Selective herbicides based on substituted thien-3-yl-sulphonylamino(thio)carbonyltriazolin(thi)ones and safeners

Abstract

The invention relates to selective herbicidal compositions that comprise an effective amount of an active compound combination comprising (a) one or more compounds of the formula (I) in which Q 1 , Q 2 , R 1 , R 2 , R 3 and R 4 are as defined in the disclosure—and salts of the compounds of the formula (I)— and (b) at least one of the crop-plant-compatibility-improving compounds listed in the disclosure. The invention further relates to the use of these compositions for controlling undesirable vegetation and to a process for preparing the compositions according to the invention.

1 . A composition comprising an active compound combination comprising
 (a) a compound of formula (I)   
       
         
           
           
               
               
           
         
         or a salt thereof 
         and 
         (b) the crop-plant-compatibility-improving compound isoxadifen-ethyl, wherein the ratio of isoxadifen-ethyl per part by weight of said compound of formula I or a salt thereof is from 0.1 to 50. 
       
     
     
         2 . The composition of  claim 1 , wherein the ratio of isoxadifen-ethyl per part by weight of said compound of formula I or a salt thereof is from 1 to 25. 
     
     
         3 . The composition of  claim 1 , further comprising one or more of extenders, solid carriers, emulsifiers, foam-formers, dispersants, tackifiers, colorants, mineral oil, or vegetable oil. 
     
     
         4 . The composition of  claim 1 , further comprising another herbicide, fungicide, insecticide, acaricide, nematicide, bird repellent, growth factor, and/or plant nutrient and agent. 
     
     
         5 . The composition of  claim 1 , wherein component (a) and component (b) are the only two actives present in the composition. 
     
     
         6 . The composition of  claim 1 , wherein component (a) is the only herbicide present in the composition. 
     
     
         7 . A method for controlling undesirable plants comprising allowing an effective amount of the composition according to  claim 1  to act on undesirable plants and/or their habitat. 
     
     
         8 . A process for preparing a herbicidal composition comprising mixing the composition according to  claim 1  with one or more surfactants and/or extenders. 
     
     
         9 . The method according to  claim 7 , wherein the undesired plants are controlled in areas of growing maize. 
     
     
         10 . The method according to  claim 9 , wherein 0.001 to 5 kg per ha of the composition are applied. 
     
     
         11 . The method according to  claim 9 , wherein 0.001 to 1 kg per ha of the composition are applied. 
     
     
         12 . The method according to  claim 9 , wherein 0.003 to 0.5 kg per ha of the composition are applied. 
     
     
         13 . The method according to  claim 9 , wherein the composition is applied pre-emergence. 
     
     
         14 . The method according to  claim 9 , wherein the composition is applied post-emergence.
