DESCRIPTION:
BRIEF SUMMARY
The present application relates to new active compound combinations composed, on the one hand, of prior-art .alpha.-butyl-.alpha.-(2,4-dichlorophenyl)-1H-1,2,4-triazole-1-ethanol (hexaconazole) and/or 5-[(4-chlorophenyl)methyl]-2,2-diethyl-1-(1H-1,2,4-triazol-1-yl-methyl)cyc lopentanol (metconazole) and, on the other hand, of further prior-art active compounds, the combinations being extremely suitable for the protection of industrial materials.
It has already been disclosed that .alpha.-butyl-.alpha.-(2,4-dichlorophenyl)-1H-1,2,4-triazole-1-ethanol (hexaconazole) has fungicidal properties.
Mixtures comprising hexaconazoles have also been disclosed (cf. EP 415 569, GB 2 119 653, EP 95 242, EP 289 356, EP 287 346).
The mixtures are used in the protection of plants and materials.
However, wood preservatives have to meet demands which exceed a simple fungicidal activity.
It was therefore the aim and object of the present invention to find a wood preservative which is highly active against wood-discolouring and wood-destroying fungi and against insects which damage wood, in particular wood-destroying longhorn beetles (Cerambycidae, Lyctidae, Bostrychidae and Anobiidae) including termites and which has a good long-term action, the activity of the fungicide not being adversely affected by the insecticide, or vice versa. Moreover, the wood preservative should have a good penetration capacity in the wood and the derived timber product.
It has been found according to the invention that these aims and objectives are achieved by a composition or concentrate for the preservation of wood and derived timber products which comprises hexaconazole in a mixture with a synergistically acting insecticide.
Preferably, at least one further azole fungicide is additionally added to this mixture.
The invention therefore relates to a wood preservative comprising .alpha.-butyl-.alpha.-(2,4-dichlorophenyl)-1H-1,2,4-triazole-1-ethanol and at least one synergistically acting insecticide.
Preferred is a wood preservative comprising hexaconazole and at least one synergistically acting insecticide and at least one further azole fungicide.
The wood preservatives comprise 0.01 to 25% by weight of hexaconazole and 0.00001 to 10% by weight of insecticide and, if appropriate, 0.1 to 99.9% by weight of azole fungicide. The wood preservatives furthermore generally comprise over 40% of a mixture of solvent and/or diluent and/or organochemical binder or fixative, processing auxiliaries, colorant, pigment, colorant mixture or pigment mixture.
Azoles which are preferred as components in the mixture are: ole -2-ol and/or hexaconazole or metconazole.
Particularly preferred mixtures comprise as azoles, in addition to hexaconazole, tebuconazole, propiconazole, cycproconazole and/or 2-(1-chloro-cyclopropyl)-1-(2-chlorophenyl)-3-1H-(1,2,4-triazol-1-yl)-prop an-2-ol, preferably in a ratio by weight to hexaconazole of 1:9 to 9:1.
Other very particularly preferred further fungicidal components in the mixtures are: (E)methoximino[.alpha.-(o-tolyloxy)-o-tolyl)]acetate, methyl (E)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4-yl-oxy]phenyl}-3-methoxyacrylate, methfuroxam, carboxin, fenpiclonil, 4-(2,2-difluoro-1,3-benzodioxol-4-yl)-1H-pyrrole-3-carbonitrile, butenafine and/or 3-iodo-2-propinyl n-butylcarbamate.
The following insecticides are used as synergistic insecticidal components in the mixtures: .alpha.-1(4-chlorophenyl)-4-(O-ethyl, S-propyl)phosphoryloxy-pyrazole, chlorpyrifos, coumaphos, demeton, demeton-S-methyl, diazinon, dichlorvos, dimethoate, ethoate. ethoprophos, etrimfos, fenitrothion, fenthion, heptenophos, parathion, parathion-methl, phosalone, phoxim, pirimiphos-ethyl, pirimiphos-methyl, profenofosm prothiofos, sulfprofos, triazophos and trichlorphon; methylcarbamate, butocarboxim, butoxycarboxim, carbaryl, carbofuran, carbosulfan, cloethocarb, isoprocarb, methomyl, oxamyl, pirimicarb, promecarb, propoxur and thiodicarb; 3-phenoybenzyl ethers, such as dimethyl-(4-ethoxyphenyl)silylmethyl 3-phenoxybenzyl ether, or for example, dimethyl-(9-ethoxy-phenyl)-
