STRONG prices for canola have meant farmers have flocked to the crop, with this year’s seeding forecast to be up by 245,000 hectares on the 2010-11 season. Prices are hovering at about $580 a tonne port, with a slight premium in South Australia [...] ”The Europeans don’t buy GM canola, so South Australia’s status as GM-free is leading to a small premium to east coast non-GM prices,” [Emerald Group’s general manager of trading Chris Kochanski] said.
