       4 . The herbicidally active composition as claimed in  claim 1 , in which the weight ratio herbicidal:safener is from 1:100 to 100:1. 
   
   
       5 . The herbicidally active composition as claimed in  claim 1 , additionally comprising
 (C) one or more solvents, preferably organic solvents,   (D) one or more sulfosuccinates,   (E) one or more agrochemically active compounds different from (A) and (B), and/or   (F) customary auxiliaries and additives.   
   
   
       6 . The herbicidally active composition as claimed in  claim 1  in form of a liquid formulation. 
   
   
       7 . A liquid formulation, comprising
 (A) one or more sulfonylureas from the group consisting of metsulfuron, thifensulfuron, tribenuron, chlorsulfuron and their salts and esters,   (B) one or more safeners from the group consisting of cloquintocet and its salts and esters,   (C) one or more solvents, preferably organic solvents,   (D) optionally one or more sulfosuccinates,   (E) optionally one or more agrochemically active compounds different from (A) and (B), and   (F) optionally customary auxiliaries and additives.   
   
   
       8 . The liquid formulation as claimed in  claim 7 , wherein said one or more sulfonylureas (A) are present in a herbicidally effective amount and said one or more safeners (B) are present in an antidote-effective amount. 
   
   
       9 . The liquid formulation as claimed in  claim 8  in the form of an oil suspension, oil suspension concentrate, suspoemulsion, suspoemulsion concentrates, emulsion, emulsion concentrate, micoemulsion, microemulsion concentrate, emulsifiable concentrate or spray liquors obtainable therefrom. 
   
   
       10 . A method for controlling harmful plants in plant crops, which comprises applying the components of the herbicidally active composition as claimed in  claim 1  jointly or separately to the harmful plants, crop plants, plant seeds or to the area in which the plants grow. 
   
   
       11 . The method as claimed in  claim 10 , wherein the crop plants are from the group consisting of corn, wheat, rye, barley, oats, rice, sorghum, cotton and soybeans. 
   
   
       12 . The method as claimed in  claim 10 , wherein the crop plants are transgenic or tolerant owing to selective breeding. 
   
   
       13 . (canceled) 
   
   
       14 . A process for preparing a herbicidally active composition as claimed in  claim 1 , which process comprises mixing the components. 
   
   
       15 . A sulfonylurea/safener combination, comprising
 (A) one or more sulfonylureas from the group consisting of metsulfuron, thifensulfuron, tribenuron, chlorsulfuron and their salts and esters, and   (B) one or more safeners from the group consisting of cloquintocet and its salts and esters.   
   
   
       16 . The sulfonylurea/safener combination as claimed in  claim 15 , in which the sulfonylureas (A) are selected from the group consisting of metsulfuron-methyl, thifensulfuron-methyl, tribenuron-methyl, chlorsulfuron and their alkali metal salts. 
   
   
       17 . The sulfonylurea/safener combination as claimed in  claim 15 , in which the safener (B) is cloquintocet-mexyl. 
   
   
       18 . The sulfonylurea/safener combination as claimed in  claim 15 , additionally comprising one or more agrochemically active compounds (E) different from (A) and (B). 
   
   
       19 . A method for controlling harmful plants in plant crops, which comprises applying the components of the liquid formulation as claimed in  claim 7  jointly or separately to the harmful plants, crop plants, plant seeds or to the area in which the plants grow. 
   
   
       20 . A process for preparing a liquid formulation as claimed in  claim 7 , which process comprises mixing the components.
