Quarantine in relation to Australian citrus imports and exports

Quarantine in relation to Australian citrus imports and exports The risks of introducing exotic citrus diseases through the importation of citrus fruit, seed and budwood are discussed. The experience with citrus bacterial spot in Florida has demonstrated that species identification and even pathogenicity testing are no longer adequate; serological and biochemical typing are essential before substantial eradication programs are commenced. A protocol for citrus budwood importations is discussed and an example given of the problems caused by accepting virus-free budwood from an ‘approved’ source. Allowing entry of viruses endemic to Australia could have disastrous consequences if more severe strains with a wider host range are introduced. The orange and mandarin stem pitting strains of citrus tristeza virus are examples given. Citrus relatives e.g. ornamentals such as Murraya can be hosts of canker, greening and citrus tristeza virus, and should undergo similar quarantine procedures to those for Citrus spp. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Australasian Plant Pathology Springer Journals

Abstract

The risks of introducing exotic citrus diseases through the importation of citrus fruit, seed and budwood are discussed. The experience with citrus bacterial spot in Florida has demonstrated that species identification and even pathogenicity testing are no longer adequate; serological and biochemical typing are essential before substantial eradication programs are commenced. A protocol for citrus budwood importations is discussed and an example given of the problems caused by accepting virus-free budwood from an ‘approved’ source. Allowing entry of viruses endemic to Australia could have disastrous consequences if more severe strains with a wider host range are introduced. The orange and mandarin stem pitting strains of citrus tristeza virus are examples given. Citrus relatives e.g. ornamentals such as Murraya can be hosts of canker, greening and citrus tristeza virus, and should undergo similar quarantine procedures to those for Citrus spp.
