A response plan for Citrus Canker (Xanthomonas citri) in the Northern Territory was endorsed on 11 May 2018 by the National Management Group (NMG). The NMG comprises all Australian governments and affected industries made up of Citrus Australia and Nursery Garden Industry Australia
In early April 2018, citrus canker was detected in Darwin, Northern Territory. It was detected on a variety of West Indian lime, grown for the retail trade. It has not been detected in commercial citrus growing areas. Surveillance activities in citrus growing areas in the Greater Darwin Rural Area are ongoing.
The NT Department of Primary Industries and Resources is responding to the detection. They are working with the retailers and production nurseries and other jurisdictions to undertake tracing activities.
Following tracing and testing of nursery plants imported from Darwin, there are confirmed and linked cases of citrus canker on three properties, two at Kununurra and one in Wyndham, in Western Australia's north.
All infected and at risk plant material is being dealt with under strict biosecurity procedures.
Citrus canker has been previously found and successfully eradicated in Australia.
If you think you have a plant with citrus canker, or if you have recently bought citrus plants from a Darwin or Palmerston retail outlet, please contact the Exotic Plant Pest Hotline on 1800 084 881. When phoning the hotline you can arrange to submit a photo for preliminary diagnosis. The photo should be a clear image of the suspect plant, the disease symptoms and the plant's label, if you still have it.
