Rootstock Choice May Be Key in Tree Productivity
Florida citrus growers recognize the Sugar Belle® mandarin hybrid for its tolerance of citrus greening disease, and new findings from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) suggest that rootstock selection may play a role in keeping Sugar Belle® trees productive even if they become infected with the bacterial malady. “We now have proof of concept …
UF/IFAS Researchers Search for Solutions to Citrus Diseases with Citrus Initiative Funds
From nutritional supplements to managing irrigation to grower outreach and education, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are finding additional ways to support Florida citrus growers in their fight against citrus greening disease. Twelve projects were funded by the state legislature-funded Citrus Initiative program in 2017-2018 that looked at possible short- and long-term solutions that …
Lemons in Florida: Something New Under the Sun?
By Fred Gmitter, Bill Castle and Jude Grosser King Solomon once pointed out that “there is nothing new under the sun,” meaning that what has happened before will happen again. Although the idea of growing lemons in Florida is viewed by some these days as a new thing, Florida actually has a fairly long history of lemon production. FLORIDA LEMON …
HLB Alters Nutrition Needs
Yield and fruit size are not good measurements of the nutrition needs of HLB-affected trees, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have discovered. “So we decided to go with something that’s fruit independent for the study,” says UF/IFAS scientist Arnold Schumann of the Citrus Research and Education Center at Lake Alfred. Schumann says he and …
Texas A&M AgriLife Research, Consortium Get Grant for HLB Research
A Texas A&M AgriLife Research scientist at Weslaco will lead a consortium of researchers in major citrus-producing regions to conduct high-throughput screening in discovering antimicrobials that could prevent citrus greening. Citrus greening, also known as huanglongbing (HLB) disease, has devastated citrus fruit crops in Florida and has made its way to Texas and California. The research grant of approximately $1.2 …
The Sweet Spot
Moderate spacing and medium tree size could be the quickest way Florida growers can return to producing 100 million boxes of oranges per year. By Pete Spyke, Bill Castle and Ed Stover The Florida Department of Citrus (FDOC) recently released the results of a study originally titled “Restoring Florida’s Commercial Orange Tree Inventory: Economic Impacts of APS vs. Traditional Plantings.” …
Scientists Use Fungus to Manage Asian Citrus Psyllids
Fighting plant disease with jet blast sprays is standard practice for citrus growers. But, to spray a fungus to control a single insect that carries a disease-causing pathogen is uncommon. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and Florida Research Center for Agricultural Sustainability researchers have begun to test an insect-killing fungus applied with horticultural oil …
Black Discusses New CRDF Chief Operations Officer
Citrus Research and Development Foundation (CRDF) President Larry Black discusses the organization’s recent selection of Winter Haven attorney and former state legislator Rick Dantzler as chief operations officer. “Rick wasn’t part of the original candidate pool, but his name emerged in recent weeks as a strong candidate, a good leader,” Black says. “He had a great track record as the …
New CRDF Leader Discusses HLB Battle
Moments after being chosen on July 24 as the next chief operations officer of the Citrus Research and Development Foundation (CRDF), Rick Dantzler declared the industry will “whip” HLB. He chose Aug. 15 as his first day of work so he can meet many growers at Citrus Expo. “I wanted my first day on the job to be with citrus …
Sneak Peek: August 2018 Citrus Industry Magazine
At the center of the August issue of Citrus Industry magazine is the Citrus Expo show guide. Readers will find everything they need to know about Florida’s leading agricultural event. This year, Citrus Expo is expanding its reach to include vegetable and specialty crop growers. The Citrus Expo seminar and trade show is August 15–16 at the Lee Civic Center …
System Stops Psyllid Travel
By Len Wilcox Researchers with the U.S. Department of Agriculture (USDA) believe that an effective measure has been found that will reduce the risk of spreading huanglongbing (HLB) disease between orchards. The control measure is a fogging system with a carrier and a pesticide that effectively destroys disease-bearing insects before they can leave the orchard and do further harm. NO …
Lawmakers Sign Off on Money for Citrus Farmers
Gov. Rick Scott said the state will “soon” begin accepting applications from citrus farmers whose crops and groves were damaged by Hurricane Irma, after the Joint Legislative Budget Commission accepted $357 million in federal funding for the industry on July 19. “It’s great that the LBC approved this funding today,” Scott tweeted. “We look forward to continuing to work with …
Lawmakers Poised to Approve Citrus Farmer Money
Gov. Rick Scott on Wednesday urged the Joint Legislative Budget Commission to approve $340 million in federal block grant funding to help the state’s hurricane-ravaged citrus industry. The money was part of a $2.36 billion disaster-relief package approved by Congress in February. The state Division of Emergency Management will administer the money, leading to the issue going before the Legislative …
Move Your Jets
By Marshall Hartley At Florida Southern College, I remember doing an experiment using a large washtub with holes in the bottom. We filled the tub with very dry sand and then poured 1 inch of water over the sand and let it soak in. The water did not travel through the sand evenly. Instead, the water would find one area …
Research on Heat Treatment, Bactericide Uptake
A University of Florida Institute of Food and Agricultural Sciences researcher reports on an experiment to see if treating trees with heat would enhance the uptake of a bactericide commonly used for HLB. “We treated trees that were not HLB infected, so this wasn’t looking at the efficacy of heat treatment against HLB,” says scientist Christopher Vincent, who works at …
Grower Discusses Hurricane Relief Funds
Vic Story was one of hundreds of growers who attended Florida Citrus Mutual-sponsored meetings in early July describing how Hurricane Irma relief funding will work. “We got hit pretty hard in places last year, and we didn’t pick as much fruit as we thought we were going to, especially earlies (early-season oranges),” Story says. “And so, we can use some …
The Economics of Planting Density in the HLB Era
University of Florida Institute of Food and Agricultural Sciences researcher Ariel Singerman led efforts to analyze the economic viability of planting at different tree densities under endemic HLB conditions. The analysis describes the establishment and production costs of a new grove for three tree planting densities under different market conditions. “Excel files containing the analysis and a companion file describing …
