The October issue of Specialty Crop Grower magazine features citrus research updates, industry developments and more. Coverage ranges from a grapefruit disorder to citrus breeding efforts to rebuilding Florida’s production.
The Citrus Industry section, begins on page 22 with “Unraveling the greasy-green mystery in Florida grapefruit,” by Megan M. Dewdney, Eva L. Mulandesa and Mark A. Ritenour. University of Florida Institute of Food and Agricultural Sciences researchers investigated a stubborn green discoloration that has caused significant losses for Florida grapefruit growers and packers. The research examines the relationship between greasy-green symptoms and the fungus responsible for greasy spot and rind blotch, while also exploring postharvest treatments. Findings indicate that conventional degreening practices cannot adequately correct the disorder.
The October Buzzz column covers the registration of the CarriCea T1 citrus rootstock, which has attracted substantial grower interest, as well as research into beneficial soil bacteria that could improve citrus nutrient uptake and fertilizer efficiency. The Buzzz also includes information from a report on the global orange juice supply and demand outlook.
A Pest Alert article highlights the invasive ghost snail, which can clog microjet sprinklers and damage citrus.
In his October Citrus Nursery Source column, Peter Chaires examines the challenges of getting new citrus varieties from development into commercial groves. Limited field-trial data makes it difficult for growers and nurseries to evaluate new varieties across different locations and rootstock combinations. The column discusses efforts to expand standardized trials and provide growers with better information for replanting decisions.
The 2026 Citrus Achievement Award feature spotlights recipient Ned Hancock and his perspective on industry recovery. Hancock discusses encouraging production and fruit-quality improvements, the potential contributions of oxytetracycline trunk injection and the importance of continued research.
Finally, in Pieces of the Past, Brenda Eubanks Burnette traces the life and influence of John Stansel Taylor, a citrus grower, packinghouse operator and civic leader who helped establish Pinellas County.
