In order to compare the mechanical and chemical control methods of weed potato fields, an experiment was conducted in a randomized complete block design with four replications in summer of 2016 at University of Kurdistan Research Station, located in Dehgolan. Experimental treatments included paraquat herbicide, cultivator, flame weeding. full-season interference and full-season hand weeding were included as control. Results showed that flame weeding compared to paraquat and cultivator caused the highest reduction in density and dry weight of weeds. So that this treatment reduced 88.89 and 82.26 percent density and dry weight of weeds compared to full season interference. Flame weeding produced 3669.17 gr.m-2 potato tuber and increased 37.93 percent tuber yield compared to full season interference. According to the results flame weeding can be recommended as a non-chemical and ecological solution for weed control in Dehgolan region and areas with similar conditions.
