By Tripti Vashisth Recent research has shown benefits of gibberellic acid (GA) application (monthly from September to January) in improving yield and canopy density of HLB-affected trees. These findings have caught the attention of Florida citrus growers. Many have indicated that they are applying GA in their groves as per the University of Florida Institute of Food and Agricultural Sciences …
Early results from a large-scale citrus trial looking for solutions to HLB, also called citrus greening, show tree size does not seem to affect citrus susceptibility to the disease.

By Megan Dewdney Editor’s note: This article originally stated that citrus black spot was in Hardee County. It should have said Hendry County, and has now been corrected. Citrus growers in Florida continue to battle new pests and diseases. They have been learning to manage citrus black spot for the last 12 years. The disease is still localized mainly in …
University scientists, engineers, producers, government agencies and industry officials across the Southeast recently met to brainstorm ways to use artificial intelligence (AI) to help growers. They concluded that they could empower growers and equip farms to increase their economic and environmental sustainability and develop resilient solutions to address climate change by using AI. The three-day conference, Envisioning 2050 in the …

By Fernando Alferez, Ute Albrecht, Susmita Gaire, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers established a field trial in February 2018 to evaluate the efficacy of individual protective covers (IPCs) to prevent Asian citrus psyllids from spreading HLB and to study the effects on tree growth and physiology. The …
Nabil Killiny, an associate professor of plant pathology for the University of Florida Institute of Food and Agricultural Sciences, has been studying the relationship between the bacterium that causes HLB (Candidatus Liberibacter asiaticus) and its vector the Asian citrus psyllid (ACP).
