UF/IFAS Citrus Research

Keeping Florida Citrus Growers Informed

This publication contains brief summaries of current research being led by UF/IFAS citrus scientists located at UF/IFAS research centers in Gainesville, the Citrus Research and Education Center in Lake Alfred, Southwest Florida Research and Education Center in Immokalee and the Indian River Research and Education Center in Fort Pierce. This research advances our knowledge about growing citrus in Florida including fighting HLB, improved grove management, and better nutrition recommendations. While definitive recommendations and findings are still in development, these updates provide insights into our ongoing progress. Please contact the faculty listed with each summary for more information or to discuss their research. More resources are available on-line at citrusresearch.ifas.ufl.edu.
