Abstract
The present application relates to aqueous compositions for controlling a plant disease caused by a phytopathogenic organism, to methods of preparing such compositions and to uses of such compositions, for example for controlling a plant disease caused by a phytopathogenic organism. The aqueous compositions comprise copper ions, phosphorous acid and/or a salt thereof and an effective amount of an amine selected from an alkylamine, an alkanolamine and mixtures thereof. The pH of the compositions is from about 6 to about 10.
Claims20
An aqueous composition for controlling a plant disease caused by a phytopathogenic organism, the composition comprising:
- (a) copper ions;
- (b) phosphorous acid and/or a salt thereof;
- and
- (c) an alkylamine,
- wherein the aqueous composition is prepared by combining a source of copper ions in an amount of from about 0.5 wt % to about 5 wt %;
- the phosphorous acid in an amount of about 18 wt % and an effective amount of the alkylamine,
- wherein
- the alkylamine is ethylenediamine and the effective amount of the ethylenediamine is from about 10 wt % to about 15 wt %, or
- the alkylamine is triethylenetetramine and the effective amount of the triethylenetetramine is from about 7 wt % to less than 20 wt %, or
- the alkylamine is 1,3-diaminopropane and the effective amount of the 1,3-diaminopropane is about 10 wt % to about 15 wt %;
- and
- wherein the pH of the composition is from about 6 to about 10, and all wt % are based on the total wt of the composition.
