The August episode of the All In For Citrus podcast takes listeners on a deep dive into the use of plant growth regulators like gibberellic acid (GA) to help fight fruit drop. The episode features an in-depth conversation between Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, and …
Fresh citrus growers, packers and shippers will meet for Citrus Packinghouse Day on Aug. 25 at the Citrus Research and Education Center’s (CREC) Ben Hill Griffin Hall in Lake Alfred, Florida. They will hear the most current information about food safety, worker visa options and other topics related to fresh fruit handling and transport. The free event will include exhibitors …
The Florida Department of Agriculture and Consumer Services (FDACS) named Madeline Mellinger the 2022 Woman of the Year in Agriculture. Mellinger founded Glades Crop Care, Inc. in 1972 and is still the company’s chief operating officer. Glades Crop Care provides integrated pest management and crop counseling services to more than 65,000 acres of plants and more than 60 varieties of fresh …
By Sandra M. Guzmán In Florida citrus, black fabric mulch groundcovers have been used for the control of the invasive Diaprepes abbreviatus (root weevil). However, these groundcovers can also serve as a best management practice (BMP) to optimize tree water uptake and maintain nutrients around the root system. A three-year University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) …
By Yiannis Ampatzidis and Sandra M. Guzmán Pests and diseases, nutrient deficiencies, tree stress from environmental conditions and other factors can be overwhelming. The arrival of sensors and small unmanned aerial vehicles (UAVs) make it possible to gather large amounts of data to assess risk factors and estimate possible crop performance scenarios based on the availability of resources. At the …
Hot temperatures and dry conditions in some parts of the Southeast add up to ideal conditions for mite populations to increase in citrus groves. Lauren Diepenbrock, University of Florida Institute of Food and Agricultural Sciences assistant professor and entomologist, said citrus can tolerate some spider mite pressure. Increased pressure, though, can leave an impact. “You can handle some amount of …
Some species of snails in Florida groves, normally seen on irrigation emitters and tree trunks, have recently “taken up residency in young citrus trees,” University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension agents Chris Oswalt and Ajia Paolillo reported. Here’s a summary of what the agents wrote in a recent UF/IFAS Central Florida citrus Extension newsletter: Once …
By Manjul Dutt The finger lime is an HLB-tolerant Australian native citrus that has been gaining popularity and importance in the last few years. Finger lime has several unique fruit qualities that set it apart from conventional sweet oranges and mandarins. The primary characteristic of this fruit is the round to teardrop-shaped juice vesicles, known as “citrus caviar,” that burst …
By Bryony C. Bonning and Lukasz L. Stelinski Asian citrus psyllids (ACP) transfer the pathogen that causes citrus greening from plant to plant as they feed. After confirmation of citrus greening in Florida in 2005, growers intensified their use of insecticides against ACP to try to stop disease spread. However, this method alone has yielded variable success and increased costs. …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) specialists are alerting Georgia citrus growers about an invasive pest that’s impacting Florida’s crop. Lebbeck mealybugs have yet to navigate their way to Georgia. But it is only a matter of time, says Lauren Diepenbrock, UF/IFAS assistant professor and entomologist. “It’ll get up to Georgia probably. We’re doing our best …
In the quest for better fruit retention in HLB-infected citrus, there has been a good deal of attention placed on the use of plant growth regulators to fight fruit drop. Gibberellic acid (GA) has been the focus of new research in recent years to establish refined timing of applications to optimize results in Florida citrus. Much of that research has …
By Michael Rogers As we approach a new citrus-growing season, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers and Extension agents working throughout the state renew their focus on finding solutions that growers can use in the short term to sustain their operations. While we value our longer-term research projects, efforts that provide tangible applications that …
On Aug. 4, Colorado State University (CSU) decreased its hurricane forecast for Atlantic seasonal activity and landfall strike probability for 2022. But citrus growers and other agriculturists shouldn’t relax their guard because the CSU Department of Atmospheric Science continues to call for an above-average Atlantic hurricane season. NEW PROJECTIONSCSU now forecasts the Atlantic will have 18 named storms in 2022, …
By Amir Rezazadeh Saline soil and water damage many citrus groves in Florida. In general, when the dissolved salt concentration in soil or water increases, it is referred to as “saline” soil or water. But how much increase in salt concentration makes soil or water saline? Citrus plants’ major reactions to excessive salt in the soil or water are reduced …
By Tripti Vashisth and Mary Sutton Citrus trees affected by huanglongbing (HLB) consistently have small fruit and low fruit numbers at harvest. The low fruit numbers are largely attributed to the increased rates of preharvest fruit drop that accompany HLB. Small fruit is more likely to drop during this preharvest period, suggesting a link between fruit size and retention. To …
Brazil, China and Mexico are the top producers. Brazil easily continues to lead the world in orange and orange juice (OJ) production, while China dominates in production of tangerines/mandarins and grapefruit. Mexico remains the leading producer of lemons and limes. These facts come from a July report on world citrus issued by the U.S. Department of Agriculture’s Foreign Agricultural Service. …
Plant physiologist Ute Albrecht recently gave a presentation on increased fruit yield and other apparent benefits of injecting the antibiotic oxytetracycline into citrus tree trunks. The University of Florida Institute of Food and Agricultural Sciences researcher also discussed other advantages that trunk injection provides. These advantages include: Precise delivery of materials Elimination of spray drift Reduced risk for worker exposure …
By Jamie Burrow and Ruth Borger Over the last several months, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus team has been preparing for the annual Citrus & Specialty Crop Expo. The excitement is in the air as many faculty are preparing seminar presentations on valuable information that growers may use today to support their operations. …
Two University of Florida (UF) startup companies have formed a union to help reverse the trend of declining Florida citrus production. Agriculture Intelligence and Satlantis believe they can offer a powerful tool to help the state’s growers more closely monitor their trees and manage problems faster. The startups, housed in one of UF’s business incubators, will combine expertise in precision …
The Citrus & Specialty Crop Expo is set for Aug. 17–18 in North Fort Myers, Florida. The event, held at the Lee Civic Center, will be a flurry of activity as citrus and specialty crop growers come together to learn, network and see the latest tools of the trade in farming. The latest episode of the All In For Citrus …
