1. A composition comprising: a dispersion of solid particles of a substantially insoluble copper compound, andan organic biocide,wherein at least 20% of all particles of the composition have a particle size greater than 25 microns, andwherein the dispersion of solid particles of the substantially insoluble copper compound is in an amount from 0.001% to 10% by weight of the composition. 2. The composition of claim 1, wherein less than 20% of the particles of the composition comprise particles have a particle size greater than 100 microns. 3. The composition of claim 1, wherein the composition contains from 1% to 5% copper atoms by weight of the composition. 4. The composition of claim 1, wherein the copper compound comprises copper hydroxide, cupric oxide, cuprous oxide, copper carbonate, basic copper carbonate, copper oxychloride, copper dimethyldithiocarbamate, copper borate, or a combination thereof. 5. The composition of claim 1, wherein the composition further comprises a boric acid, a metal borate, a sodium borate, a potassium borate, or a combination thereof. 6. The composition of claim 1, wherein at least 30% of the particles of the composition have a particle size greater than 25 microns. 7. The composition of claim 1, wherein the composition contains no more than 36 grams volatile organic compounds (VOCs) per liter of wood preservative coating. 8. A method for remedial treatment of wood, comprising applying the composition of claim 1 to a wooden structure. 9. The method of claim 8, wherein the wooden structure is an in-service wood product. 10. The method of claim 8, wherein the composition is applied onto or into the wooden structure. 11. The method of claim 8, wherein the composition is applied with a brush. 12. The method of claim 9, wherein the in-service wood product is a utility pole, a railroad tie, or a wooden bridge. 13. A method comprising blending particles of a substantially insoluble copper compound; and an organic biocide; to produce a composition, wherein at least 20% of all particles of the composition have a particle size greater than 25 microns, wherein the composition contains from 1% to 5% copper atoms by weight of the composition. 14. The method of claim 13, wherein at least 30% of the particles of the composition comprise particles have a particle size greater than 25 microns. 15. The method of claim 13, wherein the copper compound comprises copper hydroxide, cupric oxide, cuprous oxide, copper carbonate, basic copper carbonate, copper oxychloride, copper dimethyldithiocarbamate, copper borate, or a combination thereof. 16. The method of claim 13, wherein the composition further comprises a boric acid, a metal borate, a sodium borate, a potassium borate, or a combination thereof. 17. The method of claim 13, wherein the substantially insoluble copper compound is in an amount from 0.001% to 10% by weight of the composition. 18. The method of claim 13, wherein less than 20% of the particles of the composition comprise particles having particle size greater than 100 microns. 19. A composition comprising: a dispersion of solid particles of a substantially insoluble copper compound, andan organic biocide,wherein at least 20% of all particles of the composition have a particle size greater than 25 microns, andwherein the composition contains no more than 36 grams volatile organic compounds (VOCs) per liter of wood preservative coating. 20. The composition of claim 19, wherein the composition contains from 1% to 5% copper atoms by weight of the composition.
