By Tripti Vashisth, Davie Kadyampakeni and Lushan Ghimire In the past few years, horticultural citrus grove management practices have changed significantly in Florida. It is a common observation across the state that huanglongbing (HLB)-affected trees respond well to complete and balanced nutrition programs. Therefore, citrus growers are currently focusing on intensive management of irrigation and nutrition. HLB-affected trees suffer a …
Controlling HLB-spreading Asian citrus psyllids along grove borders can be part of a cost-efficient psyllid control program, says University of Florida Institute of Food and Agricultural Sciences entomologist Lukasz Stelinski. “Psyllids are found in borders in much greater frequencies than any other place within the grove,” Stelinski says. “This is a place that they congregate … Anything that helps protect …
Numerous Florida citrus growers have recently put mesh bags over individual young citrus trees to exclude HLB-spreading Asian citrus psyllids. A topic title at the 2019 Florida Citrus Growers’ Institute asked whether the practice is profitable. The presentation was made by University of Florida Institute of Food and Agricultural Sciences economist Ariel Singerman. “The answer to the question of whether …
Researcher Rhuanito “Johnny” Ferrarezi recently discussed experiments on citrus varieties and citrus under protective screen (CUPS) in the Indian River area. Ferrarezi is a University of Florida Institute of Food and Agricultural Sciences assistant professor of citrus horticulture at the Indian River Research and Education Center (IRREC). One large trial Ferrarezi discussed will be of grapefruit, navel and mandarins on …
About 20 people attended an informational program on April 9 at the Citrus Research and Education Center in Lake Alfred, Florida. The meeting addressed the newest Fast Track program variety, Marathon, being released. Marathon is an early-season seedless mandarin.

By Sarah Strauss, Davie Kadyampakeni, Ramdas Kanissery, Tara Wade, Lauren Diepenbrock and Juanita Popenoe Cover crops are specific crops not intended for sale but for soil improvement and sustainability. They are increasingly common in the agricultural fields of the Midwest and other grain-producing regions because of the wide range of benefits not just for the soil, but also the cash …
Organic insecticides rotated with either spray oil or insecticidal soap provided good Asian citrus psyllid (ACP) suppression in long-term studies in Florida, entomologist Jawwad Qureshi reported recently. Qureshi is a University of Florida Institute of Food and Agricultural Sciences researcher at the Southwest Florida Research and Education Center in Immokalee. Suppression of ACP is important because the pest spreads citrus …
Yu Wang says a key element of her job is finding “how to improve the citrus flavor and how to understand consumer likings” of Florida orange juice. Wang is a University of Florida Institute of Food and Agricultural Sciences researcher at the Citrus Research and Education Center in Lake Alfred. “Some of our consumers, they really like that orange flavor; …
By Juanita Popenoe and Lauren Diepenbrock Ed James has citrus in his veins. He has been working and thriving in the citrus business since he was a teenager — from hoeing orange trees to owning a caretaking business that serviced thousands of acres. That is, until about eight years ago. In 2010, James looked around his personal 45-acre citrus grove …
By Lauren Diepenbrock In October 2018, a potential “new pest” was found in large numbers in one grove in Hernando County, Florida. The damage to trees was dramatic, with dark staining throughout the trunk of the tree and beetle damage evident. It was something that would put any grower, Extension agent or researcher on alert. Fortunately, by working with Jiri …
Grapefruit’s struggle with survival and potential future were addressed by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) breeder and geneticist Fred Gmitter earlier this year. He told Florida Citrus Show attendees that the fruit has hit the bottom with HLB. “I was talking with one of the old-time families in the grapefruit business, one of the biggest …
As Florida citrus growers learn to live with HLB, greater attention is being paid to plant nutrition. Nutrition takes center stage in the April issue of Citrus Industry magazine. Both growers and researchers are exploring the use of cover crops in grove row middles to enhance tree nutrition. The April issue includes a case study on eight years of cover …

Rogers said multi-county citrus Extension agents have been putting the Institute program together …
Citrus Research and Development Foundation (CRDF) President Larry Black discusses the organization’s potential role in large-scale field trials to demonstrate how citrus can be grown in the face of HLB. He also talks about a communication study showing how growers like to receive information about CRDF. The Citrus Research and Field Trial (CRAFT) program would be funded for approximately $8 …
The University of California, Riverside (UCR) has received a $3.5 million donation from Givaudan to support UCR’s Citrus Variety Collection. The gift will help build a screened structure to protect the collection from the impending threat of citrus greening disease, also known as huanglongbing (HLB). The 2.8-acre protective screened structure will house new trees and back-up collections of the UCR …
By Larry Duncan Successive hard freezes in Florida in the late 1980s resulted in widespread replanting of citrus groves. Within a few years, many groves on the Central Ridge had discrete patches of poorly growing, chlorotic young trees amid patches of vigorously growing trees. Stubby root symptoms on the declining trees suggested damage by sting nematodes (Belonolaimus longicaudatus). This nematode …
The California Department of Food and Agriculture (CDFA), working in cooperation with the Sacramento County agricultural commissioner, has placed Sacramento County under a plant pest quarantine for the Asian citrus psyllid (ACP) following the detection of one ACP in Sacramento’s Lemon Hill area. The quarantine prohibits the movement of citrus and curry leaf tree nursery stock and all plant parts, …
By Evan Johnson Diseases caused by phytophthora continually threaten Florida citrus production. Brown rot can directly reduce yields of early maturing varieties including Hamlin and grapefruit, can delay harvest of fresh market fruit until infected fruit have dropped, or risk packinghouse rejection of the load because it can spread post-harvest. Foot and crown rot can kill trees but are uncommon …
