Growers have largely adopted new trunk-injection therapies to fight the effects of HLB in citrus groves. In addition, plant growth regulators have helped improve tree health and fruit retention. One University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientist reminds growers to maintain their fertilizer programs as the new therapies are deployed. Davie Kadyampakeni, UF/IFAS associate professor of …
By Matt Smith Editor’s note: This article grants one continuing education unit (CEU) in the Core category toward the renewal of a Florida Department of Agriculture and Consumer Services restricted-use pesticide license when the accompanying test is submitted and approved. This article is an updated version of a previous article, “Scouting: The Tip of the IPM Spear,” published in the …
The February issue of Citrus Industry magazine takes a look at efforts to combat HLB. Some strategies are already available for growers to implement in their groves, while others offer hope for long-term solutions. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recently launched a new Crop Transformation Center. The goal of the center is to use …
Seventy-five U.S. House of Representatives members have asked House and Senate appropriations leaders for an H-2A visa guestworker wage freeze in an upcoming spending package. The text of the representatives’ letter to appropriations leaders follows: “We write with shared concerns regarding the annual adjustment to the Adverse Effect Wage Rate (AEWR). Now in 2024, the H-2A labor rates paid by …
Matthew Machata grew up in Polk County on the family’s citrus farm, Rolling Meadows Ranch Groves in Lake Wales, Florida. After he graduated high school, he joined the Marine Corps and served two tours in Iraq. He then attended Auburn University, where he earned a degree in aerospace engineering. At the time, his plans didn’t include farming, but that changed …
Australian fresh orange production is forecast at 530,000 metric tons (MT) in 2023–24 by the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA FAS). This is a 5% increase over 2022–23 production of 505,000 MT. Producers expect to benefit from easing input costs and labor constraints in 2023–24. In particular, the costs of fertilizer and crop protection chemicals have reduced …
By Tripti Vashisth, Taylor Livingston and Jamie Burrow Canopy density is one of the most effective measurements to assess tree health of HLB-affected trees. Canopy density accurately distinguished between high and low fruit-producing trees in field trials, whereas CLas Ct value has been found to not be correlated with fruit yield. Many new tools such as nutrient management guidelines, plant …
By Sandra M. Guzmán Efficient irrigation management is crucial in optimizing tree growth and promoting sustainable management practices in modern agriculture. This article introduces IrrigMonitor, an Internet of Things data visualization platform developed at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC) Smart Irrigation and Hydrology Lab. IrrigMonitor is a …
Alico Citrus, a division of Alico, Inc., harvested less than half its citrus in the fiscal year ending Sept. 30, 2023 as it did in the prior year. The decline was largely the result of impacts from Hurricane Ian in September 2022. Alico has approximately 49,000 citrus acres in seven Florida counties. The company reported on Dec. 6 that it …
By Davie Kadyampakeni, Lorenzo Rossi and Alan Wright Huanglongbing (HLB) disease lowers tree performance by reducing water and nutrient uptake as a result of root loss. HLB-affected trees have a fibrous root loss of about 30% to 80%, which increases as disease symptoms develop in the canopy. Investigating optimal nutrient concentrations in citrus roots thus improves the understanding of HLB …
By Davie Kadyampakeni and Megan Dewdney The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) conducted a six-year project to determine if plant nutritional fertilizer sources coupled with specific crop protection chemicals help mitigate citrus diseases. This project was conducted on a 5-acre commercial citrus grove block near the Citrus Research and Education Center (CREC) in Lake Alfred. …
By Frank Giles and Tacy Callies The Citrus & Specialty Crop Expo hosted two citrus educational sessions during the Aug. 16–17 event held at the Florida State Fairgrounds in Tampa. The sessions included both long-term research aimed at delivering trees resistant to HLB as well as what growers can do today to help mitigate the effects of the disease in …
By Tacy Callies Before they were married, Nate and Anna Jameson vowed they would one day farm for themselves. They met while attending the University of Florida. Nate graduated with a Bachelor of Science in ag operations management, while Anna earned her degree in animal science. After graduation, Anna worked for Lykes Meat Group and Nate for Ben Hill Griffin …
Fresh lemon production in Argentina in 2022–23 is forecast to decline to 1.65 million metric tons (MMT), down from 2.1 MMT the prior year, the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) reported recently. The decline is due to the impact of rising costs, which have prompted smaller producers to limit the maintenance needed on lemon-bearing trees and …
By Jawwad Qureshi, Lauren Diepenbrock and Davie Kadyampakeni Protecting citrus trees from the Asian citrus psyllid (ACP) is critical to reducing the spread and severity of huanglongbing (HLB) or citrus greening disease. ACP, the vector of the pathogen responsible for causing HLB in citrus, needs young shoots to develop and reproduce. The frequent availability of viable shoots in young trees …
Alico, Inc. began treating citrus trees in January 2023 with an oxytetracycline (OTC) product via trunk injection as a citrus greening therapy. “Through June 30, 2023, we have treated over 35% of our trees with OTC, which is expected to mitigate some of the impacts of citrus greening and is expected to decrease the rate of fruit drop, as well …
The 2023–2024 Citrus Production Guide will be available to growers at the Citrus & Specialty Crop Expo in Tampa on Aug. 16–17. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) publication includes the latest technical advice on HLB management, tree nutrition, grove management and other aspects of Florida citrus cultivation. The guide is a comprehensive reference meant …
A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher recently wrote an article about silicon that included recommendations for its use. The article by Muhmmad Shahid, assistant professor of horticulture, appeared in the UF/IFAS Cold Hardy Citrus Connection newsletter. Silicon’s benefits may include improved yield, a strengthened root system and tolerance to abiotic stress, including cold. Excerpts …
By Michael Rogers The 2022–23 Florida harvest season is now behind us. Yield losses magnified by the weather events this past season position the next couple of years as “make or break” for many growers. The lingering effects of hurricane Ian will impact next season’s crop as trees continue to recover and balance out canopy regrowth with fruit production. Despite …
