The U.S. Department of Agriculture Agricultural Research Service (USDA-ARS) citrus scion breeding program recently rediscovered several noteworthy grapefruit cultivars at the A.H. Whitmore Foundation Farm in Groveland, Florida. Among these are the Florida Red, Red Blush and Henderson varieties. These cultivars were originally selected as long shots from the Whitmore Foundation Farm and were planted in 1986. They have survived …
CITRUS NURSERY SOURCE: What Florida Citrus Growers Are Talking About
By Peter Chaires When June rolls around, the last of the oranges are generally coming in and it’s time to reassess what worked and identify areas for improvement. Research-based entities are making every effort to steer dollars to where they will have the most immediate impact. The name of the game right now is capacity preservation. We must do what …
Citrus Juice Sales Continue to Decline
At its May 9 meeting, the Florida Citrus Commission (FCC) learned how much retail sales of citrus juice continue to decline. Florida Department of Citrus (FDOC) Director of Economic and Market Research Marisa Zansler reported on the period ending April 20. Orange juice (OJ) sales were down by 11.6%, and grapefruit juice sales were down by 9%. For the fourth …
Proper Mixing and Loading of Pesticides
By Amir Rezazadeh 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. The primary pesticide handling tasks are mixing and loading. These are also the most harmful aspects of pesticide application. Because …
A New Pest in Citrus
When it comes to talking about citrus bugs, Lauren Diepenbrock, an entomologist with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), is happy to join the conversation. And that’s just what she did in the March episode of the All In For Citrus podcast. She discussed several key pests that have been problematic for growers in recent …
Growers Must Settle for HLB-Tolerant Trees While Waiting for Resistance
The dream of citrus varieties being totally resistant to huanglongbing (HLB) disease (citrus greening) is still a distant reality for Florida growers. For now, they must depend on tolerant varieties to lessen the disease’s impact, which is widespread throughout most of the state. Michael Rogers, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center …
Studying the Mechanisms for HLB Tolerance
John Chater has been on the job now for two years, working with growers to evaluate variety performance in field trials. In the latest All In For Citrus podcast episode, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor discusses his work, including grower collaboration to study new varieties in real-world environments. Chater also talks about …
Florida Citrus Hall of Fame Inductees Named for 2024
The Florida Citrus Hall of Fame has announced its Class of 2024 inductees. They are Robert M. “Bob” Behr of New Smyrna Beach, George H. Streetman of Vero Beach and Leland K. Young, formerly of Bartow. They will be inducted March 1, 2024, along with the Class of 2023 inductees. The induction ceremonies and a luncheon will be held at …
Conclusions on Asian Citrus Psyllid Control
HLB, spread by the Asian citrus psyllid (ACP), has been the scariest and most destructive disease that Florida citrus growers have ever faced. So, it was fitting that entomologist Jawwad Qureshi made a virtual presentation about ACP/HLB on Halloween, often considered the scariest day of the year. Qureshi, a University of Florida Institute of Food and Agricultural Sciences associate professor, …
Increase Yield With Shade
By Christopher Vincent, Yu Wang and Nabil Killiny Mild shade reduces stress, increases growth and yield, and may improve pest management under huanglongbing (HLB). It reduces high temperature and water stresses. Shade also may reduce HLB transmission by making trees less visible to Asian citrus psyllids (ACP). Shaded trees have less ACP, and shade appears to reduce the severity of …
Three New Citrus Releases From UF/IFAS
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center breeding program has released three new scion cultivars in the last year. These cultivars provide opportunities for diverse segments of the Florida citrus industry, including nurseries catering to the home landscape marketplace. The new releases demonstrate the value of a broad-based breeding program to …
HLB Tools for Today and Tomorrow
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 …
Highlights From Citrus Packinghouse Day Presentations
Trunk injection for HLB, diplodia stem-end rot (diplodia SER) and citrus under protective screen (CUPS) were among topics addressed at the recent Citrus Packinghouse Day. The event took place at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC). TRUNK INJECTION FOR HLBTrunk injection of oxytetracycline (OTC) increases tree health, fruit quality …
Doubling Down on CRISPR Research
By Michael E. Rogers We have all been waiting (and waiting some more) for new varieties to be developed that are resistant to HLB. Ten years ago, researchers thought they were really close to having new HLB-resistant varieties developed using gene-editing CRISPR technology. But as science goes, the story was much more complicated than first believed. A single edit to …
Drinking Orange Juice Lowers Dementia Risk
A recent study finds that moderate consumption of up to one cup per day of natural juices, such as 100% orange juice (OJ), lowers the risk of dementia. Inversely, consuming up to two cups per day of artificially sweetened beverages, and more than two cups per day of sugar-sweetened beverages, increases the risk of dementia. The study was published by …
Brazilian OJ Exports to United States Surge
Brazil is the world’s leading exporter of orange juice (OJ) and accounts for nearly 80% of the OJ marketed in the world. For every five cups of orange juice consumed, almost four are produced in Brazil. According to the Institute of Agricultural Economics, in the first four months of the year, São Paulo exported $682 million in juice, of which …
Sneak Peek: May 2023 Citrus Industry
Some growers are taking a closer look at citrus under protective screen (CUPS), while others have already adopted the production system. CUPS has been proven to protect trees from HLB and hurricane damage. The May issue of Citrus Industry magazine features grower brothers who are early adopters of CUPS. Jerry and Keith Mixon have 150 acres of CUPS production in …
Pest Management Findings Shared
Foliar sprays of insecticides timed to citrus flushing provided a significant reduction in Asian citrus psyllid (ACP) populations compared to standard grower practices, researcher Jawwad Qureshi reported. Timing sprays to flushing also led to a reduction in sprays, the University of Florida Institute of Food and Agricultural Sciences associate professor of entomology said in a virtual presentation on Feb. 22. …
IMG Citrus Acquires Facility and Farmland
IMG Citrus, based in Vero Beach, Florida, has acquired J&J Fresh Produce assets. These assets, also located in Vero Beach, include a new 185,000-square-foot cold storage and packaging facility and 1,000 acres of farmland in the Delta Farms Water Control District. “This is an exciting acquisition and a key component of our growth strategy,” said Melanie Ressler, co-chief executive officer …
Bugs Under the Covers
Individual protective covers (IPCs) do an excellent job keeping HLB-spreading Asian citrus psyllids (ACP) out of young citrus trees, showing a 99.6% reduction in ACP compared to control trees. But they don’t provide “one and done” pest control, according to University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock. In fact, IPCs “create a perfect environment …
