Researchers Study Relative of HLB Pathogen
Sometimes the most niche plant pathogen packs the greatest punch. Such is the case for the Florida citrus industry, which has seen a 70% decline in its orange production since the introduction of HLB in 2005. HLB is also known as citrus greening disease. The bacteria Candidatus Liberibacter asiaticus cause this disease, which spreads via a flying insect. When the …
