Abstract: A method for treating wood with an aqueous composition having fungicidal and insecticidal properties. The aqueous composition comprises(a) at least one oil-soluble metal salt of an organic carboxylic acid having fungicidal properties wherein the metal is zinc, chromium, iron, antimony, lead, mercury or a mixture thereof,(b) at least one halopyridyl phosphate of the formula ##STR1## wherein R represents a halopyridyl group, Z represents oxygen or sulfur, and each R' is independently a lower alkoxy, amino or lower alkylamino group,(c) at least one surfactant, and(d) from about 60 to 99% of water.Such compositions penetrate into both dry and green wood rather readily, and the result is wood which is resistant to fungi and insects.

Abstract: A process for impregnating green wood with oil-soluble metal salts is described. The method comprises(a) contacting the green wood with an aqueous system comprising(i) water,(ii) at least one oil-soluble metal salt of an organic carboxylic acid, and(iii) at least one surfactantfor a period of time sufficient to enable the metal salt to penetrate into the wood, and(b) removing the wood from contact with the aqueous system. Good penetration of the metal salt into the green wood is realized by this method when conducted under vacuum, at atmospheric pressure or at elevated pressures. Preferably, the metal salt is a preservative such as a fungicide, and the aqueous system also contains other desirable components such as fire retardants, coloring agents and insecticides.

Abstract: An aqueous composition having fungicidal and insecticidal properties is described which is useful particularly for treating wood. The aqueous composition comprises(a) at least one oil-soluble metal salt of an organic carboxylic acid having fungicidal properties wherein the metal is zinc, chromium, iron, antimony, lead, mercury or a mixture thereof,(b) at least one halopyridyl phosphate of the formula ##STR1## wherein R represents a halopyridyl group, Z represents oxygen or sulfur, and each R' is independently a lower alkoxy, amino or lower alkylamino group,(c) at least one surfactant, and(d) from about 60 to 99% of water.Such compositions penetrate into both dry and green wood rather readily, and the result is wood which is resistant to fungi and insects.
