On this purpose 109 samples were collected from wheat producers, demonstration products of provincial directorate of agriculture and local flour factories. This samples were separated from live and dead materials by sieving with different mesh sized sieves and weeds seeds were collected from residual matter. The species of weed seeds were identified by examination under a binocular microscope. The mean rate of seed mixture of weeds into wheat grains in Tokat province was determined as 0.57%. After the exanimation of these mixed seeds 49 weed species belonging to 16 families were identified. The highest mixture rate was evaluated in Poaceae family members with 12 different species. Seven different species belonging to Brasicaceae families were also identified. The highest mixture rate (0.73%) were observed flour factory samples while rate in demonstration and wheat producer samples were 54% and %44 respectively. Total of 54 400 g wheat was examined, the amount of foreign matter (weed seed+dead matter) was measured as 601.6 g, and mixture rate was estimated as 1.1%}, number={2}, publisher={Türkiye Herboloji Derneği}
