Six Fundecitrus researchers recently received an award from the journal Tropical Plant Pathology, edited by the Brazilian Society of Phytopathology. The award is in recognition of the researchers’ work in the scientific article “Overview of citrus huanglongbing spread and management strategies in Brazil.” The researchers honored are Renato Beozzo Bassanezi, Sílvio Aparecido Lopes, Marcelo Pedreira de Miranda, Nelson Arno Wulff, …
By Megan Dewdney To make informed management decisions, growers need to know about and understand the findings from huanglongbing (HLB) research that are currently available. However, the delivery of research results to growers is often fragmented, and results can be difficult to find. Furthermore, what information and conclusions are available to growers from projects or scientific journals can be highly …
Developing disease-resistant, high-quality improved crop varieties may seem like a “hairy” task, but Texas A&M AgriLife Research scientists may have gotten to the root of the issue. A new biological technology that develops and multiplies disease-resistant citrus plants is under development by an AgriLife Research team led by Kranthi Mandadi. Mandadi is an associate professor at the Texas A&M AgriLife Research …
The Citrus Research and Development Foundation (CRDF) board of directors meeting in July focused largely on the use of oxytetracycline (OTC) as an HLB treatment in citrus. The board considered projects testing it in combination with other antimicrobial compounds or as a standalone treatment. Trunk injection of OTC has given the Florida citrus industry hope that it might be a …
The U.S. Department of Agriculture National Institute of Food and Agriculture (USDA NIFA) provides research directed at overcoming the devastating HLB disease and protecting the nation’s citrus industry. Since 2014, NIFA has funded approximately $200 million for HLB research projects. Many HLB-related NIFA project one-page summaries are now easily accessible and written in a grower-friendly language and format on the …
In a virtual seminar for growers on July 19, Davie Kadyampakeni reinforced that optimal, balanced nutrition and frequent irrigation can improve HLB-affected citrus trees, yield and fruit. Kadyampakeni is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor at the Citrus Research and Education Center in Lake Alfred. NUTRITION“Citrus fruit yields, juice quality and canopy size …
While it remains to be seen if trunk injection of oxytetracycline hydrochloride (OTC-HCl) is a game changer in the fight against HLB, it certainly has intensified the conversation about the potential for antimicrobial treatments. There are literally hundreds of materials that might be effective at reducing the HLB bacteria in trees, but it has been a slow process to screen …
Citrus is grown in many different regions across the globe. Some of those places look very different than the Florida landscape. But that doesn’t mean growers in different regions can’t benefit from learning about how others grow their fruit. That was the message from Christoper Vincent, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor of environmental …
By Davie Kadyampakeni Nutrients are needed for optimal tree growth, fruit yields and juice quality. Any nutrient deficiencies could result in low yields and decreased revenue, so it is essential to make sure citrus trees receive adequate nutrient supplies at all times. Micronutrients, though required in minute quantities, are especially important for citrus trees impacted by citrus greening. Examples of …
By Choaa A. El Mohtar Projected citrus production in Florida for the 2022–23 season is less than 20 million boxes. This is more than a 90% decrease compared to the 2003–04 season, which was around 292 million boxes. The main reason for the decrease is huanglongbing (HLB) disease. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus …
Scott Angle, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) senior vice president for agriculture and natural resources, began the educational session during the Florida Citrus Industry Annual Conference with a message of urgency. He recognized the critical threat posed by HLB and said science could catch up to the problem. “Plant sciences are advancing globally at almost …
By Taylor Livingston and Tripti Vashisth Fighting HLB alongside weather disasters like freezes and hurricanes is leaving growers with little options for sustaining yields. The Hamlin sweet orange variety is known for higher susceptibility to HLB symptoms which cause rapid tree decline, including increased pre-harvest fruit drop and canopy loss. Production strategies that target fruit drop and canopy health improvement …
Fundecitrus researcher Marcelo Pedreira de Miranda has received the Outstanding Citriculture Engineer-Agronomist Award from the 48th Expocitrus and 44th Citriculture Week. The Brazilian entomologist, whose main studies are related to HLB, has worked at Fundecitrus since 2008. The award ceremony where Miranda was honored was part of the opening afternoon of the exhibition week and was attended by authorities and …
Entomologist Kirsten Pelz-Stelinski recently shared findings from trials on the use of foliar-applied and trunk-injected antibiotics for controlling HLB and the Asian citrus psyllids (ACP) that spread the disease. Pelz-Stelinski is associate center director at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) in Lake Alfred. In a May 17 presentation …
The damage that HLB has inflicted on Florida citrus groves and production over the past 18 years should serve as a warning for California producers, California’s Citrus Pest & Disease Prevention Program (CPDPP) stated recently. CPDPP noted that with HLB detected in thousands of California residential trees, it’s important for commercial growers to take steps to prevent the disease. According …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP The hurricane-battered harvest numbers don’t show it, but we’re in a much better place in developing scientific solutions for managing HLB than we were a year ago. That’s because our scientists have discovered that tools invented to solve other problems can help address your one big problem. GIBBERELLIC ACIDFor example, gibberellic acid (GA) has …
Brazil’s Fundecitrus in 2022 and 2023 conducted an awareness campaign to replace citrus and myrtle plants to combat HLB in the municipality of Itobi, São Paulo. The citrus and myrtle plants were replaced with other fruit and ornamental species that do not host the Asian citrus psyllid that transmits HLB, also known as greening disease. These citrus and myrtle plants …
A comprehensive map of the genome of an Australian native lime species that is resistant to HLB could be the key to preventing the disease from entering Australia. Researchers from The University of Queensland (UQ) in Australia have sequenced the genome of the Australian round lime, also known as the Gympie lime. They are now looking at five other native …
Canadian college Seneca, in partnership with Ottawa-based Evik Diagnostic Innovations Inc., is working to develop a quick diagnostic test for the citrus disease HLB. Frank Merante, professor in Seneca’s School of Biological Sciences & Applied Chemistry, is the principal investigator for the project. The idea behind the research was to develop a simple way for growers to test crops and identify the …
The Florida Citrus Commission (FCC) in March heard updates on programs intended to provide growers with HLB-tolerant or -resistant trees and on other Florida Department of Citrus (FDOC) scientific research programs. Director of Scientific Research Rosa Walsh provided the updates. The FCC serves as the FDOC’s governing board. Walsh announced that for the FDOC’s Program for Expedited Propagation, all materials …
