A recent issue of the Annual Review of Phytopathology contains the article, “Management of huanglongbing of citrus: Lessons from São Paulo and Florida.” It discusses the lessons in HLB management, comparing what was done in orchards in Brazil’s state of São Paulo and in Florida. It also highlights the measures that worked and failed from the perspective of controlling the …
By Lukasz Stelinski, Eric Roldan and Kirsten Pelz-Stelinski Use of antibiotics in fruit production is not a new idea, but it has only recently been applied on a larger scale in Florida citrus. The initial labels for huanglongbing (HLB) treatment with antibiotics in Florida citrus were approved in March 2016 in response to significant economic losses caused by HLB. Antibiotics …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center hosted an OJ Break seminar in mid-May. Topics included management of nematodes, results of trunk-injection therapies and the use of cover crops in citrus. Larry Duncan, a UF/IFAS professor of nematology, presented research findings on the impact of sting nematodes in citrus. He provided …

As usual, the event was well organized and well attended. The agenda included topics such as: It was a value-packed day. HLB RECOMMENDATIONS Roger Smith of TreeSource Citrus Nursery in Woodlake, California, traveled quite a distance …
The impacts of kaolin and climate on HLB in Brazil were among topics addressed by researchers from Brazil’s Fundecitrus during the recent International Research Conference on HLB in Riverside, California. HLB is also known as citrus greening. Researcher Marcelo Miranda discussed results of a study on the use of processed kaolin in low doses to reduce the HLB-spreading psyllid population …
Fabrício Eustáquio Lanza, research coordinator at Brazil’s Cambuhy Agricola, recently told how his company has kept HLB at low and economically acceptable incidence levels. His presentation at the recent International Research Conference on HLB was based on a report he co-authored with Alexandre Tachibana, Ivan Brandimarte, Antonio Juliano Ayres and Renato Beozzo Bassanezi. The report follows: MANAGEMENT MEASURES Huanglongbing (HLB), …
BRAZILIAN RESEARCH RESULTS IN A UNIQUE PRODUCT FOR HLB MANAGEMENT A groundbreaking study recently conducted by renowned Brazilian agro-science has resulted in a formula for the effective management of citrus greening, a disease that has severely affected citriculture in Brazil and worldwide for a long time. It was in the laboratories of the Citrus Center of the Agronomic Institute of …
The University of Georgia’s (UGA) Plant Molecular Diagnostic Laboratory (MDL) on the Tifton campus is a U.S. Department of Agriculture-certified lab performing huanglongbing (HLB, also known as citrus greening) testing. It offers the advanced test to commercial growers, homeowners, nurseries, Extension and research personnel and the Georgia Department of Agriculture. The molecular test per sample costs $80. Candidatus Liberibacter species associated with HLB …
Federal and state agriculture officials have expanded the areas quarantined for huanglongbing (HLB; also known as citrus greening) in California. The action was taken by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) in cooperation with the California Department of Food and Agriculture (CDFA). APHIS is adding portions of Los Angeles, San Diego and Ventura counties …
The dream of citrus varieties being totally resistant to huanglongbing (HLB) disease (citrus greening) is still a distant reality for Florida growers. For now, they must depend on tolerant varieties to lessen the disease’s impact, which is widespread throughout most of the state. Michael Rogers, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center …
One California citrus leader believes Georgia should respond more aggressively to huanglongbing (HLB, also known as citrus greening) for the sake of the industry’s future in the state. Roger Smith, fourth-generation citrus producer and executive of AC Foods, spoke during the recent Georgia Citrus Association meeting in Tifton. He discussed the disease that devastated citrus production in Florida and could …
It’s one thing for a hybrid citrus tree to tolerate HLB, but quite another thing for it to produce orange-like fruit that makes delicious orange juice (OJ). That holy grail of traits could be nearer, thanks to a team of U.S. Department of Agriculture Agricultural Research Service (USDA-ARS) and University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientists. …
Living with huanglongbing (HLB) disease (citrus greening) is a much different process for citrus growers than protecting their crop from it. Growers in the cold-hardy citrus region are currently trying to keep the devastating disease out of their area. Industry experts like Michael Rogers, University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center director, are …
By Tripti Vashisth and Mary Sutton Prolonged water deficits can negatively impact flowering, fruit growth, crop load and fruit quality. Unfortunately, HLB-affected trees are more susceptible to water deficits than healthy trees due to extensive root loss. Observing HLB-affected trees throughout the dry season showed that severely symptomatic trees consistently had lower leaf water potential than mildly symptomatic trees. This …
You’ve probably heard the term CRISPR in recent years. It is a relatively new breakthrough in science that has applications in human health and even in the fight against HLB. Nian Wang, a professor of microbiology and cell science with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), has been on the forefront of CRISPR research. Here …
Using the plant growth regulators (PGRs) cytokinin in spring, gibberellic acid (GA) in summer and 2,4-D in late fall can be helpful for HLB-affected trees, horticulturist Tripti Vashisth reported. Her PGR update came during a Feb. 21 OJ Break. Multi-county citrus Extension agent Chris Oswalt hosted the event at the University of Florida Institute of Food and Agricultural Sciences Citrus …
By Frank Giles The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has established itself as a leader in new technological frontiers like artificial intelligence (AI). In fact, the school has the 15th most powerful computer in the world. The HiPerGator, as the computer is called, will assist in AI development and on many other technological fronts. Another …
The effort to help huanglongbing (HLB)-impacted citrus trees has taken another step forward. A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) study examined the relationship between fertilization, root health and fruit yield. Researchers focused on Valencia orange trees with HLB. Associate Professor Davie Kadyampakeni led the effort at the UF/IFAS Citrus Research and Education Center. The study, …
Federal agriculture officials, in cooperation with Louisiana agriculture officials, have established a federal quarantine area for huanglongbing (HLB; citrus greening), caused by Candidatus Liberibacter asiaticus, in all of Saint Charles Parish in Louisiana. The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA APHIS) took the action in cooperation with the Louisiana Department of Agriculture and Forestry (LDAF). …
Mexico’s Ministry of Agriculture and Rural Development recently pointed out ways the country has successfully dealt with huanglongbing (HLB), the most devastating disease of citrus worldwide. The ministry reported that the disease has triggered socioeconomic problems in other citrus-producing countries and regions in the Americas, Africa and Asia. “With appropriate agronomic-phytosanitary management, the life of affected trees can be prolonged, …
