Abstract
Disclosed is a process for producing a flowable fungicide formulation comprising the steps of: (a) heating sufficiently a mixture of at least one solid active fungicidal compound with a hydrocarbon solvent and surfactant to form a melt; (b) adding sufficient aqueous solution to said melt to form a water-in-oil emulsion; (c) thoroughly mixing said emulsion in the presence of sufficient thickening agent to form a stable flowable fungicide formulation.

A process for producing a flowable fungicide formulation comprising the steps of:
- (a) heating at least one solid active fungicidal compound, a hydrocarbon solvent, and a surfactant to reduce the particle size of said solid fungicidal compound and to form a liquid melt from said mixture;
- (b) adding an aqueous solution to said melt to form a water-in-oil emulsion;
- and
- (c) thoroughly mixing said emulsion in the presence of an amount of a thickening agent to form a stable flowable fungicide formulation, said flowable fungicide formulation comprising from about 1% to about 50% by weight of active fungicidal compounds, from about 15% to about 40% by weight of said hydrocarbon solvent, from about 2% to about 10% by weight of said surfactant, from about 10% to about 50% by weight of water, and from about 0.25% to about 3% by weight of said thickening agent.

A process for producing a flowable fungicide formulation comprising the steps of:
- (a) heating a mixture of solid pentachloronitrobenzene, an isoparaffinic hydrocarbon solvent and an organophosphate ester surfactant to reduce the particle size of said solid pentachloronitrobenzene and to form a liquid melt from said mixture;
- (b) adding an aqueous solution comprising water and propylene glycol to said melt so as to form a water-in-oil emulsion;
- and
- (c) thoroughly mixing said emulsion in a high shear dispersator in the presence of a silica-containing thickening agent to form a stable flowable fungicide formulation, said flowable formulation comprising from about 1% to about 50% of total active fungicide compounds, from about 15% to about 40% by weight of said isoparaffinic hydrocarbon solvent from about 2% to about 10% by weight of said organophosphate ester surfactant, from about 10% to about 50% by weight of said water, from about 1% to about 10% by weight of propylene glycol, and from about 0.25% to about 3% by weight of said silica-containing thickening agent.
