Individual protective covers (IPCs) on young trees have prevented HLB infection in one year of study, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher said. Fernando Alferez, citrus horticulturist at the Southwest Florida Research and Education Center (SWFREC), announced his promising results at the recent Florida Citrus Show in Fort Pierce. “They (IPCs) are protecting the …
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 …
By Ernie Neff Jerry Mixon’s use of netting to keep birds from blueberries helped pique his interest in growing citrus under protective screen (CUPS) to exclude HLB-spreading psyllids. But he credits University of Florida researcher Arnold Schumann with helping him bring his Polk County CUPS project to fruition. Mixon met Schumann in 2015, the year after Schumann’s 1-acre CUPS was …

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 …
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 …
Florida’s grapefruit industry, devastated by citrus greening, may find hope in four ½-acre white-mesh screenhouses in a research field in Fort Pierce. The project will be funded by a $3.5 million grant from the U.S. Department of Agriculture (USDA) awarded to the University of Florida. Studies for the grant will take place inside and outside these structures, where 512 young …
By Len Wilcox Research into high-density citrus plantings is gaining momentum at both ends of the country. In a study funded by the California Citrus Research Board, scientists are evaluating the consumption of water and other inputs used by high-density dwarf citrus trees. The scientists want to determine costs while the trees are maintaining high production levels. In Florida, researchers …
Numerous researchers have collaborated on an attract-and-kill device that will hopefully eliminate psyllids in confined spaces, such as nurseries and citrus under protective screen (CUPS). University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lukasz Stelinski reports on a presentation he made Oct. 25 at a citrus nursery workshop in Lake Alfred. Stelinski says researchers with UF/IFAS and …
Growers looking for good news will find it in the November issue of Citrus Industry magazine. The positive news begins with the prediction that Florida is on pace to increase orange production by 76 percent this season. The U.S. Department of Agriculture’s initial citrus crop forecast is the subject of the issue’s cover story. Industry members share their reactions to …
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 …
By Arnold Schumann, Laura Waldo, William Holmes, Gary Test and Tim Ebert Artificial intelligence (AI) is increasingly common in electronic devices at home or work, in social media, video streaming services, electronic commerce, and in internet search engines. Now, AI is rapidly entering the farming scene. Growers using modern precision agriculture tools and techniques often face a barrage of high …
Phil Stansly, University of Florida Institute of Food and Agricultural Sciences entomologist, discusses alternatives to imidacloprid for helping to control HLB-spreading Asian citrus psyllids (ACP). “Imidacloprid of course is typical of the neonicotinoids that we’ve been using as soil applications to protect young trees,” Stansly says. “We’ve seen and the growers have seen, too, that soil applications of systemic insecticides …
By Jawwad A. Qureshi, Philip A. Stansly and Lukasz L. Stelinski Pest management has always been important for citrus production in Florida. It has become even more critical following invasion of the Asian citrus psyllid (ACP) and citrus leafminer (CLM), due to their association with huanglongbing (HLB or citrus greening) and canker diseases, respectively. ACP and CLM develop and reproduce …
By next year, a fence utilizing light sources is expected to be available to help protect some citrus structures and maybe even grove perimeters from the HLB-spreading psyllid. U.S. Department of Agriculture research entomologist Joe Patt explains the technology. “Photonic fence is a multi-modal system that uses several different types of light in order to detect, track, identify and, if …
With citrus greening devastating Florida’s $8.6 billion-a-year citrus industry, three University of Florida scientists will use $10.52 million in federal grants to study ways to help growers cope with the disease, including research on genetic editing that may produce potentially resistant fruit and trees. Since greening — or huanglongbing (HLB) — was first reported in Florida in 2005, Florida’s citrus …
Economist Tom Spreen thinks advanced production systems (APS) and citrus under protective screen (CUPS) offer hope for some growers in the face of HLB. Spreen, a University of Florida Institute of Food and Agricultural Sciences professor emeritus, discussed APS and CUPS at a recent Gulf Citrus Growers Association economic seminar in LaBelle. Spreen says growing with APS “means you have …
University of California Riverside (UCR) is committed to a major offensive against huanglongbing (HLB, or citrus greening disease), as the threat is marching ever closer to commercial citrus orchards in California. The only confirmed cases in Southern California have been in residential trees in Los Angeles and Orange counties, including near the UCR campus. But some experts believe it is …
By: Brad Buck, 352-294-3303, bradbuck@ufl.edu GAINESVILLE, Fla. — Grapefruit grows better under screen houses than in unprotected groves because the indoor facilities keep out the insect that causes citrus greening, new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research shows. Protecting citrus from greening is essential, UF/IFAS researchers say. The disease, first detected in Florida in 2004, …
Walls consisting of insect-proof screen held up by telephone poles hold promise for helping growers reduce the cost of controlling HLB-spreading psyllids. The walls serve as artificial windbreaks in a new model grove planted in June at the Citrus Research and Education Center (CREC). The grove was one of numerous projects viewed by more than 500 attendees who came to …
