Summary:A method of preparing a water-soluble or waterdispersible pesticidal composition is described. The pesticidal composition is prepared in a continuous process by intimately mixing a Bronsted acid precurso of the pesticidally active compound with a Bronsted base under reaction conditions in an extruder. The reaction is performed with minimal solvent and under conditions where the water of reaction volatilizes during the course of the reaction.
