Recently, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) reported research on the development of a new type of citrus tree that can fight off the HLB-spreading Asian citrus psyllid (ACP). The genetically modified tree has only been tested in the lab and the greenhouse, but the research looks promising. The approach involves inserting a gene into …
The citrus section in the February issue of Specialty Crop Grower is coming soon. It’s full of features for growers to dive into. First up is part two of results from the Florida Citrus State of the Industry Survey. (See part one here.) Learn out what percent of growers say they are replanting and how many are participating in the …
Scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are testing a new type of citrus tree that can fight off the HLB-spreading Asian citrus psyllid (ACP). The genetically modified tree has only been tested in the lab and the greenhouse but is very promising as a potential solution to HLB. The approach involves inserting a …
Australia’s New South Wales (NSW) Government has partnered with the Australian Centre for International Agricultural Research and Hort Innovation to prepare the citrus industry against huanglongbing (HLB). Although widespread in Asia and found in North and South America, HLB is not known to be present in Australia. The psyllid that spreads HLB is also absent from Australia. A collaborative research …
The California Department of Food and Agriculture (CDFA) has confirmed the detection of the citrus plant disease huanglongbing (HLB) in inactive citrus acreage in the city of Yorba Linda, Orange County. The detections mark the first time HLB has been confirmed in plant samples on non-residential, non-nursery citrus acreage. The detection site, which is not currently operational or being cultivated …
The November issue of Citrus Industry magazine features some of the faces of Georgia’s citrus industry. The cover story is a profile of citrus grower Lindy Savelle. She didn’t grow up in the citrus industry, and farming was not her first career. But her unconventional path has led her to become a leader in Georgia’s emerging citrus industry. Savelle serves …
Fundecitrus researchers Marcelo Miranda and Wellington Ivo Eduardo participated in the recent XXIX Brazilian Congress of Entomology in Uberlândia in the state of Minas Gerais. In a round table discussion on fruit plant pests, Miranda addressed the challenges of implementing integrated pest management in citrus for insect vectors of pathogens. This includes the leafhopper that transmits citrus variegated chlorosis and …
Regular scouting for Asian citrus psyllids and citrus greening disease is critical for Georgia’s citrus industry to remain healthy. That advice applies to both commercial growers and homeowners, Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist, said during the recent Citrus Grower’s Summer Update meeting in Valdosta. Oliver encouraged all growers to scout for the disease …
The area quarantined for HLB in San Diego County, California, has been expanded, the U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) announced on Sept. 23. USDA APHIS took the action in cooperation with the California Department of Food and Agriculture (CDFA). HLB, a plant disease caused by Candidatus Liberibacter asiaticus, is also known as citrus …
Organic citrus growing presents unique hurdles in Florida, Texas and other southern states. Poor soil quality, nutrient deficiencies and a limited range of pest control options plague organic production. But the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Davie Kadyampakeni is poised to transform the future of organic citrus growing. He aims to do that with a …
U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA/APHIS) officials, in cooperation with the California Department of Food and Agriculture (CDFA), recently expanded the areas quarantined for huanglongbing (HLB) and sweet orange scab (SOS) in the state. HLB The quarantined area in Los Angeles, Orange and Riverside counties has been expanded by approximately 50 square miles. Additionally, the …
One of Georgia citrus growers’ worst fears is slowly becoming a reality. Citrus greening, also known as huanglongbing (HLB), was observed in a Georgia commercial citrus grove for the first time in 2023. This is alarming news for the industry, says Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist. “We knew HLB was here in residential …
The U.S. Department of Agriculture Agricultural Marketing Service (USDA AMS) Specialty Crop Block Grant Program awarded 54 grants and 524 sub-award projects totaling $72.9 million for fiscal year 2024. The following citrus projects were included in the funding. CALIFORNIA The California Department of Food and Agriculture (CDFA) received a grant for $448,742 for mitigating huanglongbing (HLB) in citrus using naturally-derived …
In Brazil, a more effective and sustainable insecticide for HLB-spreading psyllids was developed by Embrapa (Brazilian Agricultural Research Company) in partnership with the Institute of Chemistry of the State University of Campinas (Unicamp). The work resulted in a controlled-release system of the insecticide thiamethoxam molecule. Encapsulation was performed in polymeric nanoparticles, structures more than 80,000 times smaller than the thickness …
The U.S. Department of Agriculture National Institute of Food and Agriculture (USDA/NIFA) has invested more than $250 million to find a solution for HLB. One example of USDA NIFA-funded research is citrus under protective screen (CUPS). University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientist Arnold Schumann and colleagues began testing CUPS at the Citrus Research and Education Center …
Georgia’s citrus industry has a new leading lady. Actually, she’s a familiar face who has a new title. While Lindy Savelle will continue to promote Georgia citrus, it will be under the title of executive director of the Georgia Citrus Association (GCA).

An adult Asian citrus psyllid (ACP) sample from a residential property in the San Jacinto Valley area of Riverside County, California, has tested positive for Candidatus Liberibacter asiaticus (CLas), the bacterium that causes huanglongbing (HLB). The positive sample was collected as part of the Multi-Pest Risk Survey on a residential property in Hemet. It was confirmed positive for CLas on …
A study by researchers from the Guangdong Academy of Agricultural Sciences and South China Agricultural University sheds light on the genetic mechanisms that can defend against Asian citrus psyllid (ACP) infestation. ACP is the vector for HLB, the most devastating disease of citrus. The study was published in Horticulture Research on April 1. It unveils the roles of two cytochrome …
Repeated evaluations throughout California showed “a massive decline – greater than 70%” in HLB-spreading Asian citrus psyllid (ACP) densities since the inception of a biological control program, a researcher reported recently. Mark Hoddle said the University of California, Riverside (UCR) and the California Department of Food and Agriculture (CDFA) turned to biocontrol because insecticide spraying wasn’t adequately controlling the psyllid. …
