A property at Thorpdale, in West Gippsland, has been found to have potato cyst nematode (PCN) and a freeze has been put on potato trade from the area.
John Hodgkin from the Thorpdale branch of the Victorian Farmers Federation says the Government has to step in and manage the issue.
"It is quite possible PCN is in all the states of Australia, it's just they haven't been looking for it, so they haven't been testing for it there whereas because of our seed industry and our responsibility nature of our seed industry we have been testing for it here and that's how we've found it," he said.
