A promising solution to HLB is advancing to Phase 2 field trials following research by a Central State University scientist in Ohio. Anthony Arment, a molecular biologist and professor of biology at Central State University, played a key role in early research and ongoing consultation for the project. Pop Test Oncology LLC, operating as Palisades Therapeutics, recently announced that its …
During the recent Florida Citrus Industry Annual Conference, Steven Hall provided an update on the Citrus Research and Field Trial (CRAFT) programs. Hall is executive director of the CRAFT Foundation. CRAFT programs have been very popular among growers to incentivize new plantings and build knowledge about HLB therapies like trunk injection, the use of individual protective covers, plant growth regulators …
By Lamiaa Mahmoud and Manjul Dutt Utilizing tolerant rootstocks to combat HLB is a long-term management strategy that can help sustain productivity and enhance tree survival, especially when implemented alongside other HLB management approaches. Australian limes are tolerant to HLB, and their DNA can be incorporated into HLB-susceptible citrus using conventional breeding methods to enhance tolerance to HLB. Over the …
By Randall P. Niedz and Michelle Heck Grove-First is a collaborative research initiative developed by U.S. Department of Agriculture Agricultural Research Service (USDA/ARS) scientists and partners to solve citrus greening (HLB) by evaluating potential treatments directly in the field. This direct-to-field strategy is based on the idea that only field testing can determine whether a treatment can rejuvenate HLB-infected trees …
This year marks the 25th anniversary of the Citrus Achievement Award. Most of those years, growers have been honored who have generational legacies in citrus. This year’s winner, too, comes from a citrus family. Ben Albritton is the 2025 Citrus Achievement Award winner. He says his family’s legacy and love for his fellow growers has him in it for the …
Fundecitrus researcher Renato Bassanezi recently emphasized the importance of controlling the psyllid that spreads huanglongbing (HLB, also known as citrus greening) in Brazil. Bassanezi pointed out that with the increase of HLB-spreading psyllids recorded in 2023 and the lack of eradication of diseased trees, controlling the HLB-spreading insect becomes increasingly important. The researcher said there can be no failures in …
Federal and state agriculture officials recently expanded the areas quarantined for huanglongbing (HLB, also known as citrus greening) disease in California. The quarantined area in the Foothill Ranch and Mission Viejo areas of Orange County has been expanded by 26.69 square miles, the Riverside area of Riverside County by 11.3 square miles, and the Valley Center area of San Diego …
The U.S. Department of Agriculture National Institute of Food and Agriculture (USDA/NIFA) announced May 28 it has invested nearly $23 million in 14 HLB projects in 2025. The projects seek to find solutions to combat and prevent HLB in citrus. The projects are part of the Emergency Citrus Disease Research and Extension Program. The University of Florida is the only …
Ching-Hong Yang, University of Wisconsin-Milwaukee (UWM) biological sciences professor, was recently awarded a $1.5 million federal grant to support research on a compound that suppresses HLB disease. His project is titled Bringing RejuAgro to Market: Development of a Groundbreaking Trunk Injection Biopesticide for Huanglongbing (HLB). The grant is from the U.S. Department of Agriculture National Institute of Food and Agriculture …
Carlton Collins recently was named top master’s researcher in the E. Broadus Browne Research Awards for Outstanding Graduate Student Research competition at the University of Georgia (UGA) College of Agricultural and Environmental Sciences. He was recognized for his research on huanglongbing (HLB) disease, also known as citrus greening. Collins, born in Jamaica, was introduced to citrus production on a small …
Texas A&M AgriLife Research scientists have developed an approach to countering the citrus disease HLB as well as zebra chip disease in potatoes and other vegetables. Their method uses spinach antimicrobial peptides, known as defensins, which naturally defend plants against a broad range of pathogens. Their study results were recently published in the Plant Biotechnology Journal. The effects show significant …
A research team led by Jian Ye from the Institute of Microbiology of the Chinese Academy of Sciences has identified the first mechanism of citrus resistance to HLB. Results of the study were published in Science. Utilizing artificial intelligence (AI), the team has also developed antimicrobial peptides that offer a promising therapeutic approach to combat the disease. This discovery addresses …
By Davie Kadyampakeni, Kondwani Kamsikiri and Alisheikh Atta Water scarcity is one of the major constraints in Florida citrus production systems, primarily due to erratic rainfall patterns and the low water- and nutrient-holding capacity of the predominantly sandy soils. The state’s soils contain more than 95% sand and have low organic matter (<1%) and very low water-holding capacity. These challenges …
Florida Foundation Seed Producers, Inc. (FFSP) has signed a licensing agreement with New Varieties Development and Management Corp. (NVDMC) to introduce new citrus varieties showing tolerance to HLB. The HLB-tolerant varieties covered by the agreement are: The collaboration also includes the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and the Florida Department of Citrus. It aims to …
By Fernando Alferez, Divya Aryal and Saoussen Ben Abdallah In the last few years, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus horticulture team at the Southwest Florida Research and Education Center (SWFREC) in Immokalee has performed several research trials in commercial farms and at the experimental farm at the SWFREC to elucidate the effect of …
The California Department of Food and Agriculture (CDFA) declared a citrus quarantine expansion in San Diego County’s Valley Center on March 26. The expansion occurred after detection of HLB disease in two citrus trees in residential neighborhoods in the Valley Center area during regular inspections. HLB is a major threat to San Diego County’s $144 million annual citrus crop …
By Tripti Vashisth and Prudhvi Vulchi To mitigate the effects of huanglongbing (HLB) on tree health and productivity, growers are encouraged to adopt proven horticultural practices. Based on recent field trials at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC), one effective approach combines frequent irrigation (FI), plant growth regulators (PGRs) …
Scientists with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and the U.S. Department of Agriculture Agricultural Research Service (USDA/ARS) recently wrote about efforts to identify HLB-affected versus healthy citrus fruit. UF/IFAS scientists are Mark Ritenour, Ketan Shende and Thomas Burks. Michelle Heck is with the USDA/ARS. A slightly edited version of their article follows: Most citrus …
Federal and state officials have expanded the quarantine for huanglongbing (HLB, also known as citrus greening disease) in the Mission Viejo area of California’s Orange County. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS), in cooperation with the California Department of Food and Agriculture, expanded the quarantine by 13.16 square miles. The expansion was in response …
By Fernando Alferez and Saoussen Ben Abdallah Individual protective covers (IPCs) are now being increasingly adopted in Florida to protect newly planted citrus trees from psyllid colonization. The risk of new citrus plantings becoming infected with HLB is especially high, as young trees flush more frequently and attract more psyllids. However, the adoption of IPCs does not occur in all …
