Özet: During the period 2014–2016 at the Institute of Viticulture and Enology a trial was carried out to study the impact of the herbicides Gardoprim plus Gold (312.5 g/l s-metolachlor + 187.5 g/l terbuthylazine), Lumax 538 SC (375 g/l s-metolachlor + 125 g/l terbuthylazine + 337.5 g/l mesotrione) and Wing P (pendimethalin 250 g/l + dimethenamid P 212.5 g/l) on the yield of high-quality cuttings for production of vine propagation material. The treatments in the mother vineyard of Cabernet Sauvignon variety (clone D-1) were performed in the spring before the buds germination. The obtained cuttings were grafted in 2015, 2016 and 2017 on Berlandieri X Riparia SO4 rootstock. After the stratification, the grafted cuttings were planted in the nursery and their vegetative manifestations were monitored. The cuttings from the herbicide-treated variants showed viability similar to the control, and their buds germinated with the same intensity. The yield of rooted vines did not differ significantly from the cuttings grown without herbicides, as the highest rate of standard propagation material was obtained with Gardoprim plus Gold (55.45%). The vine biometric indicators exceeded those of the control variant. The application of the herbicides Gardoprim plus Gold, Lumax 538 SC and Wing P for keeping the soil surface free from weeds did not
