ABSTRACT:
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 of 4 or 5 ethylene oxide units in its glycol chain and (ii) a silicone glycol dispersant compound for component (i). The composition provides enhanced phytotoxicity in the control of weeds, particularly velvetleaf plants, and shows an improved degree of rainfastness relative to prior art compositions.
