Yellow Decline is a bacterial disease caused by Candidatus Liberibacter solanacearum (CLso). The bacterium lives in the phloem and is spread by psyllid insects. Different CLso haplotypes infect different crop groups, with Apiaceae-associated haplotypes causing Yellow Decline in carrots, celery, parsley and parsnip.
