Abstract

Herbicide combinations comprising an effective amount of components (A) and (B) have improved herbicidal action wherein (A) is one or more herbicides of the formula (I) or salts thereof in which R 1 is (C 1 -C 8 )-alkyl, (C 3 -C 4 )-alkenyl, (C 3 -C 4 )-alkynyl, or (C 1 -C 4 )-alkyl which is mono- to tetrasubstituted by radicals selected from the group consisting of halogen and/or (C 1 -C 2 )-alkoxy, R 2 is I or CH 2 NHSO 2 CH 3 , R 3 is methyl or methoxy and Z is N or CH and (B) denotes one or more herbicides which act selectively in some monocotyledonous crops against monocotyledonous and/or dicotyledonous harmful plants, which herbicides are selected from the group of compounds consisting of flucarbazone, BAY MKH 6561 (procarbazone), florasulam, halosulfuron, tritosulfuron, picolinafen, cinidon-ethyl, mesotrione, metosulam, clopyralid, flufenacet, flumetsulam, flupoxam, prosulfocarb, flurtamone, aclonifen, hexazinone, asulam, diuron, ametryn, isoxaflutole, amicarbazone and trifloxysulfuron.

       13 . The herbicide combination as claimed in claim  1  which additionally comprises one or more safeners. 
   
   
       14 . A method for controlling harmful plants which comprises applying a herbicide combination as defined in claim  1  onto the plants, parts of plants, plant seeds or the area where the plant grows. 
   
   
       15 . The method as claimed in  claim 14  for the selective control of harmful plants in plant crops. 
   
   
       16 . The method as claimed in  claim 15  for the control of harmful plants in crops of monocotyledonous plants.
