DESCRIPTION:
BRIEF SUMMARY
This invention relates to preservative for wood and other cellulosic materials.
The use of biocidal metal ions in wood preservation is well known. There are also many compounds containing a triazole group which are known to possess biocidal properties.
BRIEF DESCRIPTION OF THE FIGURES
FIG. 1 is a graph correlating the additive and synergistic effects of a loading of hypothetical compound X relative to a loading of hypothetical compound Y. Points A and B are the toxic index values for biocidal compounds Y and X respectively. The straight line between the two points illustrates the toxic index values which would be obtained if the biocidal effects of compounds X and Y were merely additive.
FIG. 2 is a graph correlating the loading of tebuconazole (Kg/m.sup.3) and the loading of copper (Kg/m.sup.3). The dotted line illustrates the expected concentration of cuprammonium compound and tebuconazole which would be needed in a composition containing copper and tebuconazole at a weight ratio of 25:1 if the performance of copper and tebuconazole were merely additive. The solid line illustrates the actual concentrations found to be required.
FIG. 3 is a graph correlating the retention of copper (Kg/m.sup.3) and the retention of tebuconazole (Kg/m.sup.3). The line with broad dashes illustrates a theoretical line of effectiveness assuming that the performance of copper and tebuconazole are merely additive. The line with narrow dashes illustrates the actual line of effectiveness. The solid lines illustrate the ratio of cuprammonium compound to tebuconazole.
FIG. 4 is a graph correlating the loading of tebuconazole (Kg/m.sup.3) and the loading of copper (Kg/m.sup.3). The dotted line illustrates the expected concentrations of cuprammonium compound and tebuconazole at a weight ratio of 25:1 if the performance of copper and tebuconazole were merely additive. The solid line illustrates the actual concentrations found to be required.
FIG. 5 is a graph correlating the loading of propiconazole (Kg/m.sup.3) and the loading of copper (Kg/m.sup.3). The dotted line illustrates the expected concentrations of cuprammonium compound and propiconazole at a weight ratio of 25:1 if the performance of copper and propiconazole were merely additive. The solid line illustrates the actual concentrations found to be required.
FIG. 6 is a graph correlating the loading of azaconazole (Kg/m.sup.3) and the loading of copper (Kg/m.sup.3). The dotted line illustrates the expected concentrations of cuprammonium compound and azaconazole at a weight ratio of 25:1 if the performance of copper and azaconazole were merely additive. The solid line illustrates the actual concentrations found to be required.
According to the present invention there are provided preservative compositions comprising a biocidal metal compound and a fungicidal compound containing a triazole group wherein the weight ratio of metal atom: fungicidal compound containing the triazole group is at least 1:2.5; with the specific exceptions of (i) composition (a) which contains 1.320% by weight of sodium nitride, 1.190% by weight of copper sulphate. 5H.sub.2 O, 0.400% by weight of boric acid, 0.625% by weight of sodium heptonate, 0.390% by weight of sodium hydroxide, 0.012% by weight of tebuconazole, 0.391% by weight of surfactant blend in xylene and 95.762% by weight of water and (ii) composition (b) which contains 0.00025% by weight of a compound of formula: ##STR1## 0.025% by weight of a compound of formula ##STR2## 2.525% by weight of dimethylformamide, 0.006313% by weight of alkylarylpolyglycolether the remainder being water.
We have found that compositions according to the invention possess advantageous properties: in particular, it has been found that the metal compound and the fungicidal compound containing the triazole group (hereinafter "the triazole compound") exhibit synergistic fungicidal activity.
It will be understood that the metal compound may be present in a form such that metal ions are free in solution or may form part of a complex. Similarly, the triazole compound m
