THE Sugar Cane Growers Council is concerned about the indiscriminate burning of cane in the Penang mill area.
Acting CEO Sundresh Chetty said arson was suspected in most cases.
He warned farmers that such action was detrimental to all stakeholders.
"We are very concerned about the indiscriminate burning of cane, particularly in the Penang mill area," Mr Chetty said.
"Most of the cases have been reported to the police, which are suspected to be arson.
"Police and military patrols have been arranged in the sectors and anyone caught will be dealt with seriously and will have to face the full brunt of the law."
Mr Chetty said the indiscriminate burning of sugar cane reduced the quality of cane and reduced potential earnings to the industry.
"Nobody wins and growers stand to lose when cane is burnt.
"We are aware that some cane burning can be attributed to arsonists and we are also aware that some cane is burnt by growers and we are urging that this activity be stopped immediately," he said.
Apart from reducing cane quality and revenue, sugar cane burning also contributes to soil and environmental damage, poor sugar cane recovery, more costly and less efficient processing and reduction in bagasse energy potential.
