The study of the impact of different methods of weed control in vineyard was carried out in 2015 in the Podgorica sub region. Six different variants of weed control were tested: control, mechanical control, glyphosate (one treatment), glyphosate (two treatments), flazasulfuron and flazasulfuron+glyphosate. A total of 13 weed species from nine families were identified. The Asteraceae family was the most widespread with four species (31%), followed by Poaceae with two (15%), while all other families participated with one weed species each (8%). The dominant weed species in the experimental vineyard were Ambrosia artemisiifolia, Amaranthus retroflexus, Chenopodium album, Sorghum halepense, Heliotropium europaeum and Xanthium strumarium. Annual thermophilic, heliophilic weeds dominated the weed synusia of the vineyard (77%), while perennial species participated with 23%. All applied methods of weed control showed a satisfactory level of efficiency, reducing the number of weed plants and the weed mass per unit area. The best effect in weed control between rows of the vineyard was demonstrated by the variants glyphosate, applied twice (92.7%), flazasulfuron, applied once (92.0%) and glyphosate+flazasulfuron (91.7%). The combination of glyphosate+flazasulfuron (100%) showed the highest efficiency in controlling weeds between the vines in a row. [ABSTRACT FROM AUTHOR] |
