Citrus Extension agent Steve Futch answers questions following a grower forum in Arcadia on October 27. Growers discussed production, bactericides for HLB and much more. The forum opened with one grower saying he doesn’t know how much longer he can keep going. Another reported per-acre orange production of 450 to 500 boxes in some blocks – a superb level in …
Another early-detection method being developed works by smelling huanglongbing infections in trees. This method detects the different scents plants give off. Researchers at the University of California, Davis have created a test that could lead to advances in fighting huanglongbing (HLB) disease in citrus. Researcher and professor of mechanical and aerospace engineering, Christina Davis, said the test looks for a …
Another early detection and screening process for HLB has been developed at the University of California, Davis. Cristina Davis, professor of mechanical and aerospace engineering, is using volatile organic compounds (VOCs) as indicators of disease in trees. VOCs are odors that are emitted by all living things. These odors can be very meaningful, because they are distinctively different between a …
HLB pre-screening through analyzing plant metabolism holds potential to be a relatively inexpensive option for growers. Caroline Slupsky, professor in the Department of Nutrition and Food Science and the Department of Technology at the University of California, Davis, is looking at the metabolism of citrus trees and analyzing changes as indicators of stress and disease. Plants’ metabolic pathways change in …
By Reza Ehsani, Megan Dewdney and Evan Johnson In the last two years, many growers looked at thermotherapy as a way of keeping HLB-affected citrus trees in production until a more permanent solution could be developed. It has been shown that thermotherapy can kill HLB-causing bacteria under controlled environments. But the exact time and temperature is not known, and it …
Citrus grower Paul Fabry discusses grove practices that led to a huge increase in production in a newly acquired Basinger grove in just a few seasons. The grove has approximately 750 net acres. “Two years ago when we first got the grove, it was in a shape that needed some renovation and I was advised by several prominent industry leaders …
University of Florida researcher Jude Grosser focused on root nutrition during the Citrus Nutrition Day at the Citrus Research and Education Center on October 11. In this report, he says citrus roots impacted by HLB are missing the nutrients they need and discusses possible solutions, including what he calls “hybrid nutrition programs.” “We’ve gotten kind of too focused on what’s …
Timing of fungicide sprays is the key to controlling the postbloom fruit drop (PFD) that caused many Florida citrus growers severe problems this year. That was a central message that University of Florida researcher Natalia Peres delivered at Citrus Expo this summer. In this interview, Peres discusses the keys to proper spray timing, starting with bloom. Peres says longer bloom …
Canker and HLB have made things very difficult for Indian River citrus growers, but outgoing Indian River Citrus League President Scott Lambeth is optimistic about bactericides. “For the last three years with the contraction of the industry, it’s very difficult to keep an open mind and stay positive when you see family farms that are third and fourth generation still …
Southwest Florida citrus growers are now spending about $2,327 per acre to grow oranges, University of Florida economist Ariel Singerman said in a Citrus Expo presentation in August. “This is a decrease in cost of about 4 percent compared to last year,” Singerman says in this report. He explains the reason for the production cost decrease: “It is no longer …
“We’re an industry who’s a group of fighters,” Florida Commissioner of Agriculture Adam Putnam says in summarizing his talk Friday at the Indian River Citrus League’s annual meeting in Vero Beach. “With all the challenges that we’ve seen here on the River – from canker to hurricanes and the devastation caused by greening – we’re still blocking and tackling and …
Grower Joe Davis Jr., a panelist at a Peace River Valley Citrus Growers Association gathering Thursday, says he expects a Florida orange crop of 61 to 70 million boxes this season. Last season’s Florida orange crop was 81.5 million boxes. “Our groves are down,” Davis says. “We’re guessing that earlies and mids will probably be down about 10 percent, and …
Six citrus growers shared their views on a wide range of topics with about 50 fellow producers at a Peace River Valley Citrus Growers Association (PRVCGA) gathering Thursday in Bowling Green. PRVCGA Executive Director LeAnna Himrod, who posed questions for the panelists, summarizes the discussions by topic. Crop size: “I think that everyone’s expecting it to be lower than last …
Citrus growers sometimes ask University of Florida entomologist Phil Stansly why they should continue to spray for HLB-spreading psyllids when trees are already infected with the disease. Stansly answered that question at Citrus Expo in August. “There are two issues with HLB,” Stansly says in this interview with Tacy Callies summarizing his Expo presentation. “One is incidence. In other words, …
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, …
