Abstract: At the Experimental Base of the Institute of Viticulture and Enology, Pleven, Bulgaria it was carried out a three-year planting (2014, 2015 and 2016) of a vineyard for chemicals testing for weed control. Each variant included 20 Cabernet Sauvignon vines grafted to Berlandieri X Riparia Selection Oppenheim 4 (SO 4) rootstock as it was repeated every year of the study. A single spray with Wing P (pendimethalin 250 g/l + dimethenamid P 212.5 g/l) at doses of 0.4 and 0.6 l/da was performed immediately after planting the vines and once with Stratos Ultra (100 g/l cycloxydim) at a dose of 0.2 l/da during the active vegetation stage of the wheat weeds. It was not found a negative impact on the bud germination and the shoot growth and maturation. Applied at a dose of 0.6 l/da, Wing P showed the best control over one-year weed vegetation in the vineyard as the treated vines had more intensive development and mature growth of greater length and mass.
