Abstract:
A study was conducted during 2005 and 2006 to investigate the weeds with major economic impact on agriculture in the Republic of Macedonia. For this purpose six different locations were targeted as a most important Macedonian agriculture centres. Studies revealed that 118 species were identified as problematic weeds in cereals, row crops, fodder crops, vegetables, orchards and vineyards. All weed species belong to 30 families 92 weeds are annuals, 2 weeds are biennial and 24 weeds are perennials. Most of the weeds belong to family Poaceae and Asteraceae. A majority of the weeds (107 species) are terrestrial plants, and a few (5 species) are aquatic weeds. Six of the species are parasitic weeds. Avena fatua Alopecurus myosuroides and Bromus spp. were found the most problematic weeds in small grain production. The harmful effects of Chenopodium album, Amaranthus retroflexus, Echinochloa crus-galli, Sorghum halepense, Agropyron repen, Cynodon dacyilon and Cirsium arvense were noticed on row crops, fodder crops, vegetable, orchards and vineyards. Tobacco, sunflower, tomato, alfalfa and clover are favoured hosts for obligate parasite weeds Orobanche spp. and Cuscuta spp.
