Two short videos about HLB-related research were available at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) booth at Citrus Expo in August. The videos are available online for viewing. UF/IFAS researcher Tripti Vashisth narrated the video, HLB-Associated Preharvest Fruit Drop. She said up to 40% of fruit can drop from mildly HLB-symptomatic trees shortly before harvest, …
A Florida citrus grower and a Florida citrus researcher were quoted extensively in a recent Australia Broadcasting Corporation TV show about HLB. Grower Kyle Story and University of Florida Institute of Food and Agricultural Sciences plant pathologist Megan Dewdney appeared in an approximately 12-minute segment of the show Landline. The segment’s focus was Australia’s effort to keep HLB out of …

Private consultant Elizabeth Steger on Aug. 16 forecast Florida will produce 52 million boxes of oranges in the 2021-22 season — 1.5% less than the 52.8 million boxes produced in 2020-21. Steger projected 20.8 million boxes of early-midseason oranges; that’s less than the 22.7 million boxes produced last season. Her Valencia projection is 31.2 million boxes; that’s more than the …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is asking Florida fresh citrus growers and packers to complete a brief, anonymous survey about a disorder some call “greasy green.” The symptoms of the disorder are consistent with greasy spot, but a direct causal relationship has not been proven. The disorder may also be related to other possible …
Codex DNA, Inc. has announced a collaboration with researchers from several organizations to identify scalable therapeutic measures against HLB. The multidisciplinary team has been awarded a grant worth nearly $15 million from the National Institute of Food and Agriculture (NIFA) to develop cost-effective and sustainable solutions to the disease. Other collaborators include the U.S. Department of Agriculture’s (USDA) Agricultural Research …
Plant breeding, project terminations and peptide discussions dominated the July 27 meeting of the Citrus Research and Development Foundation’s (CRDF) board of directors. CRDF Chief Operating Officer Rick Dantzler provided the following report: PLANT BREEDINGWe continue to believe that plant breeding will ultimately be how we put HLB in the rearview mirror. As a result, we continue to put a …
Scientist Sarah Strauss has learned some interesting and promising things about the use of cover crops in Southwest Florida citrus over the past 2.5 years. But the University of Florida Institute of Food and Agricultural Sciences researcher has not yet found that cover crops provide what growers seek most — increased yields. Use of the crops has also not yet …

The projected crop is 9.51% larger than the previous crop of 268.63 million boxes, but is still 10.53% lower than the …
Penn State and U.S. Department of Agriculture (USDA) scientists have used cutting-edge CRISPR/Cas technology to develop a diagnostic test that could enable early diagnosis of huanglongbing (HLB). In a study newly published in the journal Phytopathology, the researchers demonstrated that the new test can detect the presence of the HLB causal agent — the bacterium Candidatus Liberibacter asiaticus (CLas) — …
Two growers expressed different views about the recent decision to deny the use of the pesticide aldicarb in Florida citrus. The denial was made by the Florida Department of Agriculture and Consumer Services (FDACS). One termed the decision “disappointing.” The other referred to it as a “a blessing.” “It is disappointing to lose any tool that would strengthen our existing …
Citrus Research and Development Foundation (CRDF) directors on March 23 voted to request research proposals from scientists in nine topic areas for the coming year. The nine areas, mostly focusing on HLB, are: Understanding the mechanisms for increasing fruit retention in HLB trees by manipulating hormonal balance in the fruit and the tree or by altering the relationship between vegetative …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus researchers are collaborating on ground-breaking research projects to fight against HLB. They are working with researchers at the University of California-Riverside (UC-Riverside), Texas A&M and Washington State University on a project to field-test new citrus cultivars for tolerance or resistance to HLB. The research is funded by the U.S. …
Citrus Research and Development Foundation (CRDF) Chief Operating Officer Rick Dantzler on Feb. 23 detailed CRDF spending on efforts to solve HLB. According to Dantzler, the Florida-based organization spent $140.7 million between its formation in 2009 and 2020. The vast majority of CRDF’s focus has been on HLB.
