A system designed to protect citrus trees from the deadly greening disease withstood the ravaging winds of Hurricane Irma last year, University of Florida scientists say. With reinforcements installed after the storm, they’ll likely withstand even more dangerous storms. Using citrus under protective screening (CUPS), growers can keep the Asian citrus psyllids away from their trees, said Arnold Schumann, a …
A 4-year-old citrus-under-protective-screen (CUPS) trial offers hope for fresh grapefruit growers who struggle to grow fruit in the face of HLB, Arnold Schumann reports. Schumann says last season’s Ray Ruby grapefruit crop enclosed in CUPS at the Citrus Research and Education Center in Lake Alfred had 100 percent packout, even after Hurricane Irma inflicted some damage to the CUPS structure …
University of Florida Institute of Food and Agricultural Sciences researcher Arnold Schumann showed off a semiautonomous vehicle at the recent Citrus Research and Education Center 100th anniversary celebration. The vehicle is used in the center’s citrus under protective cover (CUPS) facility, designed to keep trees free of HLB-spreading psyllids. Schumann discusses the vehicle and its uses. “We designed that vehicle …
University of California (UC) scientists at the Lindcove Research and Extension Center (LREC) will soon begin to test the effect of growing citrus under protective screen (CUPS). CUPS is a proposed new method of controlling huanglongbing (HLB), or citrus greening disease, by keeping psyllids, small insects known to spread the disease, away from the trees. The test will evaluate the …
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 …
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 …
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 …
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 …
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, …
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 …
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 …
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 …
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 …
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 …
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 …
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 …
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 …
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, 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 …
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 …
