THE WESTERN Australian government’s plans to conduct trials on genetically modified canola have hit a speed hump, with an upper house motion tabled to design to stall the trials. Late last week, a disallowance motion was put to the WA upper house in a bid to halt the trials, as we head deeper into April and the traditional canola sowing window for much of the state. It was moved by Greens member Paul Llewellyn and was passed with the assistance of independent Anthony Fels.
