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 …
Citrus Research at SWFREC
Southwest Florida Research and Education Center (SWFREC) Director Kelly Morgan provides an update on citrus research being conducted at the center. SWFREC is operated by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Morgan says most of the research is “related to greening, but not all of it.” Greening is another term for huanglongbing (HLB), the citrus …
Voluntary Best Practices for California Citrus Growers’ Response to HLB
Best Practices Developed by Grower-Led, Science-Supported Task Force To provide California citrus growers with a strong toolbox of science-supported strategies and tactics to protect their orchards from huanglongbing (HLB), the Citrus Pest & Disease Prevention Committee endorsed a set of best practices for growers to voluntarily employ in response to HLB in California. The recommendations — which were developed based …
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 …
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 …
Update on Brassinosteroids for HLB Management
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 …
TCP Might Help Trees Tolerate HLB
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 …
Study Aims to Use Orange Peels for Better Heart Health
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 …
Farewell to Futch
After 34 years of faithful service to citrus growers, University of Florida Extension agent Steve Futch readies for retirement.

UF/IFAS Tops in Research
“There is no program anywhere in the country better than IFAS (University of Florida Institute of Food and Agricultural Sciences) in conducting both applied and basic research.” That declaration is made by Scott Angle, director of the U.S. Department of Agriculture National Institute of Food and Agriculture, in the latest episode of the All in for Citrus podcast. Angle became …
Precision Agriculture Technologies in Citrus
By Yiannis Ampatzidis Citrus growers face issues from an increasing number of pests and diseases. Rapid and accurate tools for early pest and disease detection are needed to improve precision and timely management. Almost all agrochemicals (e.g., pesticides) applied in specialty crop production are made uniformly with conventional spraying equipment, despite the fact that pathogen distribution is typically patchy. Uniform …
California Citrus Mutual Opposes Chlorpyrifos Ban
California Citrus Mutual (CCM) has issued a statement opposing the upcoming statewide ban of chlorpyrifos. The California Environmental Protection Agency (CalEPA) announced that the Department of Pesticide Regulation (DPR) is now working to rescind the approved use of the pesticide, which will effectively ban the pesticide from any use in California. The process could take up to two years. CalEPA …
Tree Infected with HLB Found in Riverside, California
The California Department of Food and Agriculture (CDFA) stated last week that a second tree has tested positive for HLB disease, also known as citrus greening, in Riverside County. Due to being in a previously identified detection area, the tree had been tested several times previously but had not shown indications of the disease. The CDFA is in the process …
An Important Reminder on Citrus Tristeza Virus
