Citrus growers depend on the latest information about best irrigation and nutrition strategies for growing productive trees. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers will share recent results regarding optimal crop management at a workshop and field visit opportunity on Feb. 8 at the Citrus Research and Education Center (CREC) in Lake Alfred. Davie Kadyampakeni, assistant …
By Bill Castle, Fred Gmitter and Jude Grosser The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) plant improvement team has long been engaged in field research to evaluate new scions and rootstocks. That effort continues and has involved trials on public and private property. While public sites are valuable, they are …
Phytophthora infection can lead to severe stunting in newly planted citrus trees, researcher Megan Dewdney told growers and others at a Jan. 19 presentation at the Citrus Research and Education Center in Lake Alfred, Florida. She said stunted trees never thrive or produce adequate fruit. Dewdney is a University of Florida Institute of Food and Agricultural Sciences plant pathologist. She …
The Citrus Research and Development Foundation (CRDF) governing board on Jan. 25 approved a project aimed at reducing fruit drop by using potassium, zinc, gibberellic acid and the herbicide 2,4-D in different timing scenarios. The funding will allow University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher Fernando Alferez to finish two years of work that CRDF Chief …
It is set to be a busy legislative session for agricultural interests in Florida. One of the bills making its way through the process is SB 1002, the Citrus Recovery Act. Sen. Danny Burgess (R-District 20) introduced the bill to amend the Florida Citrus Commission (FCC). The FCC is the governing body of the Florida Department of Citrus. The Citrus …
By Jawwad A. Qureshi and Azhar A. Khan The Asian citrus psyllid (ACP), Diaphorina citri, invaded Florida over two decades ago. The need to consistently suppress it became apparent soon after detection and particularly after discovering huanglongbing (HLB) disease, which it spreads. Managing HLB depends strongly on vector control to either reduce disease transmission of healthy trees or reinoculation. Single …
Megan Dewdney told citrus growers how to give young trees a good start in the face of HLB. Her Jan. 19 presentation was held at the Citrus Research and Education Center in Lake Alfred, where she is a University of Florida Institute of Food and Agricultural Sciences plant pathologist. Trees need a robust, established structural root system before they are …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is committed to updating nutrient management recommendations for citrus. For the next two months, that means seeking state funding for the research. The UF/IFAS team was crafting a specific proposal to the Legislature as of this writing. It’s at the very top of …
By Ariel Singerman According to the U.S. Department of Agriculture (USDA), production of processed oranges in Florida will decline again this season (Figure 1). If such a forecast materializes, production will have declined by approximately 80% since HLB was first found in the state. The Florida Department of Citrus reports that, as a consequence of COVID-19, orange juice demand has …
As HLB has reduced Florida’s citrus crop, so too has the budget shrunk for the Florida Department of Citrus (FDOC). The agency charged with promoting the state’s signature crop is largely funded by fees based on citrus production. FDOC has been forced to look for creative ways to do more with less with its promotional budget. One tactic has been …
By Lukasz L. Stelinskiand Jawwad A. Qureshi Asian citrus psyllids (ACP) are at the mercy of their host (citrus) for survival. They need flush to lay eggs and for the nymphs to develop. Prior to HLB, the majority of flushing had been fairly predictable and occurred in the early spring and late summer. The occurrence of flush in young trees …
When Lindy Savelle ended her career in federal law enforcement, including stints overseas, she and her husband decided to move back to land they owned in South Georgia. They researched different crops they might grow and settled on citrus. She tells her story in a recent Grower Talks Podcast produced by the Georgia Fruit and Vegetable Growers Association. “Citrus is …
Florida citrus growers and orange juice processors are reporting low Brix levels as the 2021–2022 harvest season continues. The Jan. 10 edition of the Market News Bulletin from Florida Citrus Mutual noted average Brix of 9.83. According to Bob Behr, chief executive officer of Florida’s Natural Growers, juice oranges being harvested now are running below average. “Citrus greening continues to …
The Southeast Regional Fruit and Vegetable Conference held in Savannah in early January included a session on citrus production to educate growers. Kelly Morgan, professor of soil fertility and water management with the University of Florida, spoke to attendees about newly updated production guides and their relationship to plant nutrition and HLB. Morgan noted that the third edition of the …
As they battle HLB, growers must control costs wherever possible, including by applying pesticides and fertilizer more efficiently. With that in mind, Yiannis Ampatzidis is engaging artificial intelligence (AI) to develop a low-cost, smart tree-crop sprayer that can automatically detect citrus trees, calculate their height and leaf density, and count fruit. That way, growers target their spray more efficiently, so …
By Michael Rogers January marks the season for resolutions: exercising more, eating well and being more organized. But in the research world, resolutions may not be that simple. I don’t think that University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers could be any more “resolved” in finding ways to fight citrus diseases and ways to improve how …
By Tripti Vashisth In a multi-year field trial, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have seen beneficial effects of gibberellic acid (GA) on Valencia sweet oranges. Monthly application of GA (September to January) on Valencia improved yield on average by 30%, reduced fruit drop and elicited enhanced plant defense response. These benefits are possibly due …
By Frank Giles The U.S. Department of Agriculture (USDA) reported a drop in estimated Florida orange production in its December crop update. That estimate lowered production by 1 million boxes from the initial forecast of 47 million boxes reported in October. In advance of USDA’s January estimate, Florida citrus growers discussed how their crops are progressing. Here’s what they had …
For the first time, scientists have been able to measure the speed of the Candidatus Liberibacter asiaticus (CLas) bacteria that causes HLB disease. CLas are injected into citrus trees by psyllids feeding on the trees’ sap. CLas relies on this sap to grow and spread throughout trees. Using a new statistical modeling analysis and measurement approach, plant pathologists were …
Researchers Mark Ritenour and Sandra Guzmán with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) outline the agenda for the Florida Grower Citrus Show on Jan. 26-27 in Fort Pierce. Ritenour and Guzmán, both of the UF/IFAS Indian River Research and Education Center, will be presenters at the show. Ritenour will discuss maximum residue tolerances for fruit …
