University of Georgia (UGA) County Extension Coordinator Jake Price recently provided an update on a row of Sugar Belles planted at a Georgia research plot in 2018. The Sugar Belle planting originally had 20 trees on four different rootstocks. Each rootstock was replicated five times. The rootstocks used were US-852, US-942, US-897 and Rubidoux. “After the December 2022 freeze, the …
A survey by 15 Extension agents showed Sugar Belle mandarin to be the most cold-hardy non-satsuma citrus variety following a major freeze in Georgia in December 2022. Sugar Belle was followed in order of cold hardiness by Tango, navel oranges, Kishu and grapefruit. Shiranui was the least cold hardy non-satsuma variety. University of Georgia Extension agent Jake Price reported the …
Sugar Belles on four different rootstocks in Georgia showed different levels of damage from the December 2022 freeze, reported Jake Price, Lowndes County Extension coordinator for University of Georgia Extension. The Sugar Belles at a Valdosta research plot planted in 2018 have put on the first flush of foliage after being mostly defoliated. The trees are snuggly located between windbreaks …
A pitch for potentially using the HLB-tolerant Sugar Belle® mandarin hybrid in orange juice (OJ) has been made by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers. A brief presentation titled, “Potential of Using HLB-Tolerant Sugar Belle® in Orange Juice Processing and Effects on Consumer Preference,” is available for viewing. Slides in the presentation indicate that a …
By Yu Wang, Xixuan Tang, Charles Sims, Zhifeng Gao and Renee Goodrich Citrus fruit produced from HLB-affected trees are green and taste bitter. They are usually not suitable for either the fresh market or juice market because they have a lower Brix/acid ratio. Mitigation strategies can cause less fruit drop and help citrus trees survive. However, they triple production costs, …
By Yu Wang, Charles Sims, Zhifeng Gao, Lisa House, Frederick Gmitter and Jude Grosser The citrus industry has faced significant declines in both production and consumption during the huanglongbing (HLB) era. For example, Florida orange production has dropped about 70 percent over the last two decades. In the absence of effective interventions, the spread of HLB will continue to reduce the …
During our quick ag tour last week with Max Armstrong and his television crew for “This Week in Agribusiness,” we spent some time with Fred Gmitter in one of the experimental plots at University of Florida’s Citrus Research and Education Center in Lake Alfred. We posted this interview as part of that tour series, but we’re reposting it here to …
Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) have discovered new, natural sweeteners in citrus for the first time. This finding opens opportunities for the food industry to produce food and beverages with lower sugar content and lower calories while maintaining sweetness and taste using natural products. Yu Wang, associate professor of food science at …
Minimal satsumas this harvest season will impact cold-hardy producers far beyond the loss of production in the region. MAINTENANCE MANDATORY Growers are now tasked with maintaining their groves when there is little to no fruit on the trees. It is a chore that producers should still follow through on, however, says Jake Price, University of Georgia (UGA) area citrus agent. …
A presenter at the recent Citrus & Specialty Crop Expo said oxytetracycline (OTC) trunk injections improved fruit quality in several citrus scions that were studied. The presenter was John Chater, assistant professor and citrus genetic improvement horticulturist with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center. Chater opened his presentation with these …
Citrus under protective screen (CUPS) performance in Florida got a big thumbs up from researcher Arnold Schumann in a virtual presentation on Aug. 7. Schumann, a University of Florida Institute of Food and Agricultural Sciences professor, reported on findings from his research at the Citrus Research and Education Center (CREC) as well as commercial CUPS in Florida. Schumann’s summary of …
By John M. Chater Citrus tree trunk injection of antibiotics has been recently and widely used in Florida. The success of oxytetracycline (OTC) in sweet orange to mitigate huanglongbing (HLB or citrus greening) disease has been documented by the laboratory of Ute Albrecht, associate professor at the University of Florida. Some results suggest that OTC injection can improve Brix, ratio, …
Growers use the citrus under protective screen (CUPS) production system to protect trees from the Asian citrus psyllid, the insect vector of HLB disease. While grapefruit is most commonly grown in CUPS, statistics support the belief that CUPS can be conducive to other types of citrus. “There’s a need to establish the growing requirements and the needs of other varieties. …
Citrus trees used to be a common site around Florida homes, but diseases like canker and greening have diminished residents’ ability to enjoy these iconic trees. Despite the challenges, people from Florida and across the country contact citrus nurseries this time of year, seeking to purchase trees for their yards and/or homes. It’s a passion, say nursery owners and University …
By Peter Chaires Many have been following the development of the Georgia citrus industry with great interest and curiosity. Though satsuma remains the dominant fresh citrus crop, other varieties are in varying stages of trial and adoption. The University of Georgia (UGA) has been supporting citrus growers in this process for more than a decade. Wayne Hanna, though his appointment …
Jake Price with University of Georgia (UGA) Cooperative Extension recently described Hurricane Helene damage to the UGA citrus research plot. His observations, slightly edited, are as follows: When I had a chance to look at our citrus research plot, I expected the worst. But to my surprise, all of the trees were still standing. There was limb breakage due to …
By Tripti Vashisth, Jeff Brecht, Yu Wang and Faisal Shahzad In the last decade, fruit quality and size has become a major issue. Moreover, fruit peel color is another challenge to overcome for citrus growers who intend to sell for fresh fruit consumption. Many nutrients are known to improve fruit growth and quality in citrus trees. For example, potassium increases …
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 …
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 …
The pros of using interstocks for HLB management seemed to outweigh the cons, based on a presentation horticulturist Manjul Dutt made at this spring’s Florida Citrus Growers’ Institute. Dutt is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor. An interstock is a graft of a citrus selection that can be used as a bridge between …
