Abstract
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 polyamine(s) or polyamine derivative(s) each having (a) at least two nitrogen-containing groups, of which a number n not less than 1 are amino groups that can be protonated to form cationic primary, secondary or tertiary ammonium groups, and (b) at least one hydrocarbyl or acyl group having about 6 to about 30 carbon atoms. The composition contains (i) a molar amount X in total of the exogenous chemical substance, in all salt and acid forms thereof present, sufficient to elicit a biological response when the composition is applied to the foliage of the plant at a rate of about 10 to about 1000 l/ha, (ii) a molar amount A in total of said polyamine(s) and derivative(s) thereof and cations derived therefrom, and (iii) a zero or molar amount B in tot…
