Distribution of some harmful, invasive and quarantine weeds on the territory of Serbia - part I: Spatial distribution and frequency of eight weed species

Abstract

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 retroflexus, A. hybridus, Ambrosia artemisiifolia, Asclepias syriaca, Avena fatua and Calystegia sepium) on the territory of Serbia using a 10x10 km 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).

U radu je prikazana distribucija i zastupljenost nekih ekonomski štetnih, invazivnih i karantinskih korovskih vrsta (Abutilon theophrasti, Agropyrum repens, Amaranthus retroflexus, A. hybridus, Ambrosia artemisiifolia, Asclepias syriaca, Avena fatua i Calystegia sepium), na području Srbije, na UTM mapi, razmera 10x10 km. Snimanjima su obuhvaćene sve kategorije obradivih površina: strna žita, okopavine, višegodišnje krmne biljke, višegodišnji zasadi, strništa i nepoljoprivredne površine. Ocena zastupljenosti kartiranih vrsta rađena je po skali 1-4 (1 - vrsta se sreće pojedinačno i zauzima do 5% površine; 2 - sreće se i zauzima 5-25% površine; 3 - sreće se često i zauzima 25-50% površine; 4 - vrsta preovladava nad gajenom biljkom i zauzima preko 50% površine).
