During the period of 2018/2019-2019/2020, a field plot trial with the winter wheat variety Avenue was carried out. The experiment aimed to determine the efficacy of herbicide products for broadleaf weeds control. The studied products were Biathlon 4 D (tritosulfuron + florasulam) + Dash (adjuvant), Mustang (2.4 D ester + florasulam), and Sekator OD (iodosulfuron + amidisulfuron). The obtained results were compared with the untreated control. The efficacy of the herbicides against the weeds corn chamomile (Anthemis arvensis L.), common poppy (Papaver rhoeas L.), cleavers (Galium aparine L.), wild mustard (Sinapis arvensis L.), and forking larkspur (Consolida regalis Gray) was evaluated. High herbicide efficacy against all existing weeds was recorded. All evaluated parameters for the treated variants as plant height at the end of the vegetation, absolute and hectoliter seed mass, as well as winter wheat grain yields, had higher values compared to the untreated control.
