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 …
The American Association for the Advancement of Science (AAAS) has elected 19 University of Florida faculty to its newest class. The honor recognizes extraordinary impact and achievement across disciplines. Two of those honored, Lukasz Stelinski and Nian Wang, work at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center. Stelinski is a professor …
By Lauren Diepenbrock Pest management is a year-round challenge in Florida citrus. With the warm climate, pests are at the ready as soon as plant resources are available to them. With knowledge of insect and mite biology in relation to tree phenology, plans can be developed to protect fruit and maintain productive citrus trees. Populations of some highly problematic pests …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) breeders produce new citrus plants more quickly than they can figure out if consumers like how the new fruit varieties taste. In the race to create versus evaluate, creators lead evaluators by hundreds of individual plants at a time. It takes a post-doc a …
By Tripti Vashisth Since 2021, a number of Florida growers have adopted the use of gibberellic acid (GA) in their grove management programs. This widespread adoption is due to the fact that GA-treated trees show canopy rejuvenation and reduction in preharvest fruit drop, resulting in improved yields. The research on Valencia shows that the effect of GA improves over time. …
By Angela Chuang and Lauren Diepenbrock While many arthropod predator and pollinator activities benefit crop quality and yields, traditional farming environments may not be ideal habitats to support their survival year-round. For example, wild bees or flies that pollinate citrus may need other sources of nectar and pollen when citrus is not flowering. Planting wildflowers near crop fields to improve …
In the latest episode of the All In For Citrus podcast, Tripti Vashisth discusses the citrus flower bud advisory system. The service is provided by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The advisories on flowering generally start before Thanksgiving and run through the end of February or early March. “The goal of the flower bud …
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 …
By Tripti Vashisth, Faisal Shahzad and Jamie Burrow Leaf nutrient analysis is an important part of a successful citrus management program. Good fertilization practices are critical for optimal crop production, especially in HLB conditions. The two main objectives of nutrition management in citrus are 1) optimum and consistent yield and 2) building a strong tree that grows and produces year …
By Lauren Diepenbrock Pest management is an ongoing effort in Florida citrus. Taking advantage of pest life cycles has been shown to be an effective tool for reducing populations of target pests. For many citrus growers, managing impacts of the Asian citrus psyllid (ACP), the vector of huanglongbing (HLB), is part of the annual management plan. As we enter the …
The December All In For Citrus podcast includes a discussion with Michael Rogers, director of the Citrus Research and Education Center, about ongoing efforts growers are making to rehabilitate citrus groves after Hurricanes Ian and Nicole. Rogers also addressed some longer-term research being conducted by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) to develop trees that …
High yields of HLB-free fruit can hypothetically be sustainably produced in citrus under protective screen (CUPS), Arnold Schumann said at a Dec. 14 field day at the Citrus Research and Education Center (CREC). He backed that up with data showing high yields from Ray Ruby grapefruit planted at high densities and fertigated in CUPS. Trees in his CUPS facility are …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recently received a large grant from the U.S. Department of Agriculture National Institute of Food and Agriculture (NIFA). Michael Rogers provided details of the grant totaling $16.5 million during the latest All In For Citrus podcast. Rogers is the director of the Citrus Research and Education Center (CREC) in …
In the search for ways to survive citrus greening, some growers have chosen the citrus under protective screen (CUPS) system as their solution. While CUPS can be costly to construct, it has proven to effectively prevent the deadly disease. But some have asked if the structures would hold up in extreme weather and adequately protect the trees. Hurricane Ian helped …
Regular flower bud advisories from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) were restarted Nov. 21 and will be provided every other week through early spring. Associate Professor Tripti Vashisth provides the advisories. The advisories provide critical information about the intensity and time of citrus blooms. Growers use this information to determine when to spray for …
