• In citrus, the Huanglongbing Diagnostic Laboratory is in its fourth year of service to citrus growers providing detection of the bacterium, Candidatus Liberibacter asiaticus, by using real-time PCR diagnostics.

• Field trials evaluating biological control agents, systemic acquired resistance (SAR) inducers, antibiotics and many other products on citrus canker caused by the bacterial pathogen, Xanthomonas citri subsp. citri, were just completed for the fourth season.

• We’re cooperatively working on several aspects of citrus black spot, an exotic fungus (Guinardia citricarpa), causing black spots and fruit drop on citrus. It was first found in the Immokalee region in 2010.

Dr. Pamela Roberts is a plant pathologist based at the Southwest Florida Research and Education Center in Immokalee. She can be reached at pdr@ufl.edu.
