Nian Wang, a University of Florida (UF) Institute of Food and Agricultural Sciences professor, has been awarded one of the school’s 2022 Inventions of the Year for his work on HLB. Wang works in the Microbiology and Cell Science Department at the Citrus Research and Education Center. He worked on controlling HLB by mitigating cell death of the phloem tissues …
By Kirsten S. Pelz-Stelinski and Lukasz L. Stelinski Managing Asian citrus psyllids (ACP) remains a consideration for growers because psyllids transmit the citrus greening disease pathogen, Candidatus Liberibacter asiaticus (CLas), to newly planted trees. There are several tools that can reduce psyllid populations or mitigate the symptoms of HLB and improve the health of infected trees. However, additional methods that …
What may be the closest thing yet to a timely silver bullet for HLB was discussed Oct. 26 at Lake Alfred’s Citrus Research and Education Center. Josh Steinbronn, director of research and development at TJ BioTech, said trunk injection of his company’s ReMedium TI oxytetracycline product suppresses Candidatus Liberibacter asiaticus (CLas), the causal agent of HLB. He added that injection …
B9-65 Valencia received much attention from horticulturist John Chater during a virtual meeting highlighting HLB-tolerant citrus varieties developed by the Citrus Research and Education Center (CREC) Plant Improvement Team. Chater is an assistant professor at the University of Florida Institute of Food and Agricultural Sciences CREC. ORANGESAccording to Chater, pound solids per acre and yield per acre are the most …
Conclusive data on trials in the Millennium Block, expected in early 2023, may reveal which of more than 5,500 trees can tolerate HLB, researchers say. The Millennium Block is at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC) in Fort Pierce. IRREC Director Ronald Cave said the 20-acre grove, established …
A team of researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has successfully identified the CsDMR6 gene, which impacts a citrus tree’s reaction to the citrus canker pathogen. Zhanao Deng and Fred Gmitter, both professors and plant breeders, are members of that team. By editing the CsDMR6 gene in the plant’s DNA to interfere with …
The average incidence of HLB rose from 22.37% in 2021 to 24.42% in 2022 in Brazil’s citrus belt, an annual survey by Fundecitrus shows. That’s an increase of 9.16%. In the regions of Brotas, Limeira and Porto Ferreira, where the incidence was already high in previous years, HLB increased to even more worrying levels of 49.41%, 70.72% and 74.05%, respectively. …
Florida Citrus Mutual (FCM) has been working with product registrants to gather industry support for two 24(c) label requests being presented to the Florida Department of Agriculture and Consumer Services (FDACS). REMEDIUM TIThe first request, from TJ BioTech, is related to the use of ReMedium TI via injection in citrus trees suffering from citrus greening. Research has proven oxytetracycline injection …
Rick Dantzler, chief operating officer of the Citrus Research and Development Foundation (CRDF), spoke during the general session of the Citrus & Specialty Crop Expo. He provided an update on products he hopes will help the citrus industry reset and begin to increase production again. The products are two oxytetracycline (OTC) materials that can be injected into citrus trees. “We …
By Tripti Vashisth and Mary Sutton Citrus trees affected by huanglongbing (HLB) consistently have small fruit and low fruit numbers at harvest. The low fruit numbers are largely attributed to the increased rates of preharvest fruit drop that accompany HLB. Small fruit is more likely to drop during this preharvest period, suggesting a link between fruit size and retention. To …
The recent Florida Citrus Industry Annual Conference featured educational presentations on navigating production in an environment where HLB is endemic in groves. Two of those presentations focused on new technology being developed for use in citrus. Two companies, Elemental Enzymes and TJ BioTech, have been collaborating with the Citrus Research and Development Foundation (CRDF) to research their respective products’ potential …
Microregion maps developed by Fundecitrus should help Brazilian citrus growers make the necessary decisions to combat HLB disease, also known as greening. Fundecitrus explained that the incidence of HLB differs in the various regions of Brazil’s extensive citrus belt. To allow citrus growers to better understand the places where the disease is located, a study by Fundecitrus divided the belt …
The pros of injecting the antibiotic oxytetracycline (OTC) into citrus tree trunks to combat HLB appear to be numerous, including increased fruit yield, according to scientist Ute Albrecht. On the other hand, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher only discussed one con, but it was a big one. “Trunk injections cause injury, and long-term …
University of Florida Institute of Food and Agricultural Sciences researcher Nian Wang reported in a July 20 webinar that HLB is a pathogen-triggered immune disease. After explaining the sequence in which the disease attacks trees, he suggested ways growers can use that knowledge to combat HLB. Wang is a microbiologist and cell scientist at the Citrus Research and Education Center. …
By Jude Grosser, Manjul Dutt and Fred Gmitter Exploiting citrus genetic diversity is the key to defeating HLB. Plant species have survived for millennia with evolving, hostile pathogens. This is possible through natural selection within genetically diverse populations. Tolerant or resistant individuals survive and intermate, get through the bottleneck, and the species evolves. Current citriculture is based on extremely limited …
The goal of an expedited tree propagation program is to have several million HLB-tolerant or HLB-resistant trees planted in the next several years. Greg Hodges, assistant director of the Florida Department of Agriculture’s Division of Plant Industry (DPI), said he believes that goal is attainable. Hodges and others presented the propagation plans to the Florida Citrus Commission (FCC) on July …
Federal and state officials in late June expanded the areas quarantined for huanglongbing (HLB, also known as citrus greening), caused by Candidatus Liberibacter asiaticus, in California. The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) took the action in cooperation with the California Department of Food and Agriculture (CDFA). APHIS added portions of Los Angeles, Orange, Riverside …
By Christopher Vincent Kaolin particle film is a non-toxic tool to reduce psyllids and increase tree growth. Particle films are nothing more than a suspension of solid particles that make a “film” on the leaves after they dry. They work mostly by reflecting light. Kaolin is the most common type of particle film because the clay is mined directly and …
California’s commercial citrus groves remain free of HLB disease 14 years after Asian citrus psyllids (ACP) were first detected there. The state’s Citrus Pest and Disease Prevention Program (CPDPP) described that as “no small feat” in its recently released 2020-21 annual report. “The past fiscal year presented its fair share of headwinds for citrus-growing operations,” the report stated. “From pandemic-induced …
Brazil’s Fundecitrus reported that the exchange of international researchers and technicians working on the PRE-HLB (Preventing HLB Epidemics for Ensuring Citrus Survival in Europe) project strengthens research on the disease. In recent months, Fundecitrus received a researcher from the University of Amsterdam (Netherlands) and sent a researcher to the University of Valencia (Spain). Counting on the expertise of more than …
