Agrochemical concentrates containing alkyl polyglucoside and non-ionic surfactant

Abstract

This invention relates to a mixture of an alkyl polyglucoside with a (biological performance improving) adjuvant which is a non-ionic surfactant, the mixture improving the biological performance of an agrochemical. The biological performance effect of the alkyl polyglucoside is poorer than the partner adjuvant but the biological performance effect of the mixture is as good as that delivered by a much larger amount of that better, partner adjuvant alone.

1 . Use of a composition which is an SL (soluble liquid) to improve the biological performance of an agrochemical, or a salt of an agrochemical, which has a water solubility of less than 300 g/l at 25° C.; where the composition comprises:
 (i) an alkyl polyglucoside of formula (I) 
 
       
         
           
           
               
               
           
         
         
           where n is a mean value and is from 7 to 11; and m is a mean value and is from 1 to 3; and 
         
         (ii) a non-ionic surfactant which is not an alkyl polyglucoside and which has a Griffin HLB greater than or equal to 12; 
         where the concentration by weight of component (i) is greater than or equal to the concentration by weight of component (ii).
