Cover crops, which are not planted for harvest and sale, offer numerous potential benefits to Florida citrus growers. The benefits and additional information were addressed in a presentation offered at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) booth at Citrus Expo in August. The crops can improve the physical, chemical and biological properties of the soil. …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) multi-county citrus Extension agent Ajia Paolillo discussed brown rot management in the September Extension newsletter, Citrus from the Ridge to the Valley. Her article follows. As we move into September, it is essential to remember that brown rot can impact yield, especially early varieties. Brown rot is caused by either …
Work on finalizing a newly revised citrus best management practices (BMPs) manual has slowed, and that’s a good thing, according to Highlands County Citrus Growers Association (HCCGA) Executive Director Ray Royce. In a recent HCCGA newsletter article, he stated that a number of issues, especially related to nutrient management and application efficiency, need to be better understood. “It is the …
By Davie Kadyampakeni, Evan Johnson, Kelly Morgan and Ali Atta Citrus production in Florida has been decreasing over the last 15 years due to several factors, with huanglongbing (HLB) a major driver. This disease has severe effects on citrus growth and production, including stunted vegetative growth, misshapen small fruits and poor color development, root mortality, stunted branches, excessive fruit drop, …
Many Florida citrus growers were among the approximately 300 people who registered for a Sept. 21 virtual seminar telling how gibberellic acid (GA) can improve Valencia orange yields. Valencias, at 30.1 million boxes, made up slightly more than half of Florida’s total citrus crop in the 2020-21 season. Presenter Tripti Vashisth started her presentation by saying that GA, already available …
By Rhuanito S. Ferrarezi, Waqar Shafqat, Hernan Soto, Mark Ritenour, Lorenzo Rossi,Davie Kadyampakeni, Evan Johnson and Kelly Morgan Florida citrus growers have been using high-density planting and different soil and foliar fertilizer application strategies to compensate for the adverse effects of huanglongbing (HLB). Recent studies indicate that high-density plantings and enhanced nutritional programs with higher micronutrient levels, such as the …
The September episode of the All In For Citrus podcast is a special edition focused on one subject. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have identified a breakthrough treatment for huanglongbing (HLB) that greatly reduces the effects of the disease. Michael Rogers, director of the Citrus Research and Education Center, said a lot of UF/IFAS …
A Citrus Expo presentation about best management practices (BMPs) focused on what growers should be doing now in their irrigation and nutrient management programs. The presentation noted that current BMPs were developed prior to HLB’s discovery in Florida in 2005, and that studies are underway to revise the citrus BMPs for nitrogen and phosphorus. The presentation was created by University …
The next key to winning the battle against citrus diseases such as citrus canker may be in the tiniest microbes that live inside the citrus tree. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers hope to discover how these microbes may benefit citrus trees in their natural fight against diseases. The end result may be an environmentally …
The Florida Citrus Commission (FCC) recently heard presentations about the history and current work of both the New Varieties Development and Management Corporation (NVDMC) and the Citrus Research and Development Foundation (CRDF).

By Yiannis Ampatzidis and Ute Albrecht Nutrient management is important for citrus production. Regular nutrient assessments should be conducted to optimize nutrient balance and prevent deficiencies or over-fertilization. Optimizing nutrition is important for tree health and can improve tolerance to stresses and diseases. Good nutrient management requires regular field monitoring to identify problems and examine crop responses. Leaves need to …
Citrus tristeza virus (CTV) is still present in Florida and can be transmitted to new trees, especially during brown citrus aphid outbreaks, according to the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). A presentation about surveying for CTV was available at the UF/IFAS booth during Citrus Expo in August. The presentation noted that switching to sour orange …
A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher recently determined how bacterium causes the devastating citrus disease HLB. Information about further research into ways the discovery can help growers reverse the effects of HLB and improve tree health will be presented this fall.

The economic trends of Florida’s citrus industry and how the impacts of a natural disaster are determined were discussed recently by a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) economist. Christa Court, assistant professor of regional economics and director of the UF/IFAS Economic Impact Analysis Program, said Florida citrus production and yield are trending downward. “But we …
An innovative way to manage huanglongbing (HLB) disease is producing impressive results in University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research. According to Arnold Schumann, UF/IFAS professor at the Citrus Research and Education Center (CREC), citrus under protective screen (CUPS) production systems have increased yields with zero effect from HLB. He shared research results during a recent …
Fabric mulch landscape covers, typically used to block weeds in nurseries, can aid in diaprepes root weevil control, Larry Duncan reported at the recent Citrus Expo. “Some of these products, not all of them, are extremely effective at blocking the diaprepes weevil larvae from getting into the soil” after falling from a citrus tree, Duncan said. Duncan is a University …
Multi-county citrus Extension agent Ajia Paolillo recently suggested ways to prepare for and recover from a hurricane. Hurricane season began June 1 and ends Nov. 30.
