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 suspension 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 and R2 are independently linear hydrocarbyl chains each having 6 to about 22 carbon atoms, and R3 is hydrogen, a C1-5 hydrocarbyl group or a linear hydrocarbyl chain no longer than R1 and no longer than R2. The exogenous chemical substance is present in the composition in a first molar amount X1 in the form of said amphiphilic salt(s) and in a zero or second molar amount X2 in the form of one or more salt(s) having anions of the exogenous chemical substance and cations derived from one or more base(s) other than an amine compound of formula (I). X1 as a fraction of (X1 + X2) 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 desired biological activity, for example herbicidal activity, in a plant.
