Voting on new regulations to the South Australian Genetically Modified Crop Moratorium is expected in State Parliament today.
The changes, which came from recommendations of the GM Select Committee, were introduced by the State Liberal Government and would take effect from December 1.
The Greens were opposed to the way the changes to the regulations were made, and recently reintroduced a Bill so an early parliamentary decision would be made today, November 27, before the December 1 deadline.
According to Grain Producers SA chief executive Caroline Rhodes, SA Best and Labor, which have since joined the call for the disallowance motion, were putting politics before the future of the state's grain industry.
"It is now clear that politics has triumphed over policy within the Labor Party, with no clear way forward for the state's agricultural sector," Ms Rhodes said.
"Instead of disclosing its position on GM crops in August, Labor has dealt a cruel blow to growers in the middle of harvest.
"Hiding behind a strawman argument about regulatory process doesn't change the fact that the State Government is precisely following the intent of the Act, as introduced by the former Rann Government in 2004.
"Growers expect outcomes from Parliament, not disagreements over process.
"What appears to have been lost in this debate is the ongoing economic cost to the industry."
The GPSA has vowed to continue its pursuit of the GM reform on behalf of its members.
