First claim
Opening claim text (preview).
The invention claimed is: 1. A method for the prevention and/for treatment of growth and/or infestation of a fungus on a wallboard comprising treating said wallboard with a fungicidally effective amount of difenoconazole and a further fungicide selected from the group consisting of propiconazole; fludioxonil; thiabendazole; and cyprodinil, wherein said difenoconazole and said further fungicide are present in synergistically effective amounts. 2. The method according to claim 1 wherein the fungus is selected from the group consisting of: Aspergillus sp.; Alternaria sp.; Aureobasidium sp.; Cladosporium sp.; Memnionella sp.; Oligoporus sp.; Penicillium sp.; and Stachybotrys sp. or combinations thereof. 3. The method according to claim 1 wherein the wallboard comprises a gypsum core and wherein said difenoconazole is included in the gypsum core of said wallboard. 4. The method according to claim 1 wherein the wallboard comprises a gypsum core and wherein said further fungicides are included in the gypsum core of said wallboard. 5. The method according to claim 1 wherein the wallboard comprises a paper coating and wherein the difenoconazole is included in the paper coating of the wallboard. 6. The method according to claim 1 wherein the wallboard comprises a paper coating core and wherein the further fungicides are included in the paper coating of the wallboard. 7. Wallboard that has been treated with a fungicidally effective amount of difenoconazole and a further fungicide selected from the group consisting of propiconazole; fludioxonil; thiabendazole; and cyprodinil, wherein said difenoconazole and said further fungicide are present in synergistically effective amounts. 8. Wallboard according to claim 7 wherein the wallboard comprises a gypsum core and wherein the difenoconazole is included on the surface of the gypsum core of the wallboard. 9. Wallboard according to claim 7 wherein the wallboard comprises a gypsum core and wherein the further fungicides are included on the surface of the gypsum core of the wallboard. 10. Wallboard according to claim 7 wherein the wallboard comprises a paper coating core and wherein the difenoconazole is included in the paper coating of the wallboard. 11. Wallboard according to claim 7 wherein the wallboard comprises a paper coating core and wherein the further fungicides are included in the paper coating of the wallboard.
