Optimize Zinc and Potassium Applications to Prevent Fruit Drop
By Fernando Alferez, Daniel Boakye, Murillo De Sousa and Pablo Orozco After HLB was first detected in Florida, increase in disease-associated preharvest fruit drop in affected trees has significantly reduced grower returns. Fruit drop is normal in healthy citrus, accounting for 10% to 15% of the total crop. However, under endemic HLB conditions and depending on the variety, crop loss …
Breeder Advice on Nutrition, Scions and Rootstocks
Citrus breeder Jude Grosser recently shared tips on tree nutrition and discussed some scion/rootstock combinations that should work well for trees producing juice oranges. NUTRITIONGrosser became very interested in citrus nutrition several years ago in an effort to keep his newly bred trees healthy in the face of HLB. The University of Florida Institute of Food and Agricultural Sciences professor …
A Grove-First Approach
In the nearly two decades that huanglongbing (HLB) has plagued Florida citrus groves, about $1 billion has been spent in the search for solutions. A lot of great scientists in Florida and around the world have worked on the problem, and a silver bullet, if there is one to be found, has been elusive. Researchers, along with growers, have developed …
Diseases Without Borders: Leprosis and Yellow Vein Clearing Viruses
By Ozgur Batuman Plant virus diseases are unusually difficult to manage if introduced into new production sites. Citrus-infecting viruses, particularly those spread by insect vectors, are no exception to this. Florida is regularly challenged by a barrage of invasive pests and pathogen species that could devastate the citrus industry. Viruses causing citrus leprosis and citrus yellow vein clearing diseases are …
Growers May Comment on Farm Bill at Listening Session
UPDATE: Both the Oct. 9 and Oct. 13 listening sessions have been postponed. Florida Commissioner of Agriculture Wilton Simpson will host a farm bill listening session with U.S. Rep. Kat Cammack in attendance on Oct. 13. The session will allow Florida’s growers and ranchers to voice recommendations for the 2023 U.S. farm bill and related agricultural issues. The farm bill …
Combine Plant Growth Regulators for Most Benefit
Using the plant growth regulators (PGRs) gibberellic acid (GA), 2,4-D and cytokinin in combination can maximize the benefit for HLB-affected trees, researcher Tripti Vashisth reported recently. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of citrus horticulture and production works at the Citrus Research and Education Center in Lake Alfred. She discussed the benefits of …
FFVA: Work Needed on Miami-Dade Heat Bill

Treat HLB Trees With the Right PGR at the Right Time
By Tripti Vashisth, Wesley Webb and Taylor Livingston As trees become symptomatic for HLB, leaves experience an imbalance of plant hormones. This hormonal imbalance exacerbates HLB symptoms and can lead to more stem dieback, poor vegetative growth and fruit drop. This ultimately leads to reduced bearing wood, resulting in yield losses and tree decline. Thus, the use of growth-promoting hormones …
