Field brome (Briomus arvensis) is one of the dangerous and widely spread grassy weeds in the wheat fields in Bulgaria. The species is spread everywhere and sometimes at quite high density. The experiments were carried out during the period 2008 – 2010 in the area of Dryanovo village, Yambol region, in the fields with high density infestation by field brome (Bromus arvensis).
Five leaf systemic commercial chemicals were tested, containing the following active substances: (Axial 050 EC 50 g/L – pinoxaden; Topic 080 EC + antidote – ciodinafop; Puma super 100 EC — 69 g/L – fenoxaprop-P-ethyl; Palas 75 WG 750 g/kg pyroxulam and Hussar max WG mesosulfuron – methyl 30 g/kg + iodosulfuron-methyl 30 g/kg), some of them belonging totally to the spectrum of grassy weed controlling chemicals and others being of a mixed spectrum of effect. The results of the experiments showed from total lack of efficiency of some of those products against field brome, through a partial effect of others, to a 100 percent eradication of that grassy weed species by Palas 75 WG.
