Researcher Tripti Vashisth has been telling citrus growers about the benefits of using gibberellic acid (GA) on citrus trees. At the Citrus & Specialty Crop Expo, the University of Florida Institute of Food and Agricultural Sciences horticulturist said GA continues to show efficacy, based on 2022 harvest numbers. Vashisth’s Expo presentation included details from a 2016–2022 study of 10-year-old Valencia …
By Tripti Vashisth Hurricane Ian caused extensive destruction on the Florida coast and inland, in both urban and rural areas. The state’s citrus groves had to sustain hurricane-speed winds and flooding. HLB-affected trees undergo a lot a stress, and now the hurricane has added more abiotic stress to trees. High-speed winds caused significant fruit drop and leaf drop. The goal …
By Ariel Singerman During the 2021–22 citrus season, the Risk Management Agency (RMA) started offering a new option to Florida citrus growers for insuring their crop. The policy is called Actual Production History (APH) and provides coverage for yield losses based on a farm’s historical records. While the Whole Farm Revenue Protection (WFRP) policy also uses farm records as a …
“Hurricane Ian has devastated much of Florida’s citrus industry,” said Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center. “The harsh reality is that the 2022–2023 season will be one of the most challenging that any of us has faced.” Several UF/IFAS Extension agents made early assessments of the …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) faculty recommend actions citrus growers can take to prevent further damage to root systems and future fruit drop following Hurricane Ian. DEAL WITH PHYTOPHTHORAIf standing water has occurred in groves with phytophthora problems, growers should evaluate for root damage and treat accordingly. Floodwaters resulting from heavy rains can severely impact …
Borates Today recently issued a news release titled Citrus Fruits and Boron: What You Need to Know. A summary follows: Boron is a trace element used in the production of citrus fruits. It is required for proper plant development and preserving consistent fruit yield and quality. The element has a role in flower initiation, pollen germination, nitrogen metabolism, hormonal influences …
The severe impacts of recent storms are layered on top of the complex set of challenges already facing U.S. citrus growers—especially in Florida. From high input costs to domestic supply shortages, the unmatched devastation caused by citrus greening disease, and now the recovery efforts needed post-hurricane, growers need holistic solutions–and they need them fast. The good news is that breakthrough …
The average incidence of HLB rose from 22.37% in 2021 to 24.42% in 2022 in Brazil’s citrus belt, an annual survey by Fundecitrus shows. That’s an increase of 9.16%. In the regions of Brotas, Limeira and Porto Ferreira, where the incidence was already high in previous years, HLB increased to even more worrying levels of 49.41%, 70.72% and 74.05%, respectively. …
As the 2022–2023 harvest season kicks off, Glenn Beck of Beck Bros. Citrus is hopeful for a better season than last year. He has witnessed the groves he owns and manages suffer the effects of HLB over the years. When it comes to managing the disease, Beck has a simple philosophy: Stick with a solid production plan. He acknowledges that …
Multi-county citrus Extension agent Ajia Paolillo discussed the role of plant growth regulators (PGRs) in groves in a recent Extension newsletter. She cited University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) horticulturists Tripti Vashisth and Fernando Alferez as sources. Here’s a summary of Paolillo’s article: GIBBERELLIC ACIDGibberellic acid (GA) is one of the PGRs used in citrus. It …
An orange forecast update for Brazil’s São Paulo and West-Southwest Minas Gerais citrus belt is for 314.09 million boxes, a decrease of 2.86 million boxes or 0.9% from the original May forecast. The update was issued by Fundecitrus. All of the decrease is in the early-season orange varieties. The forecast for Hamlin, Westin and Rubi oranges is now 57.1 million …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has appointed internationally acclaimed entomologist and ecologist Matthew Thomas as director of the new Invasion Science Research Initiative (ISRI). Thomas will establish the framework for ISRI, which will bring together more than 120 UF/IFAS scientists from more than 20 departments currently dedicated to the detection, diversion, tracking and control …
By Christa Court Disaster events, such as extreme weather events (hurricanes, floods, droughts, etc.), have always been and will continue to be a threat for growers. Impacts to a citrus grove might include production losses associated with fruit drop from surviving trees and asset damages to buildings, machinery/equipment, irrigation systems and destroyed trees. Producers might also incur increased costs for …
Tripti Vashisth, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of horticultural sciences, has dedicated several years of research into the use of plant growth regulators like gibberellic acid (GA) to fight fruit drop in citrus. In the August All In For Citrus Podcast, Michael Rogers, director of the UF/IFAS Citrus Research and Education Center, interviewed …
SUMMARY: Many Florida citrus growers have made the decision to shift their focus away from saving older HLB-infected trees and toward protecting and strengthening young citrus trees, using soil probiotics, before too much damage is done. Understanding citrus trees’ vascular systemsCitrus trees have developed a complex but effective circulatory system for the uptake, storage, and utilization of water and nutrients. …
Entomologist Lauren Diepenbrock discussed control of three pests — lebbeck mealybug, Bulimulus sporadicus snails and diaprepes root weevils — at the recent Citrus & Specialty Crop Expo. The University of Florida Institute of Food and Agricultural Sciences researcher described the mealybug and snails as “new pest challenges” and diaprepes as the resurgence of an old pest. LEBBECK MEALYBUGLebbeck mealybug was …
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.
