The advisories on flowering generally start before Thanksgiving and run through the end of February or early March. “The goal of the flower bud …
New federal funding of $1 million will establish a citrus breeding program in California. The program will be at the U.S. Department of Agriculture’s Agricultural Research Service (USDA ARS) field station in Parlier. It will identify new citrus varieties that are best suited for changing climatic pressures such as drought, consumer taste preferences, and resistance to pests and diseases such …
By Lukasz L. Stelinski, Lauren Diepenbrock and Larry Duncan Given the focus on HLB in citrus management for more than a decade, important additional pests of citrus have sometimes not received the attention they may deserve. Trees with HLB are weakened and prone to succumb to the effects of the disease when challenged by secondary affliction(s), including infestation by diaprepes …
By Lorenzo Rossi With no cure for HLB available, searching for alternative mitigation strategies is an urgent priority for a sustainable citrus industry. Interest has grown regarding the use of organic amendments to improve the fertility of Florida native soils. Although hardwood mulch applications have been demonstrated to improve both tree health and soil fertility in other fruit industries, little …
The total Brazilian orange crop for marketing year 2022–23 is forecast at 405 million boxes (MB), a reduction of 10 MB compared to the previous season. The commercial area in the state of São Paulo and the western part of Minas Gerais should account for 305 MB, a drop of 3% from the prior year. Production from other states is …
The late F. Gilbert Bowen of Winter Haven and the late A.G. Smith of Wauchula will join the Florida Citrus Hall of Fame as the Class of 2023 inductees.

Past management, a perennial problem for citrus growers, is the primary focus of the January issue of Citrus Industry magazine. An old pest is posing new concerns for Florida growers. The recent resurgence of diaprepes root weevil is the subject of the cover story by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers Lukasz Stelinski, Lauren Diepenbrock …
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 400-acre property includes 110 acres of groves on prime citrus land. Some of the state’s most popular …
The Gulf Citrus Growers Association (GCGA) hosted a luncheon on Dec. 7 at the Southwest Florida Research and Education Center featuring a presentation by Tom Johnson, chief executive officer of TJ BioTech. The company is the manufacturer of ReMedium TI, the widely discussed formulation of oxytetracycline hydrochloride (OTC-HCI) that has shown promise as a treatment for HLB. The product is …
By Thomas H. Spreen The timing of Hurricane Ian is not unlike that of Hurricane Irma in September of 2017 in that it struck before the U.S. Department of Agriculture (USDA) crop forecast was released in October, but after the data collection process was already completed for the forecast. Therefore, the USDA forecast will not take Hurricane Ian’s impacts into …
The Southwest Florida Research and Education Center (SWFREC) in Immokalee recently hosted its annual open house. The event had a great turnout of local growers and residents from nearby communities. Several school groups also attended, so students could learn more about farming in Southwest Florida and the research being conducted at the center. Originally established in 1958, SWFREC was dedicated …

Morgan, Davie Kadyampakeni and Tripti Vashisth This article reviews current University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus fertilizer recommendations and provides updated information about recently approved recommendations for secondary macronutrients and micronutrients. Citrus growers have been very concerned about fertilizer applications and nutrient management since citrus greening (huanglongbing or HLB) was found in …
The World Citrus Organisation’s (WCO) Northern Hemisphere citrus production forecast for the 2022–23 season is 25.958 million tons, a 13% decrease from the prior season. Production of every citrus variety in the Northern Hemisphere is forecast to dip by more than 11%.
