Argentina free of citrus disease
Argentine authorities have indicated success in controlling and eradicating the major citrus fruit disease, citrus greening ( Candidatus liberibacter). The national animal and plant health inspection service, the Senasa, declared a nationwide “phytosanitary emergency” in December 2009, following detections ( Agrow No 586, p 16). It banned the movement of propagation materials, plants and parts except the fruit itself, across the country, without its authorisation. That led to early success in controlling the spread of the disease. But a recent survey of over 5,000 orchards and citrus-growing areas across several states has yet to uncover a single case, the service says. Tests on 3,000 samples that were suspected of insect vector infestation have proved negative, the Senasa notes.
