HLB Control: A New Potential Method

Dan Citrus, Huanglongbing (HLB)/Citrus Greening, Research

A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher has found a material that can be used to silence essential genes within Asian citrus psyllids and in the HLB-causing bacterial pathogen that the psyllids spread. The material is  2’-deoxy-2’-flouro-d-arabinonucleic acid antisense oligonucleotides (FANA ASO), small-sized single-stranded nucleic acids.  The discovery was made by Kirsten Pelz-Stelinski, an associate …

The Search for Canker-Resistant Satsumas

Dan Citrus, Huanglongbing (HLB)/Citrus Greening, Research

Citrus canker, a highly contagious bacterial disease of citrus, was first detected in Louisiana around 1914 and declared eradicated by 1940. However, the disease reappeared in the state in 2013. Right now, there are no effective treatments to eliminate the disease after the infection has occurred. Adding insult to injury, Louisiana’s hot and humid climate is especially conducive to the …
