The International Citrus Congress is taking place this week in Brazil. Scientists and citrus industry members from around the globe are gathering to learn the latest research not just on HLB, but on all aspects of citrus production. Florida is well represented at the event. Harold Browning, Citrus Research and Development Foundation chief operations officer, is among the attendees. Southeast …
Florida Citrus Commission Chairman Ellis Hunt Jr. reacts to projections Wednesday that Florida’s orange production will likely be near current levels or possibly much lower in 10 years. He says existing growers and/or institutional investors could replant trees lost to HLB fairly rapidly if they believe trees can survive and produce fruit in the face of HLB. “I think we …
In the worst-case scenario projected by economists Wednesday, Florida orange production could plummet to 27 million boxes in 10 years. Florida orange production last season was 81.5 million boxes. As recently as the 2003-04 season, Florida produced 242 million boxes of oranges. Production declines are primarily caused by HLB, the deadly disease first discovered in Florida in 2005. But the …
University of Florida researcher Reza Ehsani updated growers at Citrus Expo in August about research into the use of heat treatment of HLB-infected trees. Approximately 80,000 trees were heat treated in Florida in the past year, he says. Ehsani discusses some key issues regarding thermal therapy. “Finding the right time and temperature is critical to using this technique,” he says, …
“I think it just continues to show … the effect of HLB,” citrus grower and Florida Citrus Commission Chairman Ellis Hunt Jr. says of the U.S. Department of Agriculture report that Florida citrus acreage fell 4 percent in a year. “I look forward to the day that the new groves going in the ground will offset the declining numbers.” Hunt …
“I don’t think there were any real surprises in the report today,” Indian River area grower and packer Cody Estes says in response to the U.S. Department of Agriculture’s report that Florida citrus acreage tumbled 4 percent. Florida acreage is now at 480,121, the lowest number since tracking began in 1966. “Hopefully with the anti-microbial treatments that are going on, …
Planting new groves in the face of HLB has become a daunting task for Florida growers. At the recent Citrus Expo, University of Florida researcher Ute Albrecht offered suggestions for those taking on the challenge. “Among the important things to consider when planting new groves are the site preparation, the planting of the trees, weed management, irrigation and nutrition, and …
By Stephanie Slinski Evaluating how well bactericides, nutritional programs or other treatments work against HLB can be difficult. Symptoms are not uniform between trees in a grove, and tree health fluctuates throughout the season, which may give the appearance of an effect. Rigorous field trials are the best way to test new treatments, but not every treatment program can be …
Several citrus growers attending a grower forum in Sebring last week said groves are looking very good even though fruit production is expected to be low this season. John Barben, a Highlands County grower and the new president of Florida Citrus Mutual, summarized the situation. “Trees are looking good,” Barben said. “We had a lot of rain the last couple …
Research on HLB-tolerant trees and better citrus varieties is being conducted in Gainesville, outside the Florida citrus belt. University of Florida scientist Jose Chaparro discusses the work. “In Gainesville we have essentially the youngest citrus breeding program in Florida,” Chaparro says. “In the future, we hope to be able to provide both HLB and canker resistance in our selections.” Such …
Michael Rogers, director of the University of Florida’s Citrus Research and Education Center, discussed the planned HLB Playbook at the recent Citrus Expo. The playbook should be available in print and on the Internet by January. Rogers says the playbook will feature “all the information we know about managing citrus groves in the face of HLB and how growers can …
By Stephanie Slinski and Harold Browning (Editor’s note: Click on the graphs throughout the article to enlarge them.) Bactericides have been available to growers as a new tool to improve the health of HLB-infected trees since early March 2016. This use has been under a crisis declaration from the Florida commissioner of agriculture, but on August 15 of this year, …
Sponsored Content A brand new book, “The Critical Importance of Citrus Tree Nutrition,” recently made its debut at Citrus Expo. Growers who attended the event were able to receive a free copy of the book, courtesy of TKI Crop Vitality. Due to the popularity of the book, TKI is extending the promotion to Florida citrus growers who have not yet …
Harold Browning, chief operating officer of the Citrus Research and Development Foundation, summarizes a Citrus Expo panel in which four growers discussed their use of bactericides for HLB. The bactericides became available for use for HLB this spring. “They’re kind of working in the dark,” Browning says of the panelists and other growers trying bactericides. “They’re having to test and …
Jim Snively of Southern Gardens Citrus says his company is trying bactericides for HLB on one-tenth of its 10,000 citrus acres. The company is working with the Citrus Research and Development Foundation to analyze fruit drop, tree condition and more in blocks treated with bactericides. He believes it will take two to three years to determine if the bactericides are …
U.S. Department of Agriculture scientist Bob Shatters updated Citrus Expo seminar attendees on results from ongoing bactericide research trials. He was among the many speakers who discussed tools for HLB in the seminar program. “The first year of applications, we were detecting reductions in the bacterial population of the plant,” Shatters said. “And we did see that continue after the …
Citrus Expo 2016 Citrus growers and industry members turned out in full force for the 25th anniversary of Citrus Expo.

Rick Kress, senior vice president of research commercialization for Southern Gardens Citrus will present a webinar titled “Can We Live Without Citrus?” on August 25 from 11:00 a.m. to 12:00 p.m. EDT. Can you imagine what your store would look like if the orange juice section was suddenly empty or produce shelves were void of all oranges, grapefruit, lemons and …
The federal Environmental Protection Agency (EPA) this week approved the temporary use of three bactericides on HLB-infected citrus trees. Florida citrus growers had already been using the products this year because Florida Commissioner of Agriculture Adam Putnam issued a crisis declaration allowing their use. Citrus Research and Development Foundation Chief Operations Officer Harold Browning announced the EPA decision at Citrus …
The University of Florida Institute of Food and Agricultural Sciences has added another soldier in its battle against citrus greening by hiring world-renowned entomologist Bryony Bonning. She has been named Eminent Scholar with tenure in the UF/IFAS entomology and nematology department. Currently, Bonning is a professor of entomology at Iowa State University and director of the National Science Foundation Center …
