California accounted for 62% of total United States citrus …
By Jude Grosser The ultimate solution to the HLB problem is having good rootstocks that can mitigate or eliminate the disease’s impacts in any grafted commercial scion. With this, growers could profitably grow any scion, including grapefruit, Hamlin or even Murcott. Thus, rootstock breeding efforts focus on directly screening new rootstock hybrids for their ability to confer HLB tolerance or …
The $438 million preliminary on-tree value of the 2021–2022 Florida citrus crop is 29% less than the $613 million revised value for 2020–2021, according to a federal Citrus Summary. The summary reported production, price and value of the 2021–2022 crop. It was released Sept. 7 by the U.S. Department of Agriculture’s National Agricultural Statistics Service. PRODUCTION PLUMMETS Florida’s all citrus …
California citrus acreage (bearing and nonbearing) planted in grapefruit, lemons, limes, mandarins and pummelos increased in 2022 when compared to 2020. However, the state’s orange acreage declined. That information was in the 2022 California Citrus Acreage Report by the California Department of Food and Agriculture in cooperation with the U.S. Department of Agriculture’s National Agricultural Statistics Service (NASS). Although orange …
Total citrus acreage in Florida dropped 8% in the past year, to 375,302 acres, according to the Commercial Citrus Inventory Preliminary Report. The report was released Sept. 7 by the U.S. Department of Agriculture’s National Agricultural Statistics Service. The net loss of 32,046 acres is 19,942 acres more than was lost the previous season.

Tripti Vashisth, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of horticultural sciences, has dedicated several years of research into the use of plant growth regulators like gibberellic acid (GA) to fight fruit drop in citrus. In the August All In For Citrus Podcast, Michael Rogers, director of the UF/IFAS Citrus Research and Education Center, interviewed …
A combination of gibberellic acid (GA) and 2,4-D reduced preharvest fruit drop by 18% and improved fruit size but produced no statistical effect on yield, researcher Tripti Vashisth reported Aug. 30. The combination “seems promising,” the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) horticulturist stated. The report was based on first year results from a trial of …
Over 60 citrus industry representatives gathered Aug. 25 for the 61st annual Packinghouse Day at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in Lake Alfred. They heard updates on H-2A visa options for packinghouse workforce needs, an overview of citrus fruit export requirements and an update on food safety auditing. Faculty …
The August episode of the All In For Citrus podcast takes listeners on a deep dive into the use of plant growth regulators like gibberellic acid (GA) to help fight fruit drop. The episode features an in-depth conversation between Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, and …
In the quest for better fruit retention in HLB-infected citrus, there has been a good deal of attention placed on the use of plant growth regulators to fight fruit drop. Gibberellic acid (GA) has been the focus of new research in recent years to establish refined timing of applications to optimize results in Florida citrus. Much of that research has …
By Tripti Vashisth and Mary Sutton Citrus trees affected by huanglongbing (HLB) consistently have small fruit and low fruit numbers at harvest. The low fruit numbers are largely attributed to the increased rates of preharvest fruit drop that accompany HLB. Small fruit is more likely to drop during this preharvest period, suggesting a link between fruit size and retention. To …
Alico President and CEO John Kiernan recently pointed out that the company had less orange crop decline than Florida as a whole in the 2021–22 citrus season. He noted that while the U.S. Department of Agriculture reported that the Florida crop declined 22.7% from the prior season, Alico’s decline was only 12.9%. “The company believes this lower rate of decline …
The production of oranges in South Africa is estimated to grow by 6% to 1.6 million metric tons (MMT) in 2021–22, the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA/FAS) recently reported. The area planted with oranges is expected to continue its stable growth rate, expanding by 2% to 47,750 hectares in 2021–22. Limpopo province is the leading growing region …
By Tripti Vashisth Gibberellic acid (GA) can benefit citrus trees in many ways. GA can improve vegetative and fruit growth while reducing fruit drop and flowering intensity. Evidence is mounting that repeated application of GA is needed to induce the desired positive effect on fruit growth and tree productivity. In a multiyear field trial on Valencia orange, monthly application of …
The pros of injecting the antibiotic oxytetracycline (OTC) into citrus tree trunks to combat HLB appear to be numerous, including increased fruit yield, according to scientist Ute Albrecht. On the other hand, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher only discussed one con, but it was a big one. “Trunk injections cause injury, and long-term …
