News for citrus growers around the globe
The European Innovation Council (EIC) Accelerator program has awarded a €2.5 million grant to Israel’s Nanovel. The company is developing autonomous robots powered by artificial intelligence (AI) for harvesting dense-canopy citrus orchards. The award also includes eligibility for an equity investment of up to €4.3 million, intended to anchor a planned funding round of approximately €8 million. Nanovel will utilize …
A newly published study suggests that the use of individual protective covers (IPCs) followed by monthly applications of homobrassinolide (HBr) after IPCs are removed is beneficial. The two-step approach can help young mandarin trees stay healthier longer and produce more fruit in Florida’s HLB-endemic environment. The study, “Combining Individual Protective Covers and Homobrassinolide Treatment Prolongs Tree Health and Increases Fruit …
By Danielle S. Williams Editor’s note: This article grants one continuing education unit (CEU) in the Core category toward the renewal of a Florida Department of Agriculture and Consumer Services restricted-use pesticide license when the accompanying test is submitted and approved. A minimum score of 70% is required to receive credit. Pesticides are vital tools in agriculture that help protect crops …
Soil microbiologist Sarah Strauss kicked off a Biochar and Compost Workshop at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in mid-July. Strauss, a UF/IFAS associate professor, focused on the importance of soil health for citrus. She began with a U.S. Department of Agriculture Natural Resources Conservation Service definition of soil health. …
By Tripti Vashisth, Taylor Livingston and Abhishek Neupane Florida citrus production occurs predominantly on sandy soils that are inherently low in organic matter and possess limited water- and nutrient-holding capacity. These soil constraints have become increasingly important in the era of huanglongbing (HLB), where compromised root systems reduce the tree’s ability to efficiently acquire water and nutrients. As a result, …
By Flavia Tabay Zambon and Paulo Eduardo Branco Paiva Florida’s citrus industry has faced severe decline due to huanglongbing (HLB, also known as citrus greening). Production has dropped 92% since the 2003–04 season, according to the U.S. Department of Agriculture Economic Research Service. Growers have relied on cultural practices, tolerant varieties and antimicrobial treatments, especially oxytetracycline (OTC), which has recently …
Citrus breeders have increased the volume of varieties in development over the years in the search for HLB-resistant lines. This work has yielded results, but also more selections for growers to evaluate. For the past several years, John Chater, University of Florida Institute of Food and Agricultural Sciences assistant professor of horticultural sciences, has been charged with acting as a …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a bamboo field day in July at Phillip Rucks Citrus Nursery in Frostproof. Scientists at the UF/IFAS Citrus Research and Education Center (CREC) have initiated several projects to evaluate bamboo varieties and production practices. Phillip Rucks has planted numerous bamboo varieties for evaluation and sells bamboo plants to …
Federal officials on July 17 announced a regulatory change lowering the minimum Brix requirement for pasteurized orange juice (OJ) from 10.5% to 10%. The final Food and Drug Administration rule making the change was to be published and take effect July 20. Florida Citrus Processors Association and Florida Citrus Mutual (FCM) first petitioned for the change in June 2022. The …
A Biochar and Compost Workshop was hosted at the University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center in mid-July. Interest in promoting soil health continues to grow in citrus and other specialty crops, so the event drew a large crowd. The workshop also drew interest because several speakers provided guidance about cost-share dollars available …
Freezing temperatures remain one of the biggest threats to citrus production, especially in Florida and other regions where sudden cold snaps can severely damage trees. New research suggests that seaweed-based biostimulants may help citrus trees better withstand freezing conditions. The study was published in Scientific Reports. It was led by Ahmed Abdullah, Shahid Iqbal, Alaiha Asif, KeAndre Leaks and Muhammad …
How much water citrus trees receive during fruit development can have a major impact on fruit size and internal quality, according to new research published in the journal Horticulturae. The study shows that while moderate water stress may improve some aspects of fruit quality, severe drought significantly reduces fruit size and can make fruit much more acidic. Researchers in China …
New research in China suggests that combining traditional color cameras with near-infrared imaging could make automated citrus grading systems much better at detecting surface defects. The technology has the potential to improve packhouse efficiency, reduce the number of defective fruit reaching consumers and help growers maximize the value of their crop. The study, published in the journal Agriculture, was conducted …
Citrus peel has long been viewed as a byproduct of juice processing, often ending up as animal feed or compost. New research suggests it may deserve much more attention. Scientists found that pectin extracted from citrus peel has excellent functional properties that could increase its value for use in food, beverage and pharmaceutical products. The study was published in the …
Grove edges, detector dogs and the California Citrus Research and Field Trials (CA-CRaFT) Program were prominent topics in a virtual presentation about California’s efforts to control HLB-spreading Asian citrus psyllids (ACP). Ivan Milosavljevic, Citrus Research Board (CRB) integrated pest management entomologist, delivered the report. His June 23 presentation was part of the 2026 CRB Webinar Series. GROVE EDGES Conventional human …
Fundecitrus Executive Director Juliano Ayres discussed the future of orange production in Brazil during the 75th-anniversary celebration of the German Fruit Juice Industry Association. The event was held in Bonn, Germany in late June. Ayres addressed the key factors expected to influence Brazilian citrus farming in the coming years, emphasizing orchard health, competitiveness, sustainability and the health benefits of orange …
A new systematic review, “Assessing the Value of Sustainability in the Citrus Supply Chain,” published in the journal Sustainability examines whether going green actually makes financial sense for citrus producers. Researchers Mariaconcetta Ganci, Mariarita Cammarata and Alessandro Scuderi from the University of Catania in Italy, along with Adriana Fazio of Colleroni LLC led the study. The research team analyzed 64 …
By Jamie D. Burrow and Tripti Vashisth The UF/IFAS Citrus Team conducts ongoing research to improve citrus production management strategies. The Citrus & Specialty Crop Expo is one of the main annual events where the team comes together to showcase the latest research and tools available to citrus growers. For more than 20 years, the citrus team has had a …
Postharvest diseases such as green mold (Penicillium digitatum), blue mold (P. italicum) and sour rot (Geotrichum citri-aurantii) cause heavy losses in citrus crops. These fungi thrive in warm, humid regions and have developed resistance to common fungicides such as imazalil, thiabendazole and pyrimethanil, driving up costs and raising environmental and regulatory concerns. A new study offers hope using a simple, …
A naturally occurring predatory soil mite may one day become another tool for helping citrus growers manage citrus nematodes without relying solely on chemical controls. That’s according to a new study published in the journal Biology by Mahmoud M. Al-Azzazy and Suloiman M. Al-Rehiayani of the Department of Plant Protection, College of Agriculture and Food at Qassim University in Saudi …
