Citrus canker on an orange
The Department of Agriculture and Fisheries (DAF) has issued a Movement Control Order (MCO) (PDF, 455.4KB) Notice for citrus canker and carriers. The MCO commences on 24 April 2018 and will stay in effect for three months unless revoked earlier.
Citrus canker (Xanthomonas citri pv. citri) also known as Xanthomonas citri subsp. citri, was detected in the Northern Territory in April 2018.
Citrus canker is a contagious bacterial disease which can affect all citrus plants. The disease can be spread rapidly over short distances by wind-blown rain, weather events and human movement, particularly in tropical and subtropical climates. Infected plants display lesions which form on leaves, fruits and stems, resulting in low plant vigour and a reduction in fruit quality and quantity.
Citrus canker can also be spread on planting media and machinery and equipment used in the production of crops in the citrus family.
Movement restrictions will apply to plants and plant material (including fruit) within the citrus family (Rutaceae) and associated planting media and soil, machinery or equipment coming into Queensland unless they meet certain conditions outlined in the MCO.
New South Wales, Victoria and Western Australia have also implemented movement restrictions for citrus canker and carriers. Other Australian states are also expected to implement movement restrictions for citrus canker and carriers in the near future.
If you suspect citrus canker on your property, report it immediately to the Exotic Pest Plant Hotline on 1800 084 881 or Biosecurity Queensland on 13 25 23.
