The invention discloses as new fungicidal compositions of matter dispersed micelles of overbased copper naphthenates in non-phytotoxic spray oils prepared metathetically. Each micelle contains a combined alkaline earth metal to reduce phytotoxicity of the dispersions. The alkaline earth metal may be present partly as naphthenate in the outer protective layer of the dispersed micelles. The inner core of the micelle is mainly copper hydroxide but some alkaline earth metal hydroxide may also be present. The mole percent of alkaline earth metal to copper ranges from about 1 to about 7 and the preferred metal is calcium. The micelles form clear fungicidal dispersions in spray oils.
