The paper reviews the distribution and frequency of several species from a group of economically harmful, invasive and quarantine weeds (Abutilon theophrasti, Agropyrum repens, Amaranthus retrophlexus, A. hybridus, Ambrosia artemisiifolia, Asclepias syriaca, Avena fatua, and Calystegia sepium) on the territory of Serbia using a 10x10 UTM map. The assessment included all categories of land, fields under small grains, row crops, perennial forage crops, long-term plantations, fallow land and non-agricultural land. The presence of quarantine weeds was rated on the scale from 1 to 4 (1: the species occurs individually, taking less than 5% of the area; 2: 5 to 25% of the area; 3: the species is frequent and takes 25 to 50%; 4: more numerous than the crop and takes more than 50% of the area).
