On Jan. 1, 2018, the California Department of Food and Agriculture (CDFA) implemented an emergency regional quarantine to more effectively protect California citrus from huanglongbing (HLB) disease. The quarantine created seven zones: 1) counties where HLB has not been detected and are not next to citrus-producing counties or the Mexican border; 2, 3 and 4) counties widely infested with ACP …
At the International Citrus Business Conference, speakers will discuss strategic issues that concern the citrus industry, including HLB, juice production and how markets around the world compare to one another. Chris Stone, of Winter Haven, Florida, will be speaking at the conference about the impact that HLB has on prices and availability of cold-pressed citrus oils. Stone said he has …
The 2018 International Citrus Business Conference will be a meeting to tackle the pressing issues facing the citrus industry, including the rapid decline of citrus juice markets. Allen Morris, of Morris Agribusiness Services, says the citrus industry has lost 50 percent of the U.S. orange juice market since 2002. The industry continues to decline at a swift 5 to 7 …
Researchers are trying to use all available tools to control HLB-spreading psyllids, says entomologist Michael Rogers with the University of Florida Institute of Food and Agricultural Sciences. Rogers, director of the Citrus Research and Education Center in Lake Alfred, says scientists want “to show that we can actually grow citrus in the age of HLB and still be profitable.” “The …
Economist Tom Spreen thinks advanced production systems (APS) and citrus under protective screen (CUPS) offer hope for some growers in the face of HLB. Spreen, a University of Florida Institute of Food and Agricultural Sciences professor emeritus, discussed APS and CUPS at a recent Gulf Citrus Growers Association economic seminar in LaBelle. Spreen says growing with APS “means you have …
University of California Riverside (UCR) is committed to a major offensive against huanglongbing (HLB, or citrus greening disease), as the threat is marching ever closer to commercial citrus orchards in California. The only confirmed cases in Southern California have been in residential trees in Los Angeles and Orange counties, including near the UCR campus. But some experts believe it is …
A proposal aimed at helping citrus growers replant after Hurricane Irma is included in a federal tax overhaul that could be approved this week by Congress, U.S. Rep. Vern Buchanan, R-Fla., said Monday. The proposal, sponsored by Buchanan and backed by Florida’s congressional delegation, would provide tax incentives for farmers who cannot afford to replace trees damaged by the storm …
Grafted orange trees showcased at the 100th anniversary of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) may give the state’s citrus growers new reason to hope the industry can cope with the citrus greening crisis, UF/IFAS researchers say. University of Florida scientists and Tropicana are teaming up to test promising new UF/IFAS-bred …
A citrus nursery employee has found super-root mutants that might offer hope for developing trees that are less susceptible to HLB. The employee is Beth Lamb, a tissue culture expert at Phillip Rucks Citrus Nursery. University of Florida Institute of Food and Agricultural Sciences citrus breeder Jude Grosser tells about her discovery. “She discovered some mutants of some of the …
By Jim Gravley The entire citrus industry has changed since the arrival of HLB (citrus greening). To ensure success and produce a quality product, the grower must adapt and truly understand the issues brought on from the infection of HLB. The disease was officially identified in 2005 in South Florida, and we are still fighting to save this great industry. …
University of Florida Institute of Food and Agricultural Sciences entomologist Jawwad Qureshi discussed several means of Asian citrus psyllid control at Citrus Expo in August. He provides an overview of his presentation. Qureshi says it is best to start psyllid sprays during the winter dormant period. “Do it individually or do it in a collaborative effort, but you must do …
By: Brad Buck, 352-294-3303, bradbuck@ufl.edu GAINESVILLE, Fla. — Grapefruit grows better under screen houses than in unprotected groves because the indoor facilities keep out the insect that causes citrus greening, new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research shows. Protecting citrus from greening is essential, UF/IFAS researchers say. The disease, first detected in Florida in 2004, …
Two economists addressing a Gulf Citrus Growers Association economic seminar on Nov. 30 agreed that low-density citrus plantings would likely be hazardous to growers’ financial health in the face of HLB. One also reported that the average grower is not making a profit, and that small growers are exiting the industry faster than larger growers. “We were looking into different …
Walls consisting of insect-proof screen held up by telephone poles hold promise for helping growers reduce the cost of controlling HLB-spreading psyllids. The walls serve as artificial windbreaks in a new model grove planted in June at the Citrus Research and Education Center (CREC). The grove was one of numerous projects viewed by more than 500 attendees who came to …
An approximately 35-acre research plot that fell victim to citrus canker years ago will soon become a new research site helping growers pick trees that fare best with HLB. The plot at the Indian River Research and Education Center (IRREC) in Fort Pierce will keep its former name, the Millennium Block. University of Florida Institute of Food and Agricultural Sciences …
By Arnold Schumann, Laura Waldo, Alan Wright and Rhuanito Ferrarezi Authors’ note: This article was written before Hurricane Irma passed through Florida. We are still assessing the full impact and implications of storm damage to both University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus undercover production systems (CUPS) facilities and will provide updates in future articles. Citrus …
In an interview at the Citrus Research Board’s (CRB) annual conference last month, Karen Ross, secretary of the California Department of Food and Agriculture (CDFA), said the present status of huanglongbing (HLB) disease is similar to another disease that challenged the California citrus industry years ago. Pierce’s disease was a potentially devastating threat long before HLB. “One of the things …
The long-time project manager for the Citrus Research and Development Foundation (CRDF) says the group formed to find solutions to HLB has done the best it can. Tom Turpen with Technology Innovation Group was recently honored for his service, which is being curtailed. Turpen actually began work with CRDF’s predecessor, the Florida Citrus Production Research Advisory Council, soon after HLB …
At Citrus Expo, Aaron Himrod of Himrod Citrus Nursery made the case for replanting citrus trees lost to HLB and other causes. “I think growers need to replant because we are having some success with young trees that we’re not having with older trees,” Himrod said. “The young trees are responding a lot better to our treatments. And we …
