TRANSGENIC canola has left farmers’ fields in US cropping State North Dakota, and is growing along roadsides, and near petrol stations and grocery stores at some distance from farms.
Reported by the news arm of science journal Nature, the North Dakotan survey of GM canola gone feral also found that two GM varieties from Monsanto and Bayer, each resistant to a different herbicide, had crossed to produce a plant resistant to both glyphosate and gluphosinate.
Versions of these herbicide-resistant varieties are being grown in Australia.
Roadside sproutings of GM canola are nothing new, even in Australia, and Canada has reported an unintended transgenic GM canola cross in which a single plant carried three different transgenic traits.
However, GM is now fully embedded in North American farming systems.
Australia’s youthful GM sector still has time to ask questions and enact policy about unintended consequences when transgenic crops leave the paddock.
