Citrus Numbers Improve as Struggles Continue
Florida’s citrus industry ended its growing season on a slight uptick, regaining the Sunshine State’s dominance in orange production over California. But struggles remain. Growers, who last year posted 75-year lows because of damage caused by Hurricane Irma, still are at diminished production levels that hadn’t been seen in decades as they face deadly citrus-greening disease and factors such as …

He explains that the visit was very valuable for the National Institute of Food and Agriculture (NIFA) officials because they got to …
Update on Grapefruit Nutrition
University of Florida Institute of Food and Agricultural Sciences researcher Rhuanito “Johnny” Ferrarezi reports on research leading to fertilizer recommendations for grapefruit, especially in the Indian River area. Grapefruit has been especially hard hit by HLB, the devastating citrus disease discovered in Florida in 2005. “We are entering the second season (of the research project) and we hope to have …
How One Small Grower Handles HLB
By Ernie Neff It’s common belief — and probably true — that small Florida citrus growers have suffered more than larger growers as a result of HLB. Del Murphy might agree, but his family’s 66-acre citrus grove east of Avon Park is doing well by any Florida standard. He says the Murphy Partnership production program seems to be working “as …
Psyllids, Yield and Weed Control
Recent University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research shows that HLB-spreading psyllids can feed on weeds, and that good weed control can increase fruit yield. The research results were presented by UF/IFAS weed scientist Ramdas Kanissery, who works at the Southwest Florida Research and Education Center (SWFREC) in Immokalee. Kanissery said his work on psyllids feeding …
UF/IFAS Helps Assess, Manage New Fruit Bug
Researchers with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are already trying to help growers figure out how to effectively manage the problems created by an invasive pest – confirmed last week in Highlands County — that could further erode citrus production at a time when growers are just beginning to turn the corner on managing …
PIECES OF THE PAST: Back When Bushel Baskets Were the Next Big Thing
By Brenda Eubanks Burnette While some things stay the same in citrus, others clearly do not. Today’s growers are experimenting with drones and other technology in the grove, but back in the 1920s, bushel baskets were making waves in the industry. Here’s an interesting excerpt from a March 1921 Citrus Industry article titled “Citrus Fruits in Bushel Baskets” by M.S. …
Orange Grower: ‘Best Year I’ve Ever Had’
Hardee County orange grower Kenny Sanders said at a grower roundtable meeting on June 25 that he produced 409 boxes per acre in the 2018–19 Florida citrus season. “This is the best year financially I’ve ever had in the citrus business,” Sanders said at the Wauchula gathering hosted by Peace River Valley Citrus Growers Association. “In 2012, I picked 500 …
Getting HLB Material Into Phloem
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant pathologist Ozgur Batuman discusses efforts to get materials that fight HLB into the citrus tree’s phloem, where it might be most effective. Batuman explains that bacteria that cause HLB “live inside the phloem of citrus. That is very difficult to reach to kill … by conventional methods, such as …
Sneak Peek: July 2019 Citrus Industry Magazine
Four articles on grove management will give citrus growers food for thought in the July issue of Citrus Industry magazine. The first article tells how one grower handles HLB. Del Murphy discusses production practices that have helped him cope with the disease. Bactericides, irrigation and nutrition management are among the topics he addresses. The second article is for growers who …
Understanding Glyphosate Formulations
By Ramdas Kanissery, Steve Futch, Brent Sellers and Camille McAvoy Glyphosate is a popular post-emergent herbicide among Florida citrus growers for its broad-spectrum of weed control under trees and in row middles. The use of glyphosate as a “burn-down” application alone, or in combination with other herbicides, is a standard practice in citrus groves. Various glyphosate-containing product formulations are available …
Technology: Consider the Costs
Tara Wade, a University of Florida Institute of Food and Agricultural Sciences economist, has some advice for growers considering new technology for the grove. “What we’d like growers to do is start to think about all the costs involved … do the math before they invest,” she says. “Growers have to constantly think about the trade-offs” of adopting new technology …
Studying Citrus Greening with an Integrated Approach
While citrus growers continue to look for best management approaches to deal with the deadly greening disease, scientists will take an integrated look at how to protect young trees by using existing tools growers can use. Five scientists from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) will compare insect management tools, including insect-proof netting. Researchers also …
Study Shows Mandarin IPM Needs Work
According to a study published in the Journal of Economic Entomology, current integrated pest management (IPM) techniques used in California mandarins may need to be adjusted to allow for differences between mandarins and oranges. The study suggests that following guidelines for oranges may lead to an overuse of pesticides in some situations. Almost all mandarins in America are grown in …
