Claims
- 1. A method for the protection of wood against insecticidal attack comprising the step of applying a synergistically effective amount of a mixture consisting of essentially of fipronil and one or more compounds of the formulae (IIa)-(IIh) onto and/or into said wood wherein said synergistically effective mixture of said fipronil and said one or more compounds of the formulae (IIa)-(IIh) are applied onto and/or impregnated into at least a portion of said wood by an impregnation process selected from the group consisting of a vacuum, a double vacuum and a pressure impregnation process.
- 2. The method of claim 1 wherein said fipronil and said one or more compounds of the formulae (IIa)-(IIh) are present in a concentration of 0.001 to 95% by weight of an insecticidal composition for the protection of products selected from the group consisting of wood products and timber products.
- 3. The method of claim 1 wherein said fipronil and said one or more compounds of the formulae (IIa)-(IIh) are in ratio of from 1:100 to 100:1.
- 4. The method of claim 2 wherein said fipronil and said one or more compounds of the formulae (IIa)-(IIh) are in ratio of from 1:100 to 100:1.
- 5. A method for the protection of wood against insecticidal attack comprising the step of applying a synergistically effective amount of a composition consisting essentially of fipronil and one or more compounds of the formulae (IIa)-(IIh) in a ratio of from 1:100 to 100:1 onto and/or into the wood to be protected.
- 6. The method of claim 5 wherein said synergistically effective mixture of said fipronil and said one or more compounds of the formulae (IIa)-(IIh) are applied onto and/or impregnated into at least a portion of said wood by an impregnation process selected from the group consisting of a vacuum, a double vacuum and a pressure impregnation process.
- 7. The method of claim 6 wherein said fipronil and said one or more compounds of the formulae (IIa)-(IIh) are present in a concentration of 0.001 to 95% by weight of an insecticidal composition for the protection of products selected from the group consisting of wood products and timber products.
- 8. A composition for the protection of an industrial material consisting essentially of a synergistically effective amount of fipronil and one or more compounds selected from the group consisting of
- 9. The composition of claim 8 consisting essentially of fipronil and the one or more compounds selected from the group consisting of thiacloprid, clothianidin, acetamiprid and nitenpyram in a ratio of 1:100 to 100:1.
- 10. A method for the protection of an industrial material against insecticidal attack comprising the step of applying a synergistically effective amount of a composition of claim 8 onto and/or into said industrial material.
- 11. The method of claim 10 wherein said industrial material is wood.
- 12. A process for preparing a composition for the protection of an industrial material comprising mixing a synergistically effective mixture consisting essentially of fipronil and one or more compounds selected from the group consisting of thiacloprid, clothianidin, acetamiprid and nitenpyram with one or more customary components of compositions for the protection of wood.
