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.

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.

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 …
Tim Hurner, Peter McClure and the late Richard Kinney were inducted into the Florida Citrus Hall of Fame on March 8 in ceremonies at Florida Southern College (FSC).

Highlands County Extension director and citrus agent Laurie Hurner discussed Valencia oranges, postbloom fruit drop (PFD) and nutrition in summarizing a recent grower forum she hosted. “I think that the overarching feeling (of growers) is positive,” Hurner said. “It seems that Valencias are coming on strong; everybody’s seeing a good crop that’s hanging on the tree. So I think we’ll …
Citrus research continues to be a topic in state and federal funding circles as the industry’s battle with HLB, or citrus greening, continues. One idea in the incubator of industry discussion is the Citrus Research and Field Trial (CRAFT) program. It would involve large-scale grower field trials throughout Florida. Rick Dantzler, chief operating officer of the Citrus Research and Development …
Michael Rogers recently said there is increased optimism in the Florida citrus industry. “With that optimism, growers are starting to give more consideration to replanting,” said Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in Lake Alfred.

The University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) researcher known for his work on the timing of bloom sees the potential for good bloom this season. “Flowering for Florida’s next citrus crop has been coming along fairly well,” UF/IFAS Emeritus Professor Gene Albrigo said in a Feb. 13 interview. He expects the first wave of spring flowers …
By Megan Dewdney The Florida citrus-growing seasons of 2017 and 2018 were quiet in terms of fungal foliar disease outbreaks. Small pockets of severe disease occurred sporadically, but there were no widespread reports of diseases like postbloom fruit drop, much to the relief of the industry. Greasy spot has flared up in a few locations on cultivars like Valencia, and …
By Evan G. Johnson The citrus canker season is just over a month away, so it is time to plan a canker management program to avoid fruit drop or fresh market quality loss. With the current state of HLB in Florida, it is easy to forget some of the other potentially crop-destroying pests in the grove, especially when, unlike HLB, …
