By Lauren Diepenbrock Recently, several articles have highlighted a potential new threat to the citrus industry in Florida, the lime swallowtail. While it is true that this pest has been found in residential citrus plantings in Key West, it is unlikely that lime swallowtail will have much of an impact, if any, on Florida’s commercial citrus industry. Lime swallowtail is …
It’s almost April, and that means it’s almost time for the Florida Grower Citrus Show! The soon-to-be-released April issue of Citrus Industry magazine features an event guide to the new and improved Florida Grower Citrus Show. Included is a complete seminar schedule and list of participating exhibitors and sponsors for the April 13 event. Now under AgNet Media management, the …
The Florida Citrus Commission on March 15 heard an update on four sponsored projects under the New Varieties Development and Management Corp. (NVDMC). Peter Chaires, NVDMC executive director, provided the updates: 1. The primary effort of the U.S. Department of Agriculture Agricultural Research Service’s Citrus Scion Breeding Program is to select varieties throughout the 2022–23 season that have commercial potential. …
By Nian Wang How the huanglongbing (HLB) pathogen Candidatus Liberibacter asiaticus (CLas) causes damage to infected citrus trees has been widely debated. A recent study demonstrates that HLB is an immune-mediated plant disease (Ma et al., 2022). It was discovered that CLas infection of citrus stimulates systemic and chronic immune response in phloem tissues, including reactive oxygen species (ROS) production, …
Growers have been deploying several new therapies aimed at improving the health of HLB-infected citrus in recent years. Plant growth regulators like gibberellic acid, 2,4-D and brassinosteroids have demonstrated the ability to improve tree health and help in fruit retention. More recently, direct delivery of oxytetracycline hydrochloride (OTC-HCl) via trunk injection has been approved for use in groves. There is …
Plant pathologist Megan Dewdney put emphasis on new plantings during a mid-March discussion of phytophthora management for citrus trees infected with HLB. Dewdney is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor at the Citrus Research and Education Center, where she spoke. Dewdney’s presentation was part of an OJ break hosted by UF/IFAS Extension multi-county …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP Overnight success comes after years of hard work. In science, that means the “eureka” moment isn’t a moment at all. It comes after years of research that can cost millions of dollars. That’s a level of resources that the federal government helps deliver. We’re fortunate that the U.S. Department of Agriculture’s National Institute of …
The short timeframe for satsuma mandarins to be harvested and sold in the fall created a bottleneck of supply around the Thanksgiving holiday in 2022. An excess supply led to a challenge for growers attempting to sell their fruit when demand diminished, according to Kim Jones, who grows and packs citrus in Florida and Georgia. “The week of Thanksgiving when …
By Davie Kadyampakeni, Samuel Kwakye, Hossein Ghoveisi, Lauren Diepenbrock and Jawwad Qureshi Deficit irrigation practices can reduce water and energy costs, thus potentially increasing water-use efficiency and water savings in citrus production. Irrigation management through deficit applications, if timed at periods of reduced water demand, could help trigger increased root water and nutrient uptake while synchronizing citrus flush patterns. These …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) multi-county citrus Extension agent Ajia Paolillo recently provided information about two commercial oxytetracycline hydrochloride products approved for use against HLB. TJ Biotech LLC was the first company to receive approval from the Environmental Protection Agency (EPA) for trunk injection of this formulation. EPA granted TJ Biotech a Federal Insecticide, Fungicide, …
After HLB disease was first found in Florida in 2005, many people were discouraged from growing citrus in their home landscapes. There were no citrus recommendations tailored for home gardeners in the HLB era. Now, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has responded to home gardeners who want to plant citrus trees again. Researchers are …
By Tripti Vashisth and Taylor Livingston Grower-led trials in 2022 showed positive results of gibberellic acid (GA) treatment on Hamlin trees in Florida. This article primarily discusses two growers’ trials in detail. Both sites showed improvement in fruit production from the GA application. Many growers have adopted GA applications in the past year as part of their grove management strategy. …
Allowing citrus hybrids with certain criteria in orange juice (OJ) was one of several issues addressed in a recent workshop about potential changes to OJ’s standard of identity. Peter Chaires, executive director of the New Varieties Development and Management Corp., discussed benefits of increasing the hybrid allowance in OJ. Chaires presented a consumer study of juices conducted by University of …
By Julio Cruz, João-Pedro Ferreira and Christa Court Many Florida citrus growers are under stress due to disease and extreme weather events. Citrus growers often request financial or other types of support from local, state and federal governments due to such situations. Understanding and communicating how the citrus industry supports economic activity throughout the state, even outside of the industry …
In their fourth such clinic, faculty from the University of Florida will test farmworkers for chronic diseases from 8 a.m. to 2 p.m. on March 23 in Arcadia. The University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) and College of Medicine will conduct the clinic. The screenings will be at the Turner Agri-Civic Center, 2250 NE Roan Street. …
How much life lives in a tiny bit of soil? A lot, according to Sarah Strauss, assistant professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). “The estimate I often mention is there can be over a billion microorganisms in a gram of soil, which is about this size of a quarter,” she said during the …
The event’s fresh format will pack plenty of education and fellowship in a single day. The Florida Grower Citrus Show, scheduled for April 13, is fast approaching. The event opens at 7:30 a.m., and breakfast will be served at 8:00 a.m. Growers and industry stakeholders are invited to sign up for complimentary preregistration. NEW LOOK AND LOCATION This year, the …
Cold-hardy citrus growers need to protect their trees against the citrus leafminer this year, more so than ever. A lack of control could have negative consequences for trees still recovering from the Christmas freeze last December. Xavier Martini, assistant professor of entomology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center, …
Researchers will assess 20 to 30 Florida citrus groves impacted by 2022’s Hurricane Ian to learn lessons that will help growers in the future. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers Christopher Vincent and Tripti Vashisth and their teams will conduct the assessment. The research will be funded by a $280,000, one-year grant from the U.S. …
The objective of a new study published in HortScience was to evaluate and understand the nutrient uptake potential of citrus rootstocks. Conducted by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers, it is one of the first citrus studies to report nutrient uptake efficiency and the potential of rootstocks. The information presented in the study can be …
