By Fernando Alferez and Divya Aryal Brassinosteroids (BRs) are a class of plant growth regulators with several effects on plant growth and development. They engage in crosstalk with other hormones like auxin, gibberellins, ethylene and abscisic acid, influencing all plant growth and development aspects including fruit maturation, but the timing of this effect appears to be short and tightly regulated. …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers recently explained the benefits of raised bed planting and mulching to improve citrus tree establishment, productivity and resilience against environmental stress. Assistant Professor Muhmmad Shahid and Postdoc Scholar Shahid Iqbal, both of the North Florida Research and Education Center, and Associate Professor Davie Kadyampakeni of the Citrus Research and …
By Mongi Zekri Editor’s note: This article grants one continuing education unit (CEU) in the Core category toward the renewal of a Florida Department of Agriculture and Consumer Services restricted-use pesticide license when the accompanying test is submitted and approved. A minimum score of 70% is required to receive credit. Pesticides should not be considered the first line of defense against …
Citrus under protective screen (CUPS) continues to grow in popularity with about 1,500 acres now planted in Florida. The October All In For Citrus podcast covers CUPS and some of the challenges growers can face with the system. Jerry Mixon, a CUPS grower, discusses why he wanted to try the system and some of the challenges he has faced with …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC) will host its annual Millennium Block Field Day Nov. 6 from 9 a.m. to noon. The field day will showcase the center’s emphasis on research to find a solution to citrus greening disease. The IRREC is located at 2199 South Rock Road …
Coming soon in the November issue of Specialty Crop Grower magazine are several articles geared to citrus growers. The Citrus Industry section of the magazine addresses a range of topics, including irrigation and nutrient management, CRISPR breeding efforts, momentum and research projects for the Florida 2025–26 citrus season and more. One of the best ways to keep HLB-infected trees productive …
A bed system used in citrus groves is still under research at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center (NFREC) in Quincy. But one researcher is already convinced that the system, which includes fabric mulch, is beneficial for growers. “This system is better for them. It’s already being used in …
Citrus under protective screen (CUPS) continues to spread across the Florida landscape. The practice is allowing growers to produce high-yielding and high-quality fruit. Roughly 1,500 acres are now planted under screen in Florida. MEET CUPSchat Arnold Schumann, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor of soil, water and ecosystems sciences, pioneered CUPS research in Florida. His …
The October All In For Citrus podcast features citrus under protective screen (CUPS). Over the past decade, the practice has grown in popularity due to its ability to exclude the Asian citrus psyllid and huanglongbing (HLB) disease. Roughly 1,500 acres of citrus are grown under screen in Florida with more acreage under development. Lauren Diepenbrock, associate professor of entomology at …
Pruning is an important management tactic that cold-hardy citrus growers need to implement, especially during the early stages of tree development. Fernando Alferez, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus horticulturist, discussed pruning during the Cold-Hardy Citrus Field Day and Workshop in Quincy on Oct. 1. “Pruning is important because it will give the tree …
As every Florida citrus grower knows, it has been difficult to grow trees and fruit profitably since huanglongbing (HLB) disease was discovered in the state in 2005. Soon after the disease was discovered, officials determined it couldn’t be eradicated largely because the Asian citrus psyllids (ACP) that spread it showed up years earlier and were in virtually all citrus-producing regions. …
By Edwin Gutierrez-Rodriguez and Bosques Jonael Efficient water use in citrus production, like other fruit tree crops, goes far beyond simply turning on the irrigation system. It’s a strategic practice that affects tree health, fruit quality and long-term sustainability, making it a smart agricultural practice. Some key tips to optimize your water management are: Remember, water is also a signal, …
Recent research has shown that systemic acquired resistance (SAR) sprays can protect young citrus tree flushes from Asian citrus psyllid (ACP) feeding, HLB and citrus canker. ACP is the vector that spreads HLB disease from tree to tree. Researchers with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and Bayer Crop Science report that SAR sprays can …
Nazneen Qureshi, a University of Florida (UF) graduate research assistant, is investigating how photoperiod — the amount of light a plant receives each day — can help citrus fruit tolerate cold weather. Qureshi’s research is done alongside UF Institute of Food and Agricultural Sciences (UF/IFAS) Assistant Professor Muhummad Shahid. The research looks at whether the amount of light a plant …
Freeze tolerance is a focal point of citrus studies conducted at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center in Quincy. As citrus production continues to grow in the cold-hardy citrus region, growers need varieties that are able to withstand prolonged periods of sub-freezing temperatures. Leading that research is Muhammad Shahid, …
A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher recently highlighted a number of benefits from using silicon as a nutrient for citrus. Muhammad Shahid, assistant professor at the North Florida Research and Education Center, presented silicon research findings at the Citrus & Specialty Crop Expo in August. According to Shahid, silicon is categorized as a plant …
Blood oranges may be an enticing fruit to grow for cold-hardy citrus producers in North Florida, South Georgia and South Alabama. Muhammad Shahid, assistant professor of horticulture at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), highlighted his blood orange research during the Cold-Hardy Citrus Field Day and Workshop at the North Florida Research and Education Center …
Not far from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) in Lake Alfred, Jason Griffin owns and operates a commercial citrus grove. While commercial in nature, the grove also has become a working experiment for the CREC citrus breeders. Griffin has worked closely with UF/IFAS citrus breeder Jude Grosser to …
At the recent Citrus & Specialty Crop Expo, Ozgur Batuman reminded seminar attendees there is no silver bullet for HLB management. Instead, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher proposes that growers integrate several tools for the management of HLB. These tools include a variety of ways to control HLB-spreading psyllids; oxytetracycline (OTC) trunk injection; …
Breeding efforts to develop citrus trees resistant to HLB are well underway. But how long does the process take before trees are available to growers? Manjul Dutt, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, addresses this question and more in the Citrus Industry section of the October issue of Specialty Crop Grower magazine. His article …
