Delaying <i>Candidatus</i> Liberibacter asiaticus infection of citrus trees through use of individual protective covers and systemic delivery of oxytetracycline.

ABSTRACT: Huanglongbing (HLB), or citrus greening, remains one of the most destructive diseases affecting citrus production globally. Associated with the phloem-limited bacterium Candidatus Liberibacter asiaticus (CLas) and vectored by Diaphorina citri, HLB leads to canopy decline, fibrous root loss, and reductions in fruit yield and quality. Recently, the systemic delivery of oxytetracycline (OTC) via trunk injection was approved in Florida as a targeted therapy to reduce CLas titers and improve tree health. In parallel, Individual Protective Covers (IPCs) have been adopted to delay CLas infection in newly planted citrus trees by vector exclusion. This study investigates the combined use of IPCs and trunk injection of OTC for post-IPC therapy. 'Valencia' sweet ora
