Summary

Citrus canker was detected on three commercial citrus orchards in the Emerald district of Queensland between June 2004 and May 2005. In accordance with the nationally agreed Response Plan, all high-risk host plants within the PQA, including approximately 495,000 commercial citrus trees and 4,000 residential trees, were destroyed prior to 31 December 2005 in preparation for an 18-month ^^host-free^^ period. Low risk native citrus (Citrus glauca) were also destroyed within buffer zones around all previous commercial orchards and the Emerald township. Remnant native citrus located outside these destruction zones were surveyed at 90-day intervals for a period of 18 months and demonstrated an absence of the disease in those areas. Replanting of commercial citrus orchards in the PQA commenced on 1 July 2007. All planting material was inspected prior to entry into the PQA. Surveillance is presently being undertaken at 90-day intervals on all re-planted citrus to confirm there is no evidence of reinfestation and the disease has been eradicated. Extensive surveillance of all other areas of Australia outside the PQA confirmed the absence of the disease in those areas. There has been no detection of citrus canker in the PQA since May 2005.

Danger
Citrus canker is currently the subject of a national eradication program in the Pest Quarantine Area (PQA) around the township of Emerald in Queensland. Ongoing surveillance is being undertaken on re-planted citrus orchards in the PQA and will continue until 31 December 2008 to verify pest freedom. Eradication is expected to be declared in early 2009 should surveys demonstrate a continued absence of the disease.
