Abstract

Single and sequential applications of mefluidide {N-[2,4-dimethyl-5-[[(trifluoromethyl)sulfonyl] amino] phenyl] acetamide} and acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid} were evaluated in the field for velvetleaf (Abutilon theophrasti Medic. ♯ ABUTH) and common cocklebur (Xanthium pensylvanicum Wallr. ♯ XANPE) control in soybeans [Glycine max (L.) Merr. ‘Williams’]. Acifluorfen was applied at 0.4 or 0.6 kg ai/ha alone or 3, 5, or 7 days following application of 0.1 or 0.3 kg ai/ha mefluidide. Acifluorfen applied alone provided acceptable control of velvetleaf and common cocklebur in the two- and three-leaf stage of growth, but acifluorfen was not as effective when applied to weeds with five to eight true leaves. Sequential applications of mefluidide and acifluorfen often increased velvetleaf and common cocklebur control, compared to either herbicide applied alone.
