This contingency plan delivers the information available as of October 2018 on disease epidemiology, virus diagnostic methods, and potential control measures to assist with an appropriate biosecurity response in case of an ADD incursion into Australia. ADD is caused by a mixed infection of lucerne with up to five different viruses that may pose a potential threat to the Australian lucerne seed and hay industry.
This contingency plan includes recommendations for the steps that should be considered when an ADD response plan is required. Any response plan developed from this contingency plan should follow the steps detailed in the Plant Health Australia 2018 PLANTPLAN (www.planthealthaustralia.com.au) and be confirmed by the National Management Group (www.directory.gov.au/portfolios/agriculture-and-water-resources/national-management-group) before implementation.
