By Davie Kadyampakeni, Lorenzo Rossi and Alan Wright Huanglongbing (HLB) disease lowers tree performance by reducing water and nutrient uptake as a result of root loss. HLB-affected trees have a fibrous root loss of about 30% to 80%, which increases as disease symptoms develop in the canopy. Investigating optimal nutrient concentrations in citrus roots thus improves the understanding of HLB …
Major retailers have been asking questions about the citrus industry’s sustainability efforts. In response, a California citrus industry life cycle analysis project will quantify the net environmental benefits and impacts of citrus production in a typical year. The information will be gathered from a survey developed by researchers at the University of California, Davis (UC Davis), with support from the …
Production in the cold-hardy citrus region was under the spotlight during a recent field day in Quincy, Florida. Growers and industry leaders visited the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center (NFREC) to learn about various facets of citrus production. Topics like controlled-release fertilizers, crop diversification and implementation of artificial intelligence …
There have been signs of improvement for the Australian citrus industry in the 2023 season compared to 2022. Among other things, Citrus Australia Chief Executive Officer Nathan Hancock said fruit quality has improved this season. The tail end of the 2023 harvest has been particularly strong from a quality perspective, according to Hancock. “While the earlier fruit this season struggled …
By Davie Kadyampakeni and Megan Dewdney The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) conducted a six-year project to determine if plant nutritional fertilizer sources coupled with specific crop protection chemicals help mitigate citrus diseases. This project was conducted on a 5-acre commercial citrus grove block near the Citrus Research and Education Center (CREC) in Lake Alfred. …
By Brenda Eubanks Burnette A.B. Michael was known as the “Dean of the Citrus Industry.” His Orchid Island fruit consistently won awards for its high quality.

Citrus breeder Jude Grosser recently shared tips on tree nutrition and discussed some scion/rootstock combinations that should work well for trees producing juice oranges. NUTRITIONGrosser became very interested in citrus nutrition several years ago in an effort to keep his newly bred trees healthy in the face of HLB. The University of Florida Institute of Food and Agricultural Sciences professor …
Low temperatures and fluctuations in environmental conditions are among what researcher Ashraf El-Kereamy described as a “possible hypothesis” for the cause of lemon pitting in California’s San Joaquin Valley. Other possible causes include what he called “overdoing a good thing” such as fertilizer and irrigation, or something affecting the integrity of the lemon’s wax layers. El-Kereamy is director of the …
By Frank Giles and Tacy Callies The Citrus & Specialty Crop Expo hosted two citrus educational sessions during the Aug. 16–17 event held at the Florida State Fairgrounds in Tampa. The sessions included both long-term research aimed at delivering trees resistant to HLB as well as what growers can do today to help mitigate the effects of the disease in …

Fresh lemon production in Argentina in 2022–23 is forecast to decline to 1.65 million metric tons (MMT), down from 2.1 MMT the prior year, the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) reported recently. The decline is due to the impact of rising costs, which have prompted smaller producers to limit the maintenance needed on lemon-bearing trees and …
By Jawwad Qureshi, Lauren Diepenbrock and Davie Kadyampakeni Protecting citrus trees from the Asian citrus psyllid (ACP) is critical to reducing the spread and severity of huanglongbing (HLB) or citrus greening disease. ACP, the vector of the pathogen responsible for causing HLB in citrus, needs young shoots to develop and reproduce. The frequent availability of viable shoots in young trees …
Alico, Inc. began treating citrus trees in January 2023 with an oxytetracycline (OTC) product via trunk injection as a citrus greening therapy. “Through June 30, 2023, we have treated over 35% of our trees with OTC, which is expected to mitigate some of the impacts of citrus greening and is expected to decrease the rate of fruit drop, as well …
The 2023–2024 Citrus Production Guide will be available to growers at the Citrus & Specialty Crop Expo in Tampa on Aug. 16–17. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) publication includes the latest technical advice on HLB management, tree nutrition, grove management and other aspects of Florida citrus cultivation. The guide is a comprehensive reference meant …

By Davie Kadyampakeni Citrus trees require water to be able to carry out the natural processes of growth, making food, and developing fruit and juice. To get the water from the soil, the fibrous roots do the extraneous work of absorbing the water and carrying it via the transpiration stream to the leaves. The water in the soil is made …
