CROPS in South Australia being contaminated from genetically modified material from over the border is an inevitability, according to international environmental lawyer Duncan Currie, who visited Adelaide last week. This comes as GM farmers in Victoria opened up their farms to allow other growers to see the results of their first season of Roundup Ready canola. Early sowing and no cultivation, good weed management and more flexibility in cropping options were some of the reasons the farmers gave for opting to try GM canola in its first season.
