Abstract
Compositions in the form of an aqueous solution comprising: (a) a compound of a preservative metal; (b) a branched-chain carboxylic acid or a dipentene-mono-carboxylic acid or a dipentene-di-carboxylic acid; and (c) ammonia and/or an ammonium compound, the amount of ammonia and/or ammonium compound being at least sufficient to solubilize the compound (a) and to neutralize the acid (b), are useful for the preservation of wood and like materials by impregnation into or surface application to the material and are also useful as fungicides for the treatment of plants for agricultural and horticultural use.
Claims58
In an aqueous ammoniacal preservative composition comprising:
- p1 (a) a composition of a preservative metal selected from the group consisting of copper, zinc, cobalt, iron, manganese and nickel;
- (b) an organic acid;
- and
- (c) an ammoniacal compound selected from the group consisting of ammonia, ammonia compounds, and mixtures thereof, the amount of ammoniacal compound being at least sufficient to solubilize said compound (a) and to neutralize said acid (b), the improvement wherein said organic acid is a branched chain carboxylic acid having 6 to 20 carbon atoms, a dipentene monocarboxylic acid, a dipentene dicarboxylic acid, or a mixture thereof present in a preserving amount.
In an aqueous ammoniacal preservative composition comprising:
- (a) a composition of a preservative metal selected from the group consisting of copper, zinc, cobalt, iron, manganese and nickel;
- (b) an organic acid;
- and
- (c) an ammoniacal compound selected from the group consisting of ammonia, ammonia compounds and mixtures thereof, the amount of ammoniacal compound being at least sufficient to solubilize said compound (a).
- the improvement wherein said organic acid is a branched chain carboxylic acid having 6 to 20 carbon atoms, a dipentene monocarboxylic acid, a dipentene dicarboxylic acid or a mixture thereof present in a preserving amount.
A process for protecting seeds and growing plants against fungal attack which comprises applying to the seeds and the growing plants an aqueous solution comprising:
- (a) a compound of copper;
- (b) an organic acid selected from the group consisting of branched-chain carboxylic acids, dipentene mono-carboxylic acids, dipentene di-carboxylic acids and mixtures thereof;
- and
- (c) an ammoniacal compound selected from the group consisting of ammonia, ammonium compounds and mixtures thereof, the amount of ammoniacal compound being sufficient to solubilize said compound (a) and to neutralize said acid (b).
