During the period 2023-2024, a field study with common wheat, Avenue variety was conducted. The experiment was set up in a production field in the village of Dobroplodno, Vetrino municipality, Bulgaria. The evaluated herbicidal products were Biathlon® 4 D (714 g/kg tritosulfuron + 54 g/kg florasulam), Ergon® WG (68 g/kg metsulfuron-methyl+ 682 g/kg tifensulfuron-methyl), Acurat Extra® WG (682 g/kg tifensulfuron-methyl + 70 g/kg metsulfuron-methyl), Aminopielic® 600 SL (600 g/l 2,4 amine salt), and Corida® 75 WDG (750 g/l tribenuron-methyl). The herbicidal products were applied as foliar treatments. The weed infestation of the experimental field was presented by Anthemis arvensis L., Lamium amplexicaule L., Consolida regalis S.F. Gray, Papaver rhoeas L., Sinapis arvensis L. and Convolvulus arvensis L. The infestation with these weeds resulted in a very low average grain yield for the untreated control (3.97 t ha-1). The highest biological yield of grain is obtained after using Biathlon 4 D (4.96 t/ha-1) was found.
