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.
Claims21
A method of rendering wood resistant to fungus and insects comprising
- (a) contacting the wood with an aqueous system comprising
- (i) 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,
- (ii) at least one halopyridyl phosphate of the formula ##STR5## wherein R represents a halopyridyl group, Z represents oxygen or sulfur, and each R' is independently a lower alkoxy, amino or lower alkylamino group,
- (iii) at least one surfactant, and
- (iv) from about 60 to 99% of water for a period of time sufficient to enable the metal salt and halopyridyl phosphate to penetrate into the wood, and
- (b) removing the wood from contact with the aqueous system.
A method of rendering wood resistant to fungus and insects comprising
- (a) contacting the wood with an aqueous system comprising
- (i) about 0.1 to 25% of at least one oil-soluble metal salt of an organic carboxylic acid wherein the metal is zinc, chromium, iron, antimony, lead, mercury, or a mixture thereof,
- (ii) about 0.05 to 15% of at least one halopyridyl phosphate of the formula ##STR6## wherein R represents a halopyridyl group, Z represents oxygen or sulfur and each of R' is independently a lower alkoxy, amino or lower alkylamino group,
- (iii) about 0.25 to 7.5% of at least one surfactant,
- (iv) about 60 to 99% of water, and
- (v) less than about 20% of a hydrocarbon solvent
- for a period of time sufficient to enable the metal salt and halopyridyl phosphate to penetrate ino the wood, and
- (b) removing the wood from contact with the aqueous system.
