service (SIAP), total area planted with citrus fruits covered in this report (oranges, lemons, limes, and grapefruit) reached over 604,000 hectares, a 1.2 percent increase from the previous year. Oranges make up 58 percent of total citrus planted area, lemons 38 percent, and grapefruit 3.6 percent. This distribution has remained consistent for the last 11 years.

    Planted Area

    For MY 2025/26 (November/October), Post projects orange planted area at 356,800 hectares (ha), a 0.97 percent increase from the previous year. Over the last couple of years, Mexico’s largest orange growing regions have been affected by prolonged drought, and recently in October, tropical storm Priscilla caused severe flooding in the state of Veracruz. Most of the damage took place in orange groves close to riverbanks. Additionally, HLB (Huanglongbing), also known

    as yellow dragon disease, and other pests continue to reduce yields in Veracruz and other major

    producing states.

    In general, farmers face higher operational costs, driven by increasing prices of fertilizer, electricity, and fuel. To address these challenges, large-scale growers are exploring improved post-harvest strategies as well as implementing sustainable solutions such as the use of bio-stimulant products and good agroecological practices. Across the

    country, for the last five years constant weather fluctuations like extreme heat, limited water availability, and intense downpours in short periods of time have hampered crop production and fruit quality, especially in terms of size and juice content.

    For MY 2024/25, large growers producing under irrigation systems expect their fruit to be well-sized and with more juice content but anticipate a decline in their external (cosmetic) appearance, making the fruit less attractive for the retail market. Consequently, growers often delay cutting/harvesting the fruit produced in irrigated orchards to secure a better market price with improved product quality.

    Based on available official data, Mexico’s MY 2024/25 orange planted area is estimated to be 353,342 hectares, a marginal decrease from 353,609 ha in MY 2023/24. In 2024, the majority of Mexico’s total orange planted area was concentrated in the states of Veracruz (48.6 percent), Puebla (10 percent), Tamaulipas (10 percent), San Luis Potosi (9 percent), and Nuevo Leon (7 percent). Other states combined accounted for the remaining 15 percent.

    Production

    Despite a moderate increase in planted area, Post forecasts orangeproduction for MY 2025/26 will decrease 2.8 percent from the previous year at 4.7 million metric tons (MMT) on adverse weather. In October 2025, tropical storms Raymond and Priscilla damaged many orange orchards near riverbanks in major producing areas in Veracruz and interrupted end-of-marketing year harvesting activities. Although the storms caused major fruit loss in those affected areas, many fruits remained unharvested on the trees and were unable to be harvested until November-December 2025 and thus will be counted towards MY 2025/26 production.

    Mexico’s MY 2024/25 orange production is estimated at 4.83 MMT based on available official data. This represents a decrease of 2.1 percent from the previous year’s estimated production of 4.96 MMT. Over past few years, production has been unstable due mainly to adverse environmental conditions including prolonged droughts, high temperatures, and erratic rainfall. In the current year, growers anticipate lower output and average external (aesthetic) fruit quality, although with good flavor and juice content. According to estimates from both Post and USDA official data for MY 2024/25, Mexico holds a firm fourth position in global orange production, accounting for 11 percent of the worldwide total, behind Brazil, China, and the European Union.

    Using available official data, Post estimates Mexico’s national orange yield for MY 2024/25 at 14.17 metric tons per hectare (MT/ha), a decrease of 2.2 percent from the previous year as a result of the unprecedented heavy rains in October. Post anticipates that the environmental conditions mentioned will continue to negatively affect planting, harvesting, and overall citrus yields in MY 2025/26.

