Grain traders and the WA government are refusing to divulge how much of the genetically modified canola grown in WA last year has been sold, amid reports that sales have been sluggish. While AWB claims the lack of market interest is due to low oil content and the poor finish to the growing season - and not the GM factor - non-GM canola varieties are fetching up to $50 per tonne more than GM canola. While Hansard reveals that WA Minister for Agriculture Terry Redman told parliament that grain traders advised the Department of Agriculture and Food that a significant proportion of the 49,000 tonnes of GM canola grown last year had sold, exactly how much remains unsold, sitting in silos, has proved difficult to uncover.
