A wealth of observations are being recorded by growers and scientists on the effects of trunk injection of oxytetracycline (OTC). Visually, trees have responded with better canopies. Hopefully, higher yields and quality will continue to follow the applications. But what about below ground? There have been recorded improvements in citrus root mass in treated trees. Sarah Strauss, associate professor of …
The Southeastern Coastal Center for Agricultural Health and Safety (SCCAHS) and the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) have created an online toolkit to help protect agricultural workers from the summer heat. Last year’s sweltering summer temperatures convinced SCCAHS leadership that additional promotion about heat-related illness education could save lives. Even before the summer ended, the …
Sarah Strauss, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) soil microbiologist, joined the June All In For Citrus podcast episode to discuss her research on the interaction of oxytetracycline (OTC) currently being injected into citrus trees and the soil microbiome. She noted that OTC does change the soil microbial community. The good news is that the changes …
By Jawwad Qureshi The Asian citrus psyllid (ACP, Figure 1) is the vector of huanglongbing (HLB) disease associated with the phloem-limited bacterium Candidatus Liberibacter asiaticus. Infected trees start to decline and produce poor-quality fruit, which drops prematurely. Consequently, citrus production has decreased dramatically since the advent of HLB in Florida in 2005. There is no cure for the disease yet. …
A recent update of Millennium Block research at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center in Fort Pierce indicates the 5,500 trees in the project are yielding promising results. The four trials within the Millennium Block aim to unlock the genetic potential of new scion and rootstock hybrids never tested …
In the fall of 2022, five University of Florida researchers investigated Florida residents’ attitudes on HLB and Asian citrus psyllids (ACP) using online surveys over a 9-month period. The results of the study, Residents’ contribution to Asian citrus psyllid and citrus greening management in Florida residential habitats, was recently published in the Journal of Integrated Pest Management. Authors Romain Exilien, …
The conversation in Florida citrus continues to center around trunk injection of oxytetracycline (OTC). The July issue of Citrus Industry magazine presents the latest information on the OTC topic. OTC product labels require a one-year pause in application after two years of use. This requirement was put in place to prevent pathogen resistance to the product. Florida growers who have …
The educational seminars at the June Florida Citrus Industry Annual Conference covered a wide range of topics intended to give growers hope that progress is being made in the fight against HLB. During the June All In For Citrus podcast, Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, …
By Davie Kadyampakeni and Miurel Brewer Row middle management is a key area that can improve tree performance. Row middles encompass 80% of citrus orchards, and 70% of the root system of citrus trees was located in row middles before huanglongbing (HLB). Typically, Florida citrus growers manage row middles using physical, chemical and mowing practices, often leaving them free of …
Alissa Hevesh on June 17 became the new Highlands County agriculture production/natural resources Extension agent. The University of Florida Institute of Food and Agricultural Sciences position includes citrus agent duties. Hevesh received a dual bachelor’s degree in economics and environmental studies and a minor in leadership studies from Eckerd College in 2018. She received a master’s degree in food and …
Florida citrus growers gathered in rainy Bonita Springs last week for the Florida Citrus Industry Annual Conference. The event hosted by Florida Citrus Mutual drew a good crowd, who were happy to see the heavy rains brought by a no-name tropical system that helped break the drought in some areas of the state. The mood of growers was mixed. While …
The pros of using interstocks for HLB management seemed to outweigh the cons, based on a presentation horticulturist Manjul Dutt made at this spring’s Florida Citrus Growers’ Institute. Dutt is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor. An interstock is a graft of a citrus selection that can be used as a bridge between …
By Rob Gilbert, ragilber@ufl.edu, @IFAS_VP Let’s start with the most important thing. Citrus science remains a top priority of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Citrus is special. My goal for citrus is sustainability. That means profitability. Here are a few new ways UF/IFAS has demonstrated its support for citrus science during the past five …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) weed scientist Ramdas Kanissery offered numerous tips and observations for improving herbicide efficiency at this spring’s Florida Citrus Growers’ Institute. They included: In addition to discussing herbicides, Kanissery reported that cover cropping, an emergent practice in Florida citrus production, may contribute to longer-term weed management in row middles.

Back in the early days of the HLB fight, it was observed that what is going on underground in citrus tree root systems is just as important as what is happening aboveground. In 2013, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and U.S. Department of Agriculture-Agricultural Research Service researchers published that 27% to 40% root loss due …
Orange peels may hold a key to better cardiovascular health, new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS)-led research shows. Some gut bacteria help develop cardiovascular disease. When they feed on certain nutrients during digestion, gut bacteria produce trimethylamine N-oxide (TMAO). Levels of TMAO can help predict future cardiovascular disease, according to researchers at the Cleveland Clinic. …
By Jawwad Qureshi The Asian citrus psyllid (ACP, Figure 1) continues to feed on citrus trees infected with citrus greening and spread the disease to newly planted young trees. Therefore, it is not possible to produce a healthy citrus tree in an environment where citrus greening is endemic. Only the citrus under protective screen (CUPS, Figure 2) system allows the …
According to Rick Dantzler, Citrus Research and Development Foundation (CRDF) chief operating officer, the past seven days have been busy for CRDF’s committees. First, the Plant Improvement Committee, chaired by grower Joby Sherrod, reviewed several projects and ideas seeking HLB resistance in detail. A three-year plan for the plant improvement programs for University of Florida Institute of Food and Agricultural …
By Amir Rezazadeh Citrus fruit splitting is an important problem for growers, causing frustration and economic losses. This phenomenon occurs when the rinds of citrus fruits crack open, exposing the inner pulp. Understanding the reasons behind citrus fruit splitting is crucial for growers to implement effective preventive measures. IRRIGATION PRACTICES Inconsistent watering regimes, particularly irregular watering followed by heavy irrigation, …
Chilli thrips (Scirtothrips dorsalis) has been documented in Florida since 1991. This pest has a history of impacting ornamentals, some vegetables, grapes and berry crops. Most recently, chilli thrips has affected citrus, but only in nurseries and in citrus under protective screens (CUPS). Feeding damage includes death of young flush (Figure 1), leaf damage on expanded flush that results in …
