Further investigation on citrus phantom disorders of unconfirmed viral etiology
Abstract
This brief report expands upon the original review article published in Journal of Citrus Pathology in 2023 on citrus “phantom” disorders of presumed virus and virus-like etiology and addresses five additional disorders: citrus seed-borne virus disorder in New Zealand, bergamot vein yellowing in Greece, bergamot gummosis in Italy, bud knot in Italy, and a disorder resembling citrus crinkly leaf in Cuba. Each disorder is characterized by distinct symptoms and transmission patterns yet remains unresolved in terms of causative agents or conditions. By providing comprehensive information on these phantom citrus disorders, this report aims to serve as an additional reference for the citrus research community, industry stakeholders, and regulatory offices.
