Fundecitrus researchers contributed to two recent citrus gatherings in South America — the 48th Expocitrus/44th Citriculture Week in Sao Paulo, Brazil, and a CITRIBAC project meeting in Argentina. Researchers Franklin Behlau, Marcelo Miranda and Geraldo Silva Júnior, along with postdoctoral fellows Deived Carvalho and Wellington Ivo Eduardo, gave lectures on citrus-growing topics at the 48th Expocitrus/ 44th Citriculture Week. The …
By Ute Albrecht, Ankit Pokhrel, Sarah Strauss and Ramdas Kanissery The soils in most Florida citrus production areas are sandy. They have less than 1% organic matter and a low cation exchange capacity (CEC). This makes them prone to nutrient leaching, especially after heavy rainfall events in the summer. HUMIC SUBSTANCESOne way to improve soils is by amending them with …
Using drones to apply chemical control for HLB-spreading psyllids in Brazil proved effective against adult insects, a Fundecitrus researcher reported. The researcher, Marcelo Miranda, said psyllid mortality was above 80% as a result of drone applications. Miranda’s work was pioneering in 2021. There was no record of the use of drones for the chemical control of the psyllid in western …
Psyllids collected in orchards in four microregions of Brazil’s citrus belt showed reduced susceptibility to insecticides from the pyrethroid and neonicotinoid chemical groups. That information was reported earlier this year by agronomist and researcher Fernando Amaral of the Arthropod Resistance Laboratory at the Luiz de Queiroz College of Agriculture/University of São Paulo (ESALQ/USP). This was the first confirmation of psyllid …
By Frank Giles HLB has taken a toll on growers both large and small over the years. That’s been the case with third-generation grower Chuck Bellamy, who grows citrus near Inverness, Florida. His grandparents planted the first trees on the property in 1930. A few of those trees are still alive in the grove nearly 100 years later. Bellamy says …
The sting nematode is the most serious nematode problem in young citrus groves, nematologist Larry Duncan reported at the Florida Citrus Growers’ Institute in April. According to Duncan, long before HLB, the sting nematode was widely encountered in groves on Florida’s Central Ridge and in Polk County. The University of Florida Institute of Food and Agricultural Sciences professor said tree …
Hurricanes Ian and Nicole in 2022 caused early fruit drop in the Indian River area, where two studies of 39,000 trees that might tolerate HLB are being conducted. Researchers now expect significant data from the studies will come after the 2023, 2024 and 2025 season harvests, but they have already gained some insights from the projects. The first experimental grove, …
During a historically low period of Florida citrus production, Inverness grower Chuck Bellamy has found a way to keep fruit on his trees. In the June cover story of Citrus Industry magazine, he tells what regenerative practices have reduced fruit drop in his grove. Not only is he keeping more oranges; he has lowered his production costs in the process. …
There has been much focus on the benefits of applications of plant growth regulators like gibberellic acid and 2,4-D, and more recently oxytetracycline hydrochloride to improve the health of citrus trees infected with HLB. Silicon also has been highlighted for its potential benefits to citrus. Mohammad Adnan Shahid, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, …
By Tom Spreen To proclaim that 2022 was a difficult year for the Florida citrus industry would be an understatement. In late January, a short freeze hit much of the commercial citrus-producing area with long-term implications. While its effect on the 2021–22 crop was small, it came as the 2022–23 bloom was about to begin after a warm December. It …
There is some buzz among citrus growers that new HLB therapies are beginning to show positive results in trees. But visual observations of trees are subjective and can vary from grove to grove and grower to grower. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has developed a new tool for growers that will provide a more …
The Citrus Research and Field Trial (CRAFT) Foundation received nearly 700 eligible applications — representing more than 42,000 acres — for its new Existing Tree Therapies Program. A random lottery drawing was recently conducted by a third party, and 159 projects have been selected for inclusion in the program. The remaining applications have been placed on a waitlist. CRAFT staff …
Brazil native Flavia Zambon will become assistant professor of production horticulture of citrus and other tree crops at the Indian River Research and Education Center (IRREC) in November. The IRREC, located in Fort Pierce, is a branch of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Zambon has had years of research experience in all of Florida’s …
This year’s Florida state budget, established by the Legislature in early May, is the largest in history at nearly $115 billion. Florida Citrus Mutual (FCM) reported that approximately $65 million was allocated to the citrus industry. FCM itemized what was allocated to the citrus industry prior to Gov. Ron DeSantis signing the budget: Additionally, the Department of Agriculture package bill …
Arnold Schumann, a professor of soil fertility and water quality with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), led the effort to study the effectiveness of citrus under protective screen (CUPS) in protecting trees from HLB. The work resulted in growers having confidence in the practice. Today, Florida CUPS plantings are closing in on 1,000 commercial …
The citrus session at the Florida Grower Citrus Show started off with a special award acknowledgement by Ron Cave, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC). Cave recognized Pasco Avery for his induction into the 2022 class of the IPM Hall of Fame from the Southern IPM …
During the recent Florida Citrus Growers’ Institute, Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, provided details on recently funded citrus research projects. “The $16.3 million (from the U.S. Department of Agriculture) will go toward new research or continuing research to keep promising projects going,” Rogers said. Eight …
By Amir Rezazadeh Among all the factors that will affect the productivity and profitability of a citrus grove, choosing the optimal tree spacing is crucial. Florida citrus growers are planting trees at significantly higher densities than in the past. Due to negative impacts on plant health following the emergence of huanglongbing (HLB or citrus greening) in Florida, canopy growth substantially …
The California Department of Food and Agriculture’s (CDFA) Asian citrus psyllid (ACP) quarantine program now requires all harvesters/farm labor contractors (FLCs) to have valid compliance agreements to harvest citrus groves. An FLC is defined as any person or establishment that employs people to perform work related to grove management and/or harvesting commercial citrus fruit. The requirement was announced by CDFA’s …
The Peace River Valley Citrus Growers Association (PRVCGA) hosted growers and industry members on National Orange Juice Day to discuss early experiences with trunk injection of oxytetracycline hydrochloride (OTC-HCl). Two new OTC-HCl products, ReMedium TI and Rectify, were registered this season for use as an HLB treatment in Florida citrus. While some growers are taking a wait-and-see approach to trunk …
