The invention relates to an agent for impregnating wood and wood materials based on one or more fungicidal tetravalent organotin compounds and at least one organic chemical insecticide based on carbamate and / or phosphoric acid ester, thiophosphoric acid ester or solvent and thionophosphoric acid ester, and at least one organic contains as additives colorants, pigments, water-repellent agents, perfumes and inhibitors or corrosion inhibitors, the impregnating agent additionally containing phosphoric acid, preferably orthophosphoric acid, and / or a partial acid-reactive ester thereof.

It is already known to use fungicidal, tetravalent, organotin compounds in wood preservatives and to use these compounds in combination with other insecticidal active ingredients in wood impregnation.

DE patent 1,042,945 discloses a pesticide for small pests and plants which, in addition to the biocidal active ingredient, contains a water-immiscible liquid, water, resin, emulsifier and filler. This is a spray mixture that is not intended as a wood preservative.

2,69586 NL 6,505,966 discloses a fungicide based on mixtures of triphenyltin compounds and dithiocarbamate compounds, which mixture may also contain other substances such as acetates, hydroxides, proteins, etc. to reduce phytotoxicity. It is a plant protection product whose stability and application requirements are completely different from those of wood preservatives.

PR patent 1,234,448 discloses wood preservatives which are in accordance with the introduction to this specification but in which the present problem has not been solved; DE 2,438,334 discloses the addition of lithium compounds as a marker; DE patent 1,918,846 discloses the protection of fresh wood with an aqueous plastic dispersion; DE-A-2,438,946 discloses a double vacuum process and a substance based on tributyltin compounds, pentachlorophenol and lindane. These publications do not show how the present problem would have been solved.

DE-OS 2,454,531 further discloses a pesticide preparation for wood protection, which mainly contains 5 to 50 parts of oil or synthetic resins, 0 to 6 parts of pigments, 1 to 10 parts of pesticides and 40 to 85 parts of a conventional a solvent based on petroleum, or a mixture of such solvents, and in addition 2 to 20% by weight of N-methyl-2-pyrrolidone, calculated on the sum of the other components.

It can be read from said patent publication DE-OS 2.454.531 that the use of resins, e.g. alkyd resin, in fungicidal wood preservatives also makes it more difficult for the active component to penetrate the wood. Therefore, in order to avoid this disadvantage, N-methyl-2-pyrrolidone must be added to avoid this disadvantage.

However, within the scope of the invention, it has been found that the fungicidal, tetravalent, organotin compounds together with the insecticidal carbamate and / or phosphoric acid ester, thiophosphoric acid ester or a thionophosphoric acid ester after a certain , which lead to turbidity of the wood preservative, in some cases precipitation or a reduction in the effect.
