Selective herbicides based on a substituted phenylsulfonylaminocarbonyl-triazolinone

Abstract

The present invention relates to selective-herbicidal compositions, characterized in that they contain an effective amount of the compound 2-(2-trifluoromethoxy-phenylsulphonylaminocarbonyl)-4-methyl-5-methoxy-2,4-dihydro-3H-1,2,4-triazol-3-one of the formula (I) and/or of salts of the compound of the formula (I), and to the use of these compositions for the selective control of weeds in crops of cereals, in particular crops of wheat, and to methods for the selective control of weeds in crops of cereals by applying the compositions together with surfactants and/or customary extenders.

1 . Selective-herbicidal compositions, characterized in that they contain an effective amount of the compound 2-(2-trifluoromethoxy-phenyl-sulphonylaminocarbonyl)-4-methyl-5-methoxy-2,4-dihydro-3H-1,2,4-triazol-3-one of the formula (I) 
     
       
         
         
             
             
         
       
     
     and/or of salts of the compound of the formula (I). 
   
   
       2 . Selective-herbicidal compositions according to  claim 1 , characterized in that they contain an effective amount of the sodium salt of the compound of the formula (I). 
   
   
       3 . The use of the compound 2-(2-trifluoromethoxy-phenylsulphonyl-aminocarbonyl)-4-methyl-5-methoxy-2,4-dihydro-3H-1,2,4-triazol-3-one of the formula (I) according to  claim 1  and/or of salts of the compound of the formula (I) for the selective control of weeds in crops of cereals. 
   
   
       4 . The use of the sodium salt of the compound 2-(2-trifluoromethoxy-phenylsulphonylaminocarbonyl)-4-methyl-5-methoxy-2,4-dihydro-3H-1,2,4-triazol-3-one of the formula (I) according to  claim 1  for the selective control of weeds in crops of cereals. 
   
   
       5 . The use of the compound 2-(2-trifluoromethoxy-phenylsulphonyl-aminocarbonyl)-4-methyl-5-methoxy-2,4-dihydro-3H-1,2,4-triazol-3-one of the formula (I) according to  claim 1  and/or of salts of the compound of the formula (I) for the selective control of weeds in crops of wheat. 
   
   
       6 . Method for the selective control of weeds in crops of cereals, characterized in that the compound 2-(2-trifluoromethoxy-phenylsulphonylaminocarbonyl)-4-methyl-5-methoxy-2,4-dihydro-3H-1,2,4-triazol-3-one of the formula (I) according to  claim 1  and/or salts of the compound of the formula (I) are applied together with surfactants and/or customary extenders in crops of cereals.
