PROCESS AND COMPOSITIONS PROMOTING BIOLOGICAL EFFECTIVENESS OF EXOGENOUS CHEMICAL SUBSTANCES IN PLANTS

摘要

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 R<1> is hydrocarbyl group having 6 to about 22 carbon atoms, and R<2> and R<3> are independently hydrogen or C1-5 hydrocarbyl groups. The exogenous chemical substance is present in the composition in a first molar amount X<1> neutralised by said amine compound(s), in a zero or second molar amount X<2> neutralized by one or more base(s) other than an amine compound of formula (I), and in a zero or third molar amount X<3> in an acid form unneutralized by any base. X<1> as a fraction of (X<1> + X<2> + X<3>) 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.
