Currently there are no approved treatment options to assist control of ponds and water to provide biosecure operation of farms and for responding to outbreaks of white spot disease caused by the exotic pathogen white spot syndrome virus (WSSV). WSSV is one of a number of exotic pathogens that have caused severe economic impacts for prawn aquaculture internationally and review of the response to an incursion in Queensland in 2016 has highlighted the need to access a number of ag-vet chemicals for use in disease prevention and control programs. This investment will generate the data required to support applications to the APVMA, seeking approval for minor-use of the highest priority ag-vet chemicals trichlorfon, sodium/calcium hypochlorite; hydrogen peroxide, copper sulfate and benzylkonium chloride needed to control crustacean disease vectors in water and on equipment.
