A plant treatment composition for application of an anionic exogenous chemical substance such as glyphosate herbicide to foliage of a plant is provided. The composition is a colloidal dispersion having supramolecular aggregates dispersed in an aqueous application medium. The supramolecular aggregates comprise one or more amphiphilic salt(s) having anions of the exogenous chemical substance and cations derived by protonation of one or more amine compound(s) each having formula (I), wherein R1 is hydrocarbyl group having 6 to about 22 carbon atoms, and R2 and R3 are independently hydrogen or C1-5 hydrocarbyl groups. The exogenous chemical substance is present in the composition in a first molar amount X1 neutralised by said amine compound(s), in a zero or second molar amount X2 neutralized by one or more base(s) other than an amine compound of formula (I), and in a zero or third molar amount X3 in an acid form unneutralized by any base X1 as a fraction of (X1 + X2 + X3) is about 0.01 to 1. Also provided are a liquid concentrate composition which, upon dilution with water, forms a plant treatment composition, and a process for making such a liquid concentrate composition. Plant treatment compositions of the invention are useful for eliciting a biological activity, for example herbicidal activity, in a plant.
