The Feb. 9 forecast for the 2023–24 orange crop in the São Paulo and West-Southwest of Minas Gerais citrus belt of Brazil is unchanged from December 2023 at 307.22 million boxes of 40.8 kilograms each. This represents a reduction of 0.7% when compared to the initial forecast for the season. Of the total estimated production, approximately 27.76 million boxes are …
By Tripti Vashisth Canopy health of HLB-affected citrus has been directly related to disease severity, fruit drop and overall fruit production. Some success has been found with the use of certain plant growth regulators (PGRs) such as gibberellic acid (GA) and 2,4-dichlorophenoxyacetic acid (2,4-D) to achieve healthier trees with reduced fruit drop and increased production. HLB MANAGEMENT Application of these …
By Frank Giles The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has established itself as a leader in new technological frontiers like artificial intelligence (AI). In fact, the school has the 15th most powerful computer in the world. The HiPerGator, as the computer is called, will assist in AI development and on many other technological fronts. Another …
The quest for long-term solutions to HLB is well underway. Technology like CRISPR is being developed to introduce tolerance or resistance to HLB. Conventional breeding also is seeking rootstocks and varieties that can resist the disease. In the meantime, growers are reminded to utilize available tools that help trees remain productive in an HLB environment. During the August Citrus & …
John Chater has been on the job now for two years, working with growers to evaluate variety performance in field trials. In the latest All In For Citrus podcast episode, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor discusses his work, including grower collaboration to study new varieties in real-world environments. Chater also talks about …
In early December, the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) hosted its annual A.H. Whitmore Foundation Farm field tour and variety display in Groveland, Florida. The event was well attended and showcased the USDA-ARS citrus scion and rootstock breeding program. Attendees loaded up for a hayride and guided tour through the grove. One stop showcased the cooperative work the …
The updated forecast for the 2023–24 orange crop in Brazil’s citrus belt is 307.22 million boxes of 40.8 kilograms each. That’s a reduction of 2.12 million boxes, or 0.7%, from the September forecast of 309.34 million boxes. The update was issued Dec. 11 by Fundecitrus in cooperation with its partners. The forecast, by varieties, is: IMPACTS ON FRUIT SIZE In …
It’s no secret that Florida’s citrus industry has seen significant shrinkage since the advent of citrus greening in the state. In the December issue of Citrus Industry magazine, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) economist Ariel Singerman takes an in-depth look at the acreage attrition. He examines the figures by county over the past 20 years. …
Cycle 5 of the Citrus Research and Field Trial (CRAFT) new tree planting program remains open for applications until 5:00 p.m. on Nov. 30. The application can be found online here. An update has been made to the general rules, expanding the acreage of eligible projects from a maximum of 100 acres to a maximum of 250 acres. As a reminder, there is no …
By Michael Rogers Much has been discussed recently about the promise and potential of utilizing CRISPR technology to create HLB-resistant trees for Florida’s citrus growers. The primary objective in citrus gene editing is to develop new varieties that are resistant to HLB disease while remaining non-transgenic. To achieve this goal, researchers make alterations to or eliminate specific genes within the …
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 …
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 …
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 …
A survey by 15 Extension agents showed Sugar Belle mandarin to be the most cold-hardy non-satsuma citrus variety following a major freeze in Georgia in December 2022. Sugar Belle was followed in order of cold hardiness by Tango, navel oranges, Kishu and grapefruit. Shiranui was the least cold hardy non-satsuma variety. University of Georgia Extension agent Jake Price reported the …
The U.S. Department of Agriculture’s National Institute of Food and Agriculture (USDA NIFA) has invested more than $25 million in 11 projects as part of the Emergency Citrus Disease Research & Extension program. This program brings the nation’s top scientists together with citrus industry representatives to find scientifically sound solutions that combat and prevent citrus greening (HLB) at the farm level. Some of this …
By Ute Albrecht The German scientist Paul Ehrlich pioneered the research for “magic bullets” — chemicals that could kill a microorganism but did not harm the patient. He also coined the term “chemotherapy” and paved the way for developing synthetic drugs. The first synthetic antibiotic (the first sulfa-type antibiotic) to successfully treat human bacterial diseases without major side effects was …
The Citrus Research and Field Trial (CRAFT) board of directors and staff are pleased to announce that the application for Cycle 5 of the CRAFT new tree planting program is now available online. Any interested commercial grower in Florida has until 5:00 p.m. on Nov. 30 to apply. The CRAFT board of directors, with the help of the Technical Working …
Citrus breeders at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) have been making a big push for four years to develop new orange varieties for processing. The need for the push was accentuated last year by a multitude of adverse situations on the processing side of the business. In a recent virtual presentation, UF/IFAS plant breeder …
By Fernando Alferez, Daniel Boakye, Murillo De Sousa and Pablo Orozco After HLB was first detected in Florida, increase in disease-associated preharvest fruit drop in affected trees has significantly reduced grower returns. Fruit drop is normal in healthy citrus, accounting for 10% to 15% of the total crop. However, under endemic HLB conditions and depending on the variety, crop loss …
Using the plant growth regulators (PGRs) gibberellic acid (GA), 2,4-D and cytokinin in combination can maximize the benefit for HLB-affected trees, researcher Tripti Vashisth reported recently. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of citrus horticulture and production works at the Citrus Research and Education Center in Lake Alfred. She discussed the benefits of …
