By Christopher Vincent Hurricane Helene’s path spared most of the citrus industry the kind of trouble that Hurricane Ian brought back in 2022, but Ian taught us some important lessons you can use if your trees were hit by high winds. WIND SPEED MATTERS Trees impacted by Category 3 winds were mostly defoliated, with major limbs broken and near 100% …
By Peter Chaires Each year, citrus breeding and research teams go to great lengths to host variety displays, research reviews, tours and field days. These events not only showcase the collective pursuit of industry needs and priorities, but they afford stakeholders an opportunity to monitor the progress and interact directly with scientists and support staff. This is an investment of …
With the news that oxytetracycline (OTC) has been approved for a third consecutive year of trunk injection in Florida citrus, growers are looking to optimize their applications for the coming season. The October cover story in Citrus Industry magazine aims to help growers make the most of their OTC injections. University of Florida researchers tell the good, the bad and …
Georgia’s citrus industry is growing and so are the diverse varieties producers are planting every year. Jake Price, University of Georgia citrus agent, said at the Citrus Grower’s Summer Update meeting last week in Valdosta that there were 4,400 citrus acres planted in South Georgia. At approximately 145 trees per acre, this equates to about 638,000 trees. What started out …
HLB has reduced citrus production across the board, but early varieties like Hamlin have taken an even bigger hit. Hamlin has been plagued by the disease and fruit drop, which has left a void in the juice-processing segment in the early season. Growers who have been replanting have mostly relied on later-season varieties like Valencia because it seems to be …
Fundecitrus researchers Silvio Lopes and Wellington Ivo Eduardo participated recently in the second edition of the Northeast Citrus Show in Aracaju, Brazil. Lopes gave a lecture on the two main Brazilian citrus diseases: citrus variegated chlorosis (CVC) and citrus greening. “In the orchards of Bahia and Sergipe, greening has not yet been detected, but there are psyllids,” Lopes reported. He …
The 2024 Commercial Citrus Inventory for Florida shows total citrus acreage of 274,705 acres, down 17% from the 2023 annual survey. The net loss of 57,551 acres is 14,505 acres more than was lost the previous year. New plantings at 4,751 acres are down from 2023, when 6,203 acres were planted. The inventory was released Aug. 29 by the U.S. …
Individual protective covers (IPCs), used primarily to protect young citrus trees from HLB-spreading Asian citrus psyllids, have become ubiquitous in Florida citrus groves in recent years. New University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research shows the trees grown under the IPCs also grow well for a few years after growers remove the bags. Growers typically remove …
By Amir Rezazadeh The giant swallowtail butterfly (Papilio cresphontes) is a beautiful insect, admired for its large wingspan and vibrant yellow and black coloration. However, for citrus growers, this butterfly is often viewed with less enthusiasm. The larvae of the giant swallowtail, commonly referred to as “orange dogs,” can cause significant damage to citrus trees. Understanding the nature of this …
The educational program on the first day of the Citrus & Specialty Crop Expo focused on trunk injection of oxytetracycline (OTC) being applied to citrus to treat HLB. Trees have received their second OTC treatment, and growers are hopeful trees will respond with better fruit retention and improved quality. Ute Albrecht, University of Florida Institute of Food and Agricultural Sciences …
The 2024 California Citrus Acreage Report indicates that acreage for five varieties increased from 2022 to 2024 while acreage for the state’s two orange varieties decreased during the same period. INCREASES The increases were in: DECREASES Navel oranges declined from 113,586 acres in 2022 to 112,366 acres in 2024. Valencia orange acres dipped from 26,225 to 25,297 acres for the …
Through Hort Innovation investments on behalf of growers and the Australian government, the National Citrus Repository Program has been established as an ‘insurance policy’ to protect Australia’s citrus industry against destructive, incurable diseases. The repository houses more than 120 publicly-owned true-to-type ‘foundation tree’ variety clones so growers can access clean, disease-free planting material for assured quality and yield protection. According …
By Peter Chaires The New Varieties Development and Management Corp. (NVDMC) has awarded funding to citrus projects for the 2024–25 season. Exciting things are happening in crop transformation, but significant progress is also being made in conventional breeding. The NVDMC board continues to support conventional breeding projects, each with a focus on near-term results, while still setting a foundation for …
Since no cure exists for citrus greening-diseased plants, Brazilian researchers are developing ways to modify orange trees and the environment around groves to make it harder for greening-spreading psyllids to thrive. LOCATION AND LAYOUT The ideal grove envisioned by Fundecitrus researchers, in collaboration with the Spanish National Research Council/Polytechnic University of Valencia and Durham University (England), starts with a careful …
Global production of tangerines/mandarins, grapefruit and lemons/limes is expected to climb in 2023–24, the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) reported in its Citrus: World Markets and Trade publication. TANGERINES/MANDARINS Global tangerine/mandarin production for 2023–24 is estimated up 1.2 million tons to 38.2 million tons. Here are expectations for major producing countries: GRAPEFRUIT Global grapefruit production in …
Applications are available online for Cycle Six of the traditional Citrus Research and Field Trial (CRAFT) New Tree Planting Program and Round Three of the Existing Tree Therapies Program. Growers may submit their applications until 5 p.m. on Friday, Nov. 1. The CRAFT board of directors, with the help of the Technical Working Group, has established a list of factors …
The U.S. Department of Agriculture National Institute of Food and Agriculture (USDA/NIFA) has invested more than $250 million to find a solution for HLB. One example of USDA NIFA-funded research is citrus under protective screen (CUPS). University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientist Arnold Schumann and colleagues began testing CUPS at the Citrus Research and Education Center …
There have been many challenges faced by the Florida citrus industry in its long and storied history. Innovative growers have found ways to overcome those challenges, making citrus one of the core industries in the state. Few would argue that HLB is not the biggest challenge to date, but growers continue to innovate to try to save the industry. A …
Citrus Australia has assured Australian consumers they will continue to have consistent access to orange juice made from locally grown fruit. Adverse growing conditions and the spread of the huanglongbing (HLB) disease have reduced orange production in Brazil, Florida and several other key citrus-growing regions around the world. This has created a global shortage of orange juice concentrate, prompting media …
By Peter Chaires The citrus research program at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center (NFREC) includes several projects aimed at assisting growers in the cold-hardy citrus region. Let’s take a look at what researchers are working on. EVALUATING SCIONS AND ROOTSTOCKS Presently, the citrus industry in North Florida faces …
