ABSTRACT:
An aqueous suspension-type microcapsule insecticide composition which is obtained by emulsifying a hydrophobic admixture of liquid pyrethroid insecticide or a pyrethroid insecticide and a high boiling point solvent, preferably an alkyl ester of phthalic acid in which the alkyl group has 8-13 carbon atoms to form particles of a suitable size in the presence of an anionic water-soluble polymeric surface active agent and polycondensating melamine-formaldehyde or a derivative thereof on the surface of the said emulsified and dispersed particles, and a process for producing the composition. This composition exhibits stable insecticidal activity over a prolonged period with noticeably reduced toxicity to aquatic life.
