Novel additives for agrochemical formulations

Abstract

The invention relates to an agrochemical composition comprising a compound of formula (I) [R-(A)x-OSO3−]-M+ (I); wherein M+ is a monoethanolammonium cation, and wherein the further variables have a meaning as defined herein. It also relates to an adjuvant solution comprising said compound of formula (I) and an organic solvent. Other objects are a compound of formula (I), wherein R is a linear alkyl and M+ is ethanolammonium and wherein the other variables have a meaning as defined herein; and a method of controlling undesired vegetation, and/or for regulating the growth of plants, wherein the agrochemical composition is allowed to act on the respective pests, their environment, or the crop plants to be protected from the respective pest, on the soil and/or on the crop plants and/or on their environment.

         M +  is a monoethanolammonium cation; and 
         the index x is a number from 1 to 10; 
         and an agrochemical active ingredient. 
       
     
     
         2 . The agrochemical composition according to  claim 1 , wherein the index x is from 1 to 3. 
     
     
         3 . The agrochemical composition according to  claim 1 , wherein R A , R B , R C , and R D  are H. 
     
     
         4 . The agrochemical composition according to  claim 1 , wherein the agrochemical active ingredient is glufosinate or (L)-glufosinate, or a salt thereof. 
     
     
         5 . The agrochemical composition according to  claim 1 , wherein the agrochemical active ingredient is a protoporphyrinogen-IX oxidase inhibitor or a salt thereof. 
     
     
         6 . The agrochemical composition according to  claim 1 , wherein the concentration of the compound of formula (I) in the agrochemical composition is more than 25 wt %. 
     
     
         7 . The agrochemical composition according to  claim 1 , wherein the concentration of the agrochemical active ingredient in the agrochemical composition is from 5 to 50 wt %. 
     
     
         8 . A compound of formula (I) as defined in  claim 1 , wherein
 R is a linear C 12 -alkyl; and   R A , R B , R C , and R D  are H; and   M +  is a monoethanolammonium cation.   
     
     
         9 . An adjuvant solution comprising a compound of formula (I) as defined in  claim 1 , and more than 10 wt % of an organic solvent. 
     
     
         10 . The solution of  claim 9 , wherein the organic solvent has a water-solubility of at least 10 wt % at 20° C. 
     
     
         11 . A method for controlling undesirable vegetation, which method comprises applying the agrochemical composition as defined in  claim 1  to a locus where undesirable vegetation is present or is expected to be present. 
     
     
         12 . The agrochemical composition according to  claim 4  wherein the agrochemical active ingredient is an ammonium salt of glufosinate or L-glufosinate.
