The disclosure relates to a herbicide combination which comprises D-Napropamide (D-(-)-N,N-diethyl-2-(&alpha；-naphthoxy)propionamide)； and a second herbicide which is more active against monocotyledonous weeds than dicotyledonous weeds, wherein the second herbicide is selected from (i) S-Metolachlor； (ii) Metolachlor； (iii)Clomazone； (iv) Flufenacet； (v) Diflufenican； (vi) Flufenacet + Diflufenican； (vii) Benfluraline； (viii) Quinmerac； (ix) Metazachlor； (x) Quinmerac + Metazachlor； (xi) Glufosinate； (xii) Metribuzin； (xiii) Clomazone + S-Metolachlor； (xiv) Dimethachlor； (xv) Benazolin； (xvi) Carbetamide； (xvii) Clethodim； (xviii) Cycloxydim； (xix) Sethoxydim； (xx) Clopyralid； (xxi) Cyanazine； (xxii) Simazine； (xxiii) Diclofop； (xxiv) Fenoxaprop-P； (xxv) Fluazifop-P； (xxvi) Haloxyfop-P； (xxvii) Propaquizafop； (xxviii) Quizalafop； (xxix) Dimefuron； (xxx) Flumetsulam； (xxxi) Propyzamide； (xxxii) Pyridate； (xxxiii)Trifluralin； (xxxiv) Pethoxamid； (xxxv) Pendimethalin； (xxxvi) Clomazone + Dimethachlor and (xxxvii) Clomazone + Metazachlor. Also disclosed is the use of D-Napropamide for the selective control of a dicotyledonous weed at a locus, wherein the D-Napropamide is applied in an amount such that it is effective in controlling said dicotyledonous weed yet less active against monocotyledonous plant species at the locus.
