 (a) at least one grass herbicide that is suspended or dissolved in a non-aqueous liquid phase    (b) at least one herbicide of the sulfonylurea type that is suspended in a non-aqueous liquid phase, and    (c) at least one non-ionic or anionic, surface-active substance or a mixture of the non-ionic and anionic surface-active substances    
     
     
         2 . Composition according to  claim 1 , containing as the grass herbicide cyhalofop, pyriminobac, cafenstrole, mefenacet, fentrazamid, oxaziclomefon, pentoxazone, etobenzanid, indanofan, epoprodan, pretilachlor or a compound of formula I  
       
         
           
           
               
               
           
         
       
       or a mixture thereof.  
     
     
         3 . Composition according to  claim 1 , containing as the herbicide of the sulfonylurea type pyrazosulturon, bensulfuron, azimsulfuron, imazosulfuron, ethoxysulfuron, cyclosulfamuron, halosulfuron or cinosulfuron or a mixture thereof.  
     
     
         4 . Composition according to  claim 1 , containing as non-aqueous liquid phase a vegetable or mineral oil or a mixture of these oils.  
     
     
         5 . Composition according to  claim 1 , containing as the non-ionic, surface-active substance, an ethoxylated vegetable oil, ethoxylated fat alcohol, ethoxylated alkylphenol, ethoxylated polyethylene glycol or propylene glycol or copolymers thereof, ethoxylated tristyrylphenol derivative, oleyl polyglycol ether or silicone surfactant, or as the anionic surface-active substance, a dodecylbenzene sulfonate, sulfosuccinate, ethoxylated tristyrylphenol sulfate or phosphate, alcohol ether sulfonate, lignin sulfonate, ethoxylated phenol sulfate or polycarboxylate or a mixture of these non-ionic and anionic, surface-active compounds.  
     
     
         6 . Composition according to  claim 1 , containing as the grass herbicide pretilachlor or the compound of formula I or a mixture thereof suspended or dissolved in a vegetable oil, as the herbicide of the sulfonylurea type bensulfuron, pyrazosulfuron, azimsulfuron, imazosulfuron or cinosulfuron or mixtures thereof suspended in a vegetable oil, and as the surface-active substance a mixture of non-ionic and anionic compounds.  
     
     
         7 . Composition according to  claim 6 , containing as the grass herbicide the compound of formula I and as the herbicide of the sulfonylurea type cinosulfuron.  
     
     
         8 . Composition according to  claim 6 , containing as the grass herbicide pretilachlor and as the herbicide of the sulfonylurea type cinosulfuron.  
     
     
         9 . Composition according to  claim 6 , containing as the grass herbicide pretilachlor or the compound of formula I or a mixture thereof, suspended or dissolved in rapeseed oil or rapeseed oil methyl ester or in a mixture thereof, as the herbicide of the sulfonylurea type bensulfuron suspended in rapeseed oil or rapeseed oil methyl ester or in a mixture thereof, and as the surface-active substance a mixture of a non-ionic with an anionic compound selected from castor oil ethoxylate, dodecylbenzene sulfonate, ethoxylated tristyrylphenol sulfate and oleyl polyglycol ether.  
     
     
         10 . Composition according to  claim 9 , containing as the grass herbicide the compound of formula I.  
     
     
         11 . Use of the liquid herbicidal composition according to  claim 1  in the control of undesired plant growth in crops of cultivated plants.  
     
     
         12 . Use according to  claim 11  for the control of undesired plant growth in rice crops by means of direct application of the composition to already flooded paddy fields, to paddy fields that are just being flooded, or during planting of the rice plants.
