This study represents results lasting three year (2004-2006) investigations of weed flora in the region of Belgrade (Stara Palilula) and Belgrade’s pale (Pančevo rit, Grocka wine county). A total of 175 taxons of vascular plants classified into 136 genera and 39 families were found at various types of ruderal and agricultural habitats. In the ruderal habitats 137 species of weed have been ascertained. In the crops and implantations 104 species of weed have been ascertained. In the wheat crop are consolidated 58, corn 37, sugar beet 40, soybean 46, potatoes 29, fruit-gardens 35, vineyards 44, peas 38, onion, garlic and leek 31, cabbage 27 and pepper 56 weed species. By an analysis of the present life forms of the plants belonging to the investigated weed flora, its hemicryptophytic – therophytic character has been established (49.14%:36.57%). By analyzing ecological indices for 5 main ecological factors, it is determineda domination of plants that prefer submesophyte and subxerophyte habitats, mostly those of neutral to slightly basic reaction, with medium and high availability of minerals, predominantly semi-open to open in character, and mesothermic to thermophilic regarding temperature regime. Phytogeografic analysis of the weed flora revealed the presence of 175 different floristic elements grouped into 8 main area types. The most numerous was the group which belongs to Eurasian areal type (32.57%).
