POSTEMERGENT HERBICIDE COMPOSITIONS CONTAINING ACETOXY-TERMINATED SILICONE GLYCOL AND DISPERSANT

摘要

There is disclosed a herbicide composition in which a postemergent herbicide is activated by the inclusion of a silicone glycol adjuvant consisting essentially of (i) a silicone glycol having an average structure <IMG> wherein Me denotes a methyl radical, and (ii) a silicone glycol dispersant compound for component (i). When compared to similar prior art silicone glycol adjuvants not having an acetoxy terminated glycol chain, the compositions of the present invention provide enhanced rainfastness in the control of weeds, particularly velvetleaf plants.
