摘要

A micronutrient composition intended for application to the foliage or branches of plants is described as containing oil-soluble overbased copper, molybdenum, zinc, manganese or iron naphthenates in a horticultural non-phytotoxic spray oil. The composition is made metathetically by mixing a solution of naphthenic acids, having an acid value ranging from about 90 to 280 mg.KOH/g., in a light aromatic solvent, with a methanolic sodium hydroxide solution and a methanolic solution of the desired metal salt of an inorganic acid; distilling off the methanol, the water and some of the aromatic solvent, adding the spray oil and removing the rest of the aromatic solvent. The ratio of equivalents of metal to naphthenate in these salts ranges from 1.1 to 20.
