(b) a liquid organic component;
wherein the inorganic compound component and/or organic biocide component in a) comprise a dispersion of particles in the liquid organic component, and wherein greater than 80 wt percent of the particles are micronized.
2 . The composition of claim 1 , wherein the composition comprises an organic biocide component selected from the group consisting of biocides listed in Table 1.
3 . The composition of claim 1 , wherein the composition comprises both an the inorganic compound component and an organic biocide component, and both of which are present as micronized particles.
4 . The composition of claim 1 wherein the composition comprises an inorganic compound component which comprises copper, one or more copper compounds, or combinations thereof.
5 . The composition of claim 4 , wherein the inorganic compound component is micronized and comprises one or more copper compounds that are selected from the group consisting of copper hydroxide, copper oxide copper carbonate, basic copper carbonate, copper oxychloride, copper 8-hydroxyquinolate, copper dimethyldithiocarbamate, copper omadine and copper borate.
6 .
