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 …
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 …
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 …
A combination of gibberellic acid (GA) and 2,4-D reduced preharvest fruit drop by 18% and improved fruit size but produced no statistical effect on yield, researcher Tripti Vashisth reported Aug. 30. The combination “seems promising,” the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) horticulturist stated. The report was based on first year results from a trial of …

This year’s event will be held Tuesday, April 5 from 8:30 …
Recent research describes in detail how HLB causes damage to citrus trees and presents the case that HLB is a pathogen-triggered immune disease. A pathogen-triggered immune disease results from the activation of an organism’s immune cells fighting a pathogen. Nian Wang, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor, took part in the research. This is the …
Rick Dantzler, chief operating officer of the Citrus Research and Development Foundation (CRDF), gave an update at the recent Florida Citrus Show on the latest efforts to find solutions to the HLB problem.

The Citrus Research and Development Foundation (CRDF) governing board on Jan. 25 approved a project aimed at reducing fruit drop by using potassium, zinc, gibberellic acid and the herbicide 2,4-D in different timing scenarios. The funding will allow University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher Fernando Alferez to finish two years of work that CRDF Chief …
By Michael Rogers January marks the season for resolutions: exercising more, eating well and being more organized. But in the research world, resolutions may not be that simple. I don’t think that University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers could be any more “resolved” in finding ways to fight citrus diseases and ways to improve how …
By Frank Giles The U.S. Department of Agriculture (USDA) reported a drop in estimated Florida orange production in its December crop update.
