HLB, spread by the Asian citrus psyllid (ACP), has been the scariest and most destructive disease that Florida citrus growers have ever faced. So, it was fitting that entomologist Jawwad Qureshi made a virtual presentation about ACP/HLB on Halloween, often considered the scariest day of the year. Qureshi, a University of Florida Institute of Food and Agricultural Sciences associate professor, …

Brassinosteroids Can Improve Juice Quality and Fruit Yield
By Fernando Alferez and Divya Aryal There are some indications that brassinosteroids (Brs) may advance commercial internal maturity by almost one month in Valencia sweet orange, depending on the time of application. However, the best time of application in this variety and other sweet orange varieties like Hamlin still needs to be determined, so that this treatment can become economically …
Transgenic Citrus Studies Progressing
The search for solutions to HLB has gone on for nearly two decades. Growers and researchers have learned ways to improve nutrition programs to keep trees alive and productive, but nowhere near at the level of the days before the disease. One area of research that could yield a tree resistant to HLB is genetic engineering. There are no transgenic …
Fine-Tuning Trunk Injection
Growers have concluded their first round of injecting their citrus trees with oxytetracycline (OTC) and now are anxiously awaiting the results. So far, trees seem to be responding with larger leaves and fruit, but fruit retention will tell the story if the treatment is moving the needle against HLB. For many years, there was a perception among growers that if …
Millennium Block Varieties Tour
Citrus growers are invited to tour the 20-acre Millennium Block at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC) in Fort Pierce on Nov. 7. The tour will be held from 9 a.m. to 2 p.m. New varieties in the grove are in their fourth year of growth. Researchers are …
$5 Million Awarded to UF/IFAS for HLB Research
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has been awarded five federal grants totaling more than $5 million to control HLB. The grants are from the U.S. Department of Agriculture’s National Institute of Food and Agriculture (NIFA). HLB is caused by the bacterium Candidatus Liberibacter asiaticus (CLas). The Asian citrus psyllid can transmit CLas into a …
Citrus State of the Industry Survey
There’s a lot going on in Florida citrus. New trunk-injection therapies have been approved to treat HLB as groves bounce back from last year’s hurricanes. It’s a good time to get a sense of the mood of growers as we start the new season. If you are a grower or a consultant/caretaker (who can answer generally on behalf of your …

São Paulo Governor Creates Greening Committee
The governor of Brazil’s state of São Paulo, Tarcísio de Freitas, on Oct. 16 decreed the formation of a state committee for greening contingency after meeting with several members of the state’s citrus industry. Greening affects 38.06% of orange trees in the states of São Paulo and Minas Gerais. The governor acted after considerations by the Sylvio Moreira Citriculture Center/Agronomic …
How Much Yield Is Needed to Offset the Cost of Injecting Trees With Oxytetracycline?
By Ariel Singerman Citrus growers in Florida are now allowed to inject their trees with oxytetracycline (OTC) to try to control Candidatus Liberibacter asiaticus and/or suppress citrus greening. The use of OTC is expected to improve the trees’ health and, in turn, increase yield. In this article, cost estimates are used to address the question of what yield response is …
Sneak Peek: November 2023 Citrus Industry
As the new citrus season gets underway in Florida, growers are hopeful for an improved harvest. The initial U.S. Department of Agriculture forecast for 2023–24 calls for a 30% increase in the state’s orange crop. The November issue of Citrus Industry magazine has details on the forecast and other good news for growers. In the issue’s cover story, Wheeler Farms …
Improve Fruit Yields and Juice Quality
By Davie Kadyampakeni and Megan Dewdney The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) conducted a six-year project to determine if plant nutritional fertilizer sources coupled with specific crop protection chemicals help mitigate citrus diseases. This project was conducted on a 5-acre commercial citrus grove block near the Citrus Research and Education Center (CREC) in Lake Alfred. …
All In For Citrus Podcast, October 2023
Many people believe genetics will be the eventual key that unlocks more permanent solutions to HLB. Whether it be traditional breeding or new technologies, one day there could be a citrus tree that is resistant or tolerant enough to make the disease a non-factor. One such key could be CRISPR technology to deliver a tree that is engineered to resist …
CRAFT Public Dashboard Offers a Look at Trials and Results
By Tina Buice The Citrus Research and Field Trial (CRAFT) program was created in 2019.
