ABSTRACT:
There is disclosed a herbicidal composition in which a foliar-applied herbicide is activated by the inclusion of a silicone glycol-silicone alkane terpolymer adjuvant. The composition provides enhanced phytotoxicity in the control of narrowleaf weeds, particularly Barnyardgrass, Quackgrass and Johnsongrass, and often also shows an improved degree of rainfastness relative to similar herbicidal compositions employing prior art silicone glycol adjuvants.
