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 …
By Michael Rogers The 2022–23 Florida harvest season is now behind us. Yield losses magnified by the weather events this past season position the next couple of years as “make or break” for many growers. The lingering effects of hurricane Ian will impact next season’s crop as trees continue to recover and balance out canopy regrowth with fruit production. Despite …
By Davie Kadyampakeni Nutrients are needed for optimal tree growth, fruit yields and juice quality. Any nutrient deficiencies could result in low yields and decreased revenue, so it is essential to make sure citrus trees receive adequate nutrient supplies at all times. Micronutrients, though required in minute quantities, are especially important for citrus trees impacted by citrus greening. Examples of …
Positive results from experiments with photoselective shadecloth for color break and with plant growth-promoting bacteria for tree health were reported at a June 14 citrus under protective screen (CUPS) seminar. Presenter Arnold Schumann also gave an update on the generous fruit yields being generated in CUPS. Schumann is a University of Florida Institute of Food and Agricultural Sciences Citrus Research …
The sting nematode is the most serious nematode problem in young citrus groves, nematologist Larry Duncan reported at the Florida Citrus Growers’ Institute in April. According to Duncan, long before HLB, the sting nematode was widely encountered in groves on Florida’s Central Ridge and in Polk County. The University of Florida Institute of Food and Agricultural Sciences professor said tree …
Entomologist Kirsten Pelz-Stelinski recently shared findings from trials on the use of foliar-applied and trunk-injected antibiotics for controlling HLB and the Asian citrus psyllids (ACP) that spread the disease. Pelz-Stelinski is associate center director at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) in Lake Alfred. In a May 17 presentation …
For at least the last four years, the Valencia SPB-1-14-19 orange has been the most-produced citrus variety in Florida, and US-942 has been the favored rootstock. So, it makes sense that the Valencia SPB-1-14-19 on US-942 rootstock has been the most-produced tree combination for four years running. That information was provided at April’s Florida Citrus Growers’ Institute in Avon Park …
There is some buzz among citrus growers that new HLB therapies are beginning to show positive results in trees. But visual observations of trees are subjective and can vary from grove to grove and grower to grower. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has developed a new tool for growers that will provide a more …
By Amit Levy and Tripti Vashisth Many Florida citrus growers are currently injecting oxytetracycline, spraying gibberellic acid (GA) or treating trees with enhanced nutrition. A new program offered by the University of Florida Institute of Food and Agricultural Sciences (UFIFAS) Citrus Research and Education Center (CREC) can help growers determine if these treatments are improving tree health and leading to …
Kirsten Pelz-Stelinski will become director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Mid-Florida Research and Education Center (MREC) in Apopka on Aug. 1. She is currently an entomology professor and associate center director of the UF/IFAS Citrus Research and Education Center (CREC) in Lake Alfred. Pelz-Stelinski will lead faculty, staff and students at the MREC. …
April was a busy month for citrus events with both the Citrus Growers’ Institute and the Florida Grower Citrus Show taking place. Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC), joined the All In For Citrus podcast to discuss the success of the two events. Both gatherings …
By Alessandro Franco, Faisal Shahzad and Tripti Vashisth Gibberellic acid (GA) is one of the most commonly used plant growth regulators which affects flowering, fruit and vegetative growth. Multiple monthly GA foliar applications have reduced preharvest fruit drop and increased yield in huanglongbing (HLB)-affected sweet oranges. The potential impact of these findings is huge for commercial citrus production. However, there …
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 J. Scott Angle, jangle@ufl.edu, @IFAS_VP Overnight success comes after years of hard work. In science, that means the “eureka” moment isn’t a moment at all. It comes after years of research that can cost millions of dollars. That’s a level of resources that the federal government helps deliver. We’re fortunate that the U.S. Department of Agriculture’s National Institute of …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) multi-county citrus Extension agent Ajia Paolillo recently provided information about two commercial oxytetracycline hydrochloride products approved for use against HLB. TJ Biotech LLC was the first company to receive approval from the Environmental Protection Agency (EPA) for trunk injection of this formulation. EPA granted TJ Biotech a Federal Insecticide, Fungicide, …
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 …
By Gary England, Fred Gmitter and Manjul Dutt In 2014, most groves in Central Florida had citrus greening infection rates approaching 100%, but a Lake County grower reported that some trees in his Hamlin on Swingle blocks seemed to be relatively healthy. Some visual HLB symptoms were observed on these “surviving” trees, but they did not have the massive fall …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a water and nutrient management workshop at the Citrus Research and Education Center in mid-February. In addition to seminars, a grove tour was provided to demonstrate a nutrient-rate trial currently underway at the center. Kelly Morgan, UF/IFAS professor of crop nutrition, spoke on recent activity to update citrus …
By Megan Dewdney For foliar diseases, 2022 started off easily with limited outbreaks in Florida because the spring was dryer than average. The same La Niña weather pattern responsible for the dry conditions of the last two springs is predicted to occur again this winter into early spring. The weather pattern is then predicted to become a neutral pattern with …
By Jude Grosser, Fred Gmitter and Maria Brenelli The new OLL (Orie and Louise Lee) series of sweet oranges (OLL-4, OLL-8 and OLL-20) are very high-quality processing sweet oranges that generally produce higher soluble solids and better juice color than Valencia. OLL trees are more vigorous than Valencia, and anecdotal evidence suggests they are slightly more HLB-tolerant than Valencia. Trees …
