A liquid composition for application of a water-soluble exogenous chemical substance to foliage of a plant following dilution in a suitable volume of water, comprising a continuous aqueous phase, wherein is dissolved said water-soluble exogenous chemical substance in an amount which is biologically effective when the composition is diluted in said suitable volume of water and applied to said foliage, and wherein is dispersed a discontinuous oil phase that comprises (a) an adjuvant amount of a siloxane surfactant of formula (I) where x is an integer or average of integers of 0 to about 100, y is an integer or average of integers of 1 to about 30, each m is independently an integer of 1 to about 20, each n is independently an integer of 1 to about 30, each R group is independently a hydrogen or C1-6 hydrocarbyl group, each R' group is independently a hydrogen or C1-4 alkyl group, and each R" group is independently a C1-20 hydrocarbyl or acyl group, and (b) a substantially water insoluble organic solvent for said siloxane surfactant, in an amount such that substantially all of said siloxane surfactant is contained in or associated with said oil phase.
