By Jude Grosser, Maria Brenelli, Ling Liu, Yu Wang and Fred Gmitter The combination of HLB and hurricane Ian have made this a disastrous year for Florida citrus, drastically reducing the quantity and quality of processing oranges. Brix values are the lowest in history. Early-season Hamlin juice with inferior quality is generally blended with late-season Valencia to achieve the target …
Arnold Schumann, a professor of soil fertility and water quality with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), led the effort to study the effectiveness of citrus under protective screen (CUPS) in protecting trees from HLB. The work resulted in growers having confidence in the practice. Today, Florida CUPS plantings are closing in on 1,000 commercial …
Mixon family members were pioneers in the Florida blueberry industry. Brothers Jerry and Keith Mixon planted their first berries in 1993. Over the years, they grew their business and became worldwide marketers, eventually adding blackberries, raspberries and strawberries to their portfolio. BACK TO CITRUSIn 2011, they sold their berry business to the Dole Food Company. But the brothers still had …
By Fernando Alferez Five years of University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) data in trials across the state have shown that individual protective covers (IPCs) are effective in preventing HLB until they are removed. This has been shown in sweet orange varieties such as Valencia and Hamlin. In these varieties, it has been demonstrated that the …
By Xixuan Tang, Yu Wang, Fred Gmitter and Jude Grosser Citrus fruits and juices are commonly consumed worldwide due to their health benefits and flavor. However, recent trends in reducing carbohydrate intake have raised concerns from consumers about citrus products because of their relatively high levels of sugar content. This concern discourages repeat purchasing and consumption of citrus fruits and …
By Nian Wang How the huanglongbing (HLB) pathogen Candidatus Liberibacter asiaticus (CLas) causes damage to infected citrus trees has been widely debated. A recent study demonstrates that HLB is an immune-mediated plant disease (Ma et al., 2022). It was discovered that CLas infection of citrus stimulates systemic and chronic immune response in phloem tissues, including reactive oxygen species (ROS) production, …
After HLB disease was first found in Florida in 2005, many people were discouraged from growing citrus in their home landscapes. There were no citrus recommendations tailored for home gardeners in the HLB era. Now, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has responded to home gardeners who want to plant citrus trees again. Researchers are …
Allowing citrus hybrids with certain criteria in orange juice (OJ) was one of several issues addressed in a recent workshop about potential changes to OJ’s standard of identity. Peter Chaires, executive director of the New Varieties Development and Management Corp., discussed benefits of increasing the hybrid allowance in OJ. Chaires presented a consumer study of juices conducted by University of …
Researchers will assess 20 to 30 Florida citrus groves impacted by 2022’s Hurricane Ian to learn lessons that will help growers in the future. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers Christopher Vincent and Tripti Vashisth and their teams will conduct the assessment. The research will be funded by a $280,000, one-year grant from the U.S. …
Researchers and growers have found that individual protective covers (IPCs) can keep young trees free of HLB for two or more years while providing additional benefits like improved tree growth. The IPCs work by keeping HLB-infecting Asian citrus psyllids out of the tree canopies. But trees outgrow the covers and must eventually be removed. Researchers have found that about 60% …
“To some extent, every citrus variety has suffered from cold damage” due to the five-night freeze event that occurred in the cold-hardy citrus region Dec. 24–28. That report comes from Jake Price, Lowndes County Extension coordinator for University of Georgia Extension. “The site of our citrus research plots in Valdosta reached a low of 16 degrees, which is the lowest …
By Rhuanito S. Ferrarezi and Mark A. Ritenour Two independent trials were conducted under a commercial citrus under protective screen (CUPS) system. The first trial was to investigate canopy management strategies to improve fruit yield and quality of mandarins. Canopy management is essential for CUPS since the environment stimulates vigorous vegetative growth, posing operational challenges to mechanization that can be …
B9-65 Valencia received much attention from horticulturist John Chater during a virtual meeting highlighting HLB-tolerant citrus varieties developed by the Citrus Research and Education Center (CREC) Plant Improvement Team. Chater is an assistant professor at the University of Florida Institute of Food and Agricultural Sciences CREC. ORANGESAccording to Chater, pound solids per acre and yield per acre are the most …
“Hurricane Ian has devastated much of Florida’s citrus industry,” said Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center. “The harsh reality is that the 2022–2023 season will be one of the most challenging that any of us has faced.” Several UF/IFAS Extension agents made early assessments of the …
By Arnold Schumann, Laura Waldo, Chris Oswalt, Napoleon Mariner, Timothy Ebert, Perseveranca Mungofa, Shankar Shrestha and Laura Cano-Castro Florida grapefruit production for the 2021–22 season was 92% less than in 2003–04, which was prior to the arrival of huanglongbing (HLB) disease [Source: U.S. Department of Agriculture National Agricultural Statistics Service, (USDA NASS)]. The decrease in Florida tangerine production for the …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP Just as HLB can affect fruit flavor, so can our numerous innovations to manage HLB. Yu Wang works to make sure our solutions are sweet. When the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hired her as a flavor chemist seven years ago, Wang worked primarily with breeders. Her objective was …
By Fernando Alferez, Daniel Boakye, Susmita Gaire and Tim Gast Growing citrus under protective screen (CUPS) structures for fresh fruit production is effective in controlling HLB disease by completely excluding the Asian citrus psyllid (ACP, Diaphorina citri). After several years of research on CUPS to grow HLB-free trees in Florida, and with commercial growers increasingly adopting this technology, there is …
By Jude Grosser, Manjul Dutt and Fred Gmitter Exploiting citrus genetic diversity is the key to defeating HLB. Plant species have survived for millennia with evolving, hostile pathogens. This is possible through natural selection within genetically diverse populations. Tolerant or resistant individuals survive and intermate, get through the bottleneck, and the species evolves. Current citriculture is based on extremely limited …
By Jude Grosser and Fred Gmitter New sweet oranges and sweet orange-like hybrids could offer improved juice quality for growers. It’s no secret that the recent season in Florida was a disaster, with record low production and terrible fruit quality due to HLB. Juice Brix and soluble solids were so low that harvest was delayed in many groves, resulting in …
By Anirban Guha and Christopher Vincent A quick body temperature test is common these days before entering many workplaces, hospitals and clinics due to the ongoing COVID-19 pandemic. The purpose is to screen people for fevers, usually with a non-contact infrared thermometer. Measurement of plant body temperatures also has become common for many field crops, not to screen for infectious …
