South Australian Farmers Federation president Peter White said yesterday the only issue with GM technology in SA was the timing of its introduction. ”Worldwide, it is the fastest-growing new technology in the history of agriculture,” Mr White said. ”If we are going to feed nine billion people we don’t have much choice and the decision will be driven by economics and agronomic advantages.” His comments come as the GM-Free Australia Alliance meets in Adelaide with a panel of GM-free supporters and Senator Nick Xenophon holding a public forum tonight to push their case to maintain SA’s GM-free status.
