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 …
For 2021-22, orange juice (OJ) production in Turkey is forecast at 10,000 metric tons (MT) by the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS). That is higher than the 2020-21 OJ production total of 9,500 MT total, and is in correlation with high production and increasing domestic demands. DEVELOPING MARKETThe amount of oranges sent to processing plants increased to …
By Megan Dewdney Last summer, I received many calls about algal spot, especially in late June to early July. Algal spot is a disease, caused by the algae Cephaleuros virescens, that occurs mostly on citrus tree limbs. Much of the year it is difficult to see because it is a gray-green color that blends into the color of citrus bark. …
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 …
In a Jan. 12 virtual Zoom seminar from Immokalee (dubbed “Zoom’okalee” in the presentation), researcher Ozgur Batuman reviewed old and new approaches to controlling HLB. The seminar was titled “Citrus Disease Trends We Should Heed: HLB, Phytophthora and Leprosis.” Batuman works for the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center (SWFREC) …
In an open letter to California citrus growers, Jim Gorden, chair of the Citrus Pest & Disease Prevention Committee, emphasized the importance of cooperation of all growers to keep huanglongbing (HLB) at bay. Growers need to work together to coordinate treatments for maximum effectiveness. “As the threat of HLB continues, industry members know that the best way to prevent HLB …
By Ramdas Kanissery Paraquat is an herbicide labeled for various crops, including citrus, for post-emergent weed control. When applied during the early growth stage, paraquat controls many annual grasses and broadleaf weeds commonly found in Florida citrus. Additionally, paraquat typically offers relatively good crop safety in citrus due to its lack of translocation in the plant. This makes it the …
By Lauren Diepenbrock Managing lebbeck mealybug has become an ongoing challenge in many citrus-growing areas of Florida. This pest expanded into 14 counties from 2019 to fall of 2021 and impacts both commercial and residential citrus. Damage includes distorted fruit and leaves, stem dieback and fruit drop. Loss of young trees can occur under extreme infestation scenarios. In addition to …
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 …
A $1.5 million emergency grant is enabling scientists in citrus-producing states to find trees tolerant to the devastating citrus disease HLB. The disease has crippled Florida’s citrus industry and has already been detected in California, which grows 80% of America’s fresh citrus. The National Institute of Food and Agriculture is supporting scientists at the University of California, Riverside (UCR); the University …
By Frank Giles Mike Aerts, Florida Fruit & Vegetable Association’s vice president of science and regulatory affairs, recently shared an update from the European Union (EU) that could impact maximum residue limits (MRLs) allowed in the 27-member-country body. MRLs govern the amount of allowable pesticide residue on a food product in order to enter a country. Because the EU has …
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 …
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 …
By Amir Rezazadeh Low temperatures can cause serious injury to leaf, wood and fruits of citrus trees. An extended freeze can kill a citrus tree. A rapid temperature decrease or a longer duration of freezing temperature can worsen the damage. Because preparation is paramount in protecting citrus trees, growers should use the Florida Automated Weather Network. The network provides information …
By Brad Turner From a family with deep Florida roots, I have over 40 years of experience in commercial citrus production. I learned the industry from the ground up by working in the family groves while studying citrus production at Florida Southern College. I have owned a citrus nursery, my own groves and a citrus caretaking business. I have also …
One instance of fruit drop is expected and needed every growing season for Florida citrus producers. A second instance, however, is unexpected, unwanted and just what growers do not need right before harvest time. HLB WORSENS DROPBut that is a scenario Florida citrus growers encounter every year. This problem has only worsened in the era of citrus greening disease, also …
The U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS) is conducting the 2021 Farm Producer Study to gain knowledge and understanding of agricultural producers and help USDA improve services to them. A brief questionnaire was mailed to approximately 75,000 U.S. agricultural producers across the country. The questionnaire, which takes no more than 10 minutes to complete, asks participants …
University of Georgia (UGA) plant breeder Wayne Hanna released three seedless citrus trees in 2016. All carry the brand name “Frost” to identify them as UGA products. There is a tangerine (Sweet Frost), a lemon (Grand Frost) and a grapefruit (Pink Frost). Earlier this year, the trio became a quartet with the addition of a navel orange (Southern Frost). Hanna says …
