Abstract
Complexes of herbicidal carboxylic acids and amine-containing polymers or oligomers are provided. These herbicidal complexes are useful for controlling unwanted plant growth. The herbicidal complexes have low solubility in water, low volatility relative to commercial compositions of the corresponding herbicidal carboxylic acids, and offer similar or improved herbicidal performance when compared to existing salts of the herbicidal carboxylic acids.

13. A method for reducing the eye irritating properties of aqueous herbicidal concentrates of alkylamine salts of herbicidal carboxylic acids derived from mono-, di- or trialkylamines comprising adding an amine-containing polymer or oligomer to the herbicidal carboxylic acid to form a complex of the herbicidal carboxylic acid and the amine-containing polymer or oligomer.

14. A method for reducing spray drift of a solution containing a herbicidal carboxylic acid comprising adding an amine-containing polymer or oligomer to the solution containing the herbicidal carboxylic acid to form a complex of the herbicidal carboxylic acid and the amine-containing polymer or oligomer and spraying the complex.

15. A method for improving the binding to plant surfaces of alkylamine salts of herbicidal carboxylic acids derived from mono-, di-, or trialkylamines comprising adding an amine-containing polymer or oligomer to a solution containing the herbicidal carboxylic acid to form a complex of the herbicidal carboxylic acid and the amine-containing polymer or oligomer and applying the complex to the plant surfaces.
