The November episode of the All In For Citrus podcast covers a multitude of grant-funded research that the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus team both leads and collaborates on. Citrus Research and Education Center Director Michael Rogers begins the podcast with a discussion on research projects UF/IFAS scientists are playing critical roles in collaborative …
Nov. 18-25 is National Farm-City Week, a time to recognize and honor the contributions of the country’s agriculturalists and to strengthen the bond between urban and rural citizens. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center (SWFREC) took the opportunity to recognize the agriculturists in its area. Some of its statements …
By Jawwad Qureshi Young citrus trees produce shoots with feather-stage leaves more frequently, making them highly attractive to the Asian citrus psyllid (ACP). This pest requires young shoots with feather-stage leaves to develop and reproduce. ACP is the pathogen’s primary vector responsible for causing huanglongbing (HLB) disease. Plant infection with HLB at an early age makes it challenging to bring …
In 2016, federal authorities began allowing Florida citrus growers to spray oxytetracycline solutions on their trees to combat citrus greening disease. Since then, researchers have been investigating oxytetracycline delivery methods. In a Citrus Expo presentation, Christopher Vincent, assistant professor of horticultural sciences at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, shared …
Larry Duncan provides updates on the damage done by sting nematodes and research into controlling them with nematicides and perennial peanut as a cover crop. Duncan is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) nematologist at the Citrus Research and Education Center. Sting nematodes have become a “real issue” for Florida growers in the past five …
By Arnold Schumann, Laura Waldo, Napoleon Mariner and Timothy Ebert According to the U.S. Department of Agriculture (USDA), Florida grapefruit production for the 2019–20 season was only 12 percent of the production recorded in 2003–04, prior to the arrival of huanglongbing (HLB) disease in the state. A major goal of the University of Florida Institute of Food and Agricultural Sciences …
Citrus growers should consider controlling HLB-spreading Asian citrus psyllids (ACP) only when a prescribed ACP population, or threshold, is reached. Entomologist Lukasz Stelinski suggested this approach in a virtual Citrus Expo presentation. Stelinski is a University of Florida Institute of Food and Agricultural Sciences researcher at the Citrus Research and Education Center in Lake Alfred. A summary slide Stelinski showed …
Michael Rogers discusses the importance of the recent sequencing of the trifoliate orange genome by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers and others. He also tells how growers can learn more about UF/IFAS research funded by the Florida Legislature. Rogers is director of the UF/IFAS Citrus Research and Education Center (CREC) in Lake Alfred and …
Citrus Research and Development Foundation (CRDF) directors recently received an update on planned rootstock field trials and discussed the organization’s budget, CRDF Chief Operating Officer Rick Dantzler reported. ROOTSTOCK TRIALSThe new rootstock trials will be overseen by CRDF’s Select Committee on Plant Improvement, which met on Oct. 22 with citrus grower John Gose as chairman. Dantzler said the field trials …
By Evan Johnson and Megan Dewdney The last two years have seen increasing grower questions and reports of citrus trunk disorders in Florida. Sometimes these reports are associated with sudden tree collapse. In many cases, phytophthora foot rot is initially suspected. Typically, the symptoms don’t quite match those of foot rot, and phytophthora cannot be isolated from the lesion. If …
As the new Florida citrus season starts, growers have many things on their minds: the low citrus forecast, the threat of potential freezes, and how best to protect both trees and employees. The November issue of Citrus Industry magazine aims to address these concerns. First up is a complete report on the U.S. Department of Agriculture’s initial crop forecast for …
An exciting development with genome sequencing, timely research in the face of COVID-19 and an update on sting nematode research headline October’s All In For Citrus podcast. Citrus Research and Education Center Director Michael Rogers details the benefits of recent news about the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) mapping the trifoliate orange genome. He says …
By Sarah Strauss, Antonio Castellano-Hinojosa, Davie Kadyampakeni, Ramdas Kanissery and Tara Wade Soil health is generally synonymous with soil quality and refers to the capacity of a soil to sustain biological productivity, maintain environmental quality and promote plant health. Soils are complicated ecosystems, and discussions of soil health must consider the links between soil functions and soil-based ecosystem services, such …
California’s ACP/HLB San Joaquin Valley Task Force reports that an increased number of Asian citrus psyllid (ACP) trap finds have occurred in the southern part of Kern County. The task force made the announcement in an open message to all citrus growers in the San Joaquin Valley. It was published on the Citrus Insider website on Oct. 16. Last month …
Pakistan entomologist Muhammad Arshad reported on work that opens the possibility of further studies to determine the potential of Cordia myxa as a trap crop to manage Asian citrus psyllid (ACP) and, ultimately, to reduce HLB disease. C. myxa, also known as Assyrian plum or lasura, is a broad-leaved deciduous fruit tree. In trap cropping, plants are used to attract …
Many Florida citrus growers have been using individual protective covers (IPCs) for several years primarily to protect trees from HLB-spreading Asian citrus psyllids (ACP). Smaller but increasing numbers of growers are utilizing the more expensive citrus under protective screen (CUPS) system to protect trees from ACP and HLB. Recently, Fernando Alferez informed growers in a virtual presentation about some other …
Including recent news about a peptide derived from finger limes, researchers have found many compounds over the last several years that could help growers manage or even fend off huanglongbing (HLB) disease. University of Florida Institute of Food and Agricultural Sciences Research Assistant Scientist Choaa El-Mohtar and his team have developed a new way to see how compounds can possibly …
Forty-nine growers and others participated in a self-guided, drive-through tour of the Millennium Block variety performance trial at the Indian River Research and Education Center (IRREC) on Oct. 9. “Several growers highlighted trees are off to a good start, and despite the fact they’re young, they could see clear differences,” said host and IRREC researcher Rhuanito “Johnny” Ferrarezi. Ferrarezi works …
In his virtual Citrus Expo presentation, Jude Grosser reviewed varieties and rootstocks showing promise for productivity in the face of HLB. Grosser is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant breeder. His presentation was based on work done by him and fellow UF/IFAS researchers Bill Castle and Fred Gmitter. Grosser said UF/IFAS released OLL-20 “based …
The old Parson Brown sweet orange variety is showing some characteristics that could make it more attractive than Hamlin, which has long been Florida’s leading early-season orange. “Observations made in commercial blocks in Polk and neighboring counties illustrate an improved canopy density, improved mature fruit retention and higher yields in the early-maturing Parson Brown sweet orange when compared to adjacent …
