Need

The need for approved ag-vet chemicals was demonstrated during the response to the outbreak of the exotic pathogen white spot syndrome virus (WSSV) in 2016. WSSV is one of a number of exotic pathogens that have caused severe economic impacts for prawn aquaculture internationally. Review of the response to WSSV highlighted the need to access a number of ag-vet chemicals for use in disease prevention and control programs that have been developed by Biosecurity Queensland and industry, in conjunction with overseas experts. This application has been prepared to provide funds to commence generating 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 that is needed to control crustacean disease vectors in water and on equipment.

There is limited published data on trichlorfon efficacy to kill Tiger prawns (Penaeus monodon), despite a range of data on efficacy in other species.
The APFA completed Pre-application Assistance (PAA) from the APVMA for the use of trichlorfon to rapidly kill prawns and other crustacea in 2017. APVMA intially indicated that data to meet module 7.3 environmental fate and behaviour assessment and a module 8.1 efficacy assessment is required prior to lodgement of an application for the proposed trichlorfon use.
Subsequently APVMA requested an application to be lodged with a complete public realm data set to consider. This data needs to be sourced and assembled.
APVMA may request further data to be generated in response to the lodgement of the application which is proposed to be gathered under this project for trichlorfon, and potentially some of the other candidate chemicals.

Objectives

1. Compile public domain data ready for submission to APVMA for trichlorfon MUP
2. Compile public domain data ready for submission to APVMA for hydrogen peroxide MUP
3. Compile data for copper sulfate, sodium and calcium hypochlorite and benzylkonium chloride to progress towards application-ready status
4. Collect field data to support trichlorfon use as advised by APVMA

Evaluation of point of care (POC) tests for White Spot Syndrome Virus (WSSV)

1. Determine the analytical and diagnostic performance characteristics (ASe, ASp, DSe, DSp, repeatability and applicability) of three commercially available immunochromatographic WSSV POC test kits for the detection of WSSV in clinically-affected prawns.