    The state of Veracruz largely determines the trajectory of Mexico’s orange crop, as it accounts for almost half of the total national planted area for oranges. According to SIAP official data, orange production in MY 2024/25 is 2.1 percent lower than the 4.94 MMT crop in MY 2023/24. The decrease in volume is mainly attributable to a 23.2 percent decrease in production in Tamaulipas, the second largest orange producing state, although the loss was offset by a 1.1 percent increase in production in Veracruz and a 9.8 percent volume increase in Puebla, the third largest producer in CY 2024. In CY 2024, according to available official data, Nuevo Leon ranks fifth with 5 percent of total national orange production. Based on Mexican official available data, in CY 2024, national orange production exceeded 4.83 MMT. The Valencia orange continues to be the predominant variety with over 95 percent of national orange production followed by the Hamlin variety with 4 percent. The Marrs, Navel, and Criolla varieties account for the remaining 1 percent. The ratio among orange varieties has remained stable for many years. Based on expectations among orange growers/packers regarding current higher fresh orange retail market prices versus prices offered for fresh oranges by juice processors, the price difference could potentially lower available fresh orange inputs for the juice industry in MY 2025/26.

    Phytosanitary Issues Huanglongbing (HLB) or yellow dragon is a phytosanitary hazard to citrus growers and present in Mexico’s major citrus producing areas. To mitigate the impact of HLB, Mexico’s federal and state governments continue to work together to implement measures such as biological control and integrated pest management, in addition to training and promoting good agricultural practices.

    Consumption

    Post forecasts Mexico’s domestic fresh orange consumption at 2.7 MMT in MY 2025/26, a moderate 3 percent increase from the previous marketing year. This increase is largely due to the marketing year shift of many MY 2024/25 fruits that were delayed in being harvested due to tropical storms in October 2025. The uptick is also due to fewer fruits being destined for processing into juice as prices for fresh oranges currently outpace those offered by the juice industry, creating higher available fresh fruit supplies for consumers. However, this expected increase in consumption is likely to be curbed by economic factors that continue to affect consumers’ purchasing power. According to the Instituto Nacional de Estadística y Geografía (INEGI) in September 2025, the cost of basic food basket products increased by 3.6 percent year-over-year in rural areas, slightly below the overall annual inflation rate (3.8 percent), whereas in urban areas the increase in food basic basket products reached 4.7 percent. The rising price of food continues impacting consumers’ purchasing decisions, making them more selective when buying food items such as fruits. Oranges, for example are included in the basic food basket “Canasta Básica,” but they are prioritized lower by lower/middle class families than animal proteins such as poultry and eggs. Fresh orange consumption in MY 2024/25 is estimated at 2.61 MMT.

    Trade

    For MY 2025/26, Post forecasts Mexico’s fresh orange exports at 49,000 MT, a decrease of 9 percent versus 54,000 MT estimated for MY 2024/25 due to lower available exportable fruit and SPS-related logistical challenges for producers in Nuevo Leon. Nuevo Leon’s orange production for CY 2024 is up 7 percent from CY 2023 according to available official data; however, exporters in this region face costly logistical burdens with the cessation of APHIS’ roving seasonal inspection services in the high production area of Montemorelos a few years ago. Although Nuevo Leon borders the United States, fruit packers in Nuevo Leon must now send their shipments down south around 180 miles to San Luis Potosi to have their fruits irradiated at an APHIS-approved facility before sending them back north for export to United States, per information on SENASICA’s website Moreover, according to producers, fresh orange prices in Mexico are lucrative enough that many suppliers are choosing to sell to the local market over exporting. Consequently, Post estimates a

    drop in the volume of fresh orange exports from Mexico to the United States in MY 2025/26. Historically, the United States has accounted for over 98 percent of Mexican orange exports.

    MY 2025/26 fresh orange imports are forecast at 31,000 MT, a 24 percent increase from 25,000 MT of imports in MY 2024/25, considering the drop in domestic production volume and relatively steady fruit imports from the United States. Mexico imports fresh oranges exclusively from the United States, which go to retail and wholesale markets.

    Policy

    At the time of this report, the exportation of fresh oranges, grapefruit, and tangerines from Mexico to the United States is allowed for compliant products under current USDA/APHIS and SADER/SENASICA work plans. Since 1988, the state of Sonora has been a fruit fly-free zone according to USDA/APHIS, and fruit grown in this state is not regulated by the applicable work plans for citrus fruits.
