Plant treatment composition containing supramolecular aggregates of amine salts of exogenous chemical compound such as N-phosphonomethylglycine

摘要

A plant treatment composition for application to foliage of a plant to elicit a desired biological response comprises an aqueous application medium having colloidally dispersed supramolecular aggregates comprising one or more amphiphilic salt(s) having anions of an anionic exogenous chemical substance and cations derived by protonation of one or more amine compound(s). Each amine compound has the formula (I) wherein: R1 and R2 are independently linear hydrocarbyl chains of 6 to 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 composition contains the exogenous chemical substance in a first molar amount X1 in the form of the 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). The total molar amount (X1 + X2) of the exogenous chemical substance in salt form being sufficient to elicit the desired biological response when the composition is applied to the foliage of the plant at a rate from about 10 to about 1000 liters per hectare, and X1 as a fraction of (X1 + X2) being about 0.01 to 1. The exogenous chemical substance can be 3,4,4-trifluoro-3 -butenoic acid, N-(3,4,4-trifluoro-1-oxo-3-butenyl)glycine, N-phosphonomethylglycine or DL-homoalanin-4-yl-(methyl)phosphinate. .
