摘要

(WO9955505) A method of inhibiting sapstain in wet wood comprises applying to the surface of the wood a composition comprising a solution or microemulsion comprising at least one mobile fungicide which will diffuse into the surface of the wood.  Preferably the fungicide is methylene bisthiocyanate, optionally in combination with an isothiazolione.  The composition also comprises a surfactant and organic solvent or water.

主权利要求

(WO9955505) 1. CLAIMS 1. A method of inhibiting sapstain in wet wood comprising applying to the surface of the wood a composition comprising a solution or microemulsion (as herein defined) comprising at least one mobile fungicide which will diffuse into the surface of the wood. 2. A method according to claim 1 wherein said fungicide is methylene bisthiocyanate . 3. A method according to either one of claims 1 and 2 wherein the composition is an oil in water microemulsion. 4. A method according to either one of claims 1 and 2 wherein the composition comprises an organic solvent. 5. A method according to claim 4 wherein the solvent comprises dimethyl sulphoxide, N-methyl pyrrolidone, or dimethyl formamide. 6. A method according to claim either one of claims 1 and 2 wherein the_ solvent comprises kerosene, benzene, chloroform, toluene, ether, carbon disulphide, acetone, paraffin, diesel, white spirit, soya oil, linseed oil, or fish oil. 7. A method according to either one of claims 1 to 6 wherein the composition comprises a surfactant. 8. A method according to claim 7 wherein the composition comprises a quaternary ammonium salt as a surfactant. 9. A method according to claim 7 wherein the composition comprises benzalkonium chloride or didecyldimethyl ammonium chloride as a surfactant. 10. A method according to claim 7 wherein the composition comprises a combination of didecyldimethyl ammonium chloride and nonyl phenol ethoxylate as a surfactant. 33 1 1. A method according to any one of claims 1 to 10 wherein the composition also comprises a fungicide which will remain on the surface of the wood in addition to the mobile fungicide which will penetrate into the wood. 12. A method according to claim 11 wherein the further fungicide is selected from substituted benzimidazoles including carbendazim (methyl benzimidazol-2- ylcarbamate) and chemical precursors of benzimidazoles including benomyl (methyl l-(butycarbonyl) benzimidazol-2ylcarbamate or copper-8- hydroxyquinolinolate; triazoles including hexaconazole ((RS)-2-(2,4- dichlorophenyl)- l-(lH-l,2,4-triazole-l-yl) hexan-2-ol); and quaternary ammonium compounds including didecyldimethyl ammonium chloride, chlorothalonil (tetrachloroisophthalonitrile) , fenpropimorph and isothiazolinones. 13. A method according to any one of claims 1 to 12 wherein the composition also comprises a hydrophobic substance which will act as a water barrier on the surface of the wood. 14. A method according to claim 13 wherein said water barrier substance is selected from lanolin, petrolatum, paraffin oils, fish oils, animal oils, waxes, silicones, fatty acid eaters, bitumen, vegetable fats and oils and wool grease. - — 15. A method according to any one of claims 1 to 14 wherein the mobile fungicide penetrates 10 - 20mm into the surface of the wood. 16. A method according to any one of claims 1 to 15 wherein the mobile fungicide penetrates into the wood at a rate greater than the rate of penetration by sapstain fungi. 17. A method according to any one of claims 1 to 16 wherein the composition is applied to logs within 10 days of felling. 18. A method according to any one of claims 1 to 16 wherein the composition is applied to logs within 5 days of felling. 34 19. A method according to any one of claims 1 to 16 wherein the composition is applied to logs within 2 days of felling. 20. A method according to any one of claims 4 to 19 wherein the composition is applied by dipping or spraying. 21. A method according to any one of claims 1 to 20 wherein the composition is applied to wood at a rate in the range 200-500 ml of antisapstain treatment solution per m2of wood surface area. 22. A method according to any one of claims 1 to 20 wherein the strength of the composition is adjusted to achieve a surface retention of the mobile fungicide of 10-300 micrograms per cm2. 23. An antisapstain composition suitable for application to wood, which is a microemulsion or surfactant assisted solution and comprises: (a) 0.05- 1% of methylene bisthiocyanate, (b) 0. 1- 10% of a solvent, (c) 0.1 to 15% of a surfactant, and (d) up to 99.75% water. 24. An antisapstain composition according to claim 23 wherein said solvent comprises dimethyl sulphoxide, N-methyl pyrrolidone, or dimethyl formamide. 25. An antisapstain composition according to claim 23 or claim 24 wherein said surfactant is a quartenary ammonium salt. 26. An antisapstain composition according to any one of claims 23 to 25 also including 1-40% of a water barrier hydrophobic substance as a water barrier. 27. An antisapstain concentrate composition comprising: (a) 10-40% (w/w) of a hydrophobic substance as a water barrier, 35 (b) 0.5- 15% of a surfactant, (c) 1- 10% of an organic solvent, (d) 0.2-5% methylene bisthiocyanate, and (e) 30-88.3% water. 28. An antisapstain composition containing 1- 10% methylene bisthiocyanate dissolved in a vehicle containing 10-90% dimethyl sulphoxide, N-methyl pyrrolidone, or dimethyl formamide, and 10-90% of a quaternary ammonium salt as a surfactant. 29. An antisapstain concentrate composition comprising a mobile fungicide which will penetrate into the surface of the wood, about 10% to 40% of a water barrier substance, about 60% to 90% of either an organic solvent, or water or a water based formulation. 36
