WA’s non-genetically modified grain sector could vanish within the next 10 years due to contamination from GM crops, some farmers and conservation groups fear. Nic Dunlop, environmental science and policy co-ordinator for the Conservation Council of WA, says feral GM canola plants have been found on road verges in the state’s Esperance district some 20 kilometres away from the nearest GM crop. The discovery shows that the requirement for a five-metre gap between GM and non-GM crops under the state government’s limited commercial-size trials is ineffective.
