Hurricanes, development, demographics, disease and other issues combined in recent decades to severely reduce citrus acreage and crops in Plaquemines Parish, which has the majority of Louisiana growers. According to Louisiana State University (LSU) AgCenter, the state has only 841 acres of citrus remaining. Anna Timmerman, LSU AgCenter horticultural Extension agent, discussed the industry’s woes in the parish that she …
A citrus tree at a private residence near San Diego, California, has been found to be infected by four Asian citrus psyllids (ACP). Upon testing, the ACP were found to be carriers of the bacterium that causes citrus greening, also known as huanglongbing (HLB). The finding was announced by the California Department of Food and Agriculture’s Citrus Pest and Disease …
UC Riverside scientists are working to breed new fruits that are naturally resistant to huanglongbing (HLB). The hybrid fruits will ideally share the best of their parents’ attributes: the tastiness of citrus and the HLB resistance displayed by some Australian relatives of citrus. HLB, also called citrus greening disease, has been detected in California, where 80 percent of the country’s …
One obvious symptom of HLB is leaf chlorosis — yellow blotches appearing on otherwise dark green citrus leaves. Although chlorosis can indicate other health issues, in trees affected by HLB, it’s thought to be triggered by the underlying bacterial infection causing the disease. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant pathologist Nabil Killiny conducted a study …
By Ruth Borger It is time for a new year, and many of us cannot see 2020 end fast enough. It is almost time for 2021, and there is a lot to be hopeful for. New vaccines to fight the coronavirus hold great potential for beating the pandemic. U.S. citrus sales so far this season continue to show strong performance. …
A company that recently obtained a patent for a natural peptide solution to treat HLB has received Citrus Research and Development Foundation (CRDF) funding to see if the product has efficacy for other citrus diseases. CRDF will fund the company, Elemental Enzymes, for about $61,200, said CRDF Chief Operating Officer Rick Dantzler. Elemental Enzymes proposes to do research “to see …

Putnam of Memphis, Tennessee; and Steven D. “Steve” Sorrells of Arcadia, Florida. They will be inducted during a luncheon tentatively scheduled for Nov. 5 at Florida Southern College …
Amit Levy with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) describes research he’s conducting into the way the causal agent of HLB interacts with a citrus tree. The causal agent is the bacterium Candidatus Liberibacter asiaticus (CLas). Levy, whose research is funded by a U.S. Department of Agriculture grant, says CLas is found in a citrus …
Although COVID-19 whacked away-from-home sales at hotels, restaurants and the like in 2019-20, Florida’s Natural posted record net sales and its growers received strong returns on their fruit. “Our results were better than expected,” said Frank Hunt III, chairman of the nation’s third largest orange juice producer. Chief Financial Officer Chip Hendry pegged the cooperative’s historical high net sales at …
Texas A&M AgriLife Research scientists have made a discovery that should help combat fastidious or “unculturable” pathogens, such as Candidatus Liberibacter asiaticus, the HLB causal agent. HLB is also known as citrus greening disease. Kranthi Mandadi, a researcher with Texas A&M, and his colleagues have been working several years on developing new technologies to fight the fastidious pathogens. Mandadi and …
Several University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) faculty are collaborating with other universities and organizations on research, especially for HLB. Michael Rogers, director of the UF/IFAS Citrus Research and Education Center (CREC), summarizes the work they are doing on a variety of grant-funded projects. Rogers starts with a U.S. Department of Agriculture (USDA)-funded project led by …
California Citrus Mutual (CCM), Florida Citrus Mutual and Texas Citrus Mutual have voiced their support that California Congressman Jim Costa (D-Fresno) be appointed as the new chair of the House Agriculture Committee.

The ability to adapt is essential in growing citrus. John Gose, the cover story subject in the December issue of Citrus Industry magazine, knows this to be true. With nearly 40 years of citrus-growing experience at Lykes Bros., Gose has had to adapt to many changes during his career. Learn how he is adapting to citrus greening and the contributions …
By Ruth Borger Despite 2020 being a challenging year with a lot to complain about, there are many things to be thankful for. This is the time of year to take a few minutes to reflect on what we have to be grateful for. Here are just a few things to be thankful for that come quickly to mind. A …
In 2016, federal authorities began allowing Florida citrus growers to spray oxytetracycline solutions on their trees to combat citrus greening disease. Since then, researchers have been investigating oxytetracycline delivery methods. In a Citrus Expo presentation, Christopher Vincent, assistant professor of horticultural sciences at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center, shared …
Four researchers from around the country summarized their work on culturing the causal agent of HLB and agreed to consider a large, joint culturing project. The Citrus Research and Development Foundation (CRDF) hosted the panel discussion on Nov. 5 about culturing Candidatus Liberibacter asiaticus (CLas). CRDF organized the presentation after receiving a request for funding of a CLas culturing project …
To the surprise and consternation of growers and officials, 74 Asian citrus psyllids (ACP) have been discovered in Kern County, California, since June. Local and state officials are concerned about the recent uptick in trappings and are working to find how extensively the infestation has spread. The trappings have been equally dispersed in residential and commercial citrus. Staff from the …
Citrus growers told Environmental Protection Agency (EPA) officials why they want the insecticide aldicarb registered for use in Florida citrus, and discussed their problems with citrus greening. EPA cancelled the use of Temik, the Bayer brand name for aldicarb, on citrus at the end of 2011. Mike Aerts of the Florida Fruit & Vegetable Association (FFVA) said the Oct. 22 …
Three teams of scientists from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recently received nearly $4.5 million in U.S. Department of Agriculture (USDA) funds to study new ways to manage HLB.
