In Punjab, a fine of Rs 43 lakh was imposed on farmers for defying the ban on stubble burning and fine of Rs 52 lakh was levied on 26 combine harvester operators for not installing super straw management system (SMS).

Every year, Punjab and Haryana are blamed for the rising air pollution and smog due to stubble burning by farmers. Punjab alone generates 20 million tonne of paddy stubble annually.
