Patent ID: 7108848

Claim:
A fungicidal concentrate in a gel formulation comprising: (a) a liquid mixture ratio of about 1.2 to 16 parts by volume ultra pure water having an electrical resistance of 16–26 megohms, total dissolved solids of less than 0.04 parts per million and a specific conductance of less than 0.10 mho; (b) mixed with 1.2 to 16 parts by volume of catalyst micelles prepared by admixing a water soluble alkali metal silicate with an aqueous medium containing a dissolved substance which is a source of calcium ion and a dissolved substance which is a source of magnesium ion; the aqueous medium containing the dissolved substances in amounts to provide between about 1×10 −4 and 1×10 −1 mole per liter each of calcium ion and magnesium ion; the aqueous medium containing the dissolved substances in amounts to provide a molar ratio of calcium ion to magnesium ion between about 2.0:1.0 and 1.0:2.0; reacting the alkali metal silicate with the dissolved substances providing calcium ion and magnesium ion to produce an aqueous suspension of finely divided particles of the reaction product; admixing a micelle-forming surfactant with the aqueous medium in an amount to form catalyst micelles comprising the finely divided particles of the reaction product upon agitating the aqueous medium; and agitating the aqueous medium containing the finely divided particles of the reaction product and surfactant to form the catalyst micelles; and (c) mixing the product of (a) and (b) with one liter of a gel formulation ingredient and 5–40% by weight urea based on the weight of the gel formulation ingredient.
