Symposium on seed risks
THE one-day symposium sponsored by the Plant Biosecurity Co-operative Research Centre and the Australian Government Department of Agriculture and Water Resources provided an overview of the management of risks posed by pathogens carried by vegetable seed focussing on international regulation, current requirements for seed testing, the effectiveness of diagnostics and alternative systems for assuring clean seed supply.
The aims are to consider the pros and cons of the arrangements for safe seed trade and to facilitate discussion among a small group of regulators, scientists, and seed company and grower representatives.
Currently Australia has a testing regime in place to detect viroids in tomato and capsicum seed and to detect cucumber green mottle mosaic virus (CGMMV) in cucurbit seeds.
National seed associations are promoting alternatives to testing.
The regulation and detection of viroids and CGMMV will be presented at the symposium, as examples of the risks and the processes that are in place to deal with the risks presented by seed-borne pathogens.
A small group of experts in the area will be invited, including representatives of NPPOs of key countries, diagnostic scientists and virologists, representatives of the major seed companies and representatives of the Australian vegetable industry.
