THE LNP has moved to force Wilmar Sugar and Queensland Sugar Limited to resolve their differences.
Opposition leader Tim Nicholls announced on Tuesday if the two companies did not agree in the next two days to end the dispute before the end of the month the LNP would move to amend the Sugar Industry Act.
Mr Nicholls said the amendments would compel millers and marketers to go to arbitration.
"If Wilmar Sugar and Queensland Sugar can't agree or don't resolve the dispute by February 28, the LNP will act and amend the Sugar Industry Act," Mr Nicholls said.
"Everyone in the industry is sick to death of this and it needs to end. Both parties need to grow up, bury their egos and sort this out, otherwise growers will lose out.
"Wilmar and QSL need to provide an iron-clad guarantee within 48 hours that negotiations will be finalised for supply and on-supply agreements by February 28.
"If not, then the LNP will introduce amendments to State Parliament compelling millers and marketers to go into arbitration."
The sugar industry dispute has taken on added political weight in recent days after Federal Dawson MP George Christensen threatened to defect to One Nation if the Federal Government did not step in and resolve the dispute.
Mr Nicholls said the LNP was committed to protecting the industry.
"While others are latecomers to the issue of protecting Queensland's $2 billion sugar industry, I have been listening to my colleagues Deb Frecklington, Andrew Cripps, Dale Last and Jason Costigan and growers on my numerous journeys to Central and North Queensland since I became Queensland LNP Leader."
Deputy Opposition Leader Deb Frecklington said the proposed changes would not impact existing agreements but give greater protection to growers in future disputes.
