Jackie Burns, who retired in January as dean for research at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), discusses HLB, mechanical harvesting and other citrus issues on which she worked. Burns was a long-time scientist at the Citrus Research and Education Center and later director of the center before becoming dean for research. Burns said going …
Commercial citrus growers will soon see a new seedless mandarin variety that stays on the tree longer, two traits farmers seek, say University of Florida scientists. Marathon, an early season mandarin, is also easy to peel and tastes good, said Fred Gmitter, a professor of breeding and genetics at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). …
What is a pesticide, really? By Laurie A. Hurner 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. There is a lot of confusion about the term “pesticide” when you talk to …
Florida grapefruit trees have taken a much harder hit from HLB, also known as greening disease, in recent years than orange trees have. Grapefruit production has plummeted drastically, and growers are desperately seeking ways to keep trees alive and productive. The fruit’s troubles have hit especially hard in the Indian River area, known worldwide for its grapefruit. Indian River Citrus …
Michael Rogers, director of the Citrus Research and Education Center, discusses HLB research and education programs being conducted by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). “The goal of our IFAS citrus program continues to be to provide growers with the most up-to-date information that they can use to help maintain or increase the production of …
A shift toward reduced use of insecticides in Florida groves could lead to the emergence of pests that haven’t generally been a problem for years, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock said. Pests that could return or emerge in the face of reduced insecticide use include scales, mealybugs, false spider mites and fruit …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lukasz Stelinski suggested ways growers can cut psyllid control costs. He summarized key points he made in a talk at a Jan. 8 Citrus Insect Management Workshop at the Citrus Research and Education Center in Lake Alfred. Stelinski credited the late UF/IFAS entomologist Phil Stansly for determining that psyllid …
By Jawwad Qureshi, Lukasz Stelinski and Fernando Alferez Management of huanglongbing (HLB) has focused on reducing the vector Asian citrus psyllid (ACP) and improving tree health, thus requiring a multi-pronged approach. Several elements of an HLB management system are either available or under current investigation. Maintenance of clean nursery stock, vector management and tree nutrition are widely implemented, while incorporation …
Growers with trees affected by HLB should try to maintain soil pH in the 6 to 6.5 range, Kelly Morgan told numerous growers attending a recent Citrus Nutrition Day event. Morgan is director of the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Southwest Florida Research and Education Center. Morgan explained that soil pH affects trees’ ability to …
Daily irrigation is important in managing HLB-affected trees, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) soil scientist told a Citrus Nutrition Day crowd in Bartow on Dec. 11. The researcher, Davie Kadyampakeni, said daily irrigation reduces tree water stress and improves tree water use. According to Kadyampakeni, keeping water in the top 12 inches of soil …
A new report from economists with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Economic Impact Analysis Program (EIAP) showed higher prices offset production declines during Florida’s 2016-17 citrus growing season, and the industry’s overall economic contributions changed little from 2015-16. Titled, “Economic Contributions of the Florida Citrus Industry in 2016-17,” the report was formally presented to …
An agricultural engineer whose current research projects include the simulation of agricultural management impacts on water quantity and quality in the upper Floridan aquifer has joined the University of Florida’s Indian River Research and Education Center (IRREC). Sandra Guzmán will lead the center’s irrigation and hydrology program. Guzmán started her position as an assistant professor of agricultural and biological engineering …
Citrus growers can learn more about managing Asian citrus psyllids and other pests in a workshop Jan. 8 at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC). The psyllid can transmit the bacteria associated with greening disease to citrus trees and has already caused severe damage to Florida’s multi-billion-dollar-a-year citrus industry. …
A Citrus Nursery Production Guide is expected to be published by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) in five or six months. “We are going to cover the basics of nursery production,” said UF/IFAS researcher Rhuanito (Johnny) Ferrarezi. “Then we will help (with) selecting varieties. We will talk about … how to clean material, how …
This year’s Citrus Nutrition Day — at which growers will learn the latest data about growing the fruit, from the soil up through the plants — is expanding to include tours of field trials. After a morning of updates from University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers, participants may tour field sites at the Peace River …
Florida citrus growers have begun taking notice of kaolin clay, a powdery white compound, because it can cause Asian citrus psyllids (ACP) to “not take notice” of their groves. Long used to protect other fruit and vegetable crops, kaolin can also conceal citrus trees from hungry psyllids by confusing their visual sensory system, said Michael Rogers, director of the Citrus …
Florida citrus growers who plan to establish new groves might want to consider high-density planting, according to experts with the Citrus Research and Education Center (CREC) in Lake Alfred, part of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Wider spacing between trees and rows was common decades ago but, with yields down and input costs up, …
By Arnold Schumann, Timothy Ebert, Laura Waldo, Danny Holmes, Napoleon Mariner, Gary Test, Chris Oswalt, Rhuanito Ferrarezi and Ricardo Lesmes Two studies with citrus under protective screen (CUPS) were established at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) and Indian River Research and Education Center (IRREC) in 2013–14. The goal …
By Rhuanito Ferrarezi, Alan Wright and Arnold Schumann High-density plantings have been tested worldwide in advanced citrus production systems (ACPS) to increase efficiency of water, fertilizer and light, and to maximize yield per area. After the onset of huanglongbing (HLB) in Florida, canopy growth reduced drastically due to negative impacts on plant health, creating the need for new plant spacing …
Jerry Mixon of KLM Farms hosted about 40 growers, researchers and others at his citrus under protective screen (CUPS) facility in Alturas on Nov. 15. Alturas is between Bartow and Lake Wales in Polk County, Florida. At the field day, Mixon discussed his experience with the growing system and his expectations for it. He has 30 acres under screen that …
