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 …
By Tripti Vashisth, Lisa Tang and Sukhdeep Singh In citrus, huanglongbing (HLB) causes an increase in the mature fruit drop rate up to three months prior to commercial harvest. This preharvest fruit drop results in a great reduction in yield and overall grove productivity. Since the plant growth regulators that improve fruit retention on healthy trees do not have consistent …
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 …
“A bigger gorilla by far than HLB, going into the future, is slumping market demand for citrus products from Florida and apparently from other producing areas in the United States as well,” declares Apopka citrus grower Chip Henry of McGuire Groves. He believes the decline in demand for Florida citrus products is related to HLB reducing fruit quality. “Consumers are …
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 …
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 …
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. …
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 …
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 …
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 …
Joel Nelsen, former president of California Citrus Mutual, has been reappointed to the Fresh Fruit and Vegetable Agricultural Technical Advisory Committee. This committee advises the U.S. secretary of agriculture and the U.S. trade representative on a myriad of policy issues. Nelsen has served on this committee since the George W. Bush administration. He has been the committee chair for the …
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 …
After serving nearly 10 years as the senior vice president for agriculture and natural resources with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), Jack Payne announced he will retire next year. His last day with UF/IFAS will be July 1, 2020. Payne has overseen Extension offices across Florida and its 12 research and education centers since …
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 …
By Fernando Alferez, Christopher Vincent and Tripti Vashisth Brassinosteroids (BR), a relatively newly discovered class of plant hormone, regulate several developmental and physiological processes in fruit crops such as grapes, pears and cherries and in some non-edible plants. BR also induce disease resistance against different pathogens in a great number of crop plants. A form of BR (epibrassinolide) was shown …
Arnold Schumann, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor of soil science, reports on his five years of research into citrus under protective screen (CUPS) for fresh fruit. He is one of the first researchers in Florida to do extensive, hands-on research into the system. His discussion is part of the current All In For Citrus …
A direct support organization (DSO) to be established within the Florida Department of Agriculture and Consumer Services will reportedly run the massive Citrus Research and Field Trials (CRAFT) program. Florida Citrus Mutual CEO Mike Sparks announced the pending arrangement June 13 during the Florida Citrus Industry Annual Conference in Bonita Springs. The CRAFT program features an expected 5,000 acres of …
Laboratory tests of tricalcium phosphate (TCP) indicate it has potential use as a fertilizer that might help citrus growers cope with HLB, says Laura Waldo, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) laboratory manager. “The hope is that it can help a tree by inducing root hair development and thereby allowing the tree to uptake nutrients …
You’ve heard an apple a day keeps the doctor away. Now orange peels may improve your heart health. Yu Wang, an assistant professor of food science and human nutrition at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), has been awarded a $500,000 grant from the U.S. Agriculture and Food Research Initiative, part of the U.S. Department …
After 34 years of faithful service to citrus growers, University of Florida Extension agent Steve Futch readies for retirement. By Tacy Callies Steve Futch’s Florida citrus roots sprouted more than a century ago. His great-grandfather owned a Wauchula grove in about 1905. As a boy, Futch’s first hands-on citrus experience was hoeing trees in the family orange groves. Later, he …
