Asian citrus psyllids are detected sporadically in the San Joaquin Valley — home to most California oranges and mandarins — and are endemic in Southern California lemon country. But as far as anyone knows, the pests that spread HLB in Florida and Texas have not spread the disease into California’s commercial citrus groves. California HLB detections have been limited to 17 …
RUBIO, NELSON URGE SENATE LEADERS TO ADDRESS CITRUS GREENING IN TAX LEGISLATION LATER THIS YEAR (Washington, D.C.- July 21, 2016: News Release from office of Sen. Rubio) – U.S. Senators Marco Rubio (R-FL) and Bill Nelson (D-FL) today urged Senate leaders of both parties to make citrus greening a priority in tax legislation expected to be considered by Congress …
Florida citrus growers: 80 percent of trees infected by greening By: Brad Buck, 352-294-3303, bradbuck@ufl.edu Source: Ariel Singerman, 863-956- 8870, singerman@ufl.edu GAINESVILLE, Fla. — Florida’s citrus growers say as much as 90 percent of their acreage and 80 percent of their trees are infected by the deadly greening disease, which is making a huge dent in the state’s $10.7 billion …
By: R. W. Mankin, B. Rohde and S. McNeill The Asian citrus psyllid (ACP) is the primary vector of the devastating huanglongbing (HLB) disease of citrus. Efficient monitoring of ACP at low population densities is essential to conduct management programs with timely effectiveness for protection of Florida groves. Extensive research is being conducted to better understand ACP biology and behavior, …
Researchers share $4 million USDA grant to attack citrus greening From UF/IFAS: By: Kimberly Moore Wilmoth and Kathleen Haughney GAINESVILLE, Fla. — International researchers, including ones at the University of Florida and Florida State University, are sharing in a $4 million grant from the United States Department of Agriculture to attack the problem of citrus greening, a disease that has …
This spring, the seventh International Research Conference on Huanglongbing (IRCHLB) was held in Riverside, California. The inaugural event was held in 2008 and funded by a grant from the U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture. USDA researcher Tim Gottwald and University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor Jim Graham founded the …
By Jawwad Qureshi The Asian citrus psyllid (ACP, Figure 1) is the vector of huanglongbing (HLB) disease associated with the phloem-limited bacterium Candidatus Liberibacter asiaticus. Infected trees start to decline and produce poor-quality fruit, which drops prematurely. Consequently, citrus production has decreased dramatically since the advent of HLB in Florida in 2005. There is no cure for the disease yet. …
In the fall of 2022, five University of Florida researchers investigated Florida residents’ attitudes on HLB and Asian citrus psyllids (ACP) using online surveys over a 9-month period. The results of the study, Residents’ contribution to Asian citrus psyllid and citrus greening management in Florida residential habitats, was recently published in the Journal of Integrated Pest Management. Authors Romain Exilien, …
Tanishka Balaji Aglave of Valrico, Florida, received the $10,000 H. Robert Horvitz Prize for Fundamental Research for her investigation into a natural alternative treatment against citrus greening disease (known as huanglongbing, or HLB). Aglave, a 15-year-old who attends Strawberry Crest High School and grew up on a citrus farm, injected the trunks of infected citrus trees with an extract from …
By Jawwad Qureshi The Asian citrus psyllid (ACP, Figure 1) continues to feed on citrus trees infected with citrus greening and spread the disease to newly planted young trees. Therefore, it is not possible to produce a healthy citrus tree in an environment where citrus greening is endemic. Only the citrus under protective screen (CUPS, Figure 2) system allows the …
Agriculture officials and researchers in California have drastically reduced populations of HLB-spreading Asian citrus psyllids (ACP) through biocontrol measures. Now they’re working on ways to control other insects that are intent on protecting the ACP — Argentine ants. Mark Hoddle, professor of Extension in biological control at the University of California, Riverside, Department of Entomology, explained the ACP/Argentine ant dynamics …
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 …
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), …
By Christopher Vincent Particle film is a useful tool to take the edge off stress to citrus trees caused by weather and HLB. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research over the past several years shows moderate concentrations of kaolin particle films cause trees to grow faster, suffer less water loss and keep leaves cooler, even …
By Lauren Diepenbrock As the March bloom tapers off and fruit begin to set, it is time to think about lebbeck mealybug management to protect developing fruit. Damage to setting fruit causes malformed fruit that are often aborted or not marketable if they continue development (Figure 1). Early-season management is critical to both reducing early fruit damage and to maintaining …
The Christmas freeze event in 2022 affected some insect pests in the cold-hardy citrus region more so than others, according to Xavier Martini. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor spoke about his findings during the recent Citrus Health Forum held at the North Florida Research and Education Center (NFREC) in Quincy. Martini addressed …
California’s Citrus Research and Field Trials (CA-CRaFT) program is now accepting Cycle 2 applications from commercial growers. This initiative aims to showcase the efficacy of additional control measures against the Asian citrus psyllid (ACP). ACP is the carrier of the Candidatus Liberibacter asiaticus bacterium causing huanglongbing (HLB) disease in citrus. For Cycle 2, applications will be accepted until program capacity …
By Lauren Diepenbrock Insect and mite management is a year-round challenge in Florida citrus. With the warm climate, pests are at the ready as soon as plant resources are available to them. With knowledge of insect and mite biology in relation to tree phenology, plans can be developed to protect fruit and maintain productive citrus trees. Populations of some highly …
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, …
