Floristically rich and diverse weed community of sugar beet in our country represented by 150 weed species. They are not all equaly significant in weediness of this crop. Only limited number of them participate in weed community composition. These are: Abuthilon theophrasti, Ambrosia artemisiifolia, Amaranthus retroflexus, Chenopodium album, Cirsium arvense, Convolvulus arvensis, Cynodon dactylon, Digitaria sanguinalis, Hibiscus trionum, Rubus caesius, Echinochloa crus-galli, Polygonum aviculare, Polygonum lapathifolium, Polygonum persicaria, Setaria glauca, Setaria viridis, Solanum nigrum, and Sorghum halepense. In shooting period up to 4-8 weeks upon emergence, sugar beet is under the haviest harmful influence of weeds, especially invasive ones such as: Abuthilon thelophrasti, Ambrosia artemisiifolia, Cirsium arvense, Iva xanthifolia, Sorghum halepense and Xanthium strumarium. Sugar beet growing requires intensive cultural practices, i.e. basic and additional tillage and cultivation. Due to the widening of weed problems, frequent herbicide use in several applications is needed in the longer time period.
