1. A method of preserving wood comprising the steps of A) providing an aqueous wood preservative slurry comprising:a plurality of injectable first particulates of a solid copper compound, wherein the first particulates have a d96 of about 1 micron or less, a d99 of about 1.5 microns or less, and a d
1. A method of preserving wood comprising the steps of A) providing an aqueous wood preservative slurry comprising:a plurality of injectable first particulates of a solid copper compound, wherein the first particulates have a d96 of about 1 micron or less, a d99 of about 1.5 microns or less, and a d50 of greater than 0.02 microns; andB) injecting the aqueous wood preservative slurry into wood. 2. The method of claim 1, wherein the d50 is between about 0.05 microns and about 0.5 microns. 3. The method of claim 1, wherein the d50 is between about 0.1 microns and about 0.3 microns. 4. The method of claim 1, wherein the copper compound is selected from the group consisting of copper borate, basic copper carbonate, copper hydroxide, and a combination thereof. 5. The method of claim 1, wherein the copper compound is selected from the group consisting of tribasic copper sulfate, copper oxychloride, basic copper nitrate, basic copper phosphate, basic copper phosphosulfate, copper ferricyanide, copper ferricyanate, copper carbonate, copper borate, copper silicate, copper fluorosilicate, copper thiocyanate, copper boride and a combination thereof. 6. The method of claim 1, wherein the d96 of the first particulates is about 0.5 micron or less, the d99 is about 1 microns or less, and the d50 is between 0.05 microns and 0.4 microns. 7. The method of claim 1, wherein before the injecting step, the injectable first particulates are wet-milled in the presence of a liquid comprising a surface active agent and an effective amount of milling beads having a diameter between 0.1 mm and 0.8 mm and a density greater than about 3 grams/cm3. 8. The method of claim 1, wherein the aqueous wood preservative slurry further comprises an organic biocide, wherein at least a portion of the organic biocide is coated on the first particulates. 9. The method of claim 1, wherein the aqueous wood preservative slurry further comprises a plurality of injectable second particulates comprising a sparingly soluble in water organic biocide, wherein the second particulates have a d96 of about 1 micron or less and a d99 of about 1.5 microns or less. 10. The method of claim 9, wherein the d96 of the second particulates is about 0.5 micron or less, the d50 is between about 0.05 microns and about 0.4 microns. 11. The method of claim 9, wherein the organic biocide is selected from the group consisting of amitraz, deltamethrin, bifenthrin, chlorpyrifos, chlorpyrifosmethyl, cyfluthrin, cypermethrin, tralomethrin, betacyfluthrin, cyhalothrin, cambda-cyhalothrin, alpha-cypermethrin, triazophos, beta-cypermethrin, cyphenothrin, permethrin, phenothrin, cyproconazole, tetraconazole, dodemorph, difenoconazole, dimethomorph, fenarimol, diniconazole, myclobutanil, etridiazole, penconazole, flusilazole, prochloraz, imibenconazole, myclobutanil, triadimefon, propiconazole, azaconazole, tebuconazole, epoxyconazole, tridemorph, penpropimorph, triflumizole, chlorothalonil, imidacloprid, 3-iodo-2-propynyl butylcarbaamate, fludioxonil, azoxystrobin, thiabendazole, cyprodinil, isothiazolone, quaternary ammonium compound, and a combination thereof. 12. The method of claim 11, wherein the quaternary ammonium compound is selected from the group consisting of didecyldimethylammonium salt, benzyldimethyltetradecylammonium chloride, benzyldimethyldodecylammonium chloride, and didecyldimethylammonium chloride. 13. The method of claim 1, wherein the aqueous wood preservative slurry further comprises a plurality of injectable third particulates of a solid zinc compound, solid zinc oxide, solid iron oxide, or any mixture thereof, wherein the third particulates have a d96 of about 1 micron or less and a d99 of about 1.5 microns or less. 14. The method of claim 13, wherein the zinc compound is selected from the group consisting of zinc hydroxide; basic zinc carbonate, basic zinc phosphate, zinc borate, zinc oxychloride, zinc fluoroborate, zinc carbonate, zinc orthophosphate, zinc fluoride, and a combination hereof. 15. The method of claim 1, wherein said wood is lumber. 16. The method of claim 1, wherein said copper compound is a copper oxide.
